• How do I fix a super slow MacBook?

  - by MakingScienceFictionFact

  I'm running a black MacBook 4.1. Intel Core 2 Duo @ 2.4 GHz, 2 GB RAM, 250 GB hard disk drive, bus speed is 800 MHz. It's about three years old in excellent shape externally. I treat this thing like a baby. It used to run awesome, but now it's super slow at everything. I get the spinning pizza of death constantly. It takes a long time to boot up or load any program, even Safari and iTunes. iPhoto is terribly slow. The Internet doesn't work properly and it reminds me of a buggy PC. I've formatted it and re-installed Mac OS X 10.6 (with all updates), and I've done the disk repairs process. As an iOS developer this is driving me crazy, but luckily I have an iMac to work on in the day which is fast. I'm ready to format it again, but that didn't work last time. After the last format, I copied back files from an external drive so maybe the offending files were hidden in there somewhere. Here are the hard disk drive and RAM specifications. It is upgrade-able to 4 GB of RAM. Hard disk drive: The Fujitsu Mobile MHY2250BH is a 250 GB, standard hard disk drive. Its burst transfer rate is 150 Mbyte/s. This is a 5400 RPM drive and comes with an 8 MB buffer. RAM: two sticks of 1 GB DDR2 SDRAM, speed: 667 MHz.

• LG LW20 Express won't boot after hdd replace

  - by Mika

  My old laptop (LG LW20 Express) got a hdd failure and I replaced the hdd. Now the laptop won't boot from cd or usb. I'm trying to install ubuntu on it. When I turn the laptop on it shows me the startup screen but when it should be the time to load operating system it just gives a black screen and starts over. This loop continues until I shut down the laptop. I created the usb boot drive following this guide https://help.ubuntu.com/community/Installation/FromUSBStick/ I used my boot cd to install ubuntu on this machine I'm using right now. So at least the cd should work. From the BIOS I can see that my newly installed hdd is recognized and put as a secondary master. Also the cd and removable media are in the boot list before hdd. The laptop runs pretty hot. The fan is at full speed pretty soon after the laptop is turned on. Earlier I suspected that it would have been the almost broken hdd that would have produced that heat but there obviously is something else also. Any ideas what to check?

• Timeout settings for Remote Desktop Sessions to lock

  - by atroon

  Our office uses a Windows 2003 server to provide access to an accounting application. Recently I was asked to increase the amount of time it takes for the session to lock itself and require the entry of the user's password to resume. That seems to be about ten minutes, at present. I am familiar with group policy and have tweaked those settings to scavenge sessions (and thereby licenses) from sessions that have been disconnected (by the user closing the mstsc.exe client or by a network issue). That's simple and straightforward. But I can't find anything in GP to allow a longer time period before the RDP client window goes black and then, when clicked upon, requires a username and password to resume the session. I must admit this would be nice personally as well, since most of my time is spent documenting the application and/or monitoring its database, so I usually have a window open to the terminal server along with the rest of the staff in the accounting center, but I interact with it very little. I usually enter my password 10-15 times per workday, but I'm pretty good at it by now. ;) So, can this timeout period be adjusted, or are we out of luck?

• Windows 7 boot problem on a Lenovo Thinkpad Z61m 9450HAG

  - by Matt Taylor

  I recently did a full upgrade of Windows 7 on my Thinkpad. Everything worked fine after up until the second reboot (the first reboot after some updates installed worked OK). At second reboot time the system would just black screen before the Windows logo appears. Disk/wireless/power/battery lights are all lit and the disk light is active (flickering). However, if I remove my battery and boot with just power it boots fine and quickly, and everything is OK. Any help on why this won't boot with battery plugged in is greatly appreciated. I need to take this battery out on the road/trains, etc. A little more detail on this story. The battery I had inserted when doing the (failed) boot was a long life battery. I have not tried inserting this battery when Windows is logged in. I have another (normal life) battery that I have charged up within Windows. It has just got to 100% and I am about to reboot with it in. I am using the Lenovo power manager to diagnose the battery - all seems OK. I will report back shortly as to the outcome. OK, so I chose the reboot option from within Windows, the machine seemed to shutdown okay, but then stalled. It didn't turn off completely and didn't reboot, but just sat, with the fan humming, somewhere in between! I had to hold the power button in for a few seconds until the fan stopped and then hit the power button again to boot the machine from fresh. One good thing, with this battery (the normal one) it booted into Windows 7 the first time with a battery! So, now I have rebooting issues. I have 3 errors in the event log: A timeout was reached (30000 milliseconds) while waiting for the lxdxCATSCustConnectService service to connect. The lxdxCATSCustConnectService service failed to start due to the following error: The service did not respond to the start or control request in a timely fashion. The following boot-start or system-start driver(s) failed to load: cdrom Any thoughts?

