Help Test Intel+Nvidia Hybrid Graphics GDM3 Fixes In Ubuntu 18.04


Ubuntu 18.04 shipped with two issues for Intel+Nvidia hybrid graphics users: an increase in power consumption when the discrete GPU is off, and the inability to switch between power profiles with a simple logout (a restart is currently required).

These issues are caused by changes in logind, Nvidia drivers packaging (which is now more granular), and the migration from LightDM to GDM3, and they were fixed in Ubuntu 18.10 Cosmic Cuttlefish.

The fixes have been backported to Ubuntu 18.04, and are available for testing in the proposed repository.

If you want to help test these fixes, enable the proposed repository (make sure you're familiar with this because the proposed repository may cause instability!), then follow the instructions in the bug description, and post your findings there. You'll need a laptop that uses an Intel+Nvidia hybrid GPU, and use the 390 Nvidia driver to test this.

It's important to note that these fixes are for GDM3 only. LightDM and SDDM still needs some work and "will be made available in the next update".
