Update ... I installed ATI Catalyst 9-10(8.661) on a fresh install of Kubuntu 9.10 Karmic Release Candidate. The driver installed well but during the driver installation a xorg.conf has been created by the ATI Catalyst installer(because there was no xorg.conf file present in "/etc/X11" folder) and when i reboot i had no graphic so i reboot again and choose the recovery mode. I had to delete the xorg.conf file and create a new one again and configuring it with "aticonfig --initial -f" then reboot again to have it work correctly. When i finaly got in the desktop i had to reconfigure the screen resolution using "sudo amdcccle".
Note if i just reboot after that everything stays ok but if i shotdown my computer and restart it instead of just doing a reboot the problem shows up again and i have to reboot in recovery mode to do the same process. So to be short, the problem is the same i had with Kubuntu 9.10 Alpha 4 with the previous driver of ATI Catalyst. My guess is Kubuntu 9.10 does not use xorg.conf the same way the previous versions of Kubuntu were using it. The problem is the ATI driver NEEDS this file to be installed and configured correctly. However, the xorg.conf file seems to become corrupted or obselete after shotdown but seems to keep its integrity after a reboot. P.S. : The recovery mode of kernel 2.6.31-14 is buggy, sometimes it's unusable because it's showing strange rendomly placed messages when i using the arrows to move between the options. I'll check if there is a bug report for that. -- xorg.conf needs to be reconfigured at each reboot https://bugs.launchpad.net/bugs/429419 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
