I'm facing the same problem with Ubuntu 20.04.1 LTS and GeForce 310M, using an old Samsung QX310.
Without these drivers, the preinstalled intel driver works fine. But with "prime-select intel" I boot into a black screen. To go back into the DE, first I have to press Ctrl+Alt+F4 and then input my login and password. Sometimes it takes a few tries. I hope this helps others, so that booting into recovery mode is not needed. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1848326 Title: [cosmic+] error booting with prime-select intel: prime-select does not update initramfs to blacklist nvidia modules To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-prime/+bug/1848326/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
