After upgrade to 15.3 using dvd method, the screen resolution is not 1920x1080 and no desktop adjustments can be made. I upgraded with nvidia proprietary drivers installed. Prior to upgrade system was at full resolution (1920x1080).
After upgrade, I did a zypper up that installed updated nvidia drivers (4) files. System is still at 1024x768 by the mate desktop display module.
Nvidia-settings gui says nvidia driver is not loaded. BUT, Yast hardware says driver is nvidia (not nouveau).
Need some insights as to how to proceed.
