I remember when I was on Ubuntu 16.04 and Ubuntu 18.04, there was that weird glitch on TeXstudio where it initiated a system shutdown signal when I just press on the power button, even for less than half a second.

And now, I don't have this problem on Xubuntu. I still don't know what were the circumstances of this glitch, but I don't think I need to bother about it for now lol
