Thanks for finding that, I'm going to make this new and update the
title/description. Someone more familiar with SIS can pick this up if it
continues or more users sees this problem.
** Changed in: xserver-xorg-video-sis (Ubuntu)
Status: Incomplete => New
** Summary changed:
- Video corruption after 9.04 upgrade
+ [Jaunty upgrade] Video corruption when choosing 32MB of shared video RAM
** Description changed:
- I'm only a Ubuntu user. I'm not a specialist. I use Ubuntu since 6.06,
always accepting the upgrades for new versions, without any troubles, up to the
8.04. When I tried the upgrade to 8.10, most of pictures (images, photos,
films, the original wallpaper that apears the shadow of the monkey, etc.) was
"contaminated" by a lot of red micropoints, mainly at the lines of the details
of the picture (for instance, going around the monkey shadow).
- Two heavy users of Linux tried to help me without success.
- I've also tried the option of a new instalation of the sistem without
success. When I decided to reinstall the 8.04 the image troubles desapeared.
- I thought that with 9.04 the trouble should desapear but it has continued.
+ When I tried the upgrade to 8.10, most of pictures (images, photos,

+
+ After upgrading to 9.04, the bug came back.
+
+ I have 768 RAM memory. I decided to see these configurations in the
+ setup of the laptop. I could see that the video memory I could use 16,
+ 32 or 64MB and it was configurated to 32MB and I changed to the top,
+ 64MB and the graphic memory could use 32, 64 or 128MB and I did the
+ same, changed to the top, 128MB. After that, the problems desapeared.
+ The images became perfect.
