Is there a way to test this patch with the 418 driver? I have an RTX

@Alberto, with prime-select intel as well as with bbswitch off, powertop

I observed the same behaviour as Adrian S..
Selecting Intel keeps the Nvidia card powered and the fan spinning.

I can confirm that installing nvidia-390 through the Ubuntu driver dialog, and

GPU: NVIDIA Corporation GF119M [GeForce 610M] (rev a1) - [GeForce
610M/PCIe/SSE2]
OS: 18.04 x64
Test update, works perfectly. Switching between Intel & NVIDIA
@Alberto I was assuming that this should also work with sddm (on
Kubuntu), but apparently not out of the box. Is there already something
to test there?

I don't know if they updated the 396 packages to reflect my changes in
nvidia-390.

Is this fix related to nvidia-390 only or will nvidia-396 from graphics-
drivers/ppa benefit from it as well?

@ubname: installing the meta-package worked here, but you can install
the single packages manually:
sudo apt install libnvidia-gl-390/bionic-proposed libnvidia-compute-390
/bionic-proposed libnvidia-decode-390/bionic-proposed libnvidia-
encode-390/bionic-proposed
I've try to test without success, also following Alberto's procedure #40
packages have dependencies problems:
Versione "390.77-0ubuntu0.18.04.1" (Ubuntu:18.04/bionic-proposed [amd64])
selezionata per "nvidia-driver-390"
Versione "390.77-0ubuntu0.18.04.1" (Ubuntu:18.04/bionic-proposed [amd64])
@Thomas: sorry but support for Lightdm and SDDM will be available in the
next update.
