Thank you very much. System does now boot with radeon driver and direct rendering on.
Thus I have a good workaround. I did not check which of the two options "PreferredMode" Virtual did make the job. When you would like to have any additional tests or information I would be pleased to help you. Relevant xorg.conf part now looks like (i.e. no BusType odr DRI off option needed): Section "Device" Identifier "Radeon 9250 128MB" Driver "ati" EndSection Section "Monitor" Identifier "Standardbildschirm" Option "DPMS" HorizSync 28-80 VertRefresh 43-85 Option "PreferredMode" "1024x768" EndSection Section "Screen" Identifier "Default Screen" Device "Radeon 9250 128MB" Monitor "Standardbildschirm" DefaultDepth 24 SubSection "Display" Depth 24 Modes "1152x864" "1024x768" "800x600" "640x480" Virtual 1024 768 EndSubSection EndSection -- Freeze with ati driver during boot on 8.04 https://bugs.launchpad.net/bugs/214105 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
