I'm a little confused here. When the error appears in Intrepid, you aren't using the "vesa" driver are you?
Could you try doing the following? I want to see if this bug is a duplicate of the bug I've reported (Bug #272877). Basically, when the black/empty screen appears you try to get to a terminal by pressing Ctrl+Alt+F1, stopping GDM, then changing the driver to "vesa" in xorg.conf, and starting GDM again. Here's a more detailed description: You can change the driver to "vesa" by getting to a console by pressing Ctrl+Alt+F1 (do this when the black/empty screen appears). Then shut down GDM by typing: sudo /etc/init.d/gdm stop Then you edit the file /etc/X11/xorg.conf with for example 'nano' by typing: sudo nano /etc/X11/xorg.conf There should be a "Device"-section (if there isn't just copy the text from below into the file /etc/X11/xorg.conf) that looks like this (there might be more lines of text between "Section" and "EndSection", but mine just looks like this when using the Intrepid Alpha 6 Live CD): Section "Device" Identifier "Configured Video Device" EndSection In this section add a line with the text "Driver "vesa"". Doing so with the example above would make it look like this: Section "Device" Identifier "Configured Video Device" Driver "vesa" EndSection Save the file and exit nano. Now start GDM again by typing: sudo /etc/init.d/gdm start Any changes? -- Intrepid daily, X Server hangs on ATI Radeon 9200 SE RV280 https://bugs.launchpad.net/bugs/274290 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
