Thanks for your input!

I tried that, last evening, to no avail. Did not matter which previous kernel I selected, the end result is the same.
Video goes to sleep after displaying the UDEV [OK] line. So, we know the video card is working.

Looking for any suggestions/advices as to where to look next.

Thanks,

Serge

Re-boot the system and as soon as you see the [i]grub[/i] splash screen, interrupt the boot process by pressing any key. Now select the [i]kernel-2.6.18-128.7.1.el5[/i] and boot it.

Does the display now operate correctly with the older kernel? If yes, then it is a kernel problem and a bug report would be appropriate. If no, then the problem is elsewhere.[/quote]

Have you tried booting to runlevel 3? If that works then try "system-config-display" as root.

Hi,

I found the problem at my side.

I use the propriatery ati driver and this cause the problem. I restore to the xorg server, driver from release 5.3 and restore also the xorg.conf. With this I can start x and after yum update all works well. After this I reinstall the ATI driver.

thanks for help

regards Dietmar

Hi Dietmar

Would you mind giving details of how you got xorg video restored? I don't know how to do it. Thanks

Not sure the way Dietmar did it would be the recommended approach, but sometimes "whatever works". Are you also using the ATI proprietary driver? Have you tried booting to runlevel 3 and running "system-config-display" as root?

Might want to have a look at http://wiki.centos.org/HowTos/ConfigureNewVideoCard

You really have a different situation - different hardware/driver. If the suggestions in post #16 don't help you should start a topic of your own.

My i915G failed to work after upgrading from 5.3 to 5.4, using the "intel" driver. The "i810" driver will work, but it's not the preferred driver for this chipset. I managed to get the intel driver working by disabling DDC in /etc/X11/xorg.conf:

Section "Device"
Identifier "Videocard0"
Driver "intel"
Option "DDC" "false"
EndSection

Update...

I booted at run level 3 after editing my boot file with Grub. I ran the following command: /sbinlspci -m

The following was what I found for my video controller:

00:02.0 "VGA compatible controller" "Intel corporation" "82915G/GV/910GL integrated graphics controller" -r 04 "Dell" "Unknown device 01C4"

So, next chance I have, I will try to figure out which driver to use from the command: rpm -qa xorg-x11-drv\*
It would be nice not having to make back flips to get this to work. Everything was working well until this latest update/upgrade.

Thanks,

Serge
