I am new to bug reporting so apologies if I'm doing this wrong. It seems I am also affected by this. I tried the upgrade from mate 17.10 to 18.04 with nvidia installed which lead to a black screen. Then I tried upgrading first and then installing nvidia also a black screen. I have a Lenovo w550s with a quadro k620m. Commenting out the "Primary GPU" line in
/usr/share/X11/xorg.conf.d/11-nvidia-prime.conf and setting the file immutable seems to work. Nvidia settings shows my GPU is used. However, running glxinfo I get the following error Error: couldn't find RGB GLX visual or fbconfig so I cannot confirm Please let me know if I can provide any further information. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1764005 Title: Black-screen on boot with nvidia 390 for Budgie, MATE, Xubuntu, Kubuntu To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-prime/+bug/1764005/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
