Hi Helmer,

I tested on KDE4 (4.8.4, Debian sid).

As anybody knows KDE4 has lots of problems with sizing and resizing of plasma panels, screen geometry and other stuff as usal.

Same with GNOME3 btw.

Please send the scripts to the x2go-dev list. Note: resizing of a plasma desktop works fine in KDE4 on Debian wheezy/sid.

My problem is that for plasma to assume the new resolution you have to kill it and start-it once again after you change plasma-desktop-appletsrc with the new values. So, when you do this after resuming the session, every time you move/maximize/minimize a window they slow to a crawl.

ahaaaa... this is not so here... Note: there is quite a big difference between the Ubuntu KDE4 and the Debian KDE4. Ubuntu has (at least one) xrandr patches that break KDE4 nearly completely with X2Go (KWin crashes regularly).

How to test/reproduce this sympton.

If you have a x2goserver installed with a kde4 session, kubuntu or other, start a session, go to konsole and do:

kquitapp plasma-desktop && plasma-desktop &

after plasma start if you try to move any window around everything will be allright and fast as before.

ok...

...

After that do the same thing but after a x2gosuspend and in a runing resumed session try to move your konsole window around the desktop, it will lag like hell. If you this on a real display on your laptop, or in a running session everything will run fast as before.

Not so here on Debian. It must be some Ubuntu specific issue.

Greets, Mike

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.

Hello Mike,

I've instaled OpenSuse 12.2 and everything with plasma is working fine. No kwin crashes, resizing works as expected when resizing the windows live.

I haven't have time yet to test suspending with a different resolution in full screen mode and restoring with another one in full screen mode.

Little bit tired now.

I'm a debian/deb lover and for the sake of god hate rpm, but debian have some problems too, with some legacy stuff like libreoffice and those iceweasel and icedove freaks, Lol.

Will evaluate OpenSuse and try to migrate my already done settings/kiosked interface/menus from the kubuntu dev machine to OS.

regards,
