Comment 9 for bug 161029

Hi! I have some symptoms that may come from the same problem.
I work with intrepid ibex on the Fujitsu-Siemens Amilo A 1640 (SIS 760 chipset) and sometimes i can't scroll normally (is it like a refreshing problem?) when i read text on gedit or when i use firefox.This is terribly boring and hard to use.
I also have another problem : there is always (on the left of the screen) many white and black lines appearing anormally.
I'd like to show you a screenshot but this (as the scroll bug) doesn't appear on it.
As I' m french, I tried to find a solution on the ubuntu-fr forum (http://forum.ubuntu-fr.org/viewtopic.php?pid=2282723#p2282723) but nobody could help me.
I know that SIS chipsets are quite problematics but hope someone will resolve this.
I also must tell you something : - The battery of my motherboard is down.
                                                   - When i use a 7.10 live CD, there's absolutely no problem (i even could watch a movie)
I join some files and hope this will help fix the bug.
