  • Not able to find scripts present in /etc/profile.d directory [on hold]

    - by priya
    I am using Red Hat Linux 6.0 ... using davinchi board. I have to change system clock resolution so I am changing (HZ) env var. For this I have written script so that I can change HZ = 1000 n insert that script in /etc/profile.d and write code for loop in /etc/profile so that while running as usual /etc/profile can load the scripts present in /etc/profile.d. But when I am logging into the system at root level then showing error as "-bash: ./etc/profile.d/resolution.sh(my script name): No such file or directory Also here why it is showing ./etc and not /etc . Is something related to that?? Also I tried to add script in /etc/init.d but still no change in value of HZ takes place. Please tell where to change so that this env var can get changed. The script(resolution.sh) written has :- #!/bin/bash export HZ=1000 The content of /etc/profile which I entered is: if [ -d /etc/profile.d ]; then for i in /etc/profile.d/*.sh; do if [ -r $i ]; then .$i fi done unset i fi And the output of grep command is -rw-r--r-- 1 root root 535 Feb 4 2004 profile -rwxr-xr-x 2 root root 4096 Feb 2 2004 profile.d

  • Expanding to dual video cards

    - by Anthony Greco
    I know a lot of factors can go into play here, so I will list my current hardware and setup: MOBO: GIGABYTE GA-890FXA-UD5 [http://www.newegg.com/Product/Product.aspx?Item=N82E16813128441] Processor: AMD Phenom II X6 1090T Black Edition Thuban 3.2GHz [http://www.newegg.com/Product/Product.aspx?Item=N82E16819103849] Ram: G.SKILL Ripjaws Series 16GB (4 x 4GB) [https://secure.newegg.com/NewMyAccount/OrderHistory.aspx?RandomID=4933910872745320111128011418] Current video card: EVGA 01G-P3-1366-TR GeForce GTX 460 SE [http://www.newegg.com/Product/Product.aspx?Item=N82E16814130591] OS: Windows 7 Ultimate x64 Currently I can run 2 monitors just fine in my setup. However, I want to upgrade this to 4 monitors. My question is, what is the best way to do this? I remember in the past reading I need the same type of video card, however would any GeForce GTX work, or do i need that very specific model (EVGA 01G-P3-1366-TR GeForce GTX 460 SE)? Are there any issues I should be aware of before I order 2 new monitors and a video card? Are there video cards better setup for this? I know NVidia offers SLI, however I do not know if my mobo is compliant. My mobo also offers CrossFireX configuration, though from what it says only Radeon are compliant. Any suggestions / feedbacks on my best route with my current setup is appreciated. Even if you suggest buying 2 new identical video cards, as long as you can mention which and why that is better I really appreciate it. Note: I really do not do any gaming. I sometimes do some 3D work in Unity and very rarely in Maya. Besides that I mostly do all my computer work in Visual Studios and Photoshop. I however need the 2 extra monitors because I monitor sometimes 5 remote desktops at once and switching on only 2 is becoming a very big pain. Also seeing 3 side by side while I work on the 4th will be very helpful. Again, I appreciate any feedback, as I have googled a bunch and just want to make sure what I buy will work.

  • Troubleshooting a Windows 7 PC that wouldn't sleep

    - by NPE
    I have a new Windows 7 PC that wouldn't sleep (not just automatically, but also when specifically told to). The screen goes black momentarily, but within two seconds the machine comes back as if nothing has happened. I tried powercfg energy. This produces some errors quoted at the bottom of this post, plus some warnings about timer resolution. There are no USB devices connected other than wireless keyboard + mouse (Logitech MK250); I tried unplugging them to no effect. The motherboard is Asus P7P55D-E. powercfg lastwake says "Wake History Count - 0", which I take to mean that it never actually went to sleep. I dual boot into Ubuntu, and was having exactly the same problem on the Linux side. That turned out to do with USB 3.0, which I've now disabled in the BIOS. This has solved the problem on the Ubuntu side of things, but made no difference to Windows 7. Any suggestions? Suspend:USB Device not Entering Suspend The USB device did not enter the Suspend state.

