[mythtv-users] Front end locking up during playback all of a sudden, please help

[Patrick Quinn]

I've had a working mythtv machine for quite some time now.  It's
running Ubuntu Breezy and I haven't messed with any settings on
purpose in quite some time, though I use the machine as a web and file
server.  Out of nowhere my front end has started locking up after I've
been watching TV for about 20 minutes.  When this happens, top shows
the X server at 97% CPU, and I get something like the following in the
logs:

I'm using a GeForce FX 5200 with the proprietary nvidia drivers on
Ubuntu Breezy that hasn't been updated in maybe 4 months.  Here are
some relevant sections of my xorg config:


Section "Module"
        Load    "GLcore"
        Load    "i2c"
        Load    "bitmap"
        Load    "ddc"
        Load    "dri"
        Load    "extmod"
        Load    "freetype"
        Load    "glx"
        Load    "int10"
        Load    "type1"
        Load    "vbe"
EndSection
...
Section "Device"
        Identifier      "NVIDIA Corporation NV34 [GeForce FX 5200]"
        Driver          "nvidia"
        Option          "TVStandard" "NTSC-M"
        Option          "TVOutFormat" "COMPOSITE"
        Option          "ConnectedMonitor" "TV"
        BusID           "PCI:1:0:0"
EndSection


Does anyone have any idea of what could be doing this or where I could
look for more answers?
