[Solved] Suspending even though it's disabled under power manager

[kekie]

Like the title says : under "Xfce power manager" everything is set to "Never" yet the machine suspends (The screen goes black, the power button LED blinks instead of being on solidly, and I have to press the power button once to wake it up). It does this even when I am actively using it (moving the mouse, typing, etc), which is really annoying.

Linux mint XFCE (with some other window managers installed & sometimes running as they are used by some remote desktop software).

Welcome to the forum, kekie.

There are only three supported desktops in Linux Mint, Xfce, MATE, and Cinnamon. If you are running something else (which appears to be the case) then there may be interference which is causing a problem.

The system information you posted is not what we would expect to see with a Mint Xfce install. Gnome is not a supported desktop.

Kernel: 5.4.0-73-generic x86_64 bits: 64 compiler: gcc v: 9.3.0

That is a bit unusual, but maybe some of the other software you installed is a factor in how inxi reads your computer's information. Are you running the latest UEFI available for your desktop?

If you are running remote software to access the machine and generate this information, that may be why there is no renderer available. The lack of a renderer can also cause issues during suspension and resume from suspension.

I figured it out. MG was correct in pointing out that gnome could be causing the problem. It looks like the separate window managers had separate power settings. Disabling suspend in both XFCE & Gnome fixed the issue.
Thank you!
