I installed Ubuntu 6.06.1 LTS (Intel x86 desktop CD). During the livecd bringup it couldn't start X on my system, which is a Dell Dimension 9150 desktop. lspci etc. report the video card as "ATI Technologies, Inc. RV370 5B60 [Radeon X300 (PCIE)]" and the X autoconfig decided to the use the "ati" video card driver. I looked and it seemed that this was a "meta-driver" so this should work (?) To get X to come up I had to edit the /etc/X11/xorg.conf file and change the "Device" "Driver" entry to "vesa", which worked OK. After I had installed Ubuntu and updated I tried again with the "ati" driver but got the same result. I'll add xorg.conf and the X log file as attachments. After I got the system up I installed the ATI proprietary drivers (packaged for Ubuntu here: http://packages.freecontrib.org/ubuntu/plf) and tried out fglrx driver and that works correctly.
Created attachment 6650 [details] xorg.conf This xorg.conf is my working version: to get the failure I comment out (or delete) the "vesa" and "fglrx" lines and uncomment the "ati" line.
Created attachment 6651 [details] Xorg.0.log Log file from trying to start X with the "ati" driver.
Looking at the Xorg.0.log, this is the same bug as with my X800, ie bug 6976. Last lines are similarly "(WW) ATI: PCI Mach64 in slot 1:0:0 could not be detected!", and "(WW) ATI: PCI Mach64 in slot 1:0:1 could not be detected!" and "(EE) No devices detected.". *** This bug has been marked as a duplicate of 6796 ***
