Same thing for me here, and I also use the nvidia binary drivers (didn't try with an other driver though)
Further details : this problem started for me like a month ago, but switching from Ubuntu theme to Silicon theme made the problem disappear. Now, even with the Silicon theme, when I try to display the updates of today (06/07/06), it makes my X server crash. And...switching from Silicon theme to LegacyUbuntu theme solved the problem once again. It seems that it's getting worse given that it now occurs both with the Ubuntu theme and the Silicon theme. -- Selecting package in update-notifier crashes X11 session https://launchpad.net/bugs/50245 -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
