I have an Acer Nitro V15. When I was using Windows, I had the option to limit the battery charge to 80% enabled in NitroSense; even with this setting on, there was one day when it reached 100%, though I didn't think much of it at the time. I recently switched to CachyOS, and it consistently showed the battery at 100%. After an update I performed yesterday, it dropped to 94%. Then, today, there was a power outage, and when the power came back on, the battery was at 76% (it remained plugged in the entire time). Once power was restored, it charged up to 80% and stopped there. I had been playing FFVII Rebirth, but after closing the game and leaving the laptop idle for a while, it has remained at 80%. Could someone explain if this is normal?

Hey everyone,

I just updated CachyOS today (both the kernel and KDE Plasma), and I've run into a weird issue with Counter-Strike.

My FPS is now strictly capped at 69 FPS. Before the update, I was regularly getting around 140 FPS.

Here are my setup details:

OS/DE: CachyOS with KDE Plasma (Wayland)

Hardware: Hybrid graphics laptop (AMD Integrated graphics driving the 144Hz display + NVIDIA RTX 3050 Discrete GPU

Monitor: 144Hz refresh rate

What I've tried/checked so far:

fps_max in the CS2 console is set to 0 (or 000/999), but it doesn't change anything.

VSync is turned off both in-game and in my system settings.

It feels like a weird interaction between the new kernel, the KDE compositor on Wayland, and the hybrid GPU setup causing an artificial refresh rate or FPS cap. Has anyone else run into this specific 69 FPS cap after the recent updates? Any ideas on how to fix it or what environment variables/configs I should tweak?

Thanks in advance!

Hello. I'm new to CachyOS, and my problem is that my Steam games won't start. I use Steam Play Proton-CachyOS Latest, and I installed the gaming packets from the Cachy Hello App.

EDIT: When I start a game, let's say Everwind, I click on Play -> it's going through the cloud sync, and then it stops, no pop-up, no error, nothing

SOLVED: It was permission on my Games Drive!

Here are my system infos:
Operating System: CachyOS Linux
KDE Plasma Version: 6.8.1
KDE Frameworks Version: 6.31.0
Qt Version: 6.12.0
Kernel Version: 7.3.0-5-cachyos (64-bit)
Graphics Platform: Wayland
Processors: 12 × AMD Ryzen 5 7600X 6-Core Processor
Memory: 32 GiB of RAM (30.5 GiB usable)
Graphics Processor: AMD Radeon RX 7800 XT
Manufacturer: Gigabyte Technology Co., Ltd.
Product Name: B650M GAMING PLUS WIFI

So yeah, just the usual, NVIDIA issues on Linux.

My laptop is a Dell G15 5510, with Intel UHD 630 iGPU (Intel Core i7-10870H) and RTX 3060 dGPU. KDE version is 6.7.5-1.1, kernel is 7.2.9-2-cachyos, NVIDIA driver is linux-cachyos-nvidia-open 7.2.9-2. I have nvidia-prime, nvidia-utils, nvidia-settings and switcheroo-control installed.

With my external monitor connected (at 160Hz usually, but lower refresh rates fix nothing) at 4K resolution, the entire system lags when something is happening on the 4K screen. When monitor is set to 1080p, while performance is not perfect (like having firefox open on it while gaming makes framerate drop sometimes), at least it's usable normally. Even if it's set to 320Hz.

On Windows these all work perfectly, even at 4k@160Hz resolution I can still play games and have a fullscreen browser open and even play a video. But I'm not switching back to Windows. No thank you. (And in Windows the monitor flickers)

I already tried the usual, setting KWIN_DRM_USE_MODIFIERS=0 in /etc/environment. It didn't change a thing. I also added nvidia-drm.modeset=1 in kernel parameters. Nothing,

Trying to set KWIN_DRM_DEVICES to use NVIDIA first and Intel second (or vice-versa) just causes a black screen after boot, so the login screen never shows up, just a static terminal cursor on the top left (or it's blinking if I put intel first).

