One more to report, this one got my son's computer, an older Asrock machine. Uninstalling the nVidia drivers allowed booting into the desktop but then when none of the available nVidia drivers worked we made the mistake of trying to install the Linux driver from nVidia's site. Apparently somewhere in the process it uninstalled the Noveau drivers and now we can't even log into the system except via ssh.
I then tried reinstalling the Noveau package xserver-xorg-video-nouveau and it claims it cannot be installed because The following packages have unmet dependencies: xserver-xorg-video-nouveau : Depends: xorg-video-abi-15 Depends: xserver-xorg-core (>= 2:18.104.22.1682) Recommends: libgl1-mesa-dri (>= 9.0) If I tried to reinstall the xorg/xserver stuff, no matter what I tried I kept getting these: The following packages have unmet dependencies: unity-control-center : Depends: libcheese-gtk23 (>= 3.4.0) but it is not going to be installed Depends: libcheese7 (>= 3.0.1) but it is not going to be installed E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages. But if I try to install those I get: libcheese-gtk23 is already the newest version. libcheese7 is already the newest version. And if I tried to force install them, it showed that it is already running libcheese-gtk23:amd64 (3.10.2-0ubuntu2) and libcheese7:amd64 (3.10.2-0ubuntu2) which are both higher versions than what xorg seems to require, so I don't understand what is going on here. Anyway, at this point the system is pretty much totally broken as far as getting into the desktop is concerned. Is there any chance you can fix this and get a new kernel update out very soon, like tonight or tomorrow? Because if not, it looks like I may have to reinstall from scratch, and even then I'm not entirely certain I won't run into the exact same issue. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1750937 Title: 14.04 Kernel update on 2/21 breaks Nvidia drivers To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1750937/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : firstname.lastname@example.org Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
