After fixing the "System runs in low graphic mode"-error, the resolution of my screen changed to 640x480. Obviously, this is not my native resolution.
I cannot set it to the native resolution (1366 x 768) for some reason, since there is no other resolution shown in the Monitor Settings. Arandr also does not show 1366x768 as a possible resolution.
My laptop is a Samsung R519 with standard resolution 1366x768, with an Intel graphic card.
Does anyone have an idea how to solve my problem? I hope I explained it clear enough (if there is some missing info, please let me know)
