hi,
you're right about the fact that it's obviously a problem with qt/e.
don't know how to solve that one. anyhow, i'm using my g400 so that it's
only connected to a tv. this is what I do:
matroxset -f /dev/fb0 -m 5
matroxset -f /dev/fb0 -m 2
matroxset -f /dev/fb0 -o 1 1
as i understand, the first line disconnects fb0, the second one connects
fb0 to secondary output of the card (tvout) and the third line tells the
kernel to use that (secondary) output, and use it in pal mode. or
something similar to that.
in addition, i set the resolution of fb0 to match my pal tv
(720x576 at 32). I user the following modelines, work fine for me.
mode "tvout"
geometry 720 576 720 576 32
timings 34404 24 0 82 63 48 13
vsync high
bcast true
accel true
rgba 8/16,8/8,8/0,8/24
endmode
after that, everything works pretty well. in addition to mythtv, i can
run pretty much anything on the tv, and the quality of g400 tvout is
excellent. there are some bugs in the qt/e mode of mythtv (most
annoyingly the epg while watching live-tv doesn't seem to work), but
it's certainly usable.
good luck, juhis
