The dell_backlight interface is dysfunctional and should not be exposed for your system i.e. don't specify acpi_backlight=vendor. Also i915.i915_enable_fbc=1 is known to cause issues on your system. Thanks you for your answer. Any suggestions? Bug report for another packet? Stay with xf86-video-intel 2.21.13? Reoving acpi_backlight=vendor make the brightness control very erratic. You can use Option "backlight" "intel_backlight" to override the selection of dell_backlight. Thanks you! |
