I've just installed 12 new Dell Optiplex 960 computers with Dell 2009W monitors. They are identical hardware and OS installs. Some of them are exhibiting a weird problem with their screens: They boot up and run just fine, but then the monitor goes black for 2 or 3 seconds, and comes back, with the small DVI icon popping up in the upper left corner to show which video connection is active. This repeats at random intervals continously; sometimes just a few seconds between, and sometimes many minutes.
The problem initially happened on just one machine so I had Dell swap the motherboard thinking it was a hardware issue. That did not fix it. Soon after that, I got reports from several users of the same problem on other of the new machines.
I've done a very basic install of CentOS 5.5, skipping all of my local configuration management stuff, and it still happens. Then I installed Ubuntu 10.04 and over the last few hours the machine has been rock solid. No video issues at all.
I have a brand new OptiPlex 780 from Dell, I downloaded CentoOS x86_64 from [URL]. The installer runs the graphics mode OK, when I reboot into normal, the graphics doesn't work.
The last messages I see are:
Red Hat nash version 5.1.19.6 starting starting clock, starting UDev
then the display goes away, the montior says "Not Support" The monitor is 1 day old and supports VGA to 1680x1050.
I try pressing "I" (and/or "i") when Red Hat first starts, but the interactive menu doesn't show.
I have two idenical machines, the other is running XP (the CentOS was also before I loaded CentOS), WinXP is allowing screen resolutions of
- 800 x 600 @ 60Hz, 72Hz, or 75Hz - 1024 x 768 @ 60Hz, 70Hz, or 75Hz - 1280 x 1024 @ 60Hz or 75Hz - 1680 x 1050 @ 60Hz ...all working on the same monitor.
During Bios boot, the monitor shows 600x800 @ 60Hz, during the text-only start of CentOS, it shows 720x400 70Hz. After CentOS boot shows starting udev, the montior breifly shows 720x400 70Hz, then "Not Support".
So.... Why isn't CentOS using the same graphics mode it used during installation (that worked fine)
I'm trying to run CentOS 5.4 (downloaded yesterday - CentOS-5.4-i386-bin-DVD.iso). Install process run well Pick default options on install. On partitioning part I've pick "Remove all partitions on selected drives and create default layout"
It get stusk after grub loading at : root (hd0,0) Filesystem type is ext2fs, partition type 0x83 Kernel /vmlinuz-2.6.18-164.el5 ro root=/dev/VolGroup00/logVol00 rhgb quiet [linux-bzImage, setup=0x1e00, size=0x1b3634] stops there, and not load the operating system

My next door neighbor has a dell Optiplex gx270 and wanted Ubuntu installing. Hardware: 1gb RAM P4 2.4 Intel 82865g Onboard Graphics. 40gb HDD
I tried the live cd and it froze on bootup, so I thought it might not be enough ram as the case sticker said 512mb ram. So I booted the minimum install cd and installed ubuntu desktop on it and then rebooted, when it boots i get grub and then screen will either do 1 of 2 things. 1. I get another flashing cursor in top left corner and then cursor stops flashing and then nothing happens at all. 2. Then screen will go black and nothing will show at all.
I have tried updating the BIOS, adding i915.modeset=0 to grub, didn't work either. Also couldn't find the xorg.conf under /etc/X11 to change driver to vesa. After several reboots atleast 30 since the check disk think showed and then it froze again. it booted correctly so I tried the latest intel driver from xorg edgers ppa. Rebooted and still the same thing happens. tried 2 different installs now and get same results. I have had to put winxp on it so he can atleast use it, but this will run out in 30 days unless he decides to buy it.
I have just bought a Dell Optiplex 960 with a NVIDIA Quadro NVS 450. Everything works out of the box with the 10.04.1 Live CD. It suggests to install and activate NVIDIA proprietary drivers, but you need to restart the machine afterwards.The problem is that, after that, all what you get is a blank screen, with not even a cursor.The same happens when you install Lucid: blank screen with no cursor.
Ctrl+F1 does not show anything, but Ctrl+Alt+Prnt Scrn+REISUB works and the PC is reset.In the var directory the logs show that the NVIDIA module is not loaded.
After installing a Dell Optilex 280 desktop with Centos 5.4, I configured sendamil, squid and all the extras I needed for a proxy and email server. All was fine until I switched the machine off. I had changed the resolution before and all was working fine. Now I have lost my gui , the system starts O.K but goes blank after "starting udev". I can use webmin to administer the server from a nother desktop/laptop but the monitor is totally blank. I tried most configurations on the /etc/X11/xorg.conf file even tried to create a new one using X -configure but still nothing changed. I cant afford to reinstall because of the time it takes to update the box, our broadband connections are so expensive this end of the world (Zimbabwe) and not so efficient. I have looked at the logs and tried to google but the solutions wont work for me? I suspect there could be an issue with the intel graphics adapter?
