sorry .. the problem still remains .. so forget my previous posts :( It seems a problem of memory: if I switch without any app opened everything go right, but if just open some firefox wins and a openoffice document and then try to switch get the blank screen ..
I tried to use the User Switcher panel applet, instead of the Indicator Applet Session as suggested here https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/546578 and that seems to work with all desktop effects turned off. However even in this case if I close all the user sessions through the User Switcher panel applet the gdm panel is no more shown and can only press ctrl+f1 login and write sudo /etc/init.d/gdm restart to get it. -- black screen when switching between multiple X session https://bugs.launchpad.net/bugs/529882 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-ati in ubuntu. _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