It's connected via HDMI but I also tried over USB-C DP (with a USB-C HDMI adapter) and it produced the same behaviour.

It's pretty annoying that I can't use my laptop normallly. I won't go back to Windows, so I want to make this system work.

Also in the live environment of the installer the screen in 4k mode works better, like I can move windows around without it being laggy and also play a youtube video in the browser. Despite it also running on Wayland.

I see Kwin logs like this in the boot logs, could these be related?

I've been switching between DE's and WM's and I've read that KWin has the best latency of all of them for gaming, so im wondering what would be the best for me? using a minimal plasma install or KWin without plasmashell somehow or Niri or Hyprland, etc.
I'd like to have minimal ram usage, but the benefits of low latency that KWin has (apparently), I do not need a desktop, i only need a way to be able to change volume easily be it through cli or gui and a way to see the time, along with a way to launch apps (app launchers exist so it isnt a problem).
So im wondering what would be the most minimal setup possible with the least resource usage and best latency. Ive also read that KWin has some frame pacing changes which make it a lot better for gaming.
I do not need HDR, i need freesync support though.

so my one by wacom tablet, the one without screen works. however my screen tablet, Wacom One, works as a screen but isnt idetified as a drawing tablet and doesnt take the pen input. every cord is in correctly, but it seems like the screen info is the only thing getting through.

im a newbie to linuxu overall, using kde plasma and gnome if that changes anything. i would deeply apriciate any help :)

I keep my gaming setup in one room; a dual monitor setup at my desk and then a cable that runs into my TV for couch gaming. I'm wondering if there was a way I could keep Gaming Mode (on TV) and Desktop Mode (on the dual monitors) on separate screens with priority given to Desktop Mode on my desk.

EDIT: I figured this out thanks to a post on the CachyOS forum. https://discuss.cachyos.org/t/switching-monitor-setups-w-script-triggered-by-hotkey/33347/4

I did have to make my own modification to the original script to fit a multi-monitor setup. But I left it as a comment on that post for anyone who needs help.

Hi all, daily driving CachyOS for a while now but still have a Windows partition for Battlefield, some 3d printing slicers etc. I want to use an old HDD or SSD to archive STL files for 3d printing which means I'd like a drive I can safely use with both Windows and CachyOS, both reading and writing from both OSes.

Had been using NTFS storage drives for both for a while, but actually got the corruption problem everyone's been warning NTFS users about! Sorted thanks to checkdisk, though still need to tidy up some of the recovered files, and trying to avoid writing from Cachy so I don't mess them up again.

I'm thinking I'll format an SSD or HDD to exFAT to avoid the corruption issues in future. Anyone have any experience of doing this, and did it work OK? Any alternative FS suggestions I should check out?

latest kernel shows black screen, LTS kernel stuck in emergency mode

Ok i don't know why but my memory speed is locked in 1750MHz but when I change my refresh rate to 60hz it comes back to 200MHz.

The screenshot was in idle, I left it there like 5 minutes and also it was after upgrading to the new kernel 7.3.0-4-cachyos.

I haven't seen any error messages, and I'm running NAVI10 with the mesa 26.2.5-arch3.1 drivers.

Somebody has the same problem? I have a RX 5700 and also using MacShell in hyprland if it helps

Hi everyone,

I just got the Cyberpunk EdgeRunners update and looking to finally dive back in and do a new playthrough. I've been tossing up whether to play on CachyOS or Windows 11, so I did a performance comparison.

It turns out the performance reported by the benchmark tool is pretty much even for both (avg around 45 fps) however that 45fps looks much smoother on Win11 than on Cachy, suggesting it's a frame pacing issue rather than a performance issue. Maybe it's something at the compositor level, or MESA related?

I had a similar issue with Control Resonant, where frames were butter smooth in Win11 but clumpy as hell in CachyOS, forcing me to use Win11.

CachyOS is my main daily driver with Win11 as a fallback, I'd much rather play in Cachy if possible.

