I am also encountering this bug, after upgrading from Kubuntu 17.10 to 18.04.
For me, initially only my Intel driver wouldn't work (with PRIME) - it would instead just go ahead and use the NVidia driver (even when PRIME said Intel was in use). However, upgrading to {xserver-xorg-video-nvidia-396,nvidia-driver-396 ,nvidia-utils-396} via the graphics-drivers ppa results in neither operating correctly and the fallback llvmpipe software renderer being used. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to mesa in Ubuntu. https://bugs.launchpad.net/bugs/1752053 Title: nvidia-390 fails to boot graphical display Status in mesa package in Ubuntu: Fix Released Status in nvidia-graphics-drivers-390 package in Ubuntu: Fix Released Bug description: I'm using Bionic with the new 4.15 kernel. I've been using the nvidia-384 driver with no problem for a while. Today I issued "sudo apt-get upgrade" and I was prompted to upgrade the nvidia driver to the nvidia-390. After installing the driver and rebooting, I was only able to boot in to the tty terminal. The graphical display failed to boot. I have had similar problems with nvidia driver version 390 with Arch Linux and with Open Suse Tumbleweed.
