Public bug reported:

Binary package hint: xorg

I've got an Asus Eee PC 1015PE. On Maverick version, my laptop was able to manage his own screen in 1024*600 and an additional (LCD TV or Acer 1714  or Prolite E2410HDS) in full resolution : 1368*768 or 1280*1024 or 1920*1080 depend on screen used.
Since i've installed Natty, high résolution is available in choices fulfilled by the Screen setup, but if i select more than 800*600 the additional display is not usable : lines broken on screen or screen in mosaic. 
As i have the two versions installed (10.10 & 11.04 in two distinct partitions), i ve got back testing in 10.10 version, and it works fine, so i'm sure that hardware failure is not responsable of this malfunction.
