The max I can set my resolution currently is 1024x768, but my laptop's native resolution is 1920x1080. I've always been able to set it to 1920x1080 without issue, but since I broke my video driver (I installed 'nvidia-current' which broke my display, see this thread) I haven't been able to get above the aforementioned 1024x768.