I have read all of the articles I could find on the problems. I am using the lilo bootloader as grub doesn't work. I have also added pci=nomsi to my lilo.conf and ran lilo -v. I can get the system to boot with kernel-2.6.18-8.el5. However I can't get the system to boot with kernel-2.6.18-194.11.3.el5.i686.rpm. When I boot with kernel-2.6.18-194.11.3.el5.i686 the system hangs after it prints bios data check successful. I tried adding suppress-boot-time-BIOS-data to my lilo.conf (I ran lilo -v after the change) and the system still hangs. The Optiplex 320 is running bios 1.1.12
Why won't newer kernels work? Is there a way to get more information to print before the hang to aid in debugging?
I no expert and this was a bit of mucking around. Installed Version 5 dot something on a desktop (DELL OptiPLex) with a couple of extra HDDs, for a server to play with (samba to Windows). I used the drives as a single logical drive via LVM.
We had a power cut, now it doesn't work. In fact it's been hanging around for a couple of years and before I dump it I wonder if there is any chance of getting some of the wife's letters, pictures, etc that I promised I try and get off.
The /boot partition seems to be there and I've attached a photo of what happens at boot, and I admit....I haven't a clue what it all means. Also I did not think ahead and did not create a recovery disk. I know, I know heap damnation on me for being so reckless, but any chance I can get myself back in the wife's good books?
I'm not sure this belongs in this forum as opposed to the hardware forum, but I do not beleive this is a hardware issue.I want to stop the scrren from blanking and going to power save. I'm running 5.3_x86-64 and I'm using the nVidia drivers direct from nVidia called NVIDIA-Linux-x86_64-96.43.13-pkg2.run.
So far, I'm added DPMS off in /etc/xorg.conf, removed all the screensaver packages and all the power management packagesbut the screen is still going blank after a time of inactivity.What else do I need to do? I can not allow the screen to go blank, there should be no screensaver or power management and the machine should stay in a completely awake and ready-to-use state at all times.
I try install debian 6 on my dell gx 270, but on some step of instalation I have error. I try other computer, also dell gx 270 but same problem. I try change cd rom, hard disc, ram .... but problem is still here. Is some chipset or something from dell is problem? I try install firmware-6.0.1a-i386-netinst.iso and debian-6.0.1a-i386-kde-CD-1.iso
I have a Fedora 6 in DELL Optiplex 755. When I installed Fedora 8, I got the following error message:
"An unhandled exception has occurred. This is most likely a bug. Please save a copy of the detailed exception and file a bug report against anaconda at http://bugzilla.redhat.com"
This error message is from action of screen: "Installation requires partitioning of your hard drive. By default, a partitioning layout is chosen which is reasonable for most users. You can either choose to use this or create your own."
I chose: "Remove Linux partitions on selected drives and create default layout" or
I chose other options, but I still got same error message.
Then I switched to a new HHD, but I still got the same error message.
I have learned something that I wanted to share with everyone. I don't know if this has been posted before. I was using a Dell optiplex 270 with a penium 4 processor 3 ghz computer 4g RAM dual processor. I tried to put the new Ubuntu on it because everyone was raving about it. Everytime I put the 10.04 on it, it slowed down and became very sluggish. I then had to reformat it back to 9.10.
I had an extra computer here that I was not using. It was also a Dell but it was an Inspiron 530 with an Intel Celeron CPU 2 ghz and 2g RAM. Well, to my suprise, it works GREAT with Ubuntu 10.04. I have not had one issue with it since I installed the new Ubuntu. In my opinion, it is a processor issue. I don't think that Ubuntu 10.04 works with a Penium 4 processor. It does work GREAT with a Celeron CPU processor.
It has been my understanding that Ubuntu (Linux) was made and has been made for older and new computers. It does seem that the new releases have been made only for the newer computers. Has anyone ever had these types of issues or come to these types of conclusions?
i have installed windows as well as linux on my system(dell optiplex 760).i m trying to install lan card drivers but the following error occur."Error resolving dependencies "unable to resolve the dependencies for some packages selected for instalation.
I recently switched my computer over to Fedora 12 from Win7. When I booted off the Live CD everything worked great, but after I installed and ran a yum update, I have no sound! The volume is not muted in any of the places I could find to look. I had the same problem in Ubuntu 10.04, which is why I decided to switch back to Fedora thinking I may not have the issue there ... but alas I was wrong. Here is some system info:

I'm trying to get WOL (Wake On Lan -suspend and hibernate don't work either) working in Ubuntu 10.10 amd64 on the above computer for a family member but seem to not be getting anywhere! WOL is enabled correctly I verified that after shutting down in windows XP that the computer came on with WOL. I have tried the following:
Enable wol Code: ethtool -s eth0 wol g
The computer shuts-down but won't wake up by WOL packet. Make sure the Ethernet (MAC0) can wake up PC Code: echo "MAC0" > /proc/acpi/wakeup The computer shuts-down but won't wake up by WOL packet
With all of the above, the computer doesn't not power down after shut down. The power button light is still on and has to be pressed to turn it off. Here is the strange thing: WOL works after manually tuning it off! I tried inserting apm module but it is not available.
