Hello Ubuntu masters,
Greetings!
I'm having trouble with my ubuntu 20.04 running on dell xps 13 9310. The brightness adjustment seem to be not working. I already modified the grub file with the following line but still not working.
I'd like to check with you guys if you already encountered this case. If so, can you share some info on how to get rid with this? Thanks in advance!
Code:GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi=Linux acpi_backlight=vendor" GRUB_CMDLINE_LINUX=""
