The cut and paste below was my comment on your other bug. So i just wanted to include it. This bug posting though explains exactly what was happing to me right down to the blinking _ in the upper left and freezing, however for me it also kicks off the display completely and am presented with a no connected device message on my screen.
The reason why there is nothing you can do to get out of it (exept powerdown the pc or wait as after a few minutes it will restart itself) is because at the time the display crashed it was also brining down your keyboard. The keyboard would normally be brought back up right after display did not load the keyboard did not boot up. You will notice when this happens by all the keyboard lights going out. I came to this conclusion after realising in a working install environment the keyboard is brought down and back up right before gdm kicks in. ##### CUT/PASTE my comment on bug #661235 ##### You wouldn't by any chance have a dual display set-up or be using a non VGA connection are you. Even if your are not check your bios and see if dual display is enabled (Advanced Chipset in my bios). I found if it is enabled and set to primary video AUTO or PCI-E and you are using a (in my case) HDMI connection the install will fail. Fails right after plymouth and just flashes a blinking _ in the upper left. Eventually displays Samsungs default NO Connection Msg. My Setup is: 1 TV Plugged in threw HDMI 1 CRT monitor plugged in threw onboard VGA BIOS / Advanced Chipset 1.) Dual Display - Enabled // Primary Video - Auto ---> Will NOT work (displays on flatscreen) Dual Display - Enabled // Primary Video - PCI-E ---> Will NOT work Dual Display - Enabled // Primary Video - VGA ---> Works Everytime (if you also have a old CRT monitor connected) 2.) Dual Display - Disabled // Primary Video - Auto ---> WORKS (displays on flatscreen) Dual Display - Disabled // Primary Video - PCI-E ---> WORKS Dual Display - Disabled // Primary Video - VGA ---> WORKS * I recall one of the above 3 getting past install but then failing after restart with same black screen. I think it was auto. Unfortunately I forgot to document that one. But I have documented that PCI-E did work, so its not clear to me why auto would fail and PCI-E would work when they both were using the PCI-E connection. This might have just been a mishap but after trying to install so much once it got installed I did not want to try to recreate problem. Can someone verify? 3. (HDMI Connection and a VGA to DVI Adapter Connection) Dual Display - Enabled // Primary Video - Auto ---> WORKS (displays on flatscreen) Dual Display - Enabled // Primary Video - PCI-E ---> WORKS Dual Display - Enabled // Primary Video - VGA ---> WORKS So to me it appears this driver does not work properly with the BIOS having Dual Display Enabled. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/713867 Title: Live-CD and Installed Ubuntu freeze on boot with GeForce 210 / Nouveau -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
