This is an old bug I reported already in the old forum, and that I have been encountering for years despite the changes in hardware and software on my systems (7600GT, 8800GT and now GTX460 cards; Althon XP 3200+, Core2 Quad Q6600 and now Core-i5 CPUs; Mandriva 2007.1, 2008.1, 2009.1 and now 2010.2 distros; Linux kernel (vanilla) from v2.6 to v3.9; Sawfish window manager, all versions including the latest ones; Second Life viewers, v1, v2, v3, official and third party viewers; all NVIDIA drivers versions).
The symptoms are: while the Second Life viewer is running (this is about the only OpenGL application I use, but I’d bet it would happen with any OpenGL app) on one workspace, it sometimes (like 1 time every 10 times) crashes when I switch to another workspace.
The viewer provides a stack trace on crashes, and it always point into libnvidia-glcore.so and is always accompanied with a “NVRM: Xid” message in /var/log/messages (see the attached stack trace and bug report files).
Please, could someone at (loooooong) last look into this extremely annoying issue ?..
Many thanks in advance !
