I had a similar problem. The root cause is that upgrading via systemsettings or `apt-get upgrade' will install only about half the packages you need, leaving KDE unbootable. To get a working system, first add the PPA as described in the instructions, and then quit systemsettings without installing or upgrading anything. Open a Bash prompt (in Konsole, for example) and run the following commands:
sudo apt-get remove plasma-widget-fancytasks sudo apt-get update sudo apt-get dist-upgrade You'll probably be asked for your password by the first of these commands, and also by the others if you don't run them soon enough. Removing the fancy-tasks widget (if you have it) is essential, because it causes KDE 4.4 to crash very soon after you log in. If you don't have this package installed, the `apt-get remove' command will fail; this is not a problem: just move on to the other commands. Although I've not tried it, I imagine these three commands could also be used to rescue a half-upgraded KDE system that won't run. Drop into a virtual console by typing Ctrl+Alt+F1 (if you're on a PC) or RightCtrl+F1 (if you're in VirtualBox), log in, run the three commands, and reboot (on a PC) or restart the VM (on VirtualBox). -- KDE-4.4 upgrade causes desktop crash https://bugs.launchpad.net/bugs/520978 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
