> Are you using a particular screensaver "hack"? Like a 3D one?
Nothing more than clicking on the "Lock Screen" Action Button. I didn't do any configuration of xscreensaver in either a gui control panel or in a config file somewhere. > Or a random one, in which case you may try out cycling through the different screensavers until you see corruption. That would also be a driver issue, although in mesa/kernel, but it would help to pinpoint what exactly triggers it. I will do some experiments. I should note that, in the interim between 8 days ago and today when I've had a chance to look at this again, the problem has occurred after being logged in for that entire time without locking the screen. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/955585 Title: garbled text in emacs and odd colors in xfce4-terminal after being logged in for a while To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/955585/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
