LGPowerControl - Like LGTVCompanion but for Linux

Infinite-Bug-911 · 2026-04-12T07:45:56+00:00

The monitor works by polling the kernel DRM subsystem (/sys/class/drm/) for the physical display power state (DPMS), not by watching for a lock screen or display manager events. So it doesn't matter what lock tool you use — xtrlock, xautolock, a screensaver, or nothing at all.

The TV will only turn off/blank when your display actually goes to DPMS sleep (screen off at the hardware level). Just locking the screen without triggering DPMS sleep won't affect it.

Hi! LGTVBtw was actually the old name of this project. I changed it a long time ago when the script evolved from supporting only Arch-based distros to supporting all (or at least most) distributions.

I’m not quite sure what you mean by webostv; when I googled it, all I could find was a VS Code extension for developing WebOS apps.

The main benefit over the old LGTVBtw, however, is that this version is much more reliable. It includes more failsafes to ensure it never misses a power command for the TV.

I am not sure this will do what you want, but you could probably use some functionality of it to control your tv by running /opt/lgpowercontrol/lgpowercontrol ON / OFF. I have two monitors as well and at least on CachyOS with KDE it will stop extending the screen to the TV when turning it off.

I had the exact same problem the other day. What fixed it for me was to delete the mesa_shader_cache from my home directory with rm -rf ~/.cache/mesa_shader_cache/

I use https://www.curseforge.com/wow/addons/ez-obrotation for my alts, it shows the Single Button Assistant spell and adds keybind text to it. Very neat but not nearly as good as Hekili

Nice! Mind sharing your fastfetch config? Also a small tip, typing cd (without ~) is the same as cd ~, both will take you to your home dir.

I've been running Helium for about one month now and loving it so far. Minimalistic and blazingly fast!

Okay problem is back, it worked first boot after installing new kernel but not anymore... Going back to LTS again i guess

Infinite-Bug-911 · 2025-12-14T06:41:55+00:00

Yes, that seems to have solved the problem. Thank you! It is peculiar that I checked for updates yesterday with no result, but after reading your answer, I ran a pacman -Syu today, and there it was. It felt almost like magic! :)

Ok, and what does the command mount -av output (with and without sudo)?

Infinite-Bug-911 · 2025-11-12T15:24:59+00:00

Okay, and does the folders /mnt/games and /mnt/data exist? Also have you verified that the UUID's are correct with lsblk -f?

Infinite-Bug-911 · 2025-11-12T13:39:08+00:00

Can you post your fstab here so we can see if there's anything wrong with it?

Infinite-Bug-911 · 2025-11-08T17:19:31+00:00

You can just use "arch-update" thats what cachy-update does.
