This problem began a couple months ago.

Try to play a MythTv recording, and Ubuntu logs out and immediately comes to the login screen. (worked fine w/o this problem for a number of years)

It is ready for me to log in, in only a few seconds, so it is not a full reboot, but all the previously opened programs are now closed.

Nothing similar happens when using any other program.

Here is my set up:

Ubuntu 10.10
MythTv version 23

AMD Athlon 64X2 5200+
1.9 GiB RAM
70 GiB free HD space

When I look at the syslogs, I wonder if this be some sort of "acpid" problem?

If I re-trigger the problem. The syslog System Log Viewer has this log each time I there is a log-out/crash/restart

Any ideas?

I'm not sure that this is related to acpid. At least from personal experience, when an application (in your case MythTV) makes you "logout" it's actually crashed the X server, which then automatically restarts and you wind up at the login screen.

Try checking the Xorg log file /var/log/Xorg.0.log (or something similar to that) and see what errors were produced.
Maybe also try searching Google for keywords like "xorg mythtv crash". Some of the results look promising and one indicates that your problem may be related to having transparency enabled.
Try running Mythtv from a console with the following command:

Post back with results

easuter, thank you very much for your input.

You must be right about the X server, Mythtv ran great when I ran it from a console with: NO_XV="1" mythfrontend

Side issue: After running it that way a couple times, I now have another problem. (no UPnP)


I don't recognise any errors in the Xorg.0.log - System Log Viewer

Also, I am not aware that I have transparency enabled. Unless it is part of the theme I am using "Clearlooks"
