X Crashes When Switching Virtual Terminals And Using Rhythmbox
Last modified: 2007-11-30 17:12:07 EST
Switching to the console (Ctrl+Alt+F1) and back again (Alt+F7) while Rhythmbox is playing will result in your X session crashing and disappearing, after which gdm promptly creates a new login screen. 1. Login to X. 2. Start Rhythmbox and ensure it's actually playing music. (or paused, more on this later) 3. Switch to console (Ctrl+Alt+F1) 4. Switch back (Alt+F7) X will at this point go down with the following stack trace being printed to logs: Backtrace: 0: /usr/bin/Xorg(xf86SigHandler+0x6d) [0x47f5ed] 1: /lib64/libc.so.6 [0x38fa030620] 2: /usr/bin/Xorg [0x48eb91] 3: /usr/bin/Xorg [0x48f055] 4: /usr/bin/Xorg(TraverseTree+0x33) [0x4361b3] 5: /usr/bin/Xorg [0x48f0d0] 6: /usr/bin/Xorg(xf86Wakeup+0x3ea) [0x480a7a] 7: /usr/bin/Xorg(WakeupHandler+0x51) [0x44f101] 8: /usr/bin/Xorg(WaitForSomething+0x1d4) [0x565184] 9: /usr/bin/Xorg(Dispatch+0x9a) [0x44b19a] 10: /usr/bin/Xorg(main+0x45d) [0x43404d] 11: /lib64/libc.so.6(__libc_start_main+0xf4) [0x38fa01daa4] 12: /usr/bin/Xorg(FontFileCompleteXLFD+0x231) [0x433319] Fatal server error: Caught signal 11. Server aborting Originally this was thought to be due to the proprietary nvidia driver and it took some time to isolate Rhythmbox as the determining factor in the crash. However once this was discovered I can now replicate the crash 100% of the time using the nv driver as well. I cannot test other video drivers as I have none at my disposal, but given that it 's unlikely to be a hardware problem (I've used this functionality for years on this hardware) I'm under the assumption that the video driver doesn't really matter. Problem is also apparent when switching to another X session (via user switcher applet where the problem first surfaced, or spawning a new gdm session and switching back and forth with Ctrl+Alt+F9 etc). The problem appears to be specific to Rhythmbox and not sound in general, the crash does not seem to occur with Totem or vlc playing. Also, Rhythmbox must be playing or paused: - Open Rhythmbox but play nothing = no crash - Open Rhythmbox, play something = crash - Open Rhythmbox, play something, pause = crash - Open Rhythmbox, play something, close Rhythmbox = no crash
I can also reproduce the problem using the fast user switch applet or using the keyboard shortcuts to change console in FC7.
Also reproducible on a non-64 bit system (i686), also Fedora 7.
Forgot to mention, my system is x86_64.
Recent updates (xorg as well as several x drivers) seem to have taken care of this problem. I can no longer replicate the crash with Rhythmbox playing, just notice a very brief interruption in sound but everything works fine.
I can also confirm that this bug seems resolved using the latest xorg-x11-server-Xorg for f7.