• Ubuntu 10.04 freezing and Ctrl + Alt + Backspace does nothing but music keeps playing

  - by Bryce Thomas

  I'm having intermittent problems where the screen will freeze in Ubuntu. I've tried using Ctrl + Alt + Backspace to restart the X-server, though this does nothing. When the freeze occurs, there's a small square of black dashes around the mouse pointer - maybe 1 inch in size. These dashes look a lot like a 2d barcode. The rest of the screen looks normal, but I can't move the mouse and none of the keyboard shortcuts work to do anything. However, music that I begin playing before the freeze continues to play, which seems to indicate it hasn't stalled up completely. I've noticed a similar freezing problem when I'm using Windows 7. That is, I see the same barcode like dashes around the mouse pointer when it freezes up. So I'm guessing it's either a driver or hardware problem. I thought if it was a hardware problem though, the whole computer might stop working (i.e. music would stop playing)? The video card I am using is an Nvidia, and I believe it's in the 7600 range. In Ubuntu I have the drivers for the card set to the latest available (proprietary). Ideally I'd like to be able to continue using the proprietary drivers. Is there any known issues with the drivers for this model graphics card, or has anyone experienced the same problem and knows how to fix it?

• How do I make wallpaper fit both monitors in dual monitor setup?

  - by Ben

  I am deploying some custom corporate wallpaper as part of a Windows 7 rollout. Some people will be using dual monitors, and the additional monitors may be either 4:3 or widescreen. I want to use the same wallpaper on both screens (i.e. 2 copies of the same wallpaper, not stretched across both.) If I set the background to "stretch", it uses the aspect ratio of the primary monitor to stretch the wallpaper on both monitors. So, for example, if I have a dual monitor setup using a 4:3 TFT as primary and my (widescreen) laptop LCD as secondary - the image shows on the laptop LCD in 4:3, with a black stripe down either side. I've only noticed this as an issue with my "custom" wallpaper. Both the default MS wallpaper and the built in Lenovo wallpaper don't seem to have this issue. Is this by using "trickery" such as using an image larger than the largest resolution you will have and centering it? (i.e. so you crop out part of the image.) Or can this be done "properly"? I don't want to use 3rd party software to do this, but would happily do a bit of Powershell scripting if this would solve the issue. Thanks in advance, Ben

• Monitor is flashing through camera but not in the naked eye

  - by odyodyodys

  Two monitors: Samsung T23C350 - Samsung 2243NW Lets call the first A and the other B. A is a LED monitor with a 2ms response time (in specs) with a native resolution of 1920*1080@60Hz B is an older not-led one with 5ms response in specs with a resolution of 1680*1050@60Hz In the attached images and video you'll see that A (on the LEFT) is flickering but this is not visible to the naked eye. I took some pictures and videos with a camera and a mobile phone. This is also happening to all digital camcorders I've tested. A has a setting response time with values normal, fast, fastest. No matter the setting, the effect is the same. A on the left and B on the right. You can see the flickering, although both are @60Hz A video where you can see both monitors. A is always the left monitor. Another video where you can see what my digital camera sees. Another thing is that I managed to get a picture where the left monitor is completely black whilst the right one is displaying fine. This proves that the monitor is continuously flashing. My question is: Is this normal behavior and what is causing it? Am I affected by this fast flickering? I am using this as my primary monitor and as a programmer I have to keep my eyes on it for hours.

• Blending Background for Polar Distortion in GIMP

  - by Chris S

  I followed a tutorial to perform a polar distortion on a panoramic image. The instructions are geared for Photoshop but seem to mostly apply to GIMP as well. The only thing I couldn't really figure out was how they were able to automatically fill in the area around the circle by "extending" the border of the circle. e.g. In GIMP, performing the polar distortion leaves a black white canvas around the circle, not the attractive blended background shown in the tutorial. Is there an easy way to implement this? The only way I found was to reserve half of the "square" as blank canvas and then manually copy the image's top row of pixels over this empty portion. Then, after the polar distortion, I crop out the extra area. Although this achieves the effect, it seems a bit awkward. How do you stretch selections? Ideally, I just want to select the top row and stretch it vertically until it fills in half of the canvas. Instead I had to manaully copy, paste, translate, etc.

• Colorizing your terminal and shell environment?

  - by Stefan Lasiewski

  I spend most of my time working in Unix environments and using Terminal emulators. I try to use color on the commandline, because color makes the output more useful and intuitive. What are some good ways to add color to my terminal environment? What tricks do you do? What pitfals have you encountered? Unfortunately, support for color is wildly variable depending on terminal type, OS, TERM setting, utility, buggy implementations, etc. Here's what I do currently, after alot of experimentation: I tend to set 'TERM=xterm-color', which is supported on most hosts (but not all). I work on a number of different hosts, different OS versions, etc. I'm trying to keep things simple and generic, if possible. Many OSs set things like 'dircolors' and by default, and I don't want to modify this everywhere. So I try to stick with the defaults. Instead tweak my Terminal's color configuration. Use color for some unix commands (ls, grep, less, vim) and the Bash prompt. These commands seem to the standard "ANSI escape sequences" I've managed to find some settings which are widely supported, and which don't print gobbledygook characters in older environments (even FreeBSD4!) (For the most part). From my .bash_profile ### Color support # The Terminal application typically does 'export TERM=term=color' # Some terminal types will print Black, White & underlined with these settings. OS=`uname -s` case "$OS" in "SunOS" ) # Solaris9 ls doesn't allow color, so use special characters instead. LS_OPTS='-F' ;; "Linux" ) # GNU tools supports colors! See dircolors to customize colors export LS_OPTS='--color=auto' # Color support using 'less -R' alias less='less --RAW-CONTROL-CHARS' alias ls='ls ${LS_OPTS} export GREP_OPTIONS="--color=auto" ;; "Darwin"|"FreeBSD") # Most FreeBSD & Apple Darwin supports colors # LS_OPTS="-G" export CLICOLOR=true alias less='less --RAW-CONTROL-CHARS' export GREP_OPTIONS="--color=auto" ;; esac

• What is the sysadmin's dream network printer? 6-8k pg/mo. Xerox, OkiData, Lexmark and HP are all fail

  - by Jacob

  How do I find out what printer brand and/or type doesn't suck? This information is hard to find and manufacturer's websites won't reveal any issues with certain printers. After 10 years of dealing with network shared printers, I can't say that I have been impressed with any of the printer brands I've seen. Brother's little laser MFPs have been close to ideal for low volume, but that is it, period. OkiData, Lexmark, HP, Xerox solid ink printers, they all sucked in one way or another. Currently I'm looking to replace a Xerox ColorQube 8570 because it fails to print on a regular basis. Sometimes it doesn't even boot VxWorks fully - it just hangs at 2% or whatever. I've used Xerox 8860MFPs and they sucked just as bad. I won't talk about ink jets here, that's most likely not what I'm looking for. We currently spend about $4k on paper and ink per year for this printer at up to 6-8k pages per month, letter, mostly black and white, low color usage. I want the printer to feed paper correctly, not crash and burn when a PDF isn't according to its taste (my favorite Xerox problem here) and with decent drivers for Windows and OS X. Print quality is not of the utmost importance but paper does get sent to customers.

• How to convert JPEG JFIF files to JPEG Exif format?

  - by tigrou

  I recently put the SD card of my camera in a Windows 7 PC and start browsing pictures on it. I noticed some were not aligned correctly and use rotate feature included in Windows Photo Viewer in order to view them as I wanted. What I didn't know is that when rotate feature is used, it also overwrite the picture when pressing next or previous button resulting in a possible loss of quality (which is in my opinion a bad idea, app should at least warn user of what will happened when using such a feature). After that, I re-inserted the SD card back in my camera and bad surprise happened : the rotated picture could not be previewed anymore. Instead, i got a black screen saying "Incompatible JPEG format". Other files (untouched) are still working ok. To try to understand what happened I opened a JPEG file from camera and one generated on windows 7 in a hex editor. Here is the difference : The camera JPEG files have a Exif tag in them (with 0xE1 in header). Other JPEG files (Windows 7) have first a JFIF tag in it, followed by a Exif tag (with 0xE0 in header). So if i understand it well, both are JPEG files, but using a different internal format. Here is my question : is it possible (using some tool) to convert JFIF files to Exif format ? I understand that original camera files have been reencoded and thus lose some quality (getting originals back is impossible). What i want know if convert them from JFIF back to Exif (without a second loss of quality if possible...)

