Bug 338322 – kde-base/systemsettings-4.4.5 segfaults when opening Desktop settings group whilst using binary x11-drivers/ati-drivers-10.8

• Product: Gentoo Linux
• Status: RESOLVED NEEDINFO

[Description Tom Green 2010-09-22 01:19:36 UTC]

Every time I try to open the Desktop settings group in KDE's systemsettings util, I get a segfault.

If I switch to using the open radeon driver, the segfault goes away and I can open System Settings/Desktop every time:
emerge xf86-video-ati
edit xorg.conf, change driver to radeon
eselect opengl set xorg-x11
/etc/init.d/xdm restart
Log into KDE, open System Settings > Desktop, all good.

Reproducible: Always

Steps to Reproduce:
1.emerge ati-drivers, set driver to ati in xorg.conf
2.eselect set opengl ati, start X, log
3.Run KDE System Settings
4.Click the Desktop icon

Actual Results:  
The Desktop settings window flashes on-screen for a second, then disappears and the KDE Crash Handling assistant launches.

Expected Results:  
Desktop system settings window should show.

I have run revdep-rebuild twice, no reported problems.

I added FEATURES="splitdebug" and CFLAGS="-O2 -march=i686 -pipe -ggdb" in /etc/make.conf, re-emerged world

The KDE crash handler produced the below partial stack trace, which fails because of the binary ATI driver but which gave me the hint to try the OS radeon driver:
[to come, when I can edit this from the box in question and paste in.]
emerge --info
[to come, as above]

Other programs running: Dolphin, Konsole.
Computer: HP nw8440 notebook with Radeon M56P (Mobility X1600) graphics chipset.

I guess you mean "set driver to fglrx in xorg.conf" here. Can you try with ati-drivers-10.9-r1 to see if it makes any difference? It works here with that version (didn't remeber if i ever used it with 10.8). 

[Comment 4 Andreas K. Hüttel 2010-11-14 14:23:59 UTC]

an ati-drivers problem obviously...

[Comment 5 Enrico Tagliavini 2010-11-14 15:47:35 UTC]

Dunno to be honest. it is a veru strange problem. i used ati-drivers for about an year with various version of kde..... never had this problem

[Comment 6 Andreas K. Hüttel 2011-03-31 19:42:16 UTC]

Do you have any better luck with a more recent kde? I.e. 4.6.1 or 4.6.2 (out soon)?

[Comment 7 Andreas K. Hüttel 2011-05-09 20:44:01 UTC]

No reply, and kde-4.4 will go away soon...
