This also affects me on 17.10. would changing to 16.04 restore the expected behavior? I could wait 2 years for the next LTS, hopefully this issue would get solved by then. And until then I'd be able to switch without restarts.
I wonder when, if ever, we'd get to not needing to logout\login to switch between the GPUs (like it currently is under Windows and MacOS). -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to nvidia-prime in Ubuntu. https://bugs.launchpad.net/bugs/1765556 Title: nvidia-prime needs a reboot to switch between dGPU/hGPU Status in nvidia-prime package in Ubuntu: Confirmed Bug description: I previously used Ubuntu 16.04 and Nvidia 375 driver with a Nvidia Geforce 635M and Sandy Bridge i7. To switch between the 2 Optimus cards (Intel hybrid and Nvidia discrete), one had to go into nvidia- settings, switch, logoff, login back, and the change was applied. I now have a Nvidia Quadro M2000 and a Skylake Xeon which has some Sync/Mux feature (whatever does that mean) with the Nvidia 390 driver. First of all, installing nivida-prime doesn't install bbswitch-dkms. Then, once the GPU switch is made, it triggers update-initramfs, recompile the kernel modules, and one needs to reboot the system to get the GPU change. Even when we install bbswitch-dkms. So am I getting a wrong impression or is there something twisted here ?
