I’m using Manjaro KDE with X11 and I have dGPU as well as iGPU. I have installed the
video-hybrid-intel-nvidia-prime driver. My monitor is connected to the iGPU and I’m using the dGPU (nvidia) only for processing (CUDA).
Now, I’m trying to use GWE (GreenWithEnvy) and apparently, it requires enabling coolbits before I can make any changes to the GPU settings. Reading online as well as here on this forum, I could not learn how to do it for a case like mine. Other distributions are applying their changes to the
/etc/X11/xorg.conf which does not exist on Majnaro. And while I can understand (and appreciate) the replacement approach in Manjaro (i.e. using multiple files instead) but I cannot find where I need to make a change or the change to make.
I have tried the following command which is apparently not designed to be used in Manjaro:
$ sudo nvidia-xconfig --cool-bits=28
It creates the
/etc/X11/xorg.conf file but then the system won’t boot. I’m assuming it’s messing with the rest of hardware settings. I also see other people asking very similar questions, but it seems not an exact match to my needs, i.e. using iGPU for display and dGPU for processing.
I appreciate it if someone could please help learn how to enable coolbits for my dGPU. Here are some info one my machine:
