• Loss of network connectivity when playing video on Optoma HD180 projector

  - by Jeff Fohl

  Hi Folks - New to Super User, so I hope this question fits in with the guidelines. Very strange problem I am having, and I am at a loss as to how to continue troubleshooting this one. The basic problem is that when I attempt to watch streamed video on a particular display device (an Optoma HD180 projector), my network connectivity drops like a stone to barely measurable levels. This is my setup: I have a Dell H2C 730x running Windows 7 64bit. This particular computer has two ATI Radeon HD 4800 video cards. I have two Samsung 22" monitors connected to one card, and an Optoma HD180 digital projector connected to the other card via an HDMI cable. My internet connection is normally a reliable 6Mbps. The problem I am having occurs when I stream video (or even just browse the web) on the Optoma Projector. When I do this, my internet connection drops to practically zero (just a few kilobits per second). When I move the browser away from the projector, and over to one of my Samsung monitors, the internet connection comes right back. Note that the Optoma projector is on and enabled as a third monitor all this time. I can move the mouse around on the projector without triggering the problem. I tried pinging my router when I was playing a movie on one of the monitors, and I get a 1 millisecond response. However, when I have the movie playing on the Optoma projecter, pinging the router gives me response times in the hundreds of milliseconds, or times out completely. So, it clearly is something local to my machine - and not some sort of throttling occurring down the line. I would think that it is possibly something to do with the HDMI driver conflicting somehow with my network driver (which is a USB-based wireless connection). This one has me really stumped. Anyone have any ideas?

• Backing up SQL NetApp Snapshots using TSM

  - by WerkkreW

  In our environment we have a 3 node SQL 2005 Cluster which is on NetApp storage. We are currently using SMSQL (NetApp SnapManager for SQL) to take Snapshot backups of the data. This works great, but due to some audit requirements we are also forced to maintain some copies on tape. We have used NDMP in other places across the enterprise but we do not want to use it in this specific instance. Basically what I need to do is, get the most recent snapshot copy of the databases on tape, via Tivoli Storage Manager (TSM). What I have done is, obtained a basic Windows Server 2003 VM with SnapDrive installed, which is SAN attached and zoned to the NetApp, and I have written a batch file to do the following: Mount the latest __RECENT snapshot lun to the host, using a specific drive letter Perform a TSM based incremental backup Dis-mount the LUN This seems to work fine, except sometimes the LUN's do not mount due to some sort of timeout. Also, due to my limited knowledge of windows batch scripting, I have no way to monitor the success or failure of these backups since I do not know how to send a valid return code back to the TSM scheduling service. Is there a more efficient/elegant way to accomplish this without NDMP?

• Is it a good idea to run Redmine using Webrick through Nginx?

  - by Rohit

  The task here is to get Redmine setup for a small (<20) team. There may be a few users who would access the setup as business clients. I am familiar with setting up PHP for Apache, and recently, Nginx. I am not familiar with Ruby, Ruby-On-Rails, etc. I prefer to use the OS's (Ubuntu Linux LTS) package manager to install the different components as it takes care of dependencies and updates. I have setup Nginx with PHP-FPM successfully and am struggling with Redmine. As suggested here, I got Redmine running on port 3000. # /etc/init/redmine.conf # Redmine description "Redmine" start on runlevel [2345] stop on runlevel [!2345] expect daemon exec ruby /usr/share/redmine/script/server webrick -e production -b 0.0.0.0 -d And using the Nginx config on this page, I used Nginx to proxy requests to Webrick. server { listen 80; server_name myredmine.example.com; location / { proxy_pass http://127.0.0.1:3000; } } This works well locally. I wanted some opinions before trying this out on the live box (a 256 MB VPS). Further, should I use something like monit to monitor webrick for failure?

• Is .htaccess slowing down my dedicated server?

