Qtcurve-->Configure Aqua Apply then Curve Apply causes plasma desktop crash RC2

Romanator · March 1, 2011, 1:09am

Qtcurve crashes kwin and a host of other programs when changing presets while using qtcurve.

KDE SC 4.6

I need more people to help out. Please install qtcurve and then try the following steps to confirm if this is on 32-bit and 64-bit.

**My Results with GeForce 8600 GTS
Driver: NVIDIA-Linux-x86_64-270.29.run
**
**Reproducible: Always **

**Steps to Reproduce: **

Select Configure Desktop → Application Appearance
Select Qtcurve -->Configure–> Aqua OK and Apply buttons
Select Qtcurve -->Configure–> Curve OK and Apply buttons
Plasma desktop crashes

Please see Bugzilla link:

I have tried, but cannot replicate this.

Three machines. Clean KDE installs of RC2.1 from the x86_64 DVD. Added qtcurve-kde, then followed your recipe. Then installed kernel-desktop-2.6.38-rc6 from Kernek:HEAD and repeated. Still no Plasma crash.

AMD 950e, 8GiB, integrated NVIDIA GeForce 8200
Intel Atom 330, 2GiB, integrated NVIDIA Ion
Intel SU4100, 4GiB, ATI Mobility Radeon HD4330 (this also has switchable Intel graphics, but I cannot get it to work)

There is no non-Free software on any of these installs – I am testing for work, not home use. Have you tried this without the proprietory graphics driver? Perhaps the problem is with NVIDIA rather than openSuSE or KDE?

Romanator · March 1, 2011, 4:51pm

Could be Nvidia. I’ll uninstall the Nvidia frivers and see what happens.

Lord_Emsworth · March 1, 2011, 4:59pm

You probably mean “Agua” and not “Aqua.” But still it totally crashes stuff.

Lord_Emsworth · March 1, 2011, 5:15pm

Sorry for the short reply, but my keyboard yielded up the ghost.

After changing to Agua and applying lots of processes crashed. Firefox was not one of them though.

Anyway:

KDE SC 4.6.0
openSUSE 11.3; 64-bit
QtCurve 1.8.4
GPU: NVIDIA GeForce 6100; onboard
Drivers: NVIDIA-Linux-x86_64-270.29.run

Romanator · March 1, 2011, 5:27pm

Thank you for replying. I thought I was seeing things. The problem also exists on openSUSE RC2.

You’re right the name is Agua not Aqua.

So, I uninstalled the Nvidia driver, set up Nouveau and I’m still getting about 55 windows pop up.
Various programs from akonadi to kwin to kdeinit to neponuk. And I’m running 64-bit.

I’m going to reinstall again. Any one else out there using an Nvidia card experiencing this bug?

Lord_Emsworth · March 1, 2011, 7:52pm

I am not sure this has anything got to do with Agua or QtCurve itself. I have meanwhile experience similar mis-behaviour when switching to other QtCurve configs, or totally different Styles, e.g. Plastique.

Lord_Emsworth · March 1, 2011, 8:02pm

I downgraded the NVIDIA drivers from 270.29 (installed the hard way) to NVIDIA 260.19.36 from the repositories. So that now my configuration is as follows:

KDE SC 4.6.0
openSUSE 11.3; 64-bit
QtCurve 1.8.4
GPU: NVIDIA GeForce 6100; onboard
Drivers: NVIDIA 260.19.36

It is the same story as it was before. Lots of crashes. But now I have collected crash-information, some of which is flagged as “may be useful” and some flagged as “is useful”.

I only have no real idea where to best put this info. :shame:

OK, done. I hope it is not too noobish.

That sound good.

Romanator · March 1, 2011, 11:06pm

Thank you for contributing. I welcome anyone out there with an Nvidia graphics card. If you are experiencing crashes with qtcurve presets to add to the Bugzilla report.

Hopefully, we’ll get a fix for this issue with qtcurve crashes when changing qtcurve presets.

If they can’t fix this major crash when changing QtCurve presets. I think the best thing to do is to remove the file(s) until this is resolved.

Any thoughts?

Romanator · March 4, 2011, 5:07pm

I gave added a bug report upstream with kde.org. This applies to Nvidia cards only.

https://bugs.kde.org/show_bug.cgi?id=267636

Hopefully, I’ll get some confirmation with them.

Btw If you just stick withe the QtCurve preset Agua, you won’t experience a crash. But if you switch…>:(

Romanator · March 4, 2011, 5:11pm

Since I’m getting 55 different kcrashes at once. How can I set up a trace the next time it crashes so all information can be written to a single text file.

Any thoughts?

Romanator

SeanMc98 · March 4, 2011, 9:15pm

This problem is not unique to Nvidia cards. I duplicated your crash(es) almost exactly on an i5-430m with Intel GMA HD graphics.

Confirm that the first switch (to Aqua) seems OK. The second switch starts a crash-and-burn (task after task) until the final swan song.

Just when I was dreaming of an Arrandale with switchable (Intel GMA + Nvidia) graphics!

Romanator · March 5, 2011, 3:46pm

I just got confirmation that the problem is not with the Nvidia cards (I’m running 64-bit) but the QtCurve style.

Refer to the bug report I submitted with kde:

https://bugs.kde.org/show_bug.cgi?id=267636

[LEFT][FONT=Bitstream Vera Sans]------- Comment #3 From Aaron J Seigo 2011-03-05 06:08:47 -------since all of those apps are crashing, that should be a hint that the bug is in the QtCurve style.[/LEFT]
[/FONT]

[LEFT][FONT=Bitstream Vera Sans]------- Comment #4 From Craig Drummond 2011-03-05 14:23:19 -------Totally agree - this is a bug in QtCurve. Versions < 1.8.4 had a bug where (for certain configurations) memory was beeing free’d twice. Sorry.[/LEFT]
[/FONT]
Hopefully, this will be fixed upstream and then passed on to our KDE openSUSE Team.

Romanator · March 5, 2011, 4:59pm

It’s official! This has been marked as “RESOLVED UPSTREAM” by the kde team.

Cheers!

Lord_Emsworth · March 5, 2011, 5:18pm

Thanks a lot, Romanator.

You are welcome. It sure pays to get involved.

Always try to submit bugs upstream with https://bugs.kde.org

and downstream with https://bugzilla.novell.com/index.cgi

Remember to have fun!
