GNOME brightness controls have no effect on brightness
Hi folks,
Debian 11 on Dell M4800 Mobile Workstation with Nvidia Quadro K2100M card.
I've been using the system with full (100%) screen brightness for rather
long time. Today I wanted to reduce it and to my astonishment found
that GNOME "progressed" to the point when even this basic feature has gone.
The function keys work, the sliders move. Everything is dandy, except it
has no effect on the actual brightness, which stack at 100%. Even
setting the brightness in BIOS to 50% instead of 100% has no effect.
Google revealed a lot of complaints but so far I've not found any really
helpful suggestion. Worse, I even couldn't find any trace of this being
a bug of some sort.
Anyone can help here? I'm getting old and my eyes sore. :-(
Sorry for the rant but it looks that either GNOME folks decided they
know it best what it should be for everyone or they are so busy with
frequent "nice" GUI changes and re-designs that there is no time left
for actual functionality. Fake controls and sliders doing nothing?..
This is really climax.
Thank you,
Juan