I installed Ubuntu 10.10 32-bit on a Dell Optiplex GX240, it has an ATI Rage 128 Pro Ultra TF (from lspci output) and all the graphics run very slow (I'm assuming because OpenGL and hardware acceleration are disabled). I Googled the issue and found several solutions but non of them worked. I tried installing the ATI Catalyst driver but it doesn't recognize the graphics card. I also tried to install the fglrx drivers but when I run fglrxinfo I get a segmentation fault. So the X server is running with the open source (r128) drivers and it's really slow.
I'm a Dell Optiplex 380 MT Workstation user which have a Intel HDA Integrated sound controller. I was using Ubuntu 9.10 32 Bits Karmic, and all works fine, but, two days ago I did a fresh install to Ubuntu 10.4 LTS 32 Bits Lucid. In Ubuntu 9.10 I didn't do nothing to make work all features of my workstation, but, in 10.4 LTS the sound don't work. The hardware appear in "Speaker Icon" and in the alsamixer menu, but nothing works. It's happens in the Live CD, Installation in Hard Disc, 32 Bits Version and 64 Bits version.
Here is the output of the command, in Ubuntu 9.10 & Ubuntu 10.4. The only difference that I see is the follow in lspci (bold text): lspci Ubuntu 9.10: 00:1b.0 Audio device: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 01) Ubuntu 10.4: 00:1b.0 Audio device: Intel Corporation N10/ICH 7 Family High Definition Audio Controller (rev 01)
At both version this is the which use (same output): cat /proc/asound/card0/codec#0 Codec: Realtek ALC269
I've installed linux-backports-modules-alsa-2.6.32-21-generic-pae, reboot system and nothing happens. lsmod | grep snd Ubuntu 9.10 .....
I'm currently stuck at the "lubuntu - Install lubuntu" screen on a Dell Optiplex GX150 (specs; Pentium III 1 GHz, 512 mb RAM, 20 GB HDD). I can hear the CD spinning up but nothing happens. Looking at the specs, the PC should be able to run lubuntu, right? Could somebody point me in the right direction? I've verified both the ISO and the CD checksum, both check out, so there should be no issue with the install media
When attempting to install FC12 x86_64 on a Dell Optiplex 760, my USB devices stop working after initial boot. I see anaconda, but am unable to change anything since my keyboard, mouse and any other USB devices are not powering up after kernel boot.
I have disabled power management and un-installed gnome-screen-saver and themes. But the screen keeps going black, and it don't go into power-save. Exactly as if the screen-saver was present. Can it be xdg-utils ?
I have both Computer and Display set to NEVER SLEEP in power management. yet after about five minutes of inactivity, Ubuntu always blanks out the screen (i.e., just a black monitor screen but the monitor power light is still on).How do I stop this? I want to continue to see what is on my desktop--I do not want the screen to blank out ever.
10.04 32bit Desktop edition. I have unchecked the "Enable screensaver when the computer is idle" option and have set "put display to sleep when inactive for" to "Never" but the display is still blanking out!
I have removed gnome-screensaver, and to the best of my knowledge, it has not been replaced it with any other screensaver application.I have set System->Preferences->Power Management to never blank the screen. However, Ubuntu still blanks the screen if there has been no user interaction for a while.
The X server in Debian seems to have a "funny" habit to suddenly start blanking the screen if I don't touch the mouse or the keyboard for a while, although I've used the xset command (xset -dpms s off) in my ~/.xinitrc to tell Xorg specifically NOT to blank the screen. I know how to disable screen blanking in /etc/X11/xorg.conf, but I'd rather not have the xorg.conf file at all.
So, I'd be interested to hear your suggestions about how to disable the Xorg screen blanking without using the xset command or the xorg.conf file. Is there some other file in /etc/X11/ that I could tweak to disable this highly annoying desire of Xorg to insist on blanking my screen after a bit of idle time?
How do I stop the display from turning off? In 'System Settings/Screen', I can only choose from a preset range of minutes - there is no option to disable it. Very annoying when watching a 90 minute movie, for instance. At least under FC14 I had the disable option. I tried unchecking Power Manager in gnome-session-properties, but that disabled the system from suspending when the laptop lid is closed and might have other ramifications as well. I tried disabling Screensaver in gnome-session-properties, but 'System Settings/Screen' still showed up with the same options, so it appears to be unrelated. Anyway, I suspect this is a power management issue, not a screensaver issue.
I recently upgraded my 10.04 installation to 10.10 and ever since my dual monitor set-up has been behaving oddly - my secondary monitor randomly goes black for a second and then comes back as normal. I've tried to reproduce it with no luck and it isn't something I experienced with previous installations so wondered whether it's a known problem with 10.10? NVidia Quadro NVS 290
