• Ubuntu - No gnome-panels, no right-click, no internet, no hotkeys

  - by Darthfett

  Hey guys, I've been using Ubuntu (Maverick 10.10) on my desktop (ATI Radeon 5830) for about 3 weeks now, but all of a sudden I am unable to even use my computer. As soon as I start up, I see my desktop, with icons, but I don't see any gnome-panels, and I'm unable to get any options if I right-click. I can start programs by double clicking them. I also cannot get an internet connection. I've tried restarting gnome-panel by killing it, using Ctrl+Alt+5 to switch to a terminal (I don't have a shortcut to one on my desktop, and no hotkeys will work), but no luck. Restarting my computer has no effect upon this (I have to manually cut the power, since I don't know the terminal command). As far as I know, I have not made any changes, and I've never had any problems in the past. This started when I was playing Minecraft, but my internet crapped out, and no amount of re-trying the connection would work. I know it was my computer, as my brother's was working fine in the other room. Any clues as to what's going on? I'm more than willing to troubleshoot.

• Best usage for a laptop being used as a desktop without removable batteries

  - by Senseful

  After reading the information on http://batteryuniversity.com, I realize that one of the best ways to permanently damage a lithium ion battery is to use the battery at a high temperature while it's fully charged. This is exactly what happens when you use the computer as if it were a desktop computer, since leaving it plugged in will keep the battery at 100% and using the computer will heat up the battery. This is why it's recommend to remove the battery from your laptop if you are using it is this scenario. My question is what would you do if the laptop doesn't have removable batteries (e.g. a MacBook Pro)? Should I use some kind of charge cycle such as: charge to 80%, unplug the power chord, use the laptop until it reaches 20%, then repeat the cycle by charging to 80% again? If so, which values should I use instead of 80% and 20%? (I think charging to 80% is better than 100% because of the damage that a hot battery at 100% can do, but I just made the figure 80% up, and I'm sure there's a better number to strive for which is backed by science.) I've read many of the articles on batteryuniversity.com, but couldn't find anything pertaining to this. Update: What about doing something like charge (or discharge) it to 50%, then plug it in and turn on settings which use the battery as much as possible (e.g. brightness all the way up, wi-fi on, etc.), in order to try to maintain the battery at 50% (i.e. the rate it is charging is the same as it is discharging). This will probably heat up the battery, but would make it so you don't need to constantly plug and unplug the laptop. The one bad thing is that you are taking up more charge cycles which would decrease the battery life, thus I'm not sure this is a good idea.

• Has anyone else experienced page fault crashes with Snow Leopard on MacBook Pro?

  - by BruceMartin

  I bought a Macbook Pro computer on Sept 3rd from MacMall. As I was using it to learn Snow Leopard (this is my first Mac, I am a long time Windows developer), it would crash every one or two hours. After calling Apple support, I dropped it off at the Apple store for diagnostic testing and repair. WhenI picked up the computer from Apple, they told me that it did not crash while they had it. They suspected a software problem, so they had done a fresh install of Snow Leopard for me. At home I went through the start up procedure with the newly installed Snow Leopard. Then I downloaded the iPhone SDK, and the computer crashed again while I was away waiting for the download to finish. I was using a USB mouse, which was the only device attached. No other software installed. I was presented with a dump that mentions terms like "panic", Kernel trap", and "page fault". Does anyone have any idea what this problem might be? I really can not use this MacBook under these circumstances.

• Certificate enrollment request chain not trusted

  - by makerofthings7

  I am working on a MSFT lab for Direct Access, and need to create a Web certificate. The instructions ask be to do the following: On EDGE1, click Start, type mmc, and then press ENTER. Click Yes at the User Account Control prompt. Click File, and then click Add/Remove Snap-ins. Click Certificates, click Add, click Computer account, click Next, select Local computer, click Finish, and then click OK. In the console tree of the Certificates snap-in, open Certificates (Local Computer)\Personal\Certificates. Right-click Certificates, point to All Tasks, and then click Request New Certificate. Click Next twice. On the Request Certificates page, click Web Server, and then click More information is required to enroll for this certificate. On the Subject tab of the Certificate Properties dialog box, in Subject name, for Type, select Common Name. In Value, type edge1.contoso.com, and then click Add. Click OK, click Enroll, and then click Finish. In the details pane of the Certificates snap-in, verify that a new certificate with the name edge1.contoso.com was enrolled with Intended Purposes of Server Authentication. Right-click the certificate, and then click Properties. In Friendly Name, type IP-HTTPS Certificate, and then click OK. Close the console window. If you are prompted to save settings, click No. In production, our company has overridden the Web Server template and it doesn't seem to be issuing certificates with the full CA chain. When I look at the issued certificate properties then both tiers of the 2 tier CA hierarchy are missing. How can I fix this? I'm not sure where to look outside the GUI.

