Updating to `proposed` did not help me. I've tried uninstalling/purging `nvidia-*` and installing it back, still having the black screen.
Tried to switch to Intel adapter using prime-select, it complains that it's not supported. Purging nvidia-390 and installing nvidia-340 works (though Nvidia always runs on top clock, even on battery, overheating my knees, and always on 100% brightness) Dell Latitude 6430, NV520. -- 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/nvidia-graphics-drivers-390/+bug/1752053/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
