Hello, I recently got myself a Framework 13, and I am really liking it so far! I have one gripe though, I noticed that occasionally the screen blinks. So far I can tell a couple of things, when it blinks it seems to drop to the lowest possible brightness without turning off the display (and I even think it’s doing it using some type of backlight control, as I can’t be certain, but I think I saw the brightness percent in my Waybar drop to 0% when it flashed). When it flashes, it is for maybe 1/4 of a second. I checked dmesg right after it did it, and so far every time I’ve noticed that within a couple seconds (if not right on the dot) of when it flashed, that the following gets logged.
[10256.662908] usb 1-4: reset full-speed USB device number 2 using xhci_hcd
[10256.954057] usb 1-4: reset full-speed USB device number 2 using xhci_hcd
Okay, possibly found the cause of the issue. It flashed again and I immediately went to gnome logs and caught this. You can see it setting the brightness to 1 and then back to 5%…
According to gnome logs, brightnessctl is sending the “Updated device” message and is the thing doing the brightness changes. This may not be a Framework issue after all and maybe just a AMDGPU/brightnessctl one?
Okay I found the source of the problem, Hypridle my idle daemon is telling it to happen, sorry for any inconvenience. I need to still figure out why its calling for that to happen, but I can tell that is the cause thanks to gnome logs.
Okay so I lied. It just so happened that one time is when my idle timer was going off. It has happened a couple more times… I’m still seeing that USB reset happening at about the same time though. (I’m unsure how to remove RESOLVED from the title, it isn’t letting me edit it). If anyone has any help that would be great!