• Weirdly high ping on direct ethernet connection?

  - by Antriel

  I bought new Lenovo IdeaCentre H430 pc and I'm having problem with high pings. Windows 7 with on-board realtek NIC. Fresh install, fully updated, drivers installed from included CD. When I start pinging router (direct 1Gb ethernet connection, 1 hop), pings start at <1ms (which is fine) and after a while they jump to 300-1000ms. I loaded up live ubuntu to test if the problem might be in HW. It's not, in ubuntu pings were always <1ms. I also noticed that when I start using connection somehow, pings go down to 1ms, but go back up when I stop using it (tested by accessing live camera feed on LAN). Power Options set to max performance. I disabled Interrupt Moderation on the NIC, didn't help. I tested it in the safe mode with networking, same problem there. It slows down our client-server based programs and I have no idea what's causing it. All I could google up was that disabling Interrupt Moderation would help, it didn't though. Anyone had similar problems? tl;nr: Computer is giving high pings to router when idle and normal pings when network is under load, it slows down our software significantly.

• Everyone can access my Windows 7 Homegroup file shares - Even Windows XP computers.

  - by adriangrigore

  Hi, I have 3 computers in my network, two running Windows 7 and one running Windows XP. I've set up a homegroup on both Windows 7 computers. Also, all computers are in the same Workgroup. The problem is that one of the Windows 7 computers makes all shares accessible to the entire Workgroup instead of just sharing to the Homegroup as it should be. I created the file share in Windows 7 via right-click in the explorer, then click on "Share For" - "Homegroup (Read/Write)" (translated from German, so the actual wording may be different). Also, when I look at the file sharing properties of that folder, Windows Explorer informs me that Users must have a valid account and password for this Computer to access drive shares. Unfortunately this is not true. Being in the same Workgroup is enough to get access. Homegroup restrictions work as expected on my other Windows 7 computer. When trying to browse those shares from the XP computer, I get a dialog asking for a login and password. What might cause homegroup restrictions to fail and how can I fix this?

• MacBook Air Keeps dropping Wi-Fi

  - by Robert Patrick

  So my MacBook Air keeps dropping Wi-Fi for some reason. It happens ONLY on my home network, and ONLY to my computer. I'm using a Linksys WRT54G router. I'm the only Mac on the network. Every other Wi-Fi network is perfectly fine, and every other computer on this network is fine. Many things can happen. It could say it's connected, but not be able to access the internet (whether it tells me that there's no internet access or not). It may just drop Wi-Fi altogether, and refuse to connect. Generally, if I unplug the router and plug it back in, it's all good. It also works if I restart my computer. This happens multiple times a day. Yesterday I did everything I know to get it to connect (restart router many times, restart my MacBook), and nothing worked. Eventually it just magically worked. How can I stop this from happening? We got a notice from Comcast a while ago saying that a bot called DNS Changer was detected on one or more machines on the network. I'm assuming that this can't be me, right?

• Why we can change our IP address?

  - by iamstupid

  I across some websites that offer change of our IP addresses. It says, we can surf net anonymously, including changing our IP address and location. Most of the softwares are not free, so I have not try it out yet. But my question is, so, IP addresses will no longer be unique or valid for identify which computer were sending/request the information? I though only the ISP can determine our IP, so we can change our IP from some commercial softwares huh? Case: If I change my IP address, I go to a website which is supposed to be banned by my country, will the ISP let me pass the check and I will be able to browse the website which should be blocked? another question: From what I know, if we want to go to certain website, here is the flow: My Computer = ISP = Website = ISP = My computer I am not sure, if its the correct flow, but I am sure that, whichever website I want to visit, I need to go through my ISP, isnt it?. So if we change out IP, our ISP will record our new IP or the original(assigned-by-ISP) IP? Sorry for my bad English.