• Privacy, VPN and routers

  - by user123189

  Ever since this ACTA push-up the things are starting to heat up around torrents and privacy. I am using Tribler now, but this is not secure enough for me. Not enough privacy. I've been using in the past a swedish VPN PPTP connection. What I observed is that, when the VPN connection was down, Internet traffic wasn't cut off, rather the downloads were continuing, this time with my real IP, wearing off my protection. 1st : How to enforce a VPN connection that will cut all traffic when down? That is, the moment the connection is down, all internet traffic should cease as if I'd pull the network plug out. 2nd: Is PPTP good enough or should I ask for SSTP or IKEV2 ? 3rd: Should I disable IPv6 ? Is VPN no longer private if I keep IPv6 active? I 'heard some stuff' about dual vpn routers to be able to improve privacy; but nothing more about how to configure one for such a task. 4th: Is there any kind of "black box" hardware equipment that can be used in hiding IP, encrypting traffic and so on ?

• 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?

• Have it fixed or buy a new one?

  - by Workshop Alex

  My dual-monitor system has just become a single-monitor system again when the older monitor decided it would be nice to just turn to black. It's a Samsung LCD monitor and is over three years old. Not sure if the warranty is still valid but I just wonder what option would me more efficient: 1) Have the monitor fixed for a small amount. 2) Buy a new monitor for a slightly bigger amount. When monitors were still expensive, I wouldn't doubt about this and would just have my monitor repaired. But prices are so low nowadays, (and repairs are expensive) that I wonder if it's worth the trouble... Of course, I'm in no hurry since I still have another monitor. It's just that I liked the dual-monitor setup. Solved! Just ordered a new monitor. A Samsumg Syncmaster T260HD 25,5". Much more than it would cost me if I just had my old one repaired but I noticed that this one has a build-in TV tuner, plus speakers. It's way more expensive than a repair, but it's worth the additional value it provides.

• How I can fix the "Display Driver has stopped responding and has recovered"?

  - by Vitor Rangel

  I'm using a GeForce GTX 580, with Windows 7 64-bit. The driver version of the GTX is 301.42. The problem happens after a few minutes, when I'm playing specifc games. It won't happen in all games - And I don't have any idea why these games doesn't work. The games that doesn't work: Battlefield 3, Civilization V, Sniper Elite V2. The games that work: Mass Effect 3, Crysis 2, Team Fortress 2, Left 4 Dead 2, Skyrim, L.A. Noire. As you can see, it's not a problem of "The games that demand more stop working". I've tryed updating the driver of the graphics-card, the bios of the motherboard, even formated my computer (It was needing it) and instaled every driver in the last version possible. This problem happens since I bought my graphics-card, 6 months ago. After a few minutes, from 10 to 20, the pixels in the monitor become strange, with random colors and effects, like it was broken. Then, everything goes black, and the message appears "Display Driver has stopped responding and has recovered". After that, I need to close the game and start again. I am not overclocking, and my temperature never goes higher than 70ºC.

• SVG doesn't work on subdomain - some browsers try to download rather than display

  - by John Catterfeld

  I have a site with a 'development' subdomain, which displays my SVG file exactly as intended. However when I copy it across to www, or any other subdomain (e.g. 'test') some browsers try to open the file in an external editor, therefore asking me to download the file rather than displaying it. For example: http://development.mysite.com/test.svg - works http://www.mysite.com/test.svg - doesn't work The SVG file: <?xml version="1.0" standalone="no"?> <!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN" "http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd"> <svg xmlns="http://www.w3.org/2000/svg" version="1.1"> <circle cx="100" cy="50" r="40" stroke="black" stroke-width="2" fill="red" /> </svg> This happens in Firefox, Chrome and Safari, however IE9 and above display the file as intended. It is a Windows hosting, and I have <mimeMap fileExtension=".svg" mimeType="image/svg+xml" /> in my web.config file My hunch is that there must be some setting on the server which I need my hosting company to make. Can anyone suggest what might cause this issue?

