Freezes

[lanig]

Hi all,

Since a few days, I have been experiencing "soft" freezes with my system : suddenly  cursor becomes very slow, GUI doesn't respond aymore, CTRL-F-AL-Fn has no effect. Need to hard reboot.

It happenned even when Firefox was not  in the foreground. Where and how can I find clues to solve this problem ?

Thanks in advance.

Is this happening under X11 or Wayland? 

Anything in ~/.xsession-errors.old?

I've also had this behavior a few times.
I'm not sure, but it always seems to occur when a drive is mounted via NFS.

I am under X.
I got this in my ~/.xsession-errors.old

Look at /var/log/syslog and /var/log/messages for any error messages around the time of the freeze.

I have also been getting freezes, always linked to mouse click. I am using fully updated KDE with Wayland.

using an intel system?

No,  AMD

I think the culprit could be PDF4Teachers, a java app.

Ugh Java apps can really bring a system to its knees

In case it could be useful to others, finally the culprite seems to be my ssd drive.
