Dear Maintainer,

I'm running the latest release of Debian 10. I'm using KDE with nvidia-
legacy-340xx driver. I'm using SDDM as a display manager. I have two users on
my PC.

When I start the 1st graphical session of any of my users, the Xorg uses the
nvidia driver. But when I start the second user graphical session, for that
session Xorg uses the nouveau driver istaed of the nvidia one.

So if I'm running two graphical sessions at the same time, the second Xorg
instance loads nouveau driver.

I tried to switch to ligthd display manager but it didn't change anything.

To overcome it, I made an xorg.conf file where I define Xorg to use nvidia
driver.
