Does Xorg crashes back to a login prompt, or is it just just
mythfrontend that crashes (and so takes you back to your desktop). If
Xorg crashes, then this is most likely a duplicate of

Status in “mythtv” package in Ubuntu: Incomplete

Bug description:
Binary package hint: mythtv

New install over erased hard drive.
On power up mouse frozen on log in dialog (unfroze after plugging in a second usb mouse).
Setup only detected 3 of the 4 tv tunners (2 dual cards). These cards appear as usb devices.
Tried to watch tv but crashed.

I have had similar problems on all mythtv versions after 9.04 (something to do with udev ?).

1/ dogphlap@dogphlap-P5Q-PRO:~$ lsb_release -rd
  Description:    Ubuntu maverick (development branch)
  Release:    10.10
3/ I hoped the mouse would work for loging in.
    I hoped all 4 tuner cards would be found.
    I hoped myth would not crash when selecting watch tv.
4/ mouse frozen until another usb mouse plugged in.
    only 3 of 4 tuners detected.
    selecting watch tv caused a crash.
