Thinkpad T490 GeForce MX250 driver problems

Hey guys,

on my Thinkpad T490 with GeForce MX250 I installed the nvidia driver 430.50 via nomodeset 3. Everything worked fine, the driver seems to work:

When I run nvidia-settings, I get:

nvidia-settings

ERROR: Unable to load info from any available system


The same for nvidia-xconfig. My applications do not recognize the nvidia-driver (e.g. blender, UE4 engine). Nouveau is blacklisted.

Do you have any suggestions on how I can make my driver work? The same procedure worked on my desktop-pc with tumbleweed and GeForce 2060 without problems.

Thx, reiti

solved via prime-select nvidia :wink:
