locked windows with no titlebar after "start new session" KDE form previous KDE session
Last modified: 2006-05-07 11:38:03 UTC
Problem persists in Suse linux pro 9.2 as in Open Suse 10.0 final. I use KDE by default, my wife too. When I'm logged into KDE and I choose "Switch user" and then "start new session" from KDE menu, the new xserver starts in console vt8 and new KDM instance shows there. After loging into KDE session of different user the windows are VERY OFTEN BUT NOT ALWAYS locken into positions were they were opened. They don't have title bar or close, max, ... buttons. They are unmoveable even using ALT + LMB and I cannot resize them using ALT + RMB. It seems that this does not appear when I use "Switch user" and then "Lock session and start another one". It also do not happen when new session uses Gnome or other than KDE window manager. I think that problem may be related to binary nvidia gfx drivers. I use dual head configuration (one X server screen on TVout and second on DVI connected flatpanel). So after start new sessions the following two screens start. Moreover when I'm switching between the sessions I sometimes get corrupted screen. So I have to switch to the one of the six text consoles and thet to the graphical one and screen is OK. I have nvidia driver installed with fetch- nvidia.sh (driver version 76.76). The problem does not exist on my laptop on 9.3 and 10.0 SuSE Linux. The laptop has intel 8xx graphics card and single head x-server layout.
Try if the problem persists with the open source nvidia drivers. Check if process 'kwin' is running for the new user, if not, try to run it. If there's any crash information please provide it.
Indeed it depends on kwin is running or not. Sometimes it starts for new user in two instances sometimes not. I'll do the test with opensource nvidia driver at night, now I have go to work. Is it a good idea to add kwin into ~/kde/Autostart ??? I doubt it.
I cannot start the X without nvidia legacy drivers. I tried to change "nvidia" to "nv" in /etc/X11/xorg.conf, comented out Load "glx", rmmod nvidia. But X always starts using legacy driver. I tried to change "nvidia" to "vesa" in xorg.conf. Same result. I renamed nvidia.ko to nvidia.ko.bak so the module cannot be load and X refuses to start. Strange for me. It worked in fedore core. How to test it? PS: Comment to my previous comment, kwin either does not start at all or in two instances per user after starting new session.
I added soft link to kwin to ~/.kde/Autostart and it works good for now.
Do you have anything in ~/.xsession-errors or some core file that'd point out why kwin doesn't start up successfully?
we can't reproduce this and you did not provide the necessary info ;( if you can reproduce it with 10.1, please reopen the bug with the information. Thanks
