Package: nvidia-legacy-340xx-driver
Version: 340.108-17
Followup-For: Bug #1029681

Thank you for the clarifications. No offence, but as you described it, this is
practically "planned obsolescence in the opensouce world". Ok, the 340 driver
is old and it does not have a libglx. But its functionality is provided by its
libgl, so why can't we make a symlink of that libgl for libglx?
Also, why should I have any mesa lib installed since I do not use mesa for my
gpus needs?

About libglx.
The 390 is the oldest supported driver that does have libglx, so one could
upgrade its gpu to one that supported by 390. The problem is that nvidia
gt710/730, the lowest end gpu supported by it and has been around for ~10 years
now, costs 50+ euros new, which is unacceptable for a low end hardware of that
age!

Nouveau on the other hand is trash and with its devs focusing mostly on support
for newer cards (on which someone has to be crazy to use nouveau because it
lacks powersaving abilities), I will be long gone before it fully supports any
card that the legacy drivers do for years now. The word "lacking" is too little
to describe nouveau compared to nvidia.

And yes, I consider powersaving to be a very important feature of a driver. I
owned an ati 3850 back in the days of fglrx, which was the worst driver ever.
Back then, debian "had to" update xorg to a new version which was incompatible
with fglrx. That left me with radeon as the only option for the card, which was
at a very early stage and could not do powersaving at that time, so it simply
died ~2 months later from heat issues. I switched to nvidia, with the nvidia as
a driver, and I never looked back since.

To sum up, all this makes it a lose-lose situation for nvidia 340 users :(
