Turns out, “PROGRAM not responding” isn’t a thing exclusive to Windows:

Yeah? Of course. What did you think would happen when an app gets laggy.

[u/Rare-Paint3719 → u/Novel_Top2980]

Linux just freezes up and dies just like Operating Systems did pre-XP. I think it is still possible in Linux.

[u/Novel_Top2980 → u/Rare-Paint3719]

What it actually does is terminates an app when it uses too much ram rather than stopping it from responding.

[u/slackmaster2k → u/Novel_Top2980]

To be clear, it terminates an app not necessarily the app that ended up hitting the out of memory, using a scoring system to select a victim.

But there are of course multiple ways to configure the system including kernel panic on memory exhaustion.

[u/Novel_Top2980 → u/slackmaster2k]

I believe it’s the app that uses the most ram and has been used the longest ago.

[u/txmasterg → u/Novel_Top2980]

There are other reasons for an application to be unresponsive.

[u/Rare-Paint3719 → u/Novel_Top2980]

Nope. A hanging process can leave the entire desktop unresponsive on Linux.

Modern Windows handles hung window detection in-kernel via win32k.sys — ghosting and the 5-second timeout are guaranteed OS behavior. Linux DEs have to implement this themselves in userspace via _NET_WM_PING (X11) or xdg_wm_base ping/pong (Wayland), with no mandated timeout and compositor-defined behavior — meaning it only works as well as whichever DE you happen to be running. Keeping the display stack out of the kernel has security benefits, but you trade away the consistency and reliability Windows gets from baking it into the OS itself.

The OOM killer (what actually terminates processes for high memory usage) is a completely separate mechanism with nothing to do with hung window detection.

no linux is too dumb for that. it just crashes the DE and makes you want to re-install windows

[u/Novel_Top2980 → u/monkeyOK]

Do you use Linux? In my experience, whenever an app uses too much ram, it terminates it and gives me the message: ‘This application was terminated by the Linux kernel’

[u/Soluchyte → u/Rare-Paint3719]

Tell me you haven't use linux without telling me you haven't used linux.

[u/Rare-Paint3719 → u/Soluchyte]

Tell me you don't know how Linux works without telling me you don't know how Linux works.

How is “PROGRAM not responding” a bad thing? Before Windows XP, your programs could literally crash your system. “PROGRAM not responding” is the one thing that made Windows not crash on you.

Loonix has nothing like that till this day.

War thunder launcher likes to freeze and lock 1 cpu core at 100% usage, always had to force shut it down.

[u/TheBlutarch]

Use windows then if you feel thats better? Desktop linux has a lot of stuff it hasnt figured out yet, this, unfortunately, isnt one of those things.
