Client VTs/screen-sessions are mixed up

[Alkis Georgopoulos]

Using Lucid alpha3, manually updated to trunk revision 1703.
I hadn't noticed this issue before Lucid.

I have SCREEN_02=shell and SCREEN_07=ldm in lts.conf.

Sometimes everything goes as expected,
but sometimes ldm starts on top of the shell on VT2,
and sometimes ldm starts on VT1.

Here's a `ps` from when ldm is erroneously started on VT2. The openvt calls seem ok:
root 989 955 0 21:13 ? 00:00:00 /bin/openvt -s -f -w -c 2 -- /usr/share/ltsp/screen.d/shell
root 990 965 0 21:13 ? 00:00:00 /bin/openvt -s -f -w -c 7 -- /usr/share/ltsp/screen.d/ldm

Maybe X uses the active VT, so we should change the chvt call to ensure that we always switch to the ldm (or rdesktop...) screen?

I also have this problem with an empty lts.conf, i.e. ldm sometimes gets on top of VT1.

I'm also affected by this, but i couldn't reproduce this at will.

when i do `chvt 1` then pkill X, X start on vt1.

I will do some more testing.

#ltsp on freenode.

<Gadi> mgariepy: can you try calling this in screen_session: ${openvt} -s -f -w -c ${TTY_NUM} -- TTY_NUM=${TTY_NUM} ${SCRIPT_DIR}/${SCREEN_SCRIPT} ${SCREEN_ARGS}&
<Gadi> mgariepy: and then have screen-x-session use TTY_NUM
<Gadi> mgariepy: instead of fgconsole

[Marc Gariépy (mgariepy)]

i tried to define an environment variable with openvt but it doesn't work so now screen_session have fewer tests.

screen-x-common uses tty instead of fgconsole

Can someone tests the new release of those scripts and report any issue please.
