From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Linux needs better multi-monitor support. It's better than it's ever been, but it's still janky and giving black screens on tertiary screens at times.
EDIT: It's funny how the comments are all over the place. "works for me", "it's broken on KDE but works on XFCE", "it's broken on XFCE but works on KDE", etc. I think that's a good sign there are problems with multi-monitor support.
Wayland fixes multi monitor
Its more of a Desktop thing rather than Linux. If you use the right Desktop like Plasma then you have no issues at all.
I really don't see any problems with Multi monitor, I actually have more issues with Windows 11 right now in terms of multiple Displays
I've been messing with this on and off for a few years now and I still haven't seen support for multiple monitors running at different scaling levels (like running a 4K monitor at 125% alongside a 1080p monitor at 100%). This is a feature I use in Windows on one of my setups. I hope this gets some attention soon. I run Linux on most of my machines but this problem still gets in my way on others.
Plasma on Wayland can do that I'm pretty sure, and if you don't have an Nvidia GPU Wayland is fine nowadays. Hell, even if you have an Nvidia GPU it's mostly fine nowadays.
Its very fine with Nvidia too
Okay thanks, I haven't tried Wayland on that machine (which has an Nvidia card) but I'll give it a go! Appreciate the help.
Then use Wayland, its there, its the default and KDE and Gnome should have each their own solution to this feature so you may compare them.
I've never had issues with multi monitor, what desktop are you using?
I had the reverse experience. I have had no issues with multi-monitor (OpenSUSE, nVidia driver direct from nVideas own maintained Opensuse rpms) but on Windows I'm having Windows open black, or delayed, not recognizing external display, etc. Too many variables to make proper apples to apples comparisons.
Plasma has really good multi monitor support since 5.27. Use latest versions and be happy 🙂
Plasma is probably the worst out of the few bigger DEs. If you don't replug the monitors the same way to the video card, the toolbars you have configured disappear and you cannot copy it from a different display or even make all toolbars identical on all monitors...
nvidia 😏?)
AMD
fuckedup. plasma is the worst DE, we will die all 🙂
While this is probably still true, I doubt it's a big factor when talking about mass adoption.
How many people total do you think use more than display? How many Linux users or users that would be willing to use Linux would want more than one display? I'm betting it's a lot if not most. So while it may not be a big factor it probably is a factor that applies to most. Then you add up all the other stuff that just doesn't quite work right and you lost the incentive or motivation to switch.
I'm sorry but the majority of people absolutely do not use more than one display.
I haven't had any multiple monitor problems since switching to KDE that weren't actually Nvidia driver issues. My "TV" is a third monitor on a long ass HDMI cable.
My only remaining issue is that wayland has slightly more input latency when playing games, enough that it's noticeable (or a very convincing placebo effect).
This makes it so that I have to use X11 and that I have to disable compositioning when playing games as my displays have different refresh rates. All in all, not a big problem but looking forward to be on wayland for good soon.
Indeed. I use Xfce and have to switch to Cinnamon to get a very good multi-monitor support.
Why? I am running XFCE and didn't have any problem using an external monitor.
Xfce have a hard time recognize recently plugged in monitors. I have to restart the PC with the monitors plugged in to have a 50/50 chance to make it work. Or just switch to Cinnamon and make it wok right away.
Have you tried any other distro with XFCE? I am running Gentoo and Void and both are fine.
Nope. Since Cinnamon fixes the issue, I have no plans to test with other distros 😊 But I might some day.
