I can hear the sounds from the movie that smplayer played.

1. Please wrap shell output in "code" tags
2. Please do not bump, mend your posts by editing them (link in lower right corner of the posts)
3. Provide some actually relevant information, namely:
- the used display server (wayland/xorg)
- your optimus configuration
- a better description of the behavior: does it happen immediately or after some time, does the monitor re-activate on input (ie. whether it's dpms or the output is deactivated)

Re: qt5ct set gtk2 theme,and launch smplayer will cause shutdown monitor
I've noticed similar behaviour with qBittorent as of late. If you use QT_QPA_PLATFORMTHEME="qt5ct", it will freeze and cause graphical glitches all over desktop. However, if you use a different Qt style, like default Fusion, problems disappear. Not sure if it's a Qt bug, qt5ct bug, or bug in styleplugin, but seeing how style change helps, I'm betting on latter.
