From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Why is SYSRQ Disabled on most consumer distributions? (lemmy.ml)

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)?

No, MKV files have weird artifact issues for me so I use MPV(Celluloid) which mostly just works

Never had any problems, not even on Android and 4k video. I did turned on full hardware acceleration though

my hardware struggles a lot and i find other odd quirks with VLC, I usually don't face such problems on MPV