  • Firewall for internal networks

    - by Cylindric
    I have a virtualised infrastructure here, with separated networks (some physically, some just by VLAN) for iSCSI traffic, VMware management traffic, production traffic, etc. The recommendations are of course to not allow access from the LAN to the iSCSI network for example, for obvious security and performance reasons, and same between DMZ/LAN, etc. The problem I have is that in reality, some services do need access across the networks from time to time: System monitoring server needs to see the ESX hosts and the SAN for SNMP VSphere guest console access needs direct access to the ESX host the VM is running on VMware Converter wants access to the ESX host the VM will be created on The SAN email notification system wants access to our mail server Rather than wildly opening up the entire network, I'd like to place a firewall spanning these networks, so I can allow just the access required For example: SAN SMTP Server for email Management SAN for monitoring via SNMP Management ESX for monitoring via SNMP Target Server ESX for VMConverter Can someone recommend a free firewall that will allow this kind of thing without too much low-level tinkering of config files? I've used products such as IPcop before, and it seems to be possible to achieve this using that product if I re-purpose their ideas of "WAN", "WLAN" (the red/green/orange/blue interfaces), but was wondering if there were any other accepted products for this sort of thing. Thanks.

  • Converting An Older VMWare Image to ESXi

    - by Bart Silverstrim
    I have just installed VMWare ESXi and imported one physical machine without issue and one virtual machine, from an older version of VMWare Server on a Linux system, to it without issue. But I have another machine (Windows XP), virtual running on the VMWare Server, that I can't get the Converter to work with. Converter runs, says everything is fine, but when I go to the ESXi VSphere manager and hit the button to power up that vm, the console stays black with a blinking cursor and the processor for that VM spikes 100% and stays there. An event log item in VSphere warns something about activation issues with Windows. Has anyone else run into this issue before? Is it something with the disk controller? I copied the folder with the VM directly to the storage drive on ESXi hoping to create a new machine and point the data store to that folder or at least that drive image; nope, something about not using an IDE controller (must be something with the older format). In short, converter is doing something that particular machine doesn't like, and I can't find a way to simply open that hard disk image or convert it unless someone else has seen this. I try attaching a bootable CD image for disk repair to see if it can check the hard drive but I can't seem to get the console to boot from it...either too slow on the button or it just isn't able to easily boot from a virtual drive image (.iso). Any suggestions or help?

  • How to get automatic upgrades to work on Ubuntu Server?

  • Coffee spilled and went inside CPU...computer not starting

    - by Harpreet
    Today coffee got spilled over my table, and some of it (very less) reached the CPU placed under the table. I think little bit of it got inside the CPU through the front face of the CPU. As that happened the fan started running very fast and made noise. I tried to restart to see if it becomes fine, but the computer didn't start again. First it gave an error of "Alert! Air temperature sensor not detected" and didn't start. Next I tried again multiple times of starting the computer but then it gave some memory error. I was not able to start the computer. Incase there's a problem in hard disk or something related to memory, is there any way we can extract our work or data? I am scared if I am not able to extract my work in case some problem occurs like that. What options would I have? Help! EDIT: I have attached the photo here and you can see the area spilt in red circle. The hard drive electronics have been affected and internal speaker may also have been affected. Any advise on cleaning and if hard drive can work? EDIT 2: Are there any professional services offered to extract data from blemished hard disk, like this one, in case I am not able to run it personally?

  • How to fake ip at localhost without LoopBack.

    - by sexer
    How can i fake an ip on my own PC? for example if there were an ip address lets say 201.91.81.71, that Host is somewhere outside of my red and is hosting a webserver. How can set a website on my own PC, and when i go to browser and try to explore 201.91.81.71 it actually explore the website at my own PC? pd: I need it with IP addresses not domain names, since I need to implement it on a non-web service. First guess was installing a LoopBack with 201.191.81.71 as ip, but since some times the subnet works and some other it doesn't isn't a stable solution. Second guess was adding a route to route table : route add 201.91.81.71 mask 255.255.255.255 192.168.1.2 192.168.1.2 is the ip address of my NIC. If i could add this route it would work but windows doesn't let me do so. route add 201.91.81.71 mask 255.255.255.255 127.0.0.1 it doesn't let me set as gateway 127.0.0.1 if 201.91.81.71 isn't set in a NIC, so thats why i set sometimes loopback and this route add is auto, but it needs a subnet mask which doesn't match the ip and cannot set 255.255.255.255, im in real throubles here. can i get some help? thx.