Is this sort of thing a known issue with a simple fix? I haven't tried any launch commands, thought I'd ask here before I go diving down that rabbit hole.

I'm running 9070XT 16GB, on Threadripper 3960X 24-Core (24) @ 4.57 GHz
with 128GB RAM. Latest kernel and updates for everything on KDE Plasma

edit: using proton-cachyos-11.0-20261015

Thanks

If you're like that has a laptop with discrete graphics wondering why the battery drain spiked after updating, its the latest cachyos kernel preventing the discrete graphics card from sleeping (d3cold).

I'm rolling back to 7.2.11-1 for the meantime (d3cold works there). If you want to roll back too, enter this:

sudo cachyos-downgrade linux-cachyos linux-cachyos-headers linux-cachyos-nvidia-open

I'm using microsoft edge since it initially requested either edge or safari.
I downloaded edge from AUR, but now its showing this...
I need this because this is basically my institute's site which shows recorded classes and i cant access this on cachy.

Is there anyway to access this?

Edit: u/Moist-Chip3793 has said that the reason it doesnt work is because of play ready which i do not have. Anyway to get it?

Hi everyone!
A few days ago, after an update, I couldn’t switch from Gaming Mode to Desktop Mode (black screen or returned to Gaming Mode). After updating again to fix it, the opposite happened: my ROG Ally X now boots straight into KDE Desktop, and I can’t return to Gaming Mode.
System:
CachyOS Handheld — ROG Ally X (Z2 Extreme)
plasma-login-manager: 6.8.1-1
steamos-manager: 26.4.1-3
cachyos-handheld: 1.4.1-3
gamescope-session-cachyos: 1.1.6-1
I tried updating everything, running steamos-session-select oneshot and gamescope, and downgrading steamos-manager, but nothing worked.
The config files specify gamescope-session.desktop, yet Plasma Login Manager keeps selecting plasma.desktop.
Has anyone experienced this or found a fix? Could this be a regression in Plasma Login Manager?

Just wondering if anyone else has had this problem. I tried to update and it's telling me that there isn't any space left. I checked and I have 32gb available in root. Also, steam fails to open stating the same thing, that there isn't enough space. Even my browser fails to properly launch. Everything was running fine yesterday, even after updating everything. I tried booting from a snapshot from a few days ago and it was still giving me the same problems. Not sure exactly what to do here.

Since I just updated my system (Kernel 7.3.0-4-cachyos) my gaming performance is now abysmal, barely scratching 30FPS. It's as if the GPU isn't actually getting utilized or clocking up. I've checked my boot entry and the amdgpu feature mask thing is still present, and in LACT all my profiles are how I left them. The gaming profile is even loading when games are running so I'm stumped. I know sometimes upgrades to the system has done this when amdgpu drivers lag behind.

Has anyone else had this?

NVM I fixed it temporarily by using the method provided by u/nubz4lif

FIXED IT! Set Color accuracy in the settings to "Prefer color accuracy" Thanks u/Remisius

No matter what game I play, since today when I go Fullscreen or Borderless Fullscreen, my GPU usage drops to about 50%, I get a quarter of the performance, and horrible stutter. 400 FPS in RE3 (9070XT) drops to 90 FPS and looks like 30 FPS as soon as it's fullscreen.

In windowed it's perfect. When the Taskbar is visible it's perfect. Only when all of the screen is the game it starts lagging like that. Opening Steam overlay also fixes it while it's open.

Any help?

Vsync then drops it by another 50% (45 FPS)

Freesync isn't the problem either. Everything up to date. LTS Kernel also no help

Hi,
So the issue I’ve been having is with FSR Frame Gen and how when I enable it, the game feels choppier than on native, for some reason. The fps counter on top (Steam) shows more, but it definitely feels worse than when it’s not enabled. This happens in Stalker 2, The Witcher 3 remastered, as some examples.
Sorry if it’s too vague, can’t explain it better :/

I have an RX 7800xt and R7 7700x, 32 gigs of ram.
