Hello, actually I use a Lenovo Y510P for work and have a GPU Nvidia, GeForce GT 755M. This Graphichcard is alive, when tried with Windows, all run ok, but since change to Linux never works, specially with Ubuntu.
I tried installa with GUI and terminal, but not lucky.
I rebooted thousend times and no have result.
just I had this return with “nvidia-smi” : “No devices were found”
Somebody can help me with this trouble?

Please do a bios update to check if that resolves it.

Yes, it’s in offload aka on-demand mode now.
If you want everything to run on the nvidia gpu, run
sudo prime-select nvidia

Please set kernel parameter
if that doesn’t work, try the opposite, leave the parameter on 0 but disable the systemd units nvidia-suspend, nvidia-resume and nvidia-hibernate
