I just received a new Dell Latitude E5570 for work and installed Ubuntu Gnome on it. I quickly realized that it was only running at 1366x768, rather than the 1920x1080 it should be capable of. In the list of resolutions, it is not showing anything higher than 1366x768. I've already had to install kernel 4.7 in order to get Ubuntu running properly, so I suspect there might be some issue with the newer hardware. Is there anything I can do to find a solution?
Edit: I have tried the solution listed in the suggested duplicate, and when I try to addmode I get:
➜ ~ xrandr --addmode eDP1 1920x1080_60.00 X Error of failed request: BadMatch (invalid parameter attributes) Major opcode of failed request: 140 (RANDR) Minor opcode of failed request: 18 (RRAddOutputMode) Serial number of failed request: 47 Current serial number in output stream: 48