  - by David Robles

  First of all, I consider myself more a programmer than a servers guy. I have a website where I receive about 3,000 visits per day, which I think is a lot less than the max capacity for a dedicated server. However, I've noticed that the connection to the website is pretty slow, e.g., to load images, to connect to it via SSH, etc. I configured .httaccess recently to avoid hotlinking to images in my server (i.e. .jpg, .gif and .png), and I was wondering if that could be slowing down my website. This is the configuration that I have: # BEGIN WordPress <IfModule mod_rewrite.c> RewriteEngine On RewriteBase / RewriteEngine on RewriteCond %{HTTP_REFERER} !^$ RewriteCond %{HTTP_REFERER} !^http://www.mysite.com/.*$ [NC] RewriteCond %{HTTP_REFERER} !^http://www.mysite.com$ [NC] RewriteRule .*\.(jpg|jpeg|gif|png|bmp|swf)$ http://www.google.com/ [R,NC] RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule . /index.php [L] </IfModule> # END WordPress I found some code to do that in google, and I just copied to .htacces since I'm not an expert in apache. It works, but I don't know if that is the best way to do it. How can I see if that is the reason why the server is slow? Are there any tools to monitor it? What would you do guys? Thanks in advance!

• Why do fonts sometimes look "fat" on Mac OS X?

  - by jtimberman

  Sometimes when resuming from suspend, the fonts in Mac OS X look "fatter" than normal. Unfortunately right now I can't get my Macbook Pro to exhibit the "normal" behavior for comparison, it has been abnormal yesterday and today. If I can get screenshots of what I think is 'normal', I'll add them. "Fixing" this has been random. I use an external monitor, and sometimes unplugging it and plugging back in, or even turning it off and back on has worked. Sometimes with the display attached (or not) detecting displays works. Sometimes logging out or rebooting entirely is what it takes. Displays used: Macbook Pro 15" built-in display Dell 27" LCD (2009 model) Software where I see this happen, at least most noticably: Firefox (screenshots below) iTerm Things MacIrssi (screenshots below) I am using Mac OS X 10.5.8. "Abnormal" view from MacIrssi with Inconsolata 16 pt. image full size "Abnormal" view from Firefox. Finally got it to switch back, though after resuming from suspend its back to "fat" :-(. image full size And 'normal' in Firefox:

• Laptop battery holds charge, but won't charge any more.

  - by Jeff

  Ok, I'm sure I will need to replace either my battery or my AC adapter, but would rather not buy one if the other is the problem. My problem is. I have a Sager laptop that gets quite a bit of use. The charging has always been a little bit odd. If I was in the process of using it, it would charge just fine and stay On AC power. If I left it alone, however(power settings to ONLY turn off the monitor) in either Ubuntu or Windows 7 it decides that it didn't want to use AC power anymore and would just start draining the battery until it died. Now, suddenly, it won't charge at all. The capacity was great up to this point which happened in an instant. It will recognize the battery but won't see the AC power if plugged in while the battery is in. I can power up the laptop without the battery and it works fine. If I plug in the battery while powered up it will claim it's charging it, but it stays at the same percentage. If I unplug the power, it will switch over to Battery fine, but I have to power down and unplug the battery to get it back on AC power. I've had dying/dead batteries before but they typically won't hold a full charge anymore but it still winds up to 100% then drops quickly when unplugged. This seems more like a chip problem in the battery to me, but I'm not sure. Any ideas?

• Walkthrough/guide building aplication server for multi tenant web app [on hold]

  - by Khalid Adisendjaja

  The web app will detect a subdomain such as tenant1.app.com, tenant2.app.com, etc to identify tenant environment, each tenant environment will have a different database credential (port,db name,etc) but still connecting to the same database server. Each tenant should use app.com for their main domain, using their own domain is prohibitted. Each tenant will have their own rest api endpoint such as tenant1.app.com/api/v1/xxxx, tenant2.app.com/api/v1/xxxx, tenant3.app.com/api/v1/xxxx I've come to a simple solution by setting a wildcard subdomain (*.app.com) on webserver Apache/Nginx vhost configuration file. I have googled so many concept for building a multi-tenant app server but still don't understand how to really done it, what is the right way to do it and what is actually required to do this task. So I've come to this questions, Do I need a proxy server, dns masking, etc.. How to monitor each tenants activity What about server performance, load balancing, and scalability How to setup ssl certificate for each tenant what about application cache for each tenant Is it reliable to use the setup for production etc ... I have a very litte experience on server infrastructure, so I'm looking for a DIY walkthrough, step by step guide, or sophisticate solution ready to implemented for production

