Forgot to mention the version number - it's
mythtv-frontend_0.21.0+fixes16838-0ubuntu3_i386:
MythTV Version : 16838
MythTV Branch : branches/release-0-21-fixes
Library API : 0.21.20080304-1
Network Protocol : 40
Options compiled in:
linux debug using_oss using_alsa using_arts using_jack using_backend
using_dbox2 using_dvb using_firewire using_frontend using_hdhomerun
using_iptv using_ivtv using_joystick_menu using_libfftw3 using_lirc
using_opengl_vsync using_opengl_video using_v4l using_x11 using_xrandr
using_xv using_xvmc using_xvmcw using_xvmc_vld using_glx_proc_addr_arb
using_bindings_perl using_bindings_python using_opengl
using_ffmpeg_threads using_libavc_5_3 using_live
Please note - and I'm already kicking myself - that it could be unrelated
to mythtv as it doesn't happen using a different (fresh) user account
under a second x session.
thanks
