Please attach the /var/log/Xorg.0.log file and the output of dmesg and glxinfo.

Comment 5 Michel Dänzer 2014-09-03 10:06:52 UTC

Does it also happen with

 Option "AccelMethod" "glamor"

in /etc/X11/xorg.conf? If yes, can you try a newer version of Mesa?

Comment 6 simon 2014-09-03 11:04:51 UTC

@Michel Dänzer

my xorg.conf is empty. if i add your lines the complete screen turns black the next time i login making kubuntu unusable.

not keen to mess arround with mesa drivers, as i have kde plasma next installed next to kde 4 and need kde4 for work.
or is this update available through the update center?

Sounds like you didn't create a valid xorg.conf. Something like this should work:

Section "Device"
        Identifier "default"
        Option "AccelMethod" "glamor"
EndSection


> or is this update available through the update center?

No idea, but there are PPAs.

"Something like this should work:"

and it did indeed. everything looks fine now.

Great, can you attach another Xorg.0.log corresponding to that?

@Michel Dänzer

the problem remains. in the meantime i have updated my kde plasma next via kubuntu ppa's like i  am doing everyday, and while the content in the xorg.conf remains the same, i now have the black screen again :(

next stop mesa drivers?
could you tell me what exactly do i have look for in the ppa's as this seems to be a custom install and not included in the updates.

Comment 13 simon 2014-09-04 07:16:57 UTC

@ Michel Dänzer

also the entry in the xorg.conf seems to be causing some graphical glitches in kde4 
see here:

Comment 14 Michel Dänzer 2014-09-04 07:23:47 UTC

So this is probably indeed a Mesa issue, and you can remove the xorg.conf file again.

Sorry, I can't help you with Ubuntu packages.

Comment 15 simon 2014-09-04 07:28:15 UTC

so where do i go from now?
kubuntu/KDE guys send me over to you to file the bug?

Comment 16 Michel Dänzer 2014-09-04 09:12:34 UTC

If you can create an apitrace demonstrating the problem, that should be useful.

Or if you could reproduce the crashes and attach gdb backtraces for them, that might also be interesting.

Comment 17 simon 2014-09-04 09:23:52 UTC

@Michel Dänzer

you won't believe it i just loged in kde plasma next again and the applet is now working again.
dunno what the problem really is.

i will leave it till tomorrow, do again a kde update and will have a look at it again.

i can reproduce the crash now sometimes.
basically i am playing arround with the various items in system settings, open close them, re open them, open a new one, etc. sometimes after 5, sometimes after 10 it crashes. and on some i have the infamous black screen.

Comment 19 Michel Dänzer 2014-09-05 08:53:20 UTC

Can you get another crash dump with debugging symbols for /usr/lib/x86_64-linux-gnu/dri/r600_dri.so ?
