  • “[...] Like I was daily driving fedora last year and : - fractional scaling did not work in Gnome with Wayland for X11 Apps - I still cannot use my LG C4 as a monitor in full capacity because AMD on Linux does not support HDMI 2.1 - Screen sharing was very buggy - in Slack especially - it would constantly crash the slack app during calls, ditto for camera, but even in Google meet and Chrome I've had desktop crashes - When I switched to KDE/Plasma 5 to get fractional scaling it was extremely unstable - Right now I upgraded my GPU to 9070XT - I'm still not sure if that would work on Linux yet because of driver support delay - Guitar Amp simulator software I use does not support Linux, neither does Ableton (which supposedly can run on proton but with many glitches) - The audio DAW situation was way too complicated and buggy - I spent days to get the distro functional and usable with Ardour and it would still crash constantly - I just wanted to run some amp sims :( It's just the little things and rough edges, but for example the fractional scaling stuff already improved because more apps that I use added Wayland support. [...] Not sure about the audio progress - JACK was a complete mess.”

Common LG C4 OLED problems

Issues at least two owners independently report.

  • Software & AI6 mentions

    “[...] Slack would crash when screen sharing, likewise for chrome/gmeet, camera corruption bugs. [...] Installing a DAW took days of reading audio routing docs and trying stuff out, breaking my audio several times in the process. My LG C4 cannot be used at 4k/120Hz because you cant get HDMI 2.1 on Linux/AMD. [...] Hell I never had a PC laptop that managed sleep state reliably and didn't cook the battery in the backpack randomly. [...] It is hard to justify dealing with Linux desktop and PC hardware even at a price premium, but these days Apple devices are even price competitive compared to similar windows/linux machines.”
