Hello all! Hoping one of you can help.
When trying to use bbswitch in Manjaro running kernel 4.20, I get the following error from primusrun:
[ERROR]Cannot access secondary GPU - error: Could not enable discrete graphics card
If I go into bumblebee.conf and set PMMethod to "none" rather than "bbswitch" and reboot, everything works fine. The secondary GPU loads up and using primusrun launches whatever I tell it to properly on the NVIDIA GPU. Setting it back to bbswitch, rebooting, and trying produces the error again.
Running without power management is obviously much less than ideal, as I'd like to make sure that when I'm doing productivity tasks, I'm not running a battery sucking GPU that is sitting idle.
I have a Dell Inspiron G5 15 with a GTX 1060 Max Q and an i7-8750H.
I searched around the forums and tried the power management blacklist and GRUB boot options, but none of those seem to work (or they render my system unbootable until I revert them).
Anyone have any ideas where I can go from here? I'd like to get bbswitch working on this thing for Steam games.
