I'm not sure what's creating that file causing the problems: /etc/X11/xorg.conf.d/20-intel.conf
Maybe you've experimented with a PPA in the past that modified your graphics packages? You can also find out by running: dpkg -S /etc/X11/xorg.conf.d/20-intel.conf Anyway, the point is that config file should not exist on a clean Ubuntu system. -- 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/1867668 Title: Visual artifacts in Gnome Shell when using the 'intel' Xorg driver To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1867668/+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