  • Exchange MSExchangeIS Mailbox Store Error

    - by Bart Silverstrim
    Boss asked me to check to see if I could figure out why he's had to restart the services on the Exchange server three mornings in a row now. While going through the system logs I ran across an error from the MSExchangeIs Mailbox Store, category General, Event 9690. The message said (edited to make generalized): Exchange store 'First Storage Group\Mailbox Store (Servername)': The logical size of this database (the logical size equals the physical size of the .edb file and the .stm file minus the logical free space in each) is 22GB. This database size has exceeded the size limit of 22 GB. This database will be dismounted immediately. Hmm...happened at five in the morning, and I'm thinking this is a pretty good hint that this leads to the culprit. Thing is I'm not an Exchange expert, so I'm still googling around to figure out how to fix the problem. Any better guidance out there? Or am I barking up the wrong binary tree? Exchange System Manager reports that the server is "version 6.5 build 7638.2, SP2", standard, which I believe is Exchange 2003. It's running on Windows Server 2003 R2 Standard, SP2.

  • GA 8KNXP Rev1.0: 4 GB installed, only 3.5 GB 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 4 GB. The specification from the manual says: Maximum memory support: 4 GB. 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?

  • Internal/External Moodle - DNS

    - by Chief17
    Network diagram: I have a moodle (a VLE) setup that I want to be internally and externally accessible. The green route on the diagram below is the route I would like the traffic to take when the user is inside the LAN, and the red route is seemingly what it does take. The website has a domain name (like most websites do). From the User PC, if I ping the domain name, I get the internal IP of the webserver (because of a hosts file entry), if I nslookup the domain name I also get the internal IP of the webserver (because of an A record on my DNS server). Running the same two commands on the webserver gives me the webservers external IP. (going well so far) If I use PHPs gethostbyname() on the moodle website and use domain name as a parameter (getting php/apache to resolve the hostname) it returns the exernal IP of the webserver (good news, DNS seems to be doing what I want it to). All things so far seem to be going well. The only thing that is confusing me and preventing the moodle single sign on from working is the fact that if I get moodle to show my IP address, it says that it is an external one (outside my NATting firewall) when it should show an internal IP. This is the issue, any ideas on how to go about resolving this? Any ideas on tests I can perform (I have also tried a tracert and the request goes directly to the webserver), anything? Thanks all!

  • Windows XP Boot Issue - Diagnosing A Hard Drive Failure

    - by duffymo
    My five-year-old HP desktop running Windows XP SP3 wouldn't boot from the hard drive yesterday afternoon. I would see the boot sequence begin, then nothing but a black screen. Fortunately, I had just done an Acronis backup to my external drive in the morning, and I have a bootable USB key. I put the USB key into the drive, powered up the machine, and put the USB key first in line in the boot sequence. Voila! My machine came alive. But now I'm confused as to what the problem is and what to do next. I assumed that my hard drive was toast. But now that the machine is alive I can see files on my C: drive that have changes I made just yesterday. Clearly the drive is not dead. Here are my questions: What could explain my inability to boot from the hard drive? What would a remedy be? What's my best course of action? Should I replace the hard drive with a new one? If I replace the hard drive, do I reinstall the OS and apply the backup I did yesterday? If I decide that re-installing Windows XP makes no sense, how do I get back the Acronis backup that I did yesterday? I don't want to lose that. UPDATE: I just learned one more key fact. I'm having some work done on my house. I neglected to shut my machine down before the contractor came. My wife said he shut down the power to do some work on a circuit and then powered the house back up. I have a surge protector, but is it possible that cycling the power did some damage?

