It’s normal to require root privileges to view many system files. Here’s the relevant section

- So, for whatever reason your monitor’s EDID is reported as invalid. Did this ever work correctly (with previous nvidia drivers for example)? If so, maybe its a bug that needs reporting to NVIDIA
- Have you tried using the ‘nvidia-settings’ utility (run as root) to select the preferred resolution? If not, open a terminal, and become root with
su -
Enter your root password when prompted, then
nvidia-settings
This guide is for TwinView issues, but may still be relevant to your situation:
SDB:NVIDIA troubleshooting - openSUSE
In particular, it will assist with creating a minimal xorg.conf that can be used to coax Xorg to provide the desired resolution manually.
