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 Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1752053 Title: nvidia-390 fails to boot graphical display To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mesa/+bug/1752053/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
