So it is an attempt to raise more attention, as HDMI currently isn't usable for me on Ubuntu 18.04 (it affected me on 16.04 as well). Put in short, after Nvidia drivers are installed and I switch from Nvidia card to the intel one, the GUI can't be opened anymore To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-390/+bug/1773113/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