  • FFmpeg overlay two videos, one input with transparency

    - by Gian B.
    I am trying to create a karaoke from a CD+G file (converted to AVI using FFmpeg) and add a video as a background of the lyrics. Here's a screenshot of a the output from CD+G conversion, for simplicity let's call this lyrics.avi http://imgur.com/wUwHUhV Now a have this video.mp4 file that I'd like to put behind this lyrics.avi Here's a sample of what I'm trying to achieve http://imgur.com/8GuWXtQ I'm sure most of you are familiar with karaoke. I haven't used FFmpeg much and I'm not really sure if what I want to achieve is possible with FFmpeg. Is it possible to overlay two videos, and add a transparency to one of the videos? In this case the colour black? How can I set the offset time of the lyrics.avi? Here's the command the I've tried so far: ffmpeg -i video.mp4 -i lyrics.avi -filter_complex "nullsrc=size=854x480 [base]; [0:v] setpts=PTS-STARTPTS, scale=854x480 [upperleft]; [1:v] setpts=PTS-STARTPTS, scale=854x200 [bottomleft]; [base][upperleft] overlay=shortest=1 [tmp1]; [tmp1][bottomleft] overlay=shortest=1:y=280" -c:v libx264 -y karaoke.mp4

  • Laptop shuts down randomly without warning

    - by Robert P.
    My Asus Zenbook UX32V turns off randomly when I'm working on it. This happens both when the computer is recently turned on (5 minutes), and after being on for several days. I'm not running any heavy software The laptop is not heating The fan is not working on the maximum capacity (it's not heating) It happens when the laptop is lying still on the table It is no warning, it simply goes black It happens both when charging and on battery My guess is that it suddenly lose power somehow. What puzzles me is that I can flip the laptop upside down, sideways, shake it, etc. without it shutting off. This makes me think it's not something that's loose causing occasional short-circuits. I realize that the laptop probably doesn't like flipping and shaking, but it was the best way I could troubleshoot. I rarely turn the computer off, only have it in hibernate or sleep mode (most often hibernate). I've never experienced that the laptop is off when I wake it up from sleep mode. I've had the problem for a few months and it happens 2-8 times a week. Specs: Asus Zenbook UX32V Windows 8.1 (it happened in Windows 8.0 too) Intel i5-3317U CPU @ 1.70GHz The laptop is approx 1.5 years, but it has a small dent on one of the sides that probably voids the warranty. The dent has been there since week one and I don't think it's related to the problems I'm having now. Does anyone have a clue what might cause this, and how it might be fixed? I've read all other questions (some of which are listed below) that seem related to my issue, but none report the same behavior as I'm experiencing. Most report heavy games, heating etc. Asus N53J Laptop randomly shuts down Laptop is randomly shutting off Computer shuts down without warning My laptop acer aspire 5720 suddenly turn off randomly Computer randomly shutting down Windows 8.1 randomly shuts self down ASUS K55VM Laptop unexpectedly shuts down

  • Laptop Acer Travelmate 4050 takes over 10 Mins to POST

    - by Belliez
    Hi, I am a computer tech and have received a laptop for repair. I noticed when I turned it on the laptop would not do anything for a min or two (the fan would run up and stop, power led would shine and some cd rom activity then stop). It would sit there with a black screen. Suddenly after a random number of minutes (between 1-20mins!) the Acer BIOS screen would display and POST would happen before booting into Windows XP. It has frozen in XP at various times and pointed towards a CPU fault and over heating. The fan was on its last legs, sounded like a car engine, so I replaced this. Still same issues. I next replaced the CPU like for like. Same problems. Also applied new thermal paste between the cpu and heatsink, when running the fan kicks in occasionally (not as often as I thought it would) and I left it playing mp3, online radio and updating to service pack 3 and it wouldnt freeze. shutting down ok, cold start, not ok. Waits again before showing the BIOS screen. The hard disk was also making a screaming noise (SMART test and chkdsk passed) but I also replaced this. The laptop powers up with and without the battery so dont think its a battery issue. Running out of ideas and wondered if anyone had any advice. Thanks

  • Hardware issue: computer plays beep sounds at startup, and then turns off

    - by Darkkurama
    Turns out that after moving, my computer got damaged somehow. I installed my computer 2 days ago. I didn't check the state of the hardware parts and turned the pc on recklessly, not realizing that the cpu fan was dettached from the cpu. After this I reattached the fan. The computer worked kind of faulty after that, because at the time of startup, it would play a long beep (different from the normal beep) and won't display anything. I tried restarting after this incident and it got fixed (don't know how, but it did), and I was even able to play some videogames for some hours (more than 5). This morning I tried to get this issue sorted out by checking again the cpu and in general, the connections, and for my surprise, at the time of turning it on again, the computer wouldn't boot at all. I reapplied some thermal paste to the cpu and fan, but got no results (I did this because the old paste was very badly distributted along the surface of both cpu and fan). Now every time I turn it on, the computer acts randomly: sometimes at startup, it plays a long continous beep and then turns off. one time it played a long continous beep and got to the windows password input screen, but then it turned off More frequently, I turn it on and after some seconds, it turns off without any sound. You can check this video I recorded, which features how the computer behaves most of the time Another one I tried troubleshoting it myself by disconnecting my graphic card, rams, HDD and even the cpu and its fan with no result.

