Good morning,

I’m a newcomer to Linux,

I installed OpenSuse 42.2 a few months ago and I’m happy with it.

The only new one that gets locked from time to time, that is, I can move the mouse, does not take any command, not even a keyboard.

Tried to do: Ctrl + Alt + Shift + Del but nothing.

I must brutally use the power off button.

Is there a file where errors or problems are logged?

It does not happen often, but I would like to solve it.

An early thank youhttp://www.suseitalia.org/sites/suse.ildn.net/files/selection_855_0.png

Never seen that or heard of any such thing.

  • Where did you get your openSUSE from?
  • What Desktop are you running?

In any case it might be possible to repair whatever is causing your problem by one of the following

  • Do a DVD repair. Use the regular DVD install disk.
    Follow that up with updating your system with the following command
zypper update
  • Do an online “upgrade” using your existing repositories.
    First, disable all your repos except for your OSS and OSS update repos
    Then, run the following
zypper dup

Then, re-enable the repos you disabled and then do an update

zypper update

Also, before your screen locker kicks in, for whatever Desktop you’re running you can go into the Desktop Preferences or configuration and either disable the screenlocker altogether or set the time of inactivity to something high.

I think I saw same screen one time but don’t remember about details. You can restore by another way: if you use BTRFS, you can try to use YaST’s snapper to rollback. It has a GUI even in console.
something about logs: https://www.linux.com/learn/sysadmin/viewing-linux-logs-command-line

Out of curiosity, do you have a large number of applications open?

I saw similar behaviour on my system after upgrading to 42.2, and found
that I had run out of process handles - 42.2 introduces a process limit
that wasn’t present in earlier releases (the reason it’s there makes
sense - to limit the ability of fork bombs to take the system down).

I ended up having to increase the number of limits for all users to work
around it - the limit was just too low for me.

What you can do to see if this is what’s causing your problem is to open
a terminal window and then just use the system as you normally would.

If the process limit becomes an issue, trying to do anything in that
window will result in a message saying ‘no processes remaining’ or
something to that effect.

It’s probably not that (since you say you can’t do anything - I could
switch windows), but worth checking out.

You can also, in that terminal window, try running ‘sudo tail -f /var/log/
messages’ and see if that tells you anything useful when the system has
locked up.

The issue has been posted by another user, should be resolved, I posted myself and no one who had the problem, then no longer answered if he solved or not thank everyone
;):wink:

I just wanted to add that I have seen that message. It occurs for me when the screen locker kicks in while doing an update (presumably including plasma files). It’s resolved by logging out and logging back in, but that is rather challenging when it is locked. Best solution is to not allow the screen locker to kick in while updating. :wink:
