NVIDIA GPU sensors now work on Arch and CachyOS
If you installed the Arch package and your NVIDIA card showed no temperature, load or power — this is why. The NVIDIA reader was listed as an optional dependency, so pacman never installed it, and TRCC quietly fell back to no GPU data. Nothing told you it was missing.
It's now a required dependency like every other, so a fresh install just works.
Already installed?
sudo pacman -Syu trcc-linuxOr if you'd rather not upgrade yet: sudo pacman -S python-nvidia-ml-py
The Trofeo Vision 9.16 can be rotated again
On the 1920×462 ultrawide panel, setting the display to 90° or 270° silently did nothing — the screen stayed landscape.
The rotation itself had been correct for two releases. The panel was simply listed as landscape-only, so the app refused the setting before it ever reached the screen. All four angles now work, matching the official app exactly.
Installing on Ubuntu / Debian actually works now
Our own one-liner was broken. dpkg reports an error when dependencies are missing, and that error caused the very next command — the one that installs those dependencies — to be skipped.
If you got a wall of "depends on … however: Package is not installed", that was us, not you.
curl -LO https://github.com/Lexonight1/thermalright-trcc-linux/releases/latest/download/trcc-linux-latest_all.deb && sudo apt install ./trcc-linux-latest_all.debNo more unplugging your cooler
Every install guide used to end with "unplug and replug the USB cable" — on a panel that usually lives inside your case, behind tempered glass.
It was never needed. The installer already applies the USB permissions, and TRCC finds your cooler on its own when it starts. Just run trcc gui. (If it isn't detected, a restart still sorts it.)
Thanks to @neecride for the logs that found both device bugs, and @developer-yl for reporting the install command instead of just working around it — it had been broken for everyone who copy-pasted it.
Both device fixes are verified against the official app's own logic, but not yet on real hardware — if you have an Arch box with an NVIDIA card, or a Trofeo Vision 9.16, I'd love to know how you get on. 🍺
