Adrian, thank you very much. Your advice saved me a lot of money. I unfortunately own an MSI GX70 notebook with two GPUS: Radeon HD 8650 G Richland and Radeon HA 8970 G Neptune.
It wouldn't load without nomodest option in grub configuration. While fglrx lasted, it was bearable. After 16.04, however, nomodeset started to block installing amdgpu driver. With MUTTER_ALLOW_HYBRID_GPUS=1, however, the notebook booted without nomodeset, also it switched to integrated Radeon HD 8650 G Richland automatically. I will still have to figure out how to switch to the discrete GPU when it is required but the notebook is already getting to be usable again after one and a half years. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1724583 Title: gdm3 in Ubuntu 17.10 doesn't list wayland sessions when using hybrid graphics Status in gdm3 package in Ubuntu: Confirmed Status in gnome-shell package in Ubuntu: Confirmed Status in gdm3 package in Fedora: Confirmed Bug description: I've just upgraded to Ubuntu 17.10 and switched the login manager from sddm to gdm3.