• GA 8KNXP Rev1.0: 4GB installed, only 3.5 recognized by BIOS

  - by hurikhan77

  I've installed 2x 1 GB and 4x 512 MB memory into my GA-8KNXP system which would sum up to 4GB. The specs from the manual say: Maximum memory support: 4GB. If all six slots are utilized, slot 5+6 may only equipped with single-sided RAM modules. And so I did. Anyway: The BIOS counts up to 3.5 GB and finishes there. Also my linux system reports only 3.5 GB of memory although 4 GB memory support is activated in the kernel. So I suppose this is a memory mapping issue or a hardware issue. I've tried removing only on of the 512 MB memory modules leaving 5 modules in place. But that just stopped the system from powering on correctly (screen stays black although fans and leds come to live). Dual Channel was detected and enabled so the system technically found all 6 modules. "dmidecode" in linux reports only memory in slots 1 to 4 and ignores slots 5+6, so it only detects 3 GB of memory. It also says the system would support up to 16 GB of memory with 4 GB modules per slot. I think technically the chipset should be able to offer and utilize the complete 4 GB memory range. Any clues what else I could check? Or do I have just to live with 0.5 GB wasted memory?

• Windows 7 BSOD on startup

  - by Cristy

  I got a BSOD today after getting home from 11 hours of work... It seems to work in SAFE MODE (sometimes, not always) The BSOD says: SYSTEM_SERVICE_EXCEPTION STOP: 0x0000003b WimFsf.sys - Address FFFFF88001A6B76B base at FFFFF88001A600000, DateStamp 4a5bc362. Sometimes it shows the welcome screen, shows the destkop for a few seconds and then BSODs Already did: unplugged all the USB devices reset the CMOS I haven't installed any new software recently. What should I do? EDIT: I've managed to get into safe mode and it seems to works fine. When I go into normal mode it shows the desktop then it freezes... Is it more likely to be a software or hardware problem? EDIT2: I've managed to get into normal mode by disabling all the non-microsoft services & startup programs. One more thing: When I shut down my PC, on the "Logging off" screen appear some artifacts. I don't think it's because of my graphics card cause I've opened Black OPS and it worked fine. It's so strange... It still BSODS on startup (but there a ~=10% that it will not), and when it doesn't BSOD's it works fine...

• Building vs buying a server for an academic lab [closed]

  I'm looking for advice on the classic build vs buy question. We need a new linux server to run Matlab computation on in our lab (academic). Matlab parallel computing toolbox licence allows up to 12 local workers so we are aiming at a 12 core server with 4GB memory per core (total of 48gb). The system will have an SSD for the OS and a raid-5 (4x2tb) for data. I looked around and found a (relatively) cheap vendor, Silicon Mechanics, that offers a system to our liking (specs below) for $6732. However, buying the components from newegg cost only $4464! The difference is $2268 which is 50% of the base cost. If buying from a company can be thought of as a sort of insurance, basically my premiums are of 50% of the base cost which to me sounds like a lot. Of course any downtime is bad, but the work is not "mission critical", i.e. if it takes a few days to fix it when it breaks its no the end of the world. If it takes weeks to months then its a problem. If it breaks 2-3 times in 3 years, not too bad. If it breaks every month not good. In term of build experience, I set up a linux cluster in grad school (from existing computers) and I build my home pcs but I never built a server before. The server components I'm thinking about: 1 x SUPERMICRO SYS-7046T-6F 4U Tower Server Barebone Dual LGA 1366 Intel 5520 DDR3 1333/1066/800 ($1,050) 12 x Kingston 4GB 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10600) ECC Unbuffered Server Memory ($420) 2 x Intel Xeon E5645 Westmere-EP 2.4GHz LGA 1366 80W Six-Core ($1,116) 4 x Seagate Constellation ES 2TB 7200 RPM SATA 6.0Gb/s 3.5" ($1,040) 1 x SAMSUNG Internal DVD Writer Black SATA ($20) 1 x Intel 520 Series 2.5" 180GB SATA III MLC SSD $300 1 x LSI LSI00281 PCI-Express 2.0 x8 MD2 Low profile SATA / SAS MegaRAID SAS 9260CV-4i Controller Card, $695

• Thecus N5200, disk has dropped out of RAID5

  - by Anders Ekdahl

  We have a Thecus 5200 NAS here at work with five WD Caviar Black 2TB disks in a RADI5 array. Yesterday, disk 4 dropped out of the array, and in the NAS web interface there's a warning about the RAID array being "degraded". When I go into Storage - Disks, disk 1 and 4 has a warning next to them. When I click on the warnings, this information about the disks are displayed: Tray Number 4 Model WD2001FASS-00W2B Power On Hours 2403 Hours Temperature Celsius 34 Reallocated Sector Count 66 Current Pending Sector 1447 Raw Read Error Rate 61 Seek Error Rate 0 Hardware ECC Recovered N/A Tray Number 1 Model WD2001FASS-00W2B Power On Hours 2403 Hours Temperature Celsius 32 Reallocated Sector Count 0 Current Pending Sector 1465 Raw Read Error Rate 0 Seek Error Rate 0 Hardware ECC Recovered N/A I'm not really an expert on either disks or RAID arrays. Does this indicate that the fourth disk is damaged, and needs to be replaced? And what about disk number one? It has a warning, but it's still in the array. Is it safe to add the fourth disk back into the array as a spare? I can't find any way to add it back as a it were before.

