General :: GUI Not Working After Changing Resolution In Centos 5.4 On Dell Optiplex 280 / Fix It?
Mar 2, 2010
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 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'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.
Here is the output of lspci:

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 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 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 am having trouble changing the resolution in my Computer,I am new to Linux and somehow, Lucky, I got this program to install, I installed it on a Dell PowerEdge 1850 with a Radeon 7000 Video card,I had another one set-Up before which gave me a resolution of 1400 x xxxxx? Was great, this one only offers 800 x 600 and some other very low resolutions, The programing allows me to change it and demands I log out, Restart x and log in again, took me a day to figure out what was "x" and how to restart it, but no response. Still the same.
In reading the Forums I see this command allot "/sbin/lspci -m" But, too bad, nobody tells exactly where to type that series of digits to get any response,

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
Kernel parameters:
Code:
acpi=off
Code:
apm=power_off acpi=off
Code:
acpi=nopci
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

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.

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

I'm accessing a Red Hat Linux 5.5 machine with Gnome 2.16 and UltraVNC. I've started "vncserver" and am accessing my Linux desktop fine from my Windows machine. However, I can't change the resolution as I'm told: The X Server does not support the XRandR extension. Runtime resolution changes to the display size are not available.

I searched the archives and didn't find anything on this, and was just wondering if there is a problem if you load Ubuntu 9.1 and have a display that's higher than 1024x768. I'd prefer a machine with a higher res, but I've heard that Ubuntu will only go as high as 1024x768.I'm guessing, however, that by 9.1, it should recog the higher res while loading and it won't be a problem, but thought I'd check before shelling out on a machine with a nicer display.

I have a Dell Latitude C840 with a nVidia GeForce4 440 Go card and the screen is reported to go to 1600x1200, 32 bpp on Wikipedia. But I am unable to choose that resolution in Slackware. last time i changed the resolution to a higher one i needed to edit the xorg.conf, and change the HorizSync setting to match the monitor. but im unable to find the specifications on the screen for the C840. is there another way of doing this ? mabye a nVidia driver or something ?
Code:
# Monitor section
# Any number of monitor sections may be present
Section "Monitor"
Identifier "My Monitor"
# HorizSync is in kHz unless units are specified.
# HorizSync may be a comma separated list of discrete values, or a comma separated list of ranges of values.
# NOTE: THE VALUES HERE ARE EXAMPLES ONLY. REFER TO YOUR MONITOR'S USER MANUAL FOR THE CORRECT NUMBERS.
HorizSync 31.5 - 50.0
# HorizSync30-64 # multisync
# HorizSync31.5, 35.2 # multiple fixed sync frequencies
# HorizSync15-25, 30-50 # multiple ranges of sync frequencies
# VertRefresh is in Hz unless units are specified.
# VertRefresh may be a comma separated list of discrete values, or a comma separated list of ranges of values.
# NOTE: THE VALUES HERE ARE EXAMPLES ONLY. REFER TO YOUR MONITOR'S USER MANUAL FOR THE CORRECT NUMBERS.

I have made sure the card is not muted using kmix, alsamixer, and running alsaunmute 0. It was working for some time and just stopped. I am not sure if getting rdesktop to work on the laptop caused the issue or not since that seems to be the last major thing I did. (missing my sipie.py). This is what I am working with:

This week I picked up a Dell Studio Hybrid and installed CentOS on it. I originally used 5.0 since I already had the DVD and the network card wasn't recognized at all (lspci recognized it but the card didn't show up in system-config-network). I then downloaded the 5.2 DVD and installed that. The network card then showed up in system-config-network but it still didn't work. If DHCP is enabled it tells me that no link is present, and if I manually configure it, I still can't ping the router. lspci reports the following about the network card:
02:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 02)
The driver used is r8169.
I put Fedora 10 on it and the network is working fine, but I'd rather run CentOS on this machine. Is the issue likely to be fixed with CentOS 5.3 or should I just stick with Fedora?
