Hi, Fixed for me on Lenovo T440p. See: https://bugs.kde.org/show_bug.cgi?id=323516 , comment 24 |
When changing the brightness using my Fn keys (which act weird, and seem to do some ACPI magic directly), PowerDevil doesn't pick up the brightness changes, so neither OSD shows up, nor battery monitor slider adjusts. udevadm monitor shows the events: KERNEL[3110.548241] change /devices/pci0000:00/0000:00:02.0/backlight/acpi_video0 (backlight) UDEV [3110.548567] change /devices/pci0000:00/0000:00:02.0/backlight/acpi_video0 (backlight) KERNEL[3110.548931] change /devices/pci0000:00/0000:00:02.0/backlight/acpi_video0 (backlight) UDEV [3110.549284] change /devices/pci0000:00/0000:00:02.0/backlight/acpi_video0 (backlight) xrandr knows the brightness too: BACKLIGHT: 1 (0x00000001) range: (0,10) Backlight: 1 (0x00000001) range: (0,10) Reproducible: Always
