Please ensure that the NVIDIA device files (/dev/nvidia*) exist, and that user 118 has read and write permissions for those files. The point is that I don't have any nvidia folder in /dev but somehow graphic card works. I only have there three files: nvidia-uvm, nvidia0, nvidiactl. All have 0 B size. ** Attachment added: "Xorg.0.log.txt" https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers/+bug/1611635/+attachment/5156085/+files/Xorg.0.log.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1611635 Title: Failed to query NVIDIA devices.
