But now even the solution with tty provided there doesn’t work. I opened tty, logged in, then tried the command ‘sudo reboot’. This worked before, but not this time!!!
The problem started with the network manager or network adapter. One of them hangs my PC. There is looping animation on the control panel. It won’t connect to network, and also it won’t allow me to reboot from the panel (GDBus error:org.xfce.SessionManager.Error.Failed: Session manager must be in idle state when requesting shutdown)
I can’t open the normal terminal from anywhere, tried 3 different methods to open the normal terminal, nothing works. As was said, the trick with tty doesn’t work either.
When I click on the looping animation PC hangs for 10-15 minutes, then PC unfreezes and the animation begins again.
Is there any way to kill this process that causes the trouble?
I tried also the command Alt+SysRq+e, but couldn’t find SysRq key. The article said to try PrintScreen instead of SysRq, but this has zero effect. It doesn’t work.
I’m totally out of any ideas… Please, help!!!
Edit: I left PC hoping it will go to sleep, but it won’t. However, after around one hour it started to run some processes. It said something like “OOM killer enabled”. But this doesn’t lead to anything.
[user@user ~]$ sudo reboot
After this the cursor moves to the next line which is totally empty. Nothing happens at all, I have waited for an hour. There appeared 3 lines "audit: type=113… terminal=? res=success’ "
Is there any way to kill network manager? I think this will solve the problem.
