I just installed Antergos with Cinnamon desktop on my laptop Thinkpad T450s (integrated intel gpu only). I used the default screensaver setting. I also set user’s password and enable screen lock when screen saver turns on.
After the screen get turned off due to inactivity, for some minutes (I don’t remember how long), I pressed any key to turn on the screen again, then I saw the screen gets flickered. Here are the recorded videos to show how the flickering looks like:
Sometimes I can fix the condition by pressing Start + D shortcut (show desktop) multiple times, but sometimes it doesn’t work, so I have to restart the machine.
Before, I have used linux mint + cinnamon and fedora + cinnamon, never see this issue.
Any clue what caused this and how to prevent or solve this issue?