• Production monitoring for EC2 instances

  - by Janine

  I'm setting up my first production instance on EC2 and want to make sure I have all necessary monitoring in place. There are three different types of things I want to monitor: Is the instance running? EC2 instances can be terminated without warning if the underlying hardware fails, and as far as I know they aren't automatically restarted. So if not, start it back up. Is UNIX running properly? This is the usual stuff about CPU load, disk space, etc. Is the website responding? If not, restart it. I initially set up Nagios on a physical server outside the cloud, but it is really only helpful for item 2. It can tell me if the instance is gone or if the website is not responding, but as far as I can tell it can't execute any commands to fix the situation. My Googling on this subject has yielded a plethora of options - Cacti, Monit, God, Ganglia, and probably more I'm forgetting now. I don't have time to research them all. I am aware of Amazon's Cloudwatch but it doesn't seem to do anything that my Nagios installation doesn't already do. If you already have something like this in place, can you please share what has worked well for you?

• Screen Flickering: Hardware or Software?

  - by Wesley

  I have a Samsung N120 netbook (upgraded to 2GB DDR2 RAM) and there has been a screen flickering issue for some time now. However, I have not been able to accurately determine whether it is a software or hardware issue. Here are some of the symptoms: The flicker is white-colored and shows up as vertical lines. Flickering or not, there may be occasionally some random blue patterns (no image distortion) The screen tends to flicker more when the screen is not tilted back all the way. When tilting the screen back and forth, the screen will usually flicker. Some images on the screen may randomly distort without full-on flickering. The screen will flicker only on certain websites, but not on others. A certain part of a webpage may constantly be distorted randomly, even when scrolling. While flickering, the mouse will not move though I'm moving my finger along the touchpad. A connected external monitor does not have any problems. The flickering is completely random and does not seem to follow any CPU/GPU usage trends. Flickering usually gets worse when the screen brightness is turned higher. There will be flickering on battery and while plugged in. Search up "Samsung N120 - Screen Flickering" on YouTube for an idea of what the flickering looks like. However, there is no visible distortions and the flickering seems to stop when the screen has dimmed. Since the problems started, I tried formatting and using Windows 7, then formatted again and went back to Windows XP. The screen was also replaced sometime during this past summer. The uninstallation of the Samsung Battery Manager (on the original install of XP) seemed to reduce the flicker partially, but eventually got worse. So, what could possibly be the problem?

• My Computer hangs for a few minutes just after startup, and then is fine.

  - by EvilChookie

  So I just built myself a reasonably beefy computer, and I installed Windows 7 on it. However, I start the machine up each morning and within a few minutes, the computer will semi hang. That is the mouse is responsive, and most of the time I can open task manager, or a new tab in Chrome. Occasionally windows will be labelled as 'Not responding'. Then, the machine will get over it's problem, and will be nice and quick until I turn it off. Here's my specs: CPU: AMD Phenom-II X4 955 Black (Quad Core, 3.2ghz) RAM: 4GB of DDR3 1300 MOBO: ASUS M4A785T-M (Latest BIOS) HARD DRIVES: 2x1TB Western Digital Caviar Blacks in RAID-0. OS: Windows 7 Ultimate x64. GPU: ASUS GT240 1GB. I believe this issue relates to the RAID array, as I didn't have the lockup problem before I created the array. I purchased a second drive and reformatted after creating a RAID array, since the single drive was a little on the pokey side (compared to the rest of the computer). What I have tried: Updated Raid Drivers Malware checks Windows Updates Unecessary Services CPU and Disk activity appears to be low (via Resource Monitor) No strange errors in the error log. Any thoughts?

