I recently replaced Antergos with Ubuntu MATE on my Asus UX31E. It looks absolutely phenomenal on this particular machine, however I’ve noticed one odd quirk about it. On battery I have the Power Management set to put the display to sleep after 1 minute and the computer to sleep after 10. However, it seems that the screen will randomly wake up and display the the login screen, as opposed to remaining asleep. I’ve never seen this particular bug before on a distro and was wondering if anyone else had encountered it.
try running the fixes using Welcome, see the update guide for more info as there might be something missing on your system?:
