Public bug reported: Binary package hint: xorg
On a Toshiba L505D laptop (with an ATI M880G [Mobility Radeon HD 4200]), running Maverick, when X starts, there is only a blank screen, and a cursor which consists of a flat multicolored line. This cursor can be moved, and ctrl-alt-f1 can be used to switch to a console. The console displays numerous "Failed to schedule ib" messages. This is with gdm and starting X manually with startx. Following the instructions at https://wiki.ubuntu.com/X/KernelModeSetting I disabled KSM, and now X works normally. Specifically, I created /etc/modprobe.d/radeon-kms.conf with the following contents: options radeon modeset=0 The only downside I can see is that the console now has an 80 column display on a widescreen monitor, but this is minor.
