also the output of
inxi -G gives me the idea the nvidia drivers are not installed corectly even after re installing them completly

Seems so. I haven’t used manjaro so I don’t know what it needs to get the Nvidia drivers working.

i see if i can get the driver working tomorow (it is geting realy late here)

Sorry for the late reply, must have missed the notification.

Seem likely that it is the nvidia driver kernel module. It’s been a while since I have had an issue with this, and not on an arch based system.

sudo dkms status should give you the status of addon kernel modules. sudo lsmod gives you the modules that are in the kernel. The nvidia non-free driver module is just called nvidia
