Short story: About four days ago I installed the Nvidia-current display driver and removed the Nouveau display driver and my system has not frozen
Long story: To remove the “Nouveau display driver” first install the “Nvidia-Current” display driver. I ran into trouble because I removed the Nouveau -specific kernel DRM services -runtime and the “system settings” stopped working. Then I ran into more trouble because I removed the Nouveau display driver before installing the Nvidia-Current. Somehow I was able to go to a shell and installed the Nvidia-current driver with sudo apt-get -install nvidia-current (or something like that). That made the graphics work but still the “system settings” did not work. I reinstalled the Nouveau -specific kernel DRM services -runtime and the “system settings' still did not work. I found out that I needed to install or reinstall de Gnome-Control-Center and I did using “sudo apt-get -reinstall gnome-control-center” or “sudo apt-get -install gnome-control-center”. Since I kept uninstalling and reinstalling the “runtime”, the “reinstall” worked at one point but then it didn't so I finally used the “install”. My system has been working fine since then and has not frozen, but I'm not using the Nouveau Display Driver -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1242767 Title: computer freeze trying to exit "gnome-control-center" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-nouveau/+bug/1242767/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
