System hangs

[Van_Vinkle]

Some weeks ago, I've bought a new desktop. It is an powerful enough one: AMD Ryzen 5 4500 6-Core with 16 GB RAM.

From the first day, and after the installation of Salix on it, it was very fast and worked well. But a problem arises: more often than desired it hangs and I can only do hard poweroff (Alt+PetSys+B).

I think that is an issue due to very fast processor. If I do double click on the mouse and I move it involuntarily a very small segment, the freeze occurs.

In my system there is, as usual, the Xkill tool. I think that if I could launch Xkill when the system is freezed, it was not necessary to cut off the power. But I ignore how to launch it with, for instance, Crtl+Esc+X.

Then my question: how can I configure the system for launching Xkill?

Thanks in advance.

If the system is actually freezing, then you won't be able to launch anything, including xkill.

BTW, I think you're looking for alt-f2, but again, if the system freezes, it won't work.

Is it the whole system that freezes, or only X? Try to open a virtual console with Ctrl-Alt-F2. Does that work?

And try to monitor the system temperatures, run sensors from the command line, or better use the xfce sensors plugin to continually monitor those.

Some keys run: for instance Crtl+PetSys+B cutting off the system and rebooting.
When the system will freeze again (today it has not done yet), I will try Crt+Alt+F2.
