My Ubuntu 12.04 asked for some update and after the update, I can not boot (purple screen). In recovery mode the error is: no screens found.
Unfortunately I do not know how to undo the update. The Xorg.0.log files says:
LoadModule: vbe ... VESA(0): V_BIOS adress 0xd00 out of range UnloadModule: vesa UnloadSubModule: int10 Unloading int10 UnloadSubModule: vbe Unloading vbe Screen found, but none have a usable configuration Fatal Server error: no screens found
I didn't tipped everthing, but I hope this helps.
I'm really glad, if someone can help me. Thank you very much, Jonas