  • Symbolic Links Between User Accounts

    - by Pez Cuckow
    I have been using a cron job to duplicate a folder into another users account every day and someone suggested using symbolic links instead although I cannot get them to work. In summary user GAMER generates log files that they want to access via HTTP, however I only have a web-server in the user account SERVER, in the past I would copy the logs folder from GAMERS account into SERVER/public_html/. and then chmod the files so the server could access them. Trying to use symbolic links I set up a link from root (as only root can access both accounts) I used: ln -s /home/GAMER/game/logs/ /home/SERVER/public_html/logs However it seems that only root can use this link, I tried chmoding the link, all the files in the gamers /game/logs/*, /game/logs itself to 777 as well as changing chown and chgrp to server the files still cannot be read. When viewed from servers account my shell shows the link and where it is to hi-lighted in black with red text. Am I doing something wrong? Please enlighten me! /home/GAMER/game/ (chmod & chgrp) drwxrwxrwx 3 SERVER SERVER 4096 2011-01-07 15:46 logs /home/SERVER/public_html (chmod -h & chgrp -h) lrwxrwxrwx 1 server server 41 2011-01-07 19:53 logs -> /home/GAMER/game/logs/

  • HTTPS and Certification for dummies

    - by Poxy
    I had never used https on a site and now want to try it. I did some research, but not sure that I understood everything. Answers and corrections are greatly appreciated. Here we go: To use https I need to generate ‘private’ and ‘public’ keys for the web server I use. In my case it’s apache (manual: http://httpd.apache.org/docs/2.0/ssl/ssl_faq.html) Https protocol should be bind to port 443. Q: How to do it? Is it done by default? Where can I check configuration? Aplying https. Q: If I see https in browser does it mean that the data traffic on the page IS encrypted? Any form on the page would submit data via https? Though all the data gonna be encrypted, the browsers would still show ugly red messages. This is just because they do not know anything about my certificate. They have about a hundred certificates pre-installed but mine is not one of them, obviously. But the data IS encrypted by https. If I want browsers to recognize my certificate, I would need to have it signed by one of the certification authorities (ca) that has its certificate pre-installed (e.g. thawte, geotrust, rapidssl etc). UPD: To reed about ssl/tsl: The First Few Milliseconds of an HTTPS Connection, I found it very informative. Examples for PHP (openssl.org) of how to make use of ssl/tsl on the server side are published here.

  • Unable to access network resources through VPN

    I'm currently attempting to connect one of our computers in the office to a client VPN. My development machine is running Windows 7, and can connect and see resources just fine. The problem computer is running Windows XP. They're both within the same network. Using the same credentials at both computers, the VPN connection (using the built in Windows network connections) works just fine. So far, so good. An IP address is assigned, and comparing both machines shows they're still in the same subnet. The problem is that the XP machine cannot see ANY of the computers in the client network. I tried a tracert to a target machine on the Windows 7 box, and the first item that comes up is the .0 address. Pinging it gives responses. Trying it on the Windows XP machine, however, comes up with just timeouts. Trying to trace to www.google.com allows the address to resolve (probably part of the cached resolutions), but results in just timeouts. I double-checked to make sure that the Windows firewall was not on, and trying to open the settings brings up a notification that the firewall service wasn't running, which leads me to believe that it's definitely not on. From my best guess, I've managed to connect the XP machine to a black hole of some sort. There's obviously something strange going on, but I'm not sure where I should be looking.

