primary monitor stays blank when I suspend and resume


I am using a Dell all-in-one with a 2nd monitor attached. Arch linux and KDE. Everything was working great. I updated my packages two days ago and now when I put the computer to sleep the Dell monitor does not come back on when I resume by moving the mouse. I am able to bring it back by various methods: I can log out and back in, switch users, change screen resolution, or, switch to unified output.

If anyone knows how to fix the problem I would greatly appreciate the help. Or if someone knows a bash command to bring back the display after sleeping that would be helpful as well. Thank you.

and xrandr to set resolution autmaticaly when mouse is moved..

thanks

Thanks, yooy, for your response. xrandr helps. I don't need to detect mouse movements. I just enter the command manually on the monitor that turns on.
