Public bug reported:
There is a popular third-party backlight driver for Nvidia GPUs that are
not supported by the manufacturers backlight driver, known as nvidiabl
(or nvidia_backlight). See https://github.com/guillaumezin/nvidiabl for
more information. This is not the same driver as nv_backlight.
In order for this driver to be recognized by the brightness applet,
nvidia_backlight needs to be added to the top of the vendor array in
gsd-backlight-helper so that it looks like this:
/* available kernel interfaces in priority order */
static const gchar *backlight_interfaces[] = {
"nvidia_backlight",
"nv_backlight",
"asus_laptop",
"toshiba",
"eeepc",
"thinkpad_screen",
"acpi_video1",
"mbp_backlight",
"acpi_video0",
"fujitsu-laptop",
"sony",
"samsung",
NULL,
};
nvidia_backlight needs to be placed at the top of the list because the
non-functioning vendor module (sony, in my case) is still present in
/sys/class/backlight, so nvidia_backlight needs to be recognized before
sony.
