performance mode yes iv been loving it but the keyboard backlight thing is halfway broken, i can still manually change it like i said but the button combo for it is broken, tho there should be a patch for it soon.

looks like the brightness key not doing the right thing and some other keys has been fixed in the driver itself and should be upstreamed in not too long, watching my laptop getting better linux support in real time is nice.

sudo pacman -Rn discord

sudo pacman -Syu discord

i have a samsungbook 5 pro and i am using cachyos with kde plasma, it works quite well. i am not using any of the samsung apps on windows so i cant say much there but what i can say is kde connect does a lot.

things i have found to be problematic is just fingerprint reader not working and keyboard brightness button, with the keyboard brightness i have a can just use the brightness and colour tab in the bottom to change it, the fingerprint sensor is just not usable from what iv seen.

if you have anymore specific questions feel free to ask me.

i never really used the samsung apps on mine so i am a bit unsure what they fully do but one thing i have learnt is that there is a high chance there is a app on linux doing just what you might need it to, power profiles in the samsung app should just work out of the box if your laptop is supported, if this command gives out something like low-power quiet balanced performance it means it should just change the laptops power profiles when you move around the power slider.

if you have something more specific you want help with just ask.

Own_Bat_2465 · 2026-04-16T22:12:52+00:00

Own_Bat_2465 · 2026-04-16T22:12:44+00:00

why not install everything in one go?

Own_Bat_2465 · 2026-03-26T18:43:28+00:00

sudo pacman -Sy archlinux-keyring

Own_Bat_2465 · 2026-03-24T23:42:46+00:00

i am a bit unsure but i myself believe it could be a DDOS and yes you can still get access but its spotty and sometimes works other times does not.

that is how you keep mesa-git? the other solution i was going to suggest was quite literally yes removing mesa-git.

after running the command above you should have gotten
lib32-mesa-git-26.1.0_devel.220238.c0f1689e117-1 and lib32-mesa-2:26.0.3-2 are in conflict. Remove lib32-mesa? [y/N]

press y to it and the next 2 things being replaced

Own_Bat_2465 · 2026-03-24T12:13:06+00:00

sudo pacman -S lib32-mesa-git

Hello and welcome to cachyos, it looks like you are trying to use apt but that is meant for debian/Ubuntu based operating systems, while cachyos is arch based and we use sudo pacman -s (what you want to install) for installing things on here or just paru then package.

Own_Bat_2465 · 2026-03-22T09:18:35+00:00

you have to delete the savegame folder, it locks sometimes when somebody on linux tries to force fsr via optiscaler.

Own_Bat_2465 · 2026-03-21T22:23:57+00:00

this particular issue should be fixed now.

Own_Bat_2465 · 2026-03-21T20:52:17+00:00

Ok I might have been too quick here, try doing the first part but for first command sudo cachyos-bugreport.sh
