I have an exactly similar issue. I have Intel 82815 graphics controller. On upgrading to Lubuntu 14.10, I hit the same white screen mentioned above. I had to finally reinstall Lubuntu 14.04 to get things working back. And I am not going ahead with the updates for now, which of course is not a long term solution.
The first time I boot up my computer, the grub screen shows and on selecting Ubuntu, the boot up text (I have disabled quiet option) is all garbled up. On rebooting, this starts showing correctly. The video colors are also distorted. This is when I see mp4 videos using gnome player. The same mp4 video shows correctly when I see it in Windows on the same PC. So its not a hardware issue, but likely to do with video drivers. I have tried updating the drivers by downloading them from Intel website, but that hasn't helped. So looks like there is an existing problem with Intel 82815 drivers in 14.04 which has got worse in 14.10. Lubuntu is very popular with old PCs where Intel 82815 is quite common. So its important to have a solution to this problem. -- 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/1389904 Title: With the recent update to xserver-xorg-video-intel, system boots to a black screen To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1389904/+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