• Win2008: Boot from mirrored dynamic disk fails!

  - by Daniel Marschall

  Hello. I am using Windows Server 2008 R2 Datacenter and I got two 1.5TB S-ATA2 hard disks installed and I want to make a soft raid. (I do know the disadvantages of softraid vs. hardraid) I have following partitions on Disk 0: (1) Microsoft Reserved 100 MB (dynamic), created during setup (2) System Partition 100 GB (dynamic) (3) Data partition, 1.2TB (dynamic) I already mirrored these contents to Disk 1. Its contents are: (1) System partition mirror, 100 GB (dynamic) (2) Data partition, 1.2 TB mirror (dynamic) (3) Unusued 100 MB (dynamic) -- is from "MSR" of Disk 0, created during setup. Since data and system partition are mirrored, I expect that my system works if disk 0 would fail. But it doesn't. If I force booting on disk 0: Works (I get the 2 bootloader screen) If I force booting on disk 1 (F8 for BBS), nothing happens. I got a blank black screen with the blinking caret. I already made disk1/partition1 active with diskpart, but it still does not boot from this drive. Please help. Both partitions are in "MBR" partition style. They look equal, except the missing "MSR" partition at the partition beginning (which seems to be not relevant to booting). Regards Daniel Marschall

• How can I remotely display images on my computer?

  - by Jakob

  What I Have: A laptop booted with Ubuntu and a stationary computer dual-booted with Ubuntu and Vista, both connected through a wireless ad-hoc network. What I Want: I want a way to display images in fullscreen on my stationary, using my laptop as a "remote control". I want to be able to choose another picture at any time and have my stationary computer remain in fullscreen mode at all times. Preferably, I should also be able to display just an empty (black) screen. How can I arrange for this? What I Have Tried: I have tried simply SSH:ing into my stationary computer and opening the image files using an image viewer, but all of the ones that I have tried (Eye of Gnome, Mirage, Gwenview, and others) open a new window for every new image. I don't know how to force them into using a single instance. I have tried using the VLC remote control command line interface, but apart from seeming somewhat unreliable (exiting with segmentation faults at one point), it also displays some images with a green border and forces me to pause playback in order for the image to remain on screen. Bonus Question: In my final setup, I also need to play music through my stationary computer's speaker and have the ability to switch to another track at any point, like with the images. Preferably, I would like to control the images and the audio through the same interface. How can I best achieve this?

• (Mac Intel) HP PS driver prints in B&W from Adobe Reader after installing Cannon PS driver

  - by John B

  I have a unique problem that leaves me at a loss as to where to start troubleshooting. We have three Macs we use for graphics, two of which are PowerPC and one which is Intel. They are set up to print to an HP 5500dn, but occasionally this printer gets tied up with a massive print job, so I installed the PS driver (iR-PSv1.81MacOSX) for the Cannon C3200 Printer/copier on each of the machines. Both of the PowerPC Macs installed without issue, but the Intel Mac exhibits strange behavior: I've confirmed that while the Cannon driver is installed (whether or not the Cannon is set up for printing in print settings), the HP 5500dn will print in color from Safari, but only prints in black and white from Adobe Reader. The Cannon printer itself has not exhibited any strange behavior As soon as the Cannon driver is uninstalled, the HP 5500dn prints in color from Adobe Reader again. We run a network of Windows PCs, and the 'Mac room' mostly takes care of itself, so we don't have any experienced Mac administrators onsite. The Cannon is capable of Appletalk, but the PS driver seemed easier to work with (and Appletalk is currently disable on the Cannon. I'm not against using the Appletalk compatible drivers, but I would rather use the PS driver if at all possible - I don't want to open up the proverbial can of worms. If someone has any clues or suggestions that would help troubleshoot this problem, I would be grateful. I've already done some googling, but due to the obscure nature of this problem, I haven't been very successful.
