How to make gnome, fglrx and debian 8 friends?

Question

linux

I used to have Debian 7 installed on my laptop with the video card driver (ATI) fglrx.
I decided to install recently Debian 8. Installed, everything works fine. But the video card driver is not the same. No effects, "stripped down" gnome mode is loaded. And before it was like this on 7k, then I installed the driver and everything became normal. But with 8 it didn't work. After installing the driver and rebooting, there is just a black screen and that's it!
At the same time, I installed KDE for the experiment and it works fine. But if you select gnome at login, it won't load

For several days I was looking for solutions, I rummaged through the Internet, I tried almost everything. But the solution turned out to be ridiculously simple. You just had to install the firmware-linux-nonfree package

In short, you need to install lightdm instead of gdm/kdm and write in ~/.xsession:
export COGL_DRIVER=gl
export COGL_OVERRIDE_GL_VERSION=1.4
export COGL_RENDERER=GLX
export LD_PRELOAD=/usr/lib/x86_64-linux-gnu/fglrx/fglrx-libGL.so.1.2
gnome-session
(path to fglrx library may be different).
If anything, I haven’t tried it myself, I haven’t used video cards from AMD / ATI for a long time.

Debian 8 "Jessie"
AMD Catalyst 14.9
For support of Radeon R9 200, Radeon R7 200, Radeon HD 8000, Radeon HD 7000, Radeon HD 6000 and Radeon HD 5000 series GPUs (supported devices).
This driver is incompatible with the GNOME desktop, as it does not support the EGL interface. It is recommended to use the free radeon driver instead.
