Video BIOS
The driver cannot load the firmware nvidia/gm204/fecs_inst.bin.
Xorg won't load the nouveau driver because Unknown chipset: NV124.
The backlight does not work.
The following commands have no affect on the brightness:
echo 2 |sudo tee /sys/class/backlight/acpi_video0/brightness
echo 10 |sudo tee /sys/class/backlight/acpi_video0/brightness
Brightness works with the proprietary nvidia driver.
If mmiotrace logs are beneficial, I will add them.</pre>