• Windows 7 mapped drive kicking off OS X users

  - by Collin White

  I've mapped a network drive on my Windows 7 PC at my office. The windows machine has a few TB of storage that is being accessed by my development team (all running mac os 10.7). The share seems to work fine for a little while but will timeout and kick the mac users off and sometimes disallows a connection on the next attempt. Restarting the windows machine fixes the problem. I've tried this tutorial as well as setting the maximum session length in the Local Security Policy section to 99999 (I discovered 0 did not mean unlimited, only a 'reasonable ammount of time') anyway, the setting is now for ~208 days which is sufficient (see attached). I'm having trouble debugging this in general so if anyone has some pointers I'm all ears. This is a intermittent issue which in my opinion are the hardest kinds to debug. If anyone knows of how I might monitor connections from the PC that would also be pretty cool. Previously the files were hosted on a mac mini and everything was working just fine (the mini just didn't have the ability for the storage capacity we needed) so I believe it is some windows setting that is kicking users off. Anyway, thanks for reading.

• Compaq motherboard CQ60 AMD - nvidia chipsed graphic problem

  - by Dritan

  Hi! It nice to have read that you solved this problem this way. I have 2 laptops Compaq CQ60 AMD Athlon with Nvidia graphic cards. the first one is new, when i press power button, it lights up only the ON led in front and nothing else, no fan working, blank screen, no beep.. I don't know what may be the problem. When I put on power adaptor, it lights up only the side power led near dhe power adapter plug but it doesn't light up the front led one. the second one have this problem that it spins the fan, light power and On led, but it doesn't show nothing on the screen blank (even with external monitor). In this case it maybe this problem of the Nvida Graphic Chip and it may need a reflow. I have an hot air station, but I don't know if I should try this or the oven one. Please can you give me any suggestion what to do to solve this. I have read that the solution of the Oven method is just temporary,maximum of three months, do you have the same experience about this? Any suggestion is wellcome.

• Replacing compiz/metacity with openbox reduces workspaces to 1

  - by Brian

  I like to use the GNOME desktop, but I prefer to replace its window manager with openbox, with 4 workspaces. However, when I run openbox --replace, the number of workspaces available drops to 1. If I go into obconf, workspaces is still configured to be 4 (~/.config/openbox/rc.xml shows the same). I can get the workspaces to reappear by changing the value in obconf to anything else, and then back to 4. I have just been dealing with this problem since Ubuntu 9.04 (now up to 10.10) since I don't reboot very often. But it's really annoying to have to reset my workspaces whenever I do have to reboot. Changing the value in rc.xml and running openbox --reconfigure does not seem to have any effect. So what is obconf doing that I'm not (sends a dbus message perhaps [EDIT: watching with dbus-monitor I see no messages when changing the workspaces value in obconf])? I was hoping there would be a cleaner way to change the window manager than just running openbox --replace at login. So my questions are: Is there a better way to specify an alternate window manager (i.e. a way that doesn't cause the workspaces to break)? If not, how can I automatically set the number of workspaces back to 4? Update: I finally got around to trying what I commented on MrShunz's answer (adding WINDOW_MANAGER=/usr/bin/openbox to ~/.gnomerc). But the effect is the same as openbox --replace.

• Samsung laptop randomly shuts down

  - by Dmatig

  I've rewritten this question because it turned into an indecipherable mess. I have a Samsung R560 laptop that is overheating, and shutting itself down under load consistantly. Thank you quickcel for reccomending me Speedfan to monitor my temps. Here they are (Load / Idle): (Ignore "Temp1 and Temp2", whatever sensors they are they'd always random, pretty sure they're broke). The load temperature is after just 5 minites of playing Fallout 3 - another 5 minutes and it (the GPU - 9600M GS) consistantly breaches the mid 90's then shuts down, so it's hard to get a good picture of it. I'm looking for some solution or way to decrease these temperatures, because they seem far too high even idle. I've tried: Opening up the case and clearing of all dust with compressed air. Updating drivers for my Graphics card Have purchased and am using a notebook cooler I don't want to: Undervolt / underclock (defeats the point of having a more expensive card) Use lower power / performance settings (again, i might as well have bought something cheaper) Is there anything else i can try (software or inexpensive hardware) that can help me fix this? Has anybody had a Samsung laptop and knows if this can be sorted under my warranty, and the turnaround time of sending it off (UK?)(it has always ran hotter than it should, but now at 6 months old is getting hot enough to power off)