• Client unable to access OWA website after temporarily changing SSL certificate on the server

  - by Lorenz Meyer

  I have the following issue: One client computer (Windows XP) cannot access the OWA website. All other client computers can (Except another one in the same remote office). How this happened: I temporarily changed the SSL certificate on the Exchange Server yesterday. After a few minutes, I reverted back, an now the same certificate that was installed for years is back again. During these few minutes, they were in OWA on this computer and got a certificate error. What exactly happens: Internet Explorer displays the error Internet Explorer cannot display the webpage, Firefox displays The connection was reset and Crome shows This webpage is not available. The connection to ... was interrupted. What I already did to try to get this working: Restart the client computer Restart the exchange server Deleted Internet Explorer browsing history In IE, Internet Options, tab Content, under Certificates deletes SSL cache Restored Internet Explorer to the default parameters I looked into certmgr.msc, but did not find a certificate related to the issue What could I do else to narrow down the origin of this problem (or better: resolve it) ? Can you give any advice ?

• Self-connecting printers

  - by Martin Cerny

  Hello, I work as an administrator in a small company using XP Professional on all computers and two servers with Win 2003 Server. Recently a very unusual problam occured one of the computers keeps connecting to all the printers on the network it doesn't matter if it's an administrator or Domain User as soon as somebody logs in the commputer connects all the printers. The printers are either installed on local computers or on the server and shared. There is no log-on script connecting the printers, I install them manualy and none of the other computers shows such behaviour. We have a printer which is installed on two computers and both of them share it (I'm moving it to Server from a small PC which shared it up to now, but some computers still use the old connection), meaning this specific computer connects to one of the printer two times and it can't use either of the connections. How to prevent this self-connecting to all printers (none of the other computers has this problem). If I delte them from the "Printers" folder everything works fine untill I reconnect and the Folder is once again full of all the printers we have. I solved the smaller problem, computer is now capable of printing on all of the printers (it seems there have been some registry issues), after cleaning the registry and reinstalling the printer it seems to work just fine. But the second thing prevails, the computer connects to all the printers in the network (when I remove one/multiple it is reconnected right after the next log-in by any user).

• Lenovo System Update Breaks Windows Live

  - by wolfvilleian

  Hey everyone, I've been racking my brain (and fingers from typing) trying to solve this issue to no avail. I have a Lenovo computer and I install their system update tool to install all my missing drivers. However after this tool is installed Windows Live 2011 breaks, it will no longer sign in giving error number 8e5e0247 all the solutions online haven't helped. It appears that a language setting somewhere gets set to en_ms, and I'm en_ca. My computer is running Windows 7 x64. When i try to sign onto messenger it gives an error that (with some research) means your locale or language is not supported, I've searched my computer for any reference to en_ms but find none. Also a few other things seem to have broken, When a UAC box comes up it is no longer able to identify the publisher of anything, and also the indexing service does not work (I'm not sure if the indexing issue is related, but the UAC issue happened right after installation), I had this issue before but I don't remember how I fixed it, I believe it had something to do with environmental variables. When it goes to sign in it gets as far as the "Loading contacts" then stops and goes back to the sign in screen. Has anyone seen this before? Thanks

• Where is my problem? The P6X58D Premium Mobo, Windows 7, or other?

  - by Dylan Yaga

  I was having problems with my USB devices for an hour last night, and I am unable to determine the root cause of the problem. The two symptoms are: At seemingly random times (not consistently spaced by time or caused by any detectable event) my USB devices become "detached". Windows will play the USB disconnect sound and then the reconnect sound. The devices disconnected and then reconnected. My USB Keyboard will "stick" on one key for several seconds before processing any other keystroke made. The mouse also does not respond to clicks. I do not lose mouse movement or USB device connectivity. And after a moment of this several beeps will be emitted from the speakers. Hardware Specs: GFX Card: EVGA GeForce GTX 470 Superclocked 1280MB DDR5 PCIe Motherboard: ASUS P6X58D Premium Intel X58 Socket LGA1366 MB Processor: Intel Core i7-920 2.66Ghz 8M LGA1366 CPU Memory: Corsair Dominator 6144MB PC12800 DDR3 Storage: Hitachi 1TB Serial ATA HD 1600MHz 7200/32MB/SATA-3G Cooling: Corsair Hydro H50 CPU Liquid Cooler Case: Corsair Obsidian 800D Full Tower Case Power Supply: Corsair HX1000W 1000W Modular Power Supply Steps I have taken to narrow down the problem: Restarted the computer. - No change Changed USB port the Hub was connected to on the CPU. - No change Removed all devices from USB Hub and connected directly to CPU. - No change Used a different USB keyboard both in USB Hub and directly to CPU. - No change Disconnected and reconnected all cables. - No change Disassembled the Tower and determined if the USB headers were firmly connected. - No change Checked device manager for errors. Checked all USB devices. - Nothing flagged After an hour of frustration trying to narrow down the problem it appeared to disappear. But I am torn between it being a Mobo problem or an OS problem. Is there anything else I can do to narrow down the problem before a reformat and then eventually exchanging the Mobo?

