I’ve used Mint cinnamon since the 17.x days ( current on mint 19.2), and as far as I can remember in cinnamon, one must use xrandr to set a refresh rate higher than 60hz. If there is an alternative or better method…PLEASE let me know as my googling keeps deadending with xrandr.
Thus my command is xrandr --output DisplayPort-0 --mode 2560x1440 --rate 144 for my particular setup.
Every boot up it works correctly. HOWEVER, more often lately when I’m alt tabbing between chrome and something else or even when I’m not and am just watching a youtube video or just reading text on a web-page, my system will randomly auto-change the stupid refresh rate from 144hz back to 60hz.
Is there a way to tell lightdm ( the default display manager in mint 19.1 and 19.2) a way to prevent this or autocorrect-instantly this problem…perhaps some type of file edit ( such as xorg when using an nvidia video card)? Or is there something else I’m missing? I’ve looked through what I think are all of the lightdm files but nothing talks about a refresh rate.
Also , unlike in Mate and possibly other desktop environments, “Display” gui menu/settings selection does not give an option to change the refresh rate. ( way to go Cinnamon developers!! It’s only been how many years without this option while Mate has had it …how long?? -_- )
This is the kind of crap that pushes me back to windows and I’m trying to stay away from Micro#$t’s data mining.
Also, It doesn’t matter for what amount time I set the delay to for the 144hz mode command or even any at all. Is there something critical I’m missing here? Please help.
