I am currently attempting to connect a monitor to a laptop with a broken screen, the monitor works fine, however when I try to disable the primary laptop screen, or mirror the displays, using system settings,
lxrandr, ubuntu freezes, requiring a restart. Any suggestions on how I could change the displays without this freezing?
The monitor is a fujitsu siemens c15-2, and the laptop is a dell inspiron 9400, with ATI RV515 graphics. I am running Ubuntu 16.04
