Hi, Mike,
hi list members.
I'm still debugging what the hell is going on.
what i have gathered so far is that is if i run the scripts inside a konsole
after resuming the session, everything will work as fast as before.
If i run-it from any script from x2go scripts it has the problem of lagging a
lot.
I think that it has to do with dbus.
All Scripts below. There are two kind of scripts:
One is for locking the session after a user suspend the session for security
concerns, i also developed a login gui with lazarus so that a user has to
enter his password before starting is session.
The others are to resize kde panel and display geometry, also to adjust
wallpaper to the screen. All of this things are not working in kubuntu when
you connect with different resolutions. I'm testint in a kvm windows xp with
rdp client with two different users, which one with is resolution.
Some of the scripts doesn't make sense to put here. :-D
/usr/local/bin/startkde
#!/bin/bash
fn_start_session()
{
/usr/local/bin/fn_resizepanel.sh
/usr/local/bin/fn_getmounts.sh &
/usr/bin/startkde
/usr/local/bin/fn_cleanpclocal.sh
/usr/local/bin/fn_cleanprinter.sh
}
fn_abort_session()
{
x2goterminate-session $MYSESSION
exit 0
}
MYSESSION=`x2golistsessions |cut -d '|' -f2`
SESSIONDP=`x2golistdesktops |cut -d : -f 2`
export DISPLAY=:${SESSIONDP}
xli -fillscreen -onroot /usr/share/wallpapers/spikepwd.jpg &
# Call the login lazarus app
/usr/local/bin/Spikepwd
retval="$?"
if [ "$retval" == "0" ]; then fn_start_session
else
if [ "$retval" == "255" ]; then fn_abort_session
fi
fi
exit 0
----------------------------------------------------------------------------------------------------------
/usr/local/bin/fn_post-resume.sh -> this one it is called at post-resume.d
#!/bin/bash
resize_screen()
{
SESSIONDP=`x2golistdesktops |cut -d : -f 2`
export DISPLAY=:${SESSIONDP}
/usr/lib/kde4/libexec/kscreenlocker --forcelock --showunlock --blank &
kquitapp plasma-desktop
sleep 2
/usr/local/bin/fn_resizepanel.sh
sleep 1
plasma-desktop
kdialog --passivepopup 'Por favor aguarde, a restaurar a sua sessão ... ' 10
}
resize_screen &
/usr/local/bin/fn_getmounts.sh
exit 0
P.S: this is the problem that i'm facing. if you open a konsole or xterm and
call this script kwin will run greatly and fast, but when called from
x2goscripts it lags when moving, minimizing, restoring windows
----------------------------------------------------------------------------------------------------------
pre-runcommand.d
#!/bin/bash
MYSESSION=`x2golistsessions |cut -d '|' -f2`
myCMD=`x2gocmdexitmessage $MYSESSION`
if [ "$myCMD" != "exec startkde" ]; then
/usr/bin/logger -t HACKING_ATTEMPT $USER tried to $myCMD
x2goterminate-session $MYSESSION
fi
exit 0
----------------------------------------------------------------------------------------------------------
pre-suspend.d
#!/bin/bash
kdialog --passivepopup 'Por favor aguarde, a suspender a sua sessão actual ...
' 5 &
/usr/local/bin/fn_cleanpclocal.sh
/usr/local/bin/fn_cleanprinter.sh
sleep 1
SESSIONDP=`x2golistdesktops |cut -d : -f 2`
export DISPLAY=:${SESSIONDP}
/usr/lib/kde4/libexec/kscreenlocker --dontlock --blank &
exit 0
----------------------------------------------------------------------------------------------------------
scripts end

Been triying messing with dbus but to no avail till now.
All my testing till now, commented and not commentd but still the same
problem.

"^DBUS_SESSION_BUS_ADDRESS=")
DID=`echo $DBUS_SESSION_BUS_ADDRESS |cut -d '=' -f 3 `

remember: whatever i do, this process always works when after resuming you
open a konsole and exec fn_post-resume.sh
