I use fedora on a 11ish year old laptop(It had decent specs for its time).

recently i encountered an issue while playing a 11 hour webm video(celluloid flatpak) i had downloaded off youtube,

the screen froze, I could still hear the video sound playing, but the system wasn’t responding to any keyboard presses(Wouldnt switch over to TTY2-4),

I had heard about REISUB and tried it, but it obviously didnt work, after about 2:30 mins the system unfroze and i was shuffled Across numerous TTY’s and the video closed as i had invoked CLTRL+Q

I am not here for a resolution to my problem The issue is reproducible by loading numerous instances of videos whose combined watch time Exceeds about 7-8 hours

I am more curious as to why SYSRQ is disabled and are there any consequences in enabling it(Security Wise)?

    I didn’t know that, It wasn’t working on Linux Mint the last time I checked, and i remember reading numerous articles about SYSRQ that mention that most distros ship with the feature disabled by default(Though not why they do that)
