--- Comment #2 from Bruce Guenter (br...@untroubled.org) --- Adding acpi_backlight=nvidia_wmi_ec to the kernel command line works around the problem for me. With this option, I am able to control the backlight both with and without the proprietary nvidia module loaded. So, that gives us a workaround, though having this be auto-detected would be preferable. -- You may reply to this email to add a comment.
