Pointer looks and work fine on laptop but when I connect external monitor it appears there as a shaking, square shape. Videos are not showing either.
my laptop hp 2133: Graphic card: VIA Technologies, Inc. CN896/VN896/P4M900, Chrome 9 HC. System: Lubuntu 12.04
I think it is graphic problem but can't find drivers for my card and system.
I do have xserver-xorg-video-openchrome and disper installed.
I did not have that problem with Lubuntu 11.10.
My problem is a bit like : Mouse pointer strange problem but it was not solved so I decided to post my question.
