(resending because of HTML formatting) Hi, I'm on Arch Linux and upgraded from kernel 5.18.9.arch1-1 to 5.18.10.arch1-1. The brightness keys don't work as well as before. Gnome had 20 degrees of brightness, now it's 10, and Xfce went from 10 to 5. Additionally, on Gnome the brightness keys are a little slow to respond and there's a bit of a stutter. Don't know why Xfce doesn't stutter, but halving the degrees of brightness for both makes me wonder if each press is being counted twice. Reverting commit 3a0cf7ab8d in acpi_video.c and rebuilding 5.18.10.arch1-1 fixed it. The laptop is a Dell Inspiron n4010 and I use "acpi_backlight=video" to make the brightness keys work. Please let me know if there's any hardware info you need. #regzbot introduced: 3a0cf7ab8d
