X fails to find ATI Radeon chip after upgrade to xserver-xorg-core-1:1.0.2-0ubuntu10.3

[Sascha Silbe]

Binary package hint: xserver-xorg-core

After upgrading xserver-xorg-core from 1:1.0.2-0ubuntu10.1 to 1:1.0.2-0ubuntu10.3, X won't start anymore. The errors logged in /var/log/Xorg.0.log are:

(EE) Failed to load /usr/lib/xorg/modules/extensions/libGLcore.so
(EE) Failed to load module "GLcore" (loader failed, 7)
(EE) No devices detected.

The graphics chip is an ATI Radeon Mobility U1 (PCI id 1002:4336).

I read other reports about similar in forums too
It helped to revert xserver-xorg-core to 1:1.0.2-0ubuntu10

[Chris (christian-fontana)]

it's happened also to me. I have a travelmate 290 with ATI MOBILITY RADEON 9700 chipset.

In my case the log ends with

(II) ATI: Candidate "Device" section "ATI Technologies, Inc. RV350 NP [Mobility
 Radeon 9600/9700 M10/M11]".
(EE) No devices detected.

Fatal server error:
no screens found

The attachment is the Xlog file.

I tested the upgrade on a VMWare VM and it worked fine.
I hope this can help your investigations.

Thanks