• Vista won't boot. BSOD: Page fault in nonpaged area

  - by user31576

  Here's the story: I let Windows Update do the updates it wanted to do, then rebooted the computer. The updating process was taking time so I went away. When I came back, my computer was rebooting. It got as far as the Windows logo with the laoding bar. BSOD'd. Rebooted. And I'm stuck in this loop ever since. Looked up on the net, the "Page fault in nonpaged area" seems to be linked to faulty RAM or drivers. So I ran a memory test, it found no error. When I try in safe mode (with promt) I can see a list of drivers being loaded, then I get the same BSOD. I tried to repair using the Vista DVD, it says "nothing to repair". I tried to restore to a previous state, it says "no restore point found". So, my guess is, it's got something to do with the drivers. How can I identify the one causing the BSOD? If you have any other leads, What can I do? By the way, I'm writing from this very computer, running a linux distro I installed after the BSOD loop started. So i guess it's not an hardware issue. I have backed up important data, and will format and reinstall Windows if I must. But I'd like to avoid that. Thanks in advance for any help you can give me.

• Why is writing to my external hard drive slow, while benchmarks show fast writing?

  - by matix2267

  I have an iOmega eGo 320GB portable drive connected through USB2.0 to my laptop running Windows Vista. It's been working fine for quite some time until recently it became very slow when writing e.g. when copying ~300MB movie over to the drive at first it is extremely fast but it actually doesn't write it only puts in cache and then hangs on last 10-20MBs for about a minute. When copying larger files it's the same story: starts fast but then slows down to ~5MB/s (sometimes even slower down to 2MB/s). Strange thing is that I have always had caching disabled for this drive (it was disabled by default and I never bothered changing it). At first I thought that the disk is dying so I checked S.M.A.R.T. values and everything is fine there. I also run chkdsk and it seemed to fix the problem - it worked fast for a few minutes but then it slowed down again. I also tried plugging it into another USB port - no difference. Additionally I noticed that reading under certain circumstances is sometimes slower e.g. loading times for some games are ~10 times longer, whereas simple copying files from this drive to my internal HDD is fast. I ran a speed benchmark using CrystalDiskMark with a 5x100MB run and strangely got these results: read write (MB/s) Seq 33.05 28.25 512k 17.30 15.27 4k 0.267 0.372 4kQD32 0.510 0.260 This is different from what most other people have (I've found many threads about slow disk write while googling but all of them were slow on benchmarks too) which is why I decided to post this problem here. BTW most of the time when writing (or sometimes reading) the activity led is mostly idle (blinks a while and then stops for longer, sometimes has slower blinks ~1 sek, sometimes goes off for a few seconds - extremely long blink :) ) but when benchmarking, defragmenting or just reading (copying from this drive, installing apps from installers there, watching HD videos) it is blinking really fast (like it should) and there are no slowdowns. It shouldn't be driver issue unless stock Windows drivers have some issues I'm not aware of.

• How to restart boot Windows 7 after upgrading to a SSHD on SONY VAIO with recovery discs?

