I JUST INSTALED cashy os as my first linux and i already cant see anything properly its all glitchy and blurry even at installation phase it looks like really horrible camera
i think it might fix if i can change my resolution to 4096*2160 because m stuck on 1080 but every time i selected any other option from settings it just blacks out and reverts back to 1080
so
i tried a manual command to force resolutions from yt video and after all that i got this
warning RUNNING XRAND X AGAINT X WAYLAND SERVER
i am on Rog board with Ryzen cpu and nvidia 3060 so maybe i needed drivers too
i am new to Linux my 2nd day here. So pls try to give feedback in a way i understand if i did a mistake but i expected to Linux to work properly atleast before i started to break it lol
I installed kde plasma desktop env.
I looked up drivers for 3060 and it said i already had them(they clearly weren’t working tho) so i found arch command for Nvidia
This at least bumped up the resolution from 1080 to 3***x2160(i forgot the exact number in 3k) the resolution was somewhat back now the refresh rate even tho it said 60 it definitely felt 30. And now other options are GONE i ct change resolution
This is my windows resolution 4096*2160 60
I just want this
The last day has been me struggling to find solutions and tbh m tired so i came here to report this issue because i can’t seem to find any solution and i don’t think there is any because i would have found it by now
This warning occurs because you are running X11-based commands (like xrandr or xinput) while using a Wayland compositor, which only simulates X11 via Xwayland. These tools cannot directly change the resolution or input settings of your Wayland display server.
“i am on Rog board with Ryzen cpu and nvidia 3060 so maybe i needed drivers too”
This is common to think you need drivers. This is how it works in Windows. In Linux, its in the kernel or its not. If not there are packages.
There is a package you can download directly from Nvidia. Go to the site and drivers then enter your information and find the correct package. The problem is Nvidia and Wayland (which is what CachyOS is running instead of X11). But to be clear, its not a Wayland vs X11 issue of which can be debated all day of the pros and cons but its the support from Nvidia. AMD cards don’t have an issue.
3840x2160 is standard 4k resolution. What is the native resolution of your monitor? Or what model is it? I’m certainly not a monitor expert, but 4096x2160 seems like an unusual resolution. Pro video production setup or something?
Seems like you are hitting that weird bug with Nvidia cards when connecting to a TV with HDMI when using a Wayland session. You are not alone in not seeing 60Hz. But the resolution issue is a little different.
The fix is to either 1) use an x11 session with KDE (I assume you are using KDE) or 2) go into the TV’s settings for that HDMI port and try turning it off of “auto” and to “standard” or whatever is similar to that. The issue is that the link negotiated between the TV and GPU is for HDMI 1.4 which can only do 30Hz at 4k resolution. For some reason this backwards compatibility mode is being used instead of an HDMI 2.0+ link.
You can blame Nvidia, its their driver that is doing this. If you have an integrated Intel or AMD GPU you could try connecting your TV to that card and see if the link is correctly negotiated for both refresh rate and resolution. This would be a sanity test for both the compositor (kwin) and the kernel driver (iris/xe or amdgpu vs. whatever the hell Nvidia uses).
Hey, I also run a 4k Tv, mines a Tcl 75 with no problems at all. I`ve always found its best to experiment, I personally like KDE as its got HDR. Ive got an AMD 9060 right now but was running with a RTX 3060ti and both ran just fine in various flavours of Linux
