I recently install debian 9 with kde/plasms5 and try to get my graphic card working :
Code: Select all
3D controller: NVIDIA Corporation GM107M [GeForce GTX 860M] (rev a2)
Code: Select all
VGA compatible controller: Intel Corporation 4th Gen Core Processor Integrated Graphics Controller (rev 06) (prog-if 00 [VGA controller])
1) nouveau or nvidia-driver?
I decide to keep the "nouveau" driver install, after some search it seems that my card is supported. but I don't found any benchmark or performence information to know if my graphic card is well-supported
2) start my GPU
I don't remenber if I installed it or if it come with "nouveau", but I got the package :
bbswitch-dkms
But I don't know if it get my card running
I install "primus/primusrun" in place of optirun
but I got an error while trying running it :
Code: Select all
sudo primusrun blender

3) monitoring the GPU
jI also try to launch a game, seems working, but with a lot of lag,
does the "nouveau" driver supported my card not enough?
or my gpu is not start?
So, is there some programm to monitor gpu usage or just a command to see if my card is started?
I found nvidia-smi, but I fear to install it and break "nouveau"
Thank you for attention,
David,
