--- Comment #3 from [email protected] --- Thanks for getting back to me. Please find the requested information below. It turns out that my original description was not entirely correct, sorry: CORRECTION TO MY REPORT: - The incorrect brightness does not result from suspend/wakeup but rather from reactivating the system (keyboard press) after the monitor had been dimmed / deactivated due to the power management. - In other words: actively choosing 'suspend' from the start menu and reactivating results in the correct brightness. Letting the monitor turn off, without suspend, and reactivating results in the incorrect brightness. - Perhaps the automatic monitor dimming is not being corrected? See attachment for my power management settings. kscreen-doctor -o Output: 1 DP-1 ddcafff0-ef1f-4925-ad45-4894cf5ae087 enabled connected priority 1 DisplayPort replication source:0 Modes: 1:3840x2160@60*! 2:3840x2160@30 3:3840x2160@30 4:3840x2160@30 5:1920x1200@60 6:1920x1080@60 7:1920x1080@60 8:1920x1080@60 9:1920x1080@60 10:1920x1080@60 11:1920x1080@50 12:1920x1080@50 13:1680x1050@60 14:1600x900@60 15:1280x1024@60 16:1440x900@60 17:1280x800@60 18:1280x720@60 19:1280x720@60 20:1280x720@60 21:1280x720@50 22:1024x768@60 23:800x600@60 24:720x576@50 25:720x576@50 26:720x480@60 27:720x480@60 28:720x480@60 29:720x480@60 30:640x480@60 31:640x480@60 32:640x480@60 33:720x400@70 Geometry: 0,0 1920x1080 Scale: 2 Rotation: 1 Overscan: 0 Vrr: incapable RgbRange: Automatic HDR: incapable Wide Color Gamut: incapable ICC profile: none Color profile source: sRGB Color power preference: prefer efficiency and performance Brightness control: supported, set to 91% and dimming to 100% DDC/CI: allowed Color resolution: automatic (10), range: [6; 12] bits per color Allow EDR: unsupported ddcutil --version ddcutil 1.4.1 Built with support for USB connected displays.
