Hi - I'm not able to duplicate this on my Thinkpad X390 with Plasma 6.0.2 / Wayland on Neon. Any more details on how this might be reliably reproduced would be appreciated. Thanks, Nick (In reply to Nick from comment #1) > Hi - I'm not able to duplicate this on my Thinkpad X390 with Plasma 6.0.2 / > Wayland on Neon.

I'm using a framework 13 with a Intel i7-1360P, As for reproducing I tested after a reboot and also on X11 and it still occurs. I would just start from 100% brightness and scroll to minimum and it almost always would have an incorrect brightness or value. I can record a video to demonstrate, what's the best way to link a video here? Hey - I just duplicated it! Your instructions were spot-on. Just to confirm: I'm on a Thinkpad X390 / Neon / Wayland / Intel graphics. Hover mouse over the brightness system tray icon. Use two-finger scroll on touchpad to increase brightness to 100% Quickly swipe down with two fingers and see the brightness indicate 0% However, at this point the screen is not completely dim. Confirm this by using the laptop brightness down button. One press of this and the screen goes immediately dark (i.e. 0% brightness). So it seems Plasma is reacting quickly to a fast scroll from the user, but the physical backlight is not keeping up. Thanks for reporting this bug. Marking as confirmed. Thanks, Nick.

Marking as confirmed. Thanks, Nick. Great! I also reproduced on my other laptop running on Nvidia graphics. I followed instructions for running Nvidia only but I'm not sure if having integrated Intel graphics affects it 😅 *** This bug has been marked as a duplicate of bug 481003 *** |
