<p>Sir,<br>
I uninstalled and then reinstalled NVIDIA. The installed driver is
"nvidia-tesla-470-driver". For primus the following packages have
been installed:<br>
"bbswitch-dkms, bumblebee, bumblebee-status, primus"<br>
<br>
However, I had several errors:<br>
1- /etc/bumblebee/xorg.confi.d "file not found", solved by adding
empty file "10-dummy.cont"<br>
<br>
2-"Mouse and kbd not found" packages "xserver-xorg-input-mouse and
xserver-xorg-input-kbd" fixed this error.<br>
<br>
3-I also added in the "/etc/bumblebee/xorg.conf.nvidia" file the
following line: Busid="PCI:01:00:0"<br>
<br>
<br>
Now there is no error, "primusrun glxgears" and "optirun glxgears"
work fine. Unfortunately there is no video acceleration compared
to "glxgears".<br>
Here under the results under debian 12 (Bookworm) et debian 11
(Bullsyes".<br>

As you can see under Debian 11 only "optirun" has the performance
of the Nvidia GTX960M chips.<br>
primusrun has Intel GPU performance.<br>

I don't see a solution to solve those problems. Can you pass it on
to whom it may concern?<br>
Thanks<br>
