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.

X11 vs Wayland (lemmy.ml)

I'm a seasoned Linux user, but mostly for servers and services, not really for desktop use.

I've dabbled in some desktop distros on my personal rig a few times in the past, but ultimately due to specific games, I've gone back to Windows.

I recently installed Arch and KDE. Upon initial boot I noticed it was defaulted to Wayland. Every time I would try to log in it would just go to a black screen then cycle back to the login screen. Picking X11 would bring me to the desktop.

Basic Specs:

AMD Ryzen 7 5800X 3D
nVidia RTX 4090

I have been doing some reading into this and it looks like the issue is due to the proprietary nVidia drivers, but there are solutions to work around this.

I know nothing of Wayland other than its supposed to be more secure. My question is, is it worth the time/effort to get Wayland working? I primarily use my system for gaming. X11 seems to be working just fine for me right now.

Forgive me if I'm using some of the terminology wrong, still learning.

EDIT - Selling my gpu is not an option. I knew ahead of time that AMD has superior Linux support, but the 4090's performance can't be matched by anything AMD has. Maybe next upgrade I'll go back to AMD if they have the top performer.

I would double check if you have options nvidia_drm modeset=1 in your modprobe.d. This is necessary for Wayland. I can login to KDE Wayland just fine with my 3090, but I still stick with X11 for now because of VRR and overall better input latency. The input latency issue isn't an Nvidia specific thing, although Nvidia does perform worse with Wayland than AMD in some cases.

And while you're at it add options nvidia NVreg_PreserveVideoMemoryAllocations=1 so that your GPU saves video memory when your system suspends.

This is the right answer. I can't even count the number of times people have shrugged off Wayland because Arch doesn't include this kernel parameter by default and they didn't read the Arch wiki.
