I tried strace, but I was yet not able to find any abnormal behaviour visible via strace when I switch to VT and back.
I tried gdb, and it did showed following. Each time I stoped program in gdb to show it current bt, it was in select(), both when normally working and while hanging (when on other VT). Only thing so far I noticed is that while in other VT, then atop cpu usage kaffeine=3% pulseaudio=~0%, and in same VT kaffeine=6% pulseaudio=5% All the above is on geforce 2 mx gfxcard; Section "Device" Identifier "Device0" Driver "nvidia" # VendorName "NVIDIA Corporation" EndSection #0 0xb7f9e410 in __kernel_vsyscall () #1 0xb63aa881 in select () from /lib/tls/i686/cmov/libc.so.6 #2 0xb6a930e3 in QEventLoop::processEvents (this=0x81c9eb0, flags=4) at kernel/qeventloop_x11.cpp:294 #3 0xb6b08f90 in QEventLoop::enterLoop (this=0x81c9eb0) at kernel/qeventloop.cpp:201 #4 0xb6b08c8e in QEventLoop::exec (this=0x81c9eb0) at kernel/qeventloop.cpp:148 #5 0xb6aef7df in QApplication::exec (this=0xbfce3140) at kernel/qapplication.cpp:2761 #6 0x08075f40 in main (argc=22904, argv=0x0) at /build/buildd/kaffeine-0.8.6/./kaffeine/src/main.cpp:120 -- mplayer vlc kaffeine all players hang/pause when I switch away from the VT they use (to other desktop or terminal) https://bugs.launchpad.net/bugs/258158 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
