[Bug 235171] New: qemu freezes machine during fullscreen switch
https://bugzilla.novell.com/show_bug.cgi?id=235171 Summary: qemu freezes machine during fullscreen switch Product: openSUSE 10.2 Version: Final Platform: i686 OS/Version: Other Status: NEW Severity: Normal Priority: P5 - None Component: X.Org AssignedTo: sndirsch@novell.com ReportedBy: ssommer@novell.com QAContact: sndirsch@novell.com Sometimes when I start qemu in fullscreenmode or switch to fullscreenmode the machine will hang completely (keyboard dead, no ping etc...) This happens with the opensource nv driver and a flatpanel connected with dvi. The nvidia driver works fine. I tried another machine with a TNT2 card and a CRT and the problem was not there either. Changing the resolution multiple times with xrandr works fine, too. I attached a small SDL program containing the critical SDL calls that will trigger the hang. Would be nice if someone could test if it happens for him, too. It requires the SDL devel packages and can be compiled with gcc -o main main.c -lSDL Maybe my hardware is somhow broken. When I disable dma with Option "NoAccel" "true" in the xorg.conf it works without problems. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

Of course this is no valid workaround. I'm afraid this is something for NVIDIA to investigate. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
