I miss a task manager-like shortcut to come out to the desktop and easily kill processes freezing the PC.
At least KDE has a shortcut in the Window Management settings that kills any window you want with a single click. You just press the key combination (Meta+Ctrl+Esc by default) and your cursor turns into a skull. Then just left click the frozen window and it closes instantly. Never had it fail, you can even kill your Desktop if you miss lol
FYI, on other DE's you can just bind
xkillto whatever shorcut you want. I tried it recently and it works just fine on Wayland.TIL Thanks!!!
You're welcome, it's a pretty handy feature.
Totally. I've keybound
xkillor similar to recreate that experience.Correct me if I am wrong, if I switch away from a fullscreen application, I won't have it available to be terminated using xkill, right?
In that case you would switch back.... my thought is to add xkill or similar to a keybinding so it can be called without switching away from the thing.
And knowing what's actually eating cpu cycles. Sometimes 4 threads are at 25% but usage should be like 4-5% per thread.
Ctrl+alt+t -> xkill -> click window you want to terminate
But yes I agree that seeing a better GUI of open programs and attached processes would be good to have.
I'm sorry what? Ctrl+Alt+t is bound to opening a terminal emulator (whichever I fancy ATM) on any system I use. I know it's a Ubuntu binding but I got so used to it if I'm ever on a system that doesn't have it I just hammer it 15 times till I gather that it's not set up there so this would never work for me 😅
Yeah, i just mean open terminal then type xkill and click. I thought ctrl+alt+t was the default in ubuntu/mint
I had a problem with Unity games on Steam freezing the PC due to fractional scaling. In that case not even the terminal would show up. Also, if I switch away from a fullscreen application, I won't have it available to be terminated using xkill, right?
In case you haven't tried it, you can run Steam games in native Wayland mode, and get a more stable experience. Especially with fractional scaling. There are two steps:
env DISPLAY="" PROTON_ENABLE_WAYLAND=1 %command%I am on Mint. For now. Anyway I am quiet quitting Steam for GOG and Heroic had no problem running Unity games with fractional scaling.
If you can't see the terminal, then that's pretty bad so idk -> if everything goes unresponsive I just slap my monitor in impotent fury and reboot
If you can see the terminal but not the window, idk if xkill would work. Then you'd need to find the process id and kill it with pkill.
Like say you're playing age of empires 2: pgrep aoe (should return all running processes called aoe with their pids > process: aoe2 pid: 69420 ...or something like that) then: pkill 69420 > ded

Yeaaa..nope.
We definitely need a better UI with highest prio for this.
A few select games, Notably Watch Dogs 2 and Fallout: New Vegas, probably because of Proton bugs, occasionally freeze my (Debian+i3wm) desktop. My computer is not frozen, but my desktop session is. I can take my smartphone and SSH into my desktop to kill the game's process (or Steam, which will take the game with it when it dies).
I've come to enjoy this process because I feel like some kinda movie hacker.
How much ram you hauling? I've had similar issues when voices of the void sprung a memory leak in an earlier build, completely froze my KDE until I nuked it.
48G but that's not. I have plenty left over whenever it happens, and running out of memory has never frozen my desktop.
Shit that's crazy. I guess the syslog might help but I know it won't give you wine/proton logs, and I've not worked out how to get at those myself yet.
You should be able to switch tty to access the system directly from the pc. If you're unaware... ctrl alt f3 will switch to another terminal where you can login and access things. Generally your default sessions is in f2 (ymmv) so ctrl alt f2 should return you to your desktop where you left off once you nuke the offending pid.
Yes, I am aware, but my keyboard can't do that shortcut
PSA Don't buy a 60% keyboard for use with Linux...
You can always come out of everything to a separate terminal, not sure how many users actually know that.
It's not always helpful or even very friendly, but it can save butts.
Ctrl + Alt + F1 or ...F6, sometimes even up to F8. Usually desktop is at F2. Sometimes it's not. But you can check them any time.
There was one time years ago I was working on some unholy mess of mods for Transport Fever and the game kept crashing and bringing the whole X session down with it, and instead of just rebooting like a sane person I instead started a new X session on a new terminal session. I think I got up to 4 or 5 dead x sessions before I finally finished sorting out my mods and rebooted to clean it all up
I use Mission Center because I'm someone who prefers a GUI. Maybe that will help some here. :)
IDK what desktop environment you're using... or your specific scenario... but most DE should have something like that. KDE and Gnome have a version of "system monitor" which will work very much like task manager on windows.
https://apps.kde.org/plasma-systemmonitor/
https://apps.gnome.org/SystemMonitor/
Generally there are preinstalled and already assigned a hotkey.
Cinnamon
I believe cinnamon uses gnome system monitor by default so there should be a way to set a custom hotkey for it in settings.