• MacBook Air i5 4 GB RAM shows screen tearing when scrolling in browsers

  - by Sandro Dzneladze

  I see screen tearing pretty often while scrolling webpages up and down, and it has been like this from day 1. But now I purchased an external monitor which is huge (23 inches compared to the Mac's 11), and the effect is more visible. It is driving me nuts and giving me headaches. I wonder if you see the same. I was reading a lot about this problem, and it seems to be present on MacBook Pros as well? Can someone confirm I'm not alone? In other words: I'm deciding weather to go through warranty repair, or if it makes no sense if all of theme exhibit same behavior. It is shame to see this beautiful machine with an insane price tag to be lagging when browsing web, when the processor is just sitting there idle at 4-12%! This is an example I found on Wikipedia that more or less describes what happens when I scroll up down. The effect is not so pronounced and clears when I stop scrolling, but it is sure annoying the hell out of me. Firefox is tearing like hell, Chrome less, Safari exhibits jagged scrolling but less tearing compared to Chrome and Firefox. With synthetic benchmarks I don't see any problems with hardware. But this is not particularly revealing.

• When machine is turned on, only the fan runs

  - by Gopal

  Hi, I have an issue slightly similar to this one posted here, http://superuser.com/questions/127016/troubleshooting-monitor-never-turns-on-system-fans-running-dvd-rom-does-not-op My configuration is as follows: EPOX 9NPA+ Ultra motherboard AMD Athlon 64 CPU Corsair 2 x 1GB PC3200 DDR RAM 1 DVD RW drive and 1 CD ROM Drive SATA 250 GB Hard drive 400W Power supply EVGA 256MB graphics card I have had this configuration for about four years. Last month, I started having issues in starting the machine. It wouldn't start when I press the ON button in the front of the case. So I used to pull out the power cord and plug it back in and then switch on in the front, and it used to work fine. And then one fine day, when I plugged in the power cord at the back, even without switching on the power-on button at the front, I saw that the fan at the back was running. So I opened the system. Then I could see that all the fans inside were running. I replaced the power supply. No luck there. Then I replaced the CMOS battery. Again nothing improved. Even when I removed all the cards and memory, I still get one short beep. That's it. Any idea how to proceed on this? Anything else could be checked? I want to confirm if this is a motherboard failure, before proceeding to replace it.

• SQL Server becomes slow after restart

  - by Tobi DM

  I already posted this one on stackoverflow but someone gave me the hint to that I might have more luck on serverfault. We use SQL Server 2005 on an Windwos Server 2008. Ther Server has 48 GB RAM. SQL Server is configured to use 40 GB RAM. There is only one database hosted (About 70 GB). The only app beside SQL Server is our App-Server which connects the clients to the database. Now we encounter the following problem: After a restart of the server our the performance is great. The server grabs the 40 GB RAM wich it is allowed to and then runs fast as hell. But after about 4 weeks the system becomes slower and slower. The execution of statements (seen in the profiler) is raising slowly. But I cannot see that there is something going wrong on the server. CPU usage is at about 20% I/O also seems to be no Problem The process monitor does also not show that there are strange apps or something like that. Eventlog does also have no interessting messages No open transactions or blockings to see We do not use cursors in our app We tried already the following things without effect: Droped the cache by using the statements DBCC FreeProcCache DBCC FREESYSTEMCACHE('ALL') DBCC DropCleanbuffers Restarted the Appserver we are using. Restart the sql server service But nothing did help exept restarting the whole server. Any ideas?

• Radeon 6950 - Garbling of text and graphics in certain Windows only

  - by Greg

  This morning I noticed the text in Gmail (in Firefox 4) looked a little funny (kind of thin, maybe some color fringing). I went to work and thought it might be some ClearType issue or something with the way Direct way that FF4 draws to the screen. When I came back from work (I left the computer on), the problem was much worse - way beyond ClearType nit-picking. The text was barely readable. I opened Chrome and there was no such problem. It seems like only Windows that use hardware acceleration are garbled, and ones that use GDI are not. But, I fired up Dragon Age and didn't notice any problems (I only really looked at the main menu though). Here is a link to a screen shot that illustrates the problem. Notice how the Windows Live Mesh window is completely unreadable, the text in Firefox 4 (left) is pretty bad, while Chrome, the Windows Control Panel, and the task bar are perfectly fine. The fact that the problem shows up in screen shots and that it only happens in certain Windows makes me confident that the problem cannot be with the monitor or DVI cable. I am using the AMD Radeon drivers from 4/27/11. The card I have (MSI Frozr II) came with a slight overclock (810Mhz) out of the box, but it looks like when I'm on the Windows desktop it's not running at full clock (CCC reports 450Mhz). Still, I underclocked it to the stock reference clock (800Mhz) and it made no difference. The idle temperature according to Afterburner is 42-44 Celsius, which seems a tad high but not enough to cause a problem - it's cold to the touch if I open up the machine. What the heck could be causing this? The problem varies in intensity. As we speak I'm in Firefox and things look better than they did earlier - it'll probably get worse again soon. Radeon 6950 (MSI Frozr II), Seasonic X 560, Core i5 2500K at stock clockspeeds, 16GB RAM, Asus P8P67 M Pro

• Plone site randomly serving wrong content

  - by Chris Miller

  I have a Plone site that has begun to randomly serve up the wrong content. Any given content suddenly shows something else. Sometimes a JPEG loads a stylesheet instead or a stylesheet loads as a page or a page as an image. The images move around, some times our site logo shows a bullet, or one of the other site images. Fiddler shows the wrong content in the response, the apache logs show the content type of the incorrect file (so if the an image loads in place of a style sheet, apache shows that). We thought mod_proxy was the source of our grief, but we get the problem hitting Zope directly. I never get the wrong content using the Medusa Monitor to repeatedly hit the content. I do see ConflictErrors in the instance.log file, and they seem to be correlated to the problem, but not 100%. ZPublisher.Conflict ConflictError at \path\to\object: database conflict error (oid 0x3586, class BTrees._OIBTree.OIBTree, serial this txn started with blah, serial currently committed blah) (X conflicts (0 unresolved) since startup blah) I pulled that off the web, it's not from our logs, but it's the same message. This may be a red herring, it sounds like those messages are normal. We've updated to the 3.3.5, same problems. I'm at a loss. I'm wondering if there a good way to intercept what is being served? Secondly, is there a way to increase the verbosity of the access log to included the content-type? I've even seen the problem manifest in ZMI. It happens more often when we're authenticated. Sometimes it can take a thousand reloads to see the problem, other times it happens in different ways every time we reload. I believe we've seen this problem for a couple years, but it was very intermittent, a page would show the content of a GIF, then a reload later wouldn't happen for a long time. Now it's a huge problem.

• Time sync fails on Hyper-V VM, but succeeds when I log in as a domain user

  - by Richard Beier

  We have a Windows Server 2003 SP2 VM running on Hyper-V (Server 2008 R2 host). The VM has Hyper-V time synchronization enabled. I noticed that the time on the VM was fast by around 25 minutes. I saw the following in the event log: The time provider NtpClient is configured to acquire time from one or more time sources, however none of the sources are currently accessible. No attempt to contact a source will be made for 15 minutes. NtpClient has no source of accurate time. The time provider NtpClient cannot reach or is currently receiving invalid time data from ourdc.ourdomain.local (ntp.d|192.168.2.18:123-192.168.2.2:123). Time Provider NtpClient: No valid response has been received from domain controller ourdc.ourdomain.local after 8 attempts to contact it. This domain controller will be discarded as a time source and NtpClient will attempt to discover a new domain controller from which to synchronize. I had been logged in as a local user. (We have an old app that runs on this VM - it requires a user to be logged in at all times, and we use a non-domain user account for this.) When I logged in as a domain user, the clock almost immediately corrected itself. Running "w32tm /monitor" and "net time" as the domain user showed no errors, and indicated that our domain controller was the time source. Does anyone know what might cause this, and why logging in under a domain account fixes the problem? I'm wondering if the time will start to drift again. Thanks for your help, Richard

• Amazon AWS VPN how to open a port?

• Massive Memory Leaks?

  Hi, I seem to have huge memory leaks, which are confusing me. I'm running fusion 3.1 / Windows 7 on Snow Leopard. It's a clean install with all upgrades applied. I've given fusion 8GB on a 14GB machine. I've installed VS2008 & Eclipse in Windows 7. Nothing unusual. Inside Task Manager in Windows 7, my memory footprint stays reasonable, at <2GB. But in OSX, Activity Monitor shows the footprint of vmware-vmx to be much larger. It starts at 2 GB, which seems fine, but whenever I'm actually doing anything in Windows, vmware-vmx's footprint grows at a few MB per second. After 20 mins or so it's using ~10GB and everything grinds to a halt. Throughout this, Task Manager still says I'm only using 2GB. And whatever I do in windows seems to increase vmware-vmx's memory footprint. Even closing down an application seems to make it go up. So is this par for the course in fusion? I was previously using parallels 3 / Vista under Leopard, and it worked fine. I'd assumed my new fusion config would work better, but this makes it completely unusable. (And apparently I can't even ask tech support unless I buy a support package...) Any advice much appreciated. Thanks

• Windows Action Center notification icon says Backup in Progress when no backup is occurring

  - by allquixotic

  How can I get Windows Action Center's little flag in the notification area to stop saying "Backup In Progress" on Windows 8? It's driving me nuts. I disabled the Windows Backup service completely and turned off File Recovery. Nothing that I can tell is using any disk I/O whatsoever, by examining Task Manager's resource monitor. It's just a visual cue that seems totally wrong considering my disk is only using about 50 KB/s of sporadic writes for superfetch etc. This wouldn't be a problem for me, since I rely on the knowledge that the Backup service is disabled and there's no disk activity, but I am trying to support a more traditional user who relies on visual cues from the operating system and trusts them over low-level observations like "...but the Windows Backup service is disabled!" Therefore this user still thinks that the backup is going on, even after the service is disabled. Technically, I think this is a bug in Windows 8. It really should not be displaying "Backup in Progress" if ... you know ... a backup, is not, in progress. Which it isn't. Is there a workaround?

• Radeon 6950 - Garbling of text and graphics in certain Windows only

  - by Greg

  This morning I noticed the text in Gmail (in Firefox 4) looked a little funny (kind of thin, maybe some color fringing). I went to work and thought it might be some ClearType issue or something with the way Direct way that FF4 draws to the screen. When I came back from work (I left the computer on), the problem was much worse - way beyond ClearType nit-picking. The text was barely readable. I opened Chrome and there was no such problem. It seems like only Windows that use hardware acceleration are garbled, and ones that use GDI are not. But, I fired up Dragon Age and didn't notice any problems (I only really looked at the main menu though). Here is a link to a screen shot that illustrates the problem. Notice how the Windows Live Mesh window is completely unreadable, the text in Firefox 4 (left) is pretty bad, while Chrome, the Windows Control Panel, and the task bar are perfectly fine. The fact that the problem shows up in screen shots and that it only happens in certain Windows makes me confident that the problem cannot be with the monitor or DVI cable. I am using the AMD Radeon drivers from 4/27/11. The card I have (MSI Frozr II) came with a slight overclock (810Mhz) out of the box, but it looks like when I'm on the Windows desktop it's not running at full clock (CCC reports 450Mhz). Still, I underclocked it to the stock reference clock (800Mhz) and it made no difference. The idle temperature according to Afterburner is 42-44 Celsius, which seems a tad high but not enough to cause a problem - it's cold to the touch if I open up the machine. What the heck could be causing this? The problem varies in intensity. As we speak I'm in Firefox and things look better than they did earlier - it'll probably get worse again soon. Radeon 6950 (MSI Frozr II), Seasonic X 560, Core i5 2500K at stock clockspeeds, 16GB RAM, Asus P8P67 M Pro
