So I recently installed Ubuntu onto my Surface Pro 1, and have been running fine for about 2 days, until today I saw the screen constantly turning off, as if it were inactive for the set time and turning the screen off. I would then just have to tap the power button and it would come back on and then about 20 seconds later turn back off. This used to only happen after the system was suspended, and I would just have to restart to fix it, but now it is happening all the time and making it un usable. How can I fix this? Thanks!
