Timo, I made that change, then booted 11 times. 4 of the 11 boots were successful. The other 7 times I was left looking at a blank screen or the Ubuntu logo. In those cases I was able to switch to virtual terminal 1 and log in in text mode. I never once ended up in low- graphics mode with the "no screens found" error in the X log, though I'm not entirely sure whether that was due to your change - this behavior is nondeterministic so it's hard to tell. By the way, I've sometimes seen boots end up with a blank screen like this even before your change.
I'll attach the X server log file as it appeared after one of these bad boots into a blank screen. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1161371 Title: X server sometimes fails to start on MacBook Air 5,2: no screens found To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1161371/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
