Title:
scrolling in Firefox causes Xorg-process to lag (S3 Savage driver)
Status in X.Org X server:
Invalid
Status in xserver-xorg-video-savage package in Ubuntu:
Invalid
Bug description:
In a new installation of Xubuntu hardy from alternate CD on an old
Toshiba Satellite Pro 4300 Series everything seems to work but when
using the scroll bar in Firefox the system becames unstable and must
be rebooted to recover.
The only change necessary for it to work was adding acpi=force at
Kernel boot up.
When this happen:
- The display is not correctly updated / refreshed
- The Xorg process consumes more CPU than normal (~30/40%)
- Everything related to graphical windows slows down, but terminals (opened
before) work correctly.
Here is some information about the system and configuration:

configuration: latency=248 maxlatency=255 mingnt=4
The xorg.conf file only has "Configured video device" and "Configured
Monitor", which I think is normal in Ubuntu 8.04
I think it detects correctly the card and loads the correct driver:
jordi@canigo:~$ lsmod | grep savage
savage 33920 2
drm 82452 3 savage
If you need more information, I'll provide it.
