Unfortunately, nouveau makes laptops with a Pascal dGPU (GeForce 10xx series) really unstable.
For example my Dell XPS 9560 with a GTX 1050 won't boot without "nouveau.runpm=0". With "nouveau.runpm=0", boot will be slow, and multiple freezes with a recovery a few seconds later will occur after graphical login. The system remains sluggish even as the iGPU is used. See: https://bugs.freedesktop.org/show_bug.cgi?id=100228 (there might be other bugs affecting general stability with Pascal dGPUs) If I blacklist nouveau completely (both as a kernel boot option and in /etc/modprobe.d/), the system will function normally, but the dGPU will stay on. Forcing the use of nouveau on these recent laptops, especially for a LTS, really is a step backwards compared to what we had in 17.10. ** Bug watch added: freedesktop.org Bugzilla #100228 https://bugs.freedesktop.org/show_bug.cgi?id=100228 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1765363 Title: prime-select intel is not powering off the nvidia card To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-prime/+bug/1765363/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
