I ran into this same problem on 2 machines I updated today. I also ran into the 177 vs 173 problem. Downgrading to 173 fixed the second screen desktop. I run independent screens like most people writing here.
When I use an application launcher in the gnome panel to launch something the gnome-panel becomes non-responsive and consumes 100% of one cpu. 'killall'ing it brings up another gnome-panel which works so long as I do not launch something from the screen 1 gnome-panel. I can launch things from the gnome menu successfully, but launching from an custom application launcher causes the lockup. -- two xscreens -> gnome panel crashes https://bugs.launchpad.net/bugs/278261 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-panel in ubuntu. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
