Just to fill in my little bit of experience (as I've been reading about the same glitch I notice): other than the prettyor ugly workarounds proposed in this thread, Ctrl-Alt-Bksp works as well.
I'm running on a toshiba satellite P200, with GM965/GL960 integrated chip, and I've noticed a couple more behaviours not listed here: 1) When restoring from screensaver's screen power off, I see the normal desktop screen as if the screensaver never kicked in (windows are all there), I can move the pointer around, but it's as if the screensaver was actually on; in other words, it's a variant of the "blank frozen screensaver" where instead of the blank screen I see the normal desktop with which I cannot interact; more often than not, when that happens, after a while the screen goes back to blank and I get the regular password dialogue, from which I can then proceed to uset he laptop normally; this time though, it just stayed like that, visibile windows on the background, pointer moveable with no effects whatsoever... Ctrl- Alt-Bksp for me 2) If I try and do ctrl-alt-f1, and then again ctrl-alt-f7, I often get no the blank screen anymore, but the last text screen before gdm started, as if I had set the verbose boot mode on, but that screen i cannot interact with, I can type characters in there that are displayed on screen, but issuing commands or key combinations deals no effect (including ctrl-alt-bksp); sometimes, switching back to ttty1 and then to ctrl-alt-f7,a few times, shows the blank screen again, and I can ctrl-alt-bksp out of it. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/740126 Title: Disabling an output can cause vblank events to be missed To manage notifications about this bug go to: https://bugs.launchpad.net/unity/+bug/740126/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