  - by Boris Okun

  The original HDD on my Sony VAIO still works, but has a damaged sector 0 and I was constantly prompted to replace the HDD because of the imminent failure. I created recovery discs as instructed, used a USB external HDD for complete back up (including Windows image back up). After installing the SSHD and using recovery discs to upload Windows and boot, I am getting the Windows welcome screen. Right after that, I'm getting the following message: Windows couldn't complete the installation. To install Windows on this computer, restart the installation. I have tried repeating the process many times all kinds of different ways and I still receive the same message. Also, when I tried to change to partitioning as the other option offered, I get the message: Windows Setup could not configure Windows to run on this computer's hardware. All troubleshooting for hardware and PCU came out solid. I tried to load the image back up from the external drive, but can't load the driver. The computer doesn't see it. Does anyone have a clue or has encountered something similar?

• Connect to WEP Wireless Network by command line on Ubuntu

• Windows 7 - All Icons Missing, Explorer Progress Bar Never Finishes, Libraries Gone

  - by Alex

  since yesterday i've had three issues which all arose at the same time. windows 7 x64, i7 2.8ghz 12gb ddr3 1 - my libraries, favorites, drives are missing...basically the entire sidebar is gone. http://i.imgur.com/m8pRQ.png. yet when i open a dialog, my libraries and drives are back to normal ONLY for the dialog. i tried Restore Default Libraries. it works one time, but when i open libraries again i go back to the empty mess. restarting the computer temporarily fixes the problem. 2 - in the explorer window that's showing libraries, when i navigate to a certain folder i get an unending progress bar (the kind that turns the address bar green). yesterday when the problem started, i was saving a file to this folder. the program writing the file crashed during the write and i believe that's what caused the problem. i have sugarsync backing up that folder and when i restarted the computer sugarsync informed me that its database was corrupted, so i had to uninstall and reinstall the software. 3 - icons are missing. the Rebuild Icon Cache did not fix this. http://i.imgur.com/r9pgo.png restarting the computer temporarily fixes these problems, but when i open the directory with the initial write problem, everything stops working. edit: i should note that i did a chkdsk /f and it repaired problems. i also did the thing that verifies then restores windows files (can't remember the command now), which reported that everything was normal.

• Fedora installed in Legacy mode, how to make it work in UEFI?

  - by TryntaLearn

  I am trying to install a linux distribution on my new laptop. It's an MSI GE40 which comes preinstalled with windows 8. It's a UEFI machine. I have tried installing Ubuntu and Fedora with limited success. I've tried: running it in UEFI, UEFI with CSM mode, with secureboot enabled, ... with secureboot disabeled, ... with secureboot enabled but in user mode. I have had no success with any of these methods. With Ubuntu the grub loader shows up, but when I pick 'try ubuntu', or 'install ubuntu', it's just a blank screen(I've been using liveusb's btw). With Fedora, it'll show me the next screen on which it says 'binary authorised by vendor certificate' or 'Secure boot not enabled' and then stop doing anything. The closest thing to success I reached was switching to legacy mode to install Ubuntu, in which case I was able to get to the ubunutu installer but it wouldn't recognize windows 8 on my computer, so instead of continuing on I rebooted, and removed the USB pendrive to find my computer couldn't find windows 8. After a little dicking about I got it to find windows 8 again. Any ideas on how I should go about trying to install a distro on my computer? UPDATE:- So I ended up installing fedora using Legacy mode. To use both it and Windows at boot, I manually enter automatic repair so I can get to my UEFI settings and switch boot mode to UEFI to boot windows 8. I guess my question needs to be modified as to how do I get all of this to work in UEFI mode, so I can dual boot via selection through a bootloader, and not by repeatedly switching boot mode.

• processes slow after some time of actively running

  - by Yervand Aghababyan

  i have several cron jobs running on an ubuntu machine. each one does some pretty heavy load stuff. The cron jobs are parsing files and the bigger the file the longer it takes them to parse it. The strange thing is that if i make the files too big ( like 30mb) the script kind of hangs. It starts processing them really enthusiastically but after some time (something like 5-10 minutes) the cpu usage of the process drops a lot and it gets into some "zombie" state. If prior to this the process in htop was using 70-80% of the CPU then after this drop occurs it slows down to something like 5-10%. the load average drops down as well. The status of the processes sometimes changes to D in htop, which AFAIR stands for zombie. Today i noticed the same behavior of processes of mysql when executing heavy queries (a query took something like 4 hours to execute). the cron jobs are mostly php and during their processing most of the CPU eats the php process and not mysql. so i think the issue is not with a specific language/program but with the way the processes are "managed". The only other place i've seen similar behavior was on my Amazon EC2 micro instance when after some aggressive use of CPU the CPU quota was taking effect and everything was slowing down dramatically. This is a dedicated machine running ubuntu. what may be the cause?

