[SOLVED] gnome-screenshot never quits and it messes up Xorg!

[DaveJones]

Hi all,
I recently had an issue where Cinnamon's nemo wouldn't launch any new processes. When I tried double-clicking on some file, nothing would come up. Cinnamon also couldn't start anything.So i tried running things from the command line and noticed this error:

Code: Select all

Maximum number of clients reached

It turns out that X11 ran out of resources. After looking at all the processes, I noticed a huge number of gnome-screenshot processes. So after I invoke a s screenshot tool with a keyboard shortcut, it never quits after finishing. And every time I run it, a new process is started.

If I run the ps and grep gnome-screenshot, this is what I see right now:

Code: Select all

if you don't reboot often and if you use gnome-screenshot few times a day, these instances accumulate and make Xorg not start new processes.
Is there a fix for this? Not sure where to report this issue.
I'm running the latest Cinnamon 4.6.7, nemo 4.6.5, and gnome-screenshot 3.38.0.

Thanks!

Hi Dave.
Put "gnome-screenshot Maximum number of clients reached" into duck-duck-go and you'll find this is a long-standing problem for some configurations. Some say to start X with the following command to fix the issue:

Code: Select all

nohup /usr/bin/X11/X -ac -noreset &

Let us know if you find a fix.

You can also use Shutter instead of gnome-screenshot if you want to.

You could replace it with mate-screenshot - I think their functionalities are nearly the same.

Edit: mate-screenshot --help shows exactly the same options as gnome-screenshot: https://linux.die.net/man/1/gnome-screenshot

Thank you so much! After doing more searching, one of the temporary fixes that people do is to raise the number of Xorg's maxclients to a higher number. I'll set mine to 512 but this won't really resolve the issue...

Thank yo so much! I've just installed mate-screenshot but I am unsure how to tell Cinnamon to use it over the gnome-screenshot. I combed through System Settings and have looked at Keyboard section and I can only change keyboard shortcuts for screenshotting but not the program itself. Any idea how to switch?
Thanks again!

It's strange that you can't change it! I don't use Cin, so maybe start a new thread to fix that.

Yep, I'd like to bind it to PrtScreen like gnome-screenshot is currently bound to it. I don't see a way to do it however.

Here is a wild guess.
Menu - type Keyboard - select Keyboard.
Click on "Shortcuts" at the top.
Select "System" - "Screenshots and Recording" on the left.
Click on "Take a screenshot of an area" at the top.
Click on "Shift+Print" on the bottom.
Click on "Add custom shortcut" button on bottom.
Across from Command: enter "mate-screenshot -a" or some other command.
Give it a name.
see what happens when you hit "Shift + Print"

Hi, this doesn't work the way you described it. You simply cannot modify the built-in Screenshot commands. What actually happens is that Cinnamon creates a Custom Shortcut. You might as well go directly to Custom section and create a new shortcut there. You have to manually override all of the the built-in ones from "Screenshots and Recording" section.
Thank you!

Thanks! This works the same way... it overrides the built-in shortcuts. Cinnamon seems to be hard-wired to use gnome-screenshot, however.
Anyway, I've removed gnome-screenshot from my computer so there's no way that Cinnamon will ever use it and cause this issue again.
