I have an Alienware Aurora R11 with a RTX 2080 SUPER inside, and the GPU often falls off the bus when running Linux. A problem that’s plagued me since day one of owning this machine. Nothing is overheating, and my BIOS is up to date.
I think I may have fixed the system freezes by setting PowerMizer to “Prefer Maximum Performance,” and setting coolbits to 12 in an xorg config. However, the idle temperature of the GPU increases to about 63°C.
In an attempt to manually set the GPU fan speed with nvidia-settings, I get an error: “Failed to set new Fan Speed!”
If I set the setuid bit of “/usr/lib/Xorg” I’m no longer locked out of manually setting the GPU fan speed. I don’t feel totally comfortable with the security implications of this. Is there a way to get manual control of the GPU fan speed in nvidia-settings without setting the setuid bit of /usr/lib/Xorg"?
