I reinstalled the plasma desktop with the fedora 28 net-install on the same bare metal machine as above. Fedora 28 has been updated to plasma 5.13.5 in updates. The above problem does not appear on fedora 28 only when I do a fully updated install on fedora 29.
The laptop is a dell 3531. Here is the output of lshw so you can see my hardware.

Actually I found the cause. Nothing to do with the power devil, but rather a bug in dbus permissions (bug #1641456). The result is exactly the same problem behavior by powerdevil.

That workaround doesn't help me. Powerdevil prints are like this: $ /usr/libexec/org_kde_powerdevil powerdevil: No outputs have backlight property powerdevil: Xrandr not supported, trying ddc, helper powerdevil: [DDCutilBrightness] compiled without DDC/CI support powerdevil: org.kde.powerdevil.discretegpuhelper.hasdualgpu failed powerdevil: Handle button events action could not check for screen configuration Using sysfs directly works fine: # echo 200 > /sys/devices/pci0000:00/0000:00:02.0/drm/card0/card0-eDP-1/intel_backlight/brightness Should create separate bug, I think. powerdevil-5.14.4-1.fc29.x86_64 |
