Go to settings ->3D configuration -> projection -> projection type->. Cycle through the projection types. One of them causes something good enough to call a crash.
I don’t remember anymore if it was just a display driver crash or a kernel crash and I haven’t updated to a newer version (which might have fixed it).
It needs to startup and then go to that point (after you select the projection) to cause the crash.
It definitely caused something other than the application to get into an invalid state. Which is why I am apprehensive about trying it out again to answer your comment. Probably was the display driver, which is why it didn’t just turn off after that.
I’ve tested the command and it worked flawlessly in the terminal, but I have no idea what I’m doing, since I’m new to rust and never worked with this library
I’m guessing if input was “”, then it would sigkill all processes? Less confident, but some functions behave slightly differently in an interactive console vs a non interactive, maybe ps has a different format when used non interactively?
Aside, you want three backticks and a newline to get code formatting :)
I forgot to trimm the string, so it had a line break in it which lead to grep showing the processes from the term I put in + all processes that contain a space/linebreak and appearently all processes shown by ps aux contain some kind of space (makes sense, since there are spaces between the user, pid, etc) so yeah, I ended up trying to kill every process on the system, but it only killed the user processes, since I ran everything without sudo
Doesn’t explain OPs task management example. And won’t crash the kernel, just make things unresponsive
There’s this game “HyperRougue”. Run it on Arch.

Doesn’t even startup on my box, but doesn’t crash the kernel or system either, just regular application crash

it didn’t crash the kernel, it just killed every process that isn’t run by the root user, which kind of feels like a crash
Ah, that definitely would feel like a crash. Sent kill signal to cgroup accidentally? Or just iterate over all processes and signal them all?
probably the later, but idk how, all I did was insert a string in the following command like this:
``Command::new(“bash”)
.arg(“-c”) .arg(format!(“ps -aux | grep -i "}" }’ | xagrs kill -9”, input)
.output()
.expect(“error”);``

There are rust libraries to send signals, might be better to use those rather than calling bash. eg. https://docs.rs/nix/latest/nix/sys/signal/index.html

pshas a different format when used non interactively?thx, btw I figured it out:
