I experienced a similar situation with a fresh installation of Ubuntu Gnome on Dell XPS 15. I didn't install virtual box.
Details about my computer: Processor: Intel® Core™ i7-7700HQ CPU @ 2.80GHz Graphics: GeForce GTX 1050/PCIe/SSE2 Driver: Nvidia binary driver version 384.90; Processor microcode from intel-microcode(proprietary) After running "prime-select intel" and log out, I couldn't log in again. When I tried to log in, the screen just blanked out and got back to log in screen after a few seconds. After I run "prime-select nvidia" in tty to restore settings, I can log in. The solution on #11 didn't work for me. It successfully shut down the graphics, but I couldn't open GUI anymore and had to reboot to power up the graphics. However, I did find some workaround if you just want to reduce the power consumption. Instead of shutting down the graphics, you may constrain the clock rate by using this method: https://devtalk.nvidia.com/default/topic/572053/linux/-solved-forcing- maximum-power-saving-on-the-desktop-quot-minimum-power-quot-mode-for- powermizer-/ It worked on my computer and helped me to get rid of the annoying sound from GPU fan. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1637733 Title: freeze on login with prime-select intel To manage notifications about this bug go to: https://bugs.launchpad.net/lightdm/+bug/1637733/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
