Update regarding 17.10 - After switching from GDM to lightDM, logout and login are enough, no reboot required. With GDM, logout and sudo systemctl restart display-manager was also enough and didn't require a full reboot.
This is for nvidia-prime 0.8.5, kernel 4.13.0-41-generic and 390.59-0ubuntu0~gpu17.10.1 - but for 0.8.8 on Bionic Beaver (also 390 drivers) a reboot was required even with lightDM instead of GDM, and restarting the display-manager wasn't enough as well.. So I'd say it's a regression in 0.8.8, wouldn't 0.8.5 work with the latest drivers and kernels? It could be a workaround for now to revert back to 0.8.5 for Bionic Beaver. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1765556 Title: nvidia-prime needs a reboot to switch between dGPU/hGPU To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-prime/+bug/1765556/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
