How is multi-monitor on linux?

I’m considering buying second small touchscreen monitor, but I’ve been only ever running single monitor setup. How much hassle would it be? Is it possible to make mouse captive to primary monitor, and operate this secondary only as touch? Would running screens at different resolutions be a big problem?
Running KDE on Wayland, AMD graphics.

FMEEE,

I had small issues with Wayland so I switched to X but I think DP to HDMI and after that HDMI to VGA makes problems with anything.

olafurp,

No issues whatsoever. Recommend Wayland since you’ll probably want fractional scaling

possiblylinux127,

If you stick with Wayland it will not be a problem. X will technically work but the touch screen input will likely be broken and the text will be blurry or to small.

ursakhiin,

I’m using 3 monitors (one laptop and 2 desktop) fine on Gnome 3 with Wayland and integrated graphics. Minimal extra steps that were all Gnome related with a vertical monitor, so may not be an issue in KDE.

BoastfulDaedra,

Multiple monitors pretty much just work. Wacom-type integration is just as immediate. I don’t foresee any serious issues here, but do report back.

CJOtheReal,

Works good on mine don’t know about Wayland.

Only problem might come with resolution if the screen is a very unique size.

possiblylinux127,

Wayland will make it easier

CJOtheReal,

Than it’s good.

GreyFalcon,

try it. let us know. from dude with 3 mismatched screens. sony huge screen thru sony strdn1080, and a 27 dell landscape and a dell 29 portrait. clustered to watch f1 with miltiviewer.

Mechanize,

I used KDE with X11, an AMD card, and two different sized monitors for the longest time without any issues. It’s pretty plug and play.

With Wayland I did try months ago and it just worked™, but I don’t have a long experience with it.

Unfortunately, I’ve no direct experience with the touch integration.
