--- Comment #1 from smealzr...@gmail.com --- After some further troubleshooting, I've found that the udevadm hook is the culprit, specifically when it runs this command: >sudo /usr/bin/udevadm trigger -c change /dev/dri/* It seems to trigger night light to run at full strength regardless of the device in the /dev/dri/ directory. Here is what my directory looks like: >$ ll /dev/dri >total 0 >drwxr-xr-x 3 root root 160 Sep 20 17:11 ./ >drwxr-xr-x 22 root root 4860 Sep 20 17:32 ../ >drwxr-xr-x 2 root root 140 Sep 20 17:11 by-path/ >crw-rw----+ 1 root video 226, 0 Sep 20 22:58 card0 >crw-rw----+ 1 root video 226, 1 Sep 20 22:58 card1 >crw-rw----+ 1 root video 226, 2 Sep 20 22:55 card2 >crw-rw-rw- 1 root render 226, 128 Sep 20 22:57 renderD128 >crw-rw-rw- 1 root render 226, 129 Sep 20 22:58 renderD129 Output of sudo udevadm test /dev/dri/renderD128 >$ sudo udevadm test /dev/dri/renderD128 This program is for debugging only, it does not run any program specified by a RUN key.
