scrolling in Firefox causes Xorg-process to lag (S3 Savage driver)

[Jordi Puigsegur]

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:

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.

Thank you for taking the time to report this bug and helping to make Ubuntu better. Please attach your X server configuration file (/etc/X11/xorg.conf) and X server log file (/var/log/Xorg.0.log) to the bug report as individual uncompressed file attachments using the "Attachment:" box below. Could you please also try to run without any /etc/X11/xorg.conf and let Xorg autodetect your display and video card? Please also attach the /var/log/Xorg.0.log from this attempt. Thanks in advance.

I attached lspci -vvnn, xorg.0.log and xorg.conf.

The corresponding xorg.log

[Jordi Puigsegur (jordi-puigsegur)]

This is my current xorg.conf

[Jordi Puigsegur (jordi-puigsegur)]

And this is the Xorg.o.log file generated with the above xorg.conf

[Andreas Moog (ampelbein)]

Please add the relevant bit of 'lspci -vvnn' to your bug report.

[Jordi Puigsegur (jordi-puigsegur)]

And this is the Xorg.o.log file generated with no xorg.conf file
Screen works, but it still has the same bug. Keyboard is not recognized properly.

Hi, I've forwarded your bug upstream to Xorg for their assistance with this issue. Would you mind please subscribing to the upstream bug report in case they have questions or need you to test something? Then you can provide the info directly without me slowing down the process.

[Jordi Puigsegur (jordi-puigsegur)]

Ok. I've subscribed to the 17097 bug in freedesktop.org

Thanks for your cooperation and time.

A co-worker advised me to use vesa driver meanwhile the bug with the savage driver is solved.
What is the way to do this?
It seems that dkpg-reconfigure does not configure video driver anymore (it relies on autodetection) and displayconfig-gtk fails.
Is there any way to tell the xserver autodetection to skip the savage driver?
Are there other tools to configure xorg.conf or should i submit a bug for displayconfig-gtk?

Add in /etc/X11/xorg.conf in the section "device":

 driver "vesa"

That should do.

If displayconfig-gtk does not work, you should file a bug.

Hi Jordi,

This bug was reported against an earlier version of Ubuntu, can you
test if it still occurs on Lucid?

The machine on which this occurred is now dead (hard disk crash, too old to repair), so I cannot test it.

[Jeremy Sequoia (jeremyhu)]

Is this still an issue?
