When Windows 10 support ends I was planning on transitioning to Linux on my desktop. I just tried CachyOS KDE Plasma and immediately ran into two serious issues:
-
I could not figure out how to get audio to come out of my headphones. Everything is connected, and sound totally works on Windows 10 with my Audioengine D3 USB DAC, but not in CachyOS. I messed with all the system audio settings, profiles, and mute control, and nothing worked. No audio at all, not from test sound, not from browser.
-
Apparently Wayland is the name of the default/best video compositor for Linux, but it doesn't seem to support ycbcr subsampling modes. In Windows 10, I use the Nvidia-provided 4:2:0 subsampling mode with my RTX 2060 Super to get 4K120 support over HDMI to my LG C1 (genuinely hard to see the difference unless you're running a test pattern). It seems you have to use the X11 compositor in Linux to get that feature, but I've read that X11 provides a poor experience compared to Wayland.
Not to mention, my first CachyOS install attempt bugged midway through (installing from DVD disc) and I spent a lot of time unsuccessfully trying to restart the install process not realizing something was borked in that session that was preventing partitions from being formatted for the installer. So I rebooted and manually set to load the installer into RAM, and finally was able to get it to install.
Seeing my experience hasn't improved since the last time I tried Linux (Mint, a few years ago - really bad audio stuttering), now the plan has switched to sticking to W10 until software inevitably stops supporting it (Nvidia is already ending W10 game ready support this year), and then switching to W11. I'll just have to use mods to improve the usability, specifically for start menu and right click menu.
I would like to use Linux but it really disappointed me seeing all the hype on LTT's channel, only to see that it's still user experience hell. It's either "works but evil" (Windows) or "doesn't work but not evil" (Linux) and that's unfortunate.
My 2 cents:
Never, under any circumstances, use CachyOS or any other Arch-based distribution if you're a Linux newbie. Arch assumes you know your way around the system, know how to fix this or that, and which package you miss to make the sound work. It is, by all means, "move fast and break stuff".
I found Kubuntu has the same two problems I detailed but I made slightly more progress this time. The USB DAC would've likely also worked at 100% volume in CashyOS I just didn't think to try it because of my ears. I'm sure some manual config edit can fix that but I expect something basic like sound to work by default and knowing it doesn't makes me assume other basic things will be a pain in the future.
Then I actually tried subsampling in an X11 session this time, but the problem is the Night Light hue becomes green. But 4k120 at ycbcr 4:2:0 does work in principle. And the fact that this is in xorg config rather than a settings GUI, all this config text editing is so slow and sketchy for me.
