[mgp-users 00934] Re: Problems embedding apps in presentations

[Grunde L|voll <grunde.lovoll@fys.uio.no>]

Thanks again,
both (1) and (2) allmost works. Everithing works fine until I try to play
a mpeg-video (with mplayer or gtv) inside the presentation. Then I get the
following error message (in the terminal where I  started (x)mgp):
  .
  .
  Linux RTC init error in ioctl (rtc_pie_on): Permission denied
  Using usleep() timing
  Input config file /etc/mplayer/input.conf parsed : 50 binds
  .
  .
And the presantation freezes, but I'm able to go to the other X-session
with Ctrl-Alt-F7 and kill the prosess.

When I ran mgp without a wm  and with a single X-session as proposed in
another post on the list the videoplayer worked. Other X-apps like xeyes
or xclock works under both (1) and (2). So the question is if there is
something wrong with my videoplayer or the resources avalible to X in the
secon session? Would it help if the xmgp script is owned by root with
the sticky-bit set? It would be really neat to hav this thing working in
a secon X-session, and be able to switch between the presantation and the
desktop during presentations or while writing the presentation...