  • How to grant read/write to specific user in any existent or future subdirectory of a given directory? [migrated]

    - by Samuel Rossille
    I'm a complete newbie in system administration and I'm doing this as a hobby. I host my own git repository on a VPS. Let's say my user is john. I'm using the ssh protocol to access my git repository, so my url is something like ssh://[email protected]/path/to/git/myrepo/. Root is the owner of everything that's under /path/to/git I'm attempting to give read/write access to john to everything which is under /path/to/git/myrepo I've tried both chmod and setfacl to control access, but both fail the same way: they apply rights recursively (with the right options) to all the current existing subdirectories of /path/to/git/myrepo, but as soon as a new directory is created, my user can not write in the new directory. I know that there are hooks in git that would allow me to reapply the rights after each commit, but I'm starting to think that i'm going the wrong way because this seems too complicated for a very basic purpose. Q: How should I setup my right to give rw access to john to anything under /path/to/git/myrepo and make it resilient to tree structure change ? Q2: If I should take a step back change the general approach, please tell me.

  • Turn off monitor (energy saving) while in text console mode (in Linux)

    - by Denilson Sá
    How to configure Linux text console to automatically turn of the monitor after some time? And by "text console" I mean that thing that you get on ctrl+alt+F[1-6], which is what you get whenever X11 is not running. And, no, I'm not using any framebuffer console (it's a plain, good and old 80x25 text-mode). Many years ago, I was using Slackware Linux, and it used to boot up in text-mode. Then you would manually run startx after the login. Anyway, the main login "screen" was the plain text-mode console, and I remember that the monitor used to turn off (energy saving mode, indicated by a blinking LED) after some time. Now I'm using Gentoo, and I have a similar setup. The machine boots up in text-mode, and only rarely I need to run startx. I say this because this is mostly my personal Linux server, and there is no need to keep X11 running all the time. (which means: I don't want to use GDM/KDM or any other graphical login screen) But now, in this Gentoo text-mode console, the screen goes black after a while, but the monitor does not enter any energy-saving mode (the LED is always lit). Yes, I've waited long enough to verify this. Thus, my question is: how can I configure my current system to behave like the old one? In other words, how to make the text console trigger energy-saving mode of the monitor? (maybe I should (cross-)post this question to http://unix.stackexchange.com/ )

  • How to crop Screen Recordings under Snow Leopard?

    - by willc2
    Quicktime Player for Snow Leopard now allows you record the screen. Awesome! Once you have a movie it will let you trim screen recordings for length. Is there a way to crop the movie's dimensions, either in QT or using some built-in or free software? Update: How to crop to an arbitrary size and aspect ratio? iMovie only seems to let you crop to the aspect ratio of the containing project. Result: Both good answers but since I have QuickTime Player 7 and Photoshop, that's the workflow I choose as the answer. NOTE: If you have Photoshop Extended, you can import a movie, use the crop tool, and Export the cropped movie. Not free or built-in, but convenient. To summarize the instructions from the video link ricbax posted: Open movie in QuickTime Player 7 Copy a frame and Paste it into a new document in Photoshop Draw a rectangular selection around the area to keep and fill with black Invert the selection and fill with white Save as .GIF, with 2 colors Back in QuickTime Player 7, open Movie Properties window Select the Video Track Select the Visual Settings Tab Drag and Drop the 2-color .GIF file onto the Mask drop area (or use choose file button) Export the (now cropped) movie DONE

  • How to fix Quicktime video color problems on nVidia chipset and Windows XP?

    - by Matthew Glidden
    My laptop frequently plays video as if in very low-color mode. Though the sound remains clear, it looks terrible, showing only a few shades of red, blue, or yellow. (It's even worse than 8-bit color.) The problem doesn't happen consistently, so I'm looking for troubleshooting advice or known solutions. I use a Dell Latitude D620 laptop with Windows XP, on-board nVidia video chipset, Quicktime, and multiple monitors (laptop screen + VGA-connected LCD). Color problems happen in each application I tried, iTunes, a browser, and the Quicktime standalone player. It doesn't happen right after reboot, so could be from a sleep-wake cycle, or at least being on for an extended period. Google results suggest reinstalling nVidia drivers, which I've done several times with no change. I have found 2 workarounds. Reboot, sacrificing significant time and disrupting work In nVidia control panel, change color to 16-bit, and then back to 32-bit This happens with all video playback, so it's definitely not one corrupt file. I use workaround #2 consistently, but would love a longer-term solution.
