No KDE desktop effects after migrating from opensuse 12.2 to 13.1

English Applications
#1

I migrated my lenovo T510i notebook from opensuse 12.2 to 13.1 and reinstalled the proprietary nvidia driver from the community repo.
Dektop effects were on and working in 12.2. They are also ticked on in 13.1. But when I log in I only see some distorted graphic for some seconds and then the normal desktop without effects.
Is this known already? Some fix available? I haven’t found something on the forum so far.

#2

If the nvidia driver is working, KDE’s desktop effect should work as well.

Probably there’s a problem with your nvidia installation.

Please install the package “Mesa-demo-x” and post the output of:

glxinfo | grep render

What nvidia and kernel packages do you have installed?

rpm -qa | egrep "(kernel|nvidia)"

Have you installed all updates already?
There was a problem in 12.3 and 13.1 that you might have to add your user to the “video” group for the nvidia driver to fully work.
See https://www.suse.com/releasenotes/x86_64/openSUSE/12.3/#idm47462154153376
This has been fixed by an update though, and thus should not be necessary if your system has all the latest packages.
Whether you are affected by this should be revealed by the first command above.

#3

Thanks for the quick response!
The list of installed kernel packages looks suspicious. It is definitely not my intention to have several kernel versions and flavours installed (except for latest desktop/xen).
Also the nvidia packages for G02 and G03 is strange. I will try to reduce this to what I really need.

P.S.: Yes, I installed all available online updates.

#4

You installed both the G02 and the G03 driver, That’s not going to work. Uninstall the packages marked in red, then install either the G02 packages or the G03 ones.

#5

You do only have those 2 kernel flavours.
The rest are the *-devel packages for compiling kernel modules yourself.
I think kernel-syms needs all of those.

But they should do no harm.

Also the nvidia packages for G02 and G03 is strange. I will try to reduce this to what I really need.

Yes, that’s most likely the reason for your problem.
But please remove all nvidia packages, and then install the 4 necessary G03 packages.
The packages do contain the same files, so if you just uninstall the G02 packages, some files from the G03 packages will be missing as well.
You need those 4:
nvidia-gfxG03-kmp-desktop, x11-video-nvidiaG03, nvidia-glG03, nvidia-computeG03
Btw, something like this should not be possible anymore by mistake in the next openSUSE version, because zypper has been changed to check for file conflicts in Factory recently, so it would warn when trying to install both the G02 and G03 driver then.

#6

Ok, after telinit 3 I uninstalled all nvidia packages. Then I reinstalled the 4 G03 packages and rebooted. I also had cleaned up all old kernel packages. Now the output is much easier to read (and my /boot partition has some room left for the next kernel update…):

Unfortunately it did not help. I found this suspicious error in /var/log/X.0.log. I’ll try to google this:

    47.907] (EE) Failed to load /usr/lib64/xorg/modules/libglamoregl.so: /usr/lib64/xorg/modules/libglamoregl.so: undefined symbol: _glapi_tls_Context

P.S.: seems to be unrelated and harmles (see https://bugzilla.novell.com/show_bug.cgi?id=812426)

#7

You could have done this in runlevel 5 as well… :wink:
No need to switch to text mode.

Unfortunately it did not help. I found this suspicious error in /var/log/X.0.log. I’ll try to google this:

This is normal if the nvidia driver is installed. The undefined symbol error comes from the fact that nvidia replaces Mesa’s libGL with its own incompatible version.
FYI, glamor is 2d hardware acceleration via OpenGL, but you don’t need that because the nvidia driver provides its own 2d acceleration anyway. (glamor is mostly used on intel and some ATI cards with the Open Source radeon driver AFAIK)

Have you tried with a new user already?

What are your settings in “Configure Desktop”->“Desktop Effects”->Advanced?
They should be set to “OpenGL 2.0” (or OpenGL 3.1) and “Raster”.

#8

I browsed the system settings for desktop effects and changed the composite type from XRender to OpenGL 3.1
Don’t ask why, pure luck? Anyways, now it works.
Thanks for the support!

P.S.:
Ah, didn’t see your last post, cool, so that would have fixed it, too. Although I have graphic system Native. Will try Raster now, too.
Regarding text mode: There were times when this was necessary. Good to know I can dump this old habit :slight_smile:

#9

Nowadays Raster is recommended especially in combination with OpenGL for performance reasons.
