[Hinse ter Schuur]

Binary package hint: gnome-panel

Ubuntu 9.10 and ATI/AMD proprietary FGLRX driver (Radeon HD 3450 video card). Have dual-monitor setup.

After restart my right monitor doesn't display the correct contents, mouse cursor appears but noting more and the gnome-panel seems to have encountered a crash.
After I setted up my dual view again by using the System > Preferences > Display menu option al works correctly
