Weird bug in brightness between reboots
I have installed Deepin 15.11 and run some updates and reboot. Suddenly the brightness went dim. I tried to increase brightness with key and it set to max but still the screen was dim. The only fix I could find is here such putting the system into suspense and login back again. As in the mentioned link, the OP posted the issue using 15.7 but the issue still persists on 15.11. Seems like an unnoticed bug ?
