Version: (using KDE 4.0.0) Installed from: SuSE RPMs Compiler: gcc version 4.2.1 (SUSE Linux) OS: Linux Hi. I am having issues with certain opengl accessibility desktop effects. Some of the 'desktop effects' either do nothing when activated or prevent me being able to click on anything / sometime even lock the machine so I have to restart X. Most 3D effects work fine - I can use the normal Magnifier, zoom, explosion fine (they work pretty fast on my nvidia card too!). However when I select the looking glass magnifier and press windows key and + it either crashes or does nothing - I have tried it both with the normal magnifier enabled and disabled - same result. Same thing happens with the sharpen desktop effect.. The strange thing the looking glass magnifer did work with one of the KDE4 release candidates.(think it was RC2.) I am having similar issues on the following systems (so doesn't seem hardware / distro related.) [my desktop] opensuse 10.3 64bit (xorg 7.3) - nvidia geforce 8500 - kde 4.0.1 gentoo 64bit - nvidia geforce 8500 - kde 4 (from masked portage) [my work desktop (they give us crap onboard video cards...)] opensuse 10.3 32bit (xorg 7.3) - intel 915G - kde 4.0.1 On both machines most 3d effects work (it is definitely in opengl mode not xrender) so I am sure all xcomposite settings are enabled.) Is there anything I can do to provide more info on this ? Thanks P.S - loving how KDE4 is coming on (as mentioned already using it at work...)
Please provide the backtrace from the crash and any possible error output.
Please can you guide me on how to provide a backtrace ? As the screen locks up I am unable to kde until I restart X I believe that you use gdb , can someone please point me in the right direction.
I also used to get this problem sometimes. I can confirm it is not crashing, it is outputting a GLError and not updating the screen. The GL Error is 0x502. Looking glass does work sometimes (normally the first time after starting kwin) but after that it produces this error. I am using nvidia 169.09 now and am finding it difficult to reproduce.
See http://techbase.kde.org/index.php?title=Development/Tutorials/Debugging and related pages for debugging howto. You can switch to text console and attach gdb to kwin to get a backtrace. You can also redirect kwin output to a file to get it.
Hi. I have tried to use gdb but I must be doing something incorrect. I am able to use it with opengl desktop effects disabled, however when I use gdb with opengl effects enabled it locks the system and I am unable to get to the konsole window, I have to go to a console window out of X and kill the gdb process. i.e : -------------------------------- kde4user@mrsuseamd64:~> ps aux | grep kwin kde4user 22668 1.7 4.0 262672 41248 pts/2 SL 12:13 0:27 kwin --replace kde4user 23180 0.0 0.0 5120 796 pts/3 R+ 12:39 0:00 grep kwin kde4user@mrsuseamd64:~> gdb kwin 22668 - the screen then locks until I kill gdb. Can someone please let me know what i'm doing wrong. Also if someone could explain how to make it write to a file then could be useful. Cheers.
I really would like to help give a backtrace. Can someone please give my the commands that they would do in order to do so. Once I learn I am sure to give further backtraces in future.
Obviously the X screen stops updating when you use gdb to stop KWin and the compositing it does. You need to run gdb from text mode.
This is still effecting - kde 4.0.3 I have tried (unsuccessfully) many times to get a backtrace. I have now got gdb to continue however no output ever appears. Please will somebody provide example lines so I can provide a backtrace and hopefully start solving this very serious bug (i have tried asking at various forums with no response..) This is what i am doing From console in kde (as root) # ps aux | grep kwin (to find kwin pid) # gdb kwin (pid) I turn logging on by # set logging on I then try to debug by using # continue - after using continue I can start to use kde (kwin) again, however no more output is created. Can someone please point me in the right direction I must be doing something wrong............

Can any one help - still effecting opensuse 11.0 - 4.0.4 and 4.1 beta.........
I mean aany working examples of how to give a backtrace for kwin..

Created attachment 28154 [details] valgrind
Comment on attachment 28154 [details] valgrind I'm using ubuntu intripid, with a nvidia quadro 140M. Everytime I try to use sharpen desktop or looking glass zoom kwin seems to lock up. gdb doesn't gave any usefull information at the time off the lock up. You find the valgrind log in the attachment.
looking glass and sharpen desktop is working in the nightly build off kde 4.2.
Morgan, can you reproduce with the latest KDE 4.2 betas and latest graphics drivers? Also maybe try with `KWIN_DIRECT_GL=1 kwin --replace &` if it doesn't work straight away.
Whoops, didn't need to close it.
I shall try shortly and post back results.
When using sharpen desktop I see the same behavior as siegfried: kwin locks up. I can move my mouse, but cannot do anything usefull anymore with my desktop. graphics card: nvidia quadro 140M graphics card driver: 180.22 KDE: 4.1.96 Distribution: Arch Linux
I was to optimistic. I'm working with kde 4.2 final in ubuntu jaunty at the moment. And I'm still experiencing the lock up. I'm almost starting to think that it has something to do with this specific nvidia card.
Still happens with kde 4.2 (ubuntu x86_64) Kwin however is massively improved in speed (seems like about 1000% faster) and more stable. If someone here provided a step by step instructions of how to provide a backtrace (i.e dont just point me to the kwin gdb page as that hasn't helped)I would happily provide one. i.e if someone could provide example of how they get their's..... kde 4 is now (with the exception of a few kwin issues) looking so good ! thanks
can someone please try with rev 960039 ( http://websvn.kde.org/?view=rev&revision=960039 )?
(In reply to comment #21) > can someone please try with rev 960039 ( > http://websvn.kde.org/?view=rev&revision=960039 )? or with KDE 4.2.3?
Thanks the bug is solved for me. I'm running kde 4.2.3 at the moment.
