Salix Forums

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.

Tested: When freezed Ctrl+Alt+F2 does nothing

Yes, that means that the entire system freezes. Did you check what kind of temperatures you had at the time it froze?

Also, run a memory test with memtest.

As far as I can see there is not a temperature issue:

Code: Select all

k10temp-pci-00c3
Adapter: PCI adapter
Tctl:         +38.9°C

The measurement was made a few minutes after the crash.

A few minutes is enough time for the system to cool down. Add a temperature monitor in your taskbar, so you know exactly the temperature when it hangs.

The system crashed again, and now I could take a picture (this one)

Temperature monitor says at this moment:
Temp1 49º C
Composite 42º C
Sensor2 46º C
Temp1 17º C
Temp2 17º C
Tctl 47º C

I don't know exactly what every abbreviation means, but apparently there is not any temperature out of order.

No, it isn't the temperatures. But do check your RAM with memtest. Freezes like these most of the times are hardware issues, unfortunately.

You could also try a newer kernel. You could try the kernel packages from slint: http://slackware.uk/slint/x86_64/slint-15.0/slint/

Memtest has been running for more than nine hours and no error vas found. Because I needed the machine I aborted memtest.

Then, I must have a new kernel. But in my system there are four kernel packages: k-firmware, k-headers, k-huge and k-modules. In the Slint repositories I cannot find k-huge and k-modules.

Any idea?
