Hello, I cant seem to find any upto date info on this topic and all the old threads seem to suggest that these features do not work well on linux.
I am looking to get a 144hz monitor that is at least 2k in resolution. I have an Nvidia graphics card and KDE Plasma. I want to run two monitors and the 2nd monitors is 60hz and 1080p. Would this cause issues? Is there anything I need to consider when looking for a monitor?
You will most likely have to run wayland to get the most out of your new monitor (in a dual monitor setup), other than that should work just fine.
If they want VRR they’ll have to use X11 since the Nvidia driver doesn’t support gsync on wayland. This also means they’ll likely be stuck with tearing on the lower refresh rate monitor.
If they use X itll be a removed and a half to get the higher refresh monitor to work with the lower refresh properly, I would rather forgo gsync than deal with that (as I have on my setup, running hyprland with my nvidia card with two 1080 asus monitors, one running 144hz).
On my PC at home I’m running KDE Plasma on OpenSUSE Tumbleweed with two monitors: 1440p 240 Hz, 4k 60 Hz. Both are connected via displayport to an RTX2080. It works perfectly fine for me.
A while back, I used Linux Mint on the same system and it was a headache, where it would sometimes boot to a blank screen and I would have to restart a random number of times before it would work. I never did figure out the underlying cause, it just went away when I changed distros for other reasons…
Are you using wayland? As far as I’m aware X11 can’t handle different refresh rates for different monitors so it defaults to the lower one.
Chiming in to say #Wayland is what resolved this issue for me. I had to switch from Linux Mint Cinnamon to #EndeavourOS + #GNOME and I’m much happier with my setup now.
I have two monitors (2K, 144hz, DP) and a TV (4K, 60hz, HDMI) and it ran fine on Plasma. I used X11, because my 2060 was causing issues with Wayland.
How did you deal with scaling with 2 different resolutions on X? I never managed to get it working quite properly, the closest I got was running some xrandr scale commands on login.
I am currently using a high refresh rate monitor with Nvidia + Wayland + KDE Plasma and it works out of the box without any setup 👍
Same for me with my two monitors 1440x2560p 144Hz & 2560x1440p 165 Hz.
I got my bootup scrolling text to only display on the main monitor, but can’t get the boot down text to stop displaying on both (sideways on the vertical one). Anyone got any tips for that (besides just turn the monitor off 😂)?
I use Arch btw