• Driver denied access to PCI card

  - by Corin

  Alright, I asked this on StackOverflow (here) and they suggested trying ServerFault to get help on permissions. So here's the deal. We designed a custom PCI card and wrote the driver for it. It's been working for years without problems but now we encountered one particular installation were it doesn't work. The problem is that we cannot connect to the PCI to begin communication with it. We tried replacing the card and had the same problem. We had the motherboard replaced thinking the PCI slots were bad. That didn't help either. We tried the cards in a different computer and they all worked. So it seemed to be something specific to the computer. The Windows Device Manager indicates the device is working properly and seems to have all the correct driver info. We now have this troublesome computer back at the office for testing. With the help of some extra debug info in the driver we determined that we cannot connect because access is denied. Sounds like a permissions issue to me. I should note that we are logged into the system as a local administrator. So what configuration option in Windows can prevent access to a device?

• File locked / read-only

  - by oshirowanen

  On a networked computer, I have a file which is coming up as read-only because someone else has it open. This is not true. This is a file stored locally on the computer and it is not being used by anyone else. I can login to the same computer using a different user, and the file opens up fine. I just get the issue with a particular user account. Other than deleting theses account/profile and creating it again, how can I unlock this file? Double clicking on this file gives me a message saying The file is locked for editing by another user, or the file (or the folder in which it is located,) is marked as read-only, or you specified that you wanted to open this file read-only. I don't think the folder is locked, because I can use other files in that folder fine, it's just 1 particular file which is causing this issue. I know that only 1 user is using this file as the file is on his c: and the same file works fine if he logs off to allow another user to log in.

• Site Goes Offline Every Day At Midnight - No One Knows Why

  - by HollerTrain

  0 down vote favorite Seems today a website I manage has been going online and offline between 12a and 12:25a. I have no idea what is causing the issue so I am seeking guidance on where to start. It is a Wordpress based site. So here is what I DO know: I have a pingdom account which alerts me when the site goes offline so we can see every day, like clockwork, the site goes on/off. At the time of the ups/downs I see a lot of strain on the memory usage. Look at the load average when the site is going online/offline (http://screencast.com/t/BRlfXkqrbJII). Then I ran this command to restart http (http://screencast.com/t/usVtYWZ2Qi) and the memory usage then goes down to this (http://screencast.com/t/VdTIy3bgZiQB). An hour after I restarted http, the site then went offline/online so restarting the http didn't do much help. When the site is going offline/online, I ran the top command and get this (http://screencast.com/t/zEwr7YQj3). Here is a top command when the site is at it's lowest (http://screencast.com/t/eaMfha9lbT - so this would be dubbged "normal"). Here is a bandwidth report (http://screencast.com/t/AS0h2CH1Gypq). The traffic doesn't seem to be that much (http://screencast.com/t/s7hrWNNic1K), but looking at my times the site is going up/down this may be one of the reasons? I have the dvp Nitro package at Media Temple (http://mediatemple.net/webhosting/nitro/). So at this point I would request some help in trying to figure out what the cause of this is, and how I can go about pinpointing this issue. ANY HELP is greatly appreciated.

• Work from home on an iPad?

  - by Alex Basson

  The situation: My wife has a 13" MacBook Pro that she uses for email, Facebook, web surfing, and working from home. I'm about to buy us our first iPad. My wife's brother's computer just went belly-up, and she's contemplating giving him her MacBook and just using the iPad. The question is whether or not this is possible or realistic. Obviously, the iPad is well-suited for the email/web/Facebook tasks, but the working-from-home thing is an absolute must -- if the iPad can't handle that, it's a deal-breaker. For my wife, working from home means two things: Accessing her workplace computer's Windows Vista desktop, which she currently does via Remote Desktop. Editing Office documents locally, which she currently syncs via Dropbox. Being able to edit documents locally is important, because sometimes she will download documents and edit them when she doesn't have network access (e.g. on the subway). I'm more than happy to get a keyboard dock for her, so typing won't be an issue. Are there any iPad apps she can use to access her work computer and edit her work files? Thanks for any suggestions!
