Thanks for staying with me, Fabio. Here is what I have done so far: - Removed 'acpi_backlight=vendor' from kernel boot parameters, since that fixed the problem - *sudo update-grub* - ls /sys/class/backlight/ dell_backlight (because of «Checking the kernel interfaces»). *reboot*
Nothing changed, that is: Brightness is still awkward. Do you want me to add the line back to boot parameters before trying your .debs? Should I install them all at the same time?
