@ccheney
Regardless if my crashes are gone, my experience is that having a swap file in
recent Linux is deadly. If Linux starts swapping only a little then it's hardly
usable any more. I believe this is because of the algorithm that decides which
pages to remove from memory.
Your observation w
Probably fucked up installation was the cause of this. sorry for
bothering.
I recently reinstalled Kubuntu because I was frustrated with the stability of
my system. It still hadn't really improved since switch to kernel 5.4
And, magically, all the crashes are gone. So, no idea why but something i

kernel 5.3.0-29-generic still affected.
whenever swap is enabled, the system is almost unusable when cache grows
too large with time. as already told, this is by far worse than the
infamous linux swap trashing.
while this can be worked around easily, I am sti
Haven't had a problem for over a week now with kernel 5.4.1-050401-generic.
Strange, as a comment above says it happened with this kernel as well.
So it probably was fixed by the Firefox update?
updates since Dec 8th contain:
- Firefox from 69.0.3 to 71.0
- Thunderbird
- samba, git, wine, ssh,
There is for sure a bug.
As I said, I know how a system behaves that is suffering from too much swapping.
My case is far worse.
and still, about once a day the GUI is completely locked. this cannot be
explained from swapping and cannot be solved by disabling swap.
I think the only kernel yet th

I restarted GUI using /etc/init.d/sddm restart
right now only the KDE taskbar and menu are locked, Alt-Tab and programs still
work. (this is a rather new phenomena)

I am not sure if there are two different problems:
- the lagginess (repeated freezing for let's say some 100ms) when increasing
cache/buf makes the kernel swap too much (which is clearly different from a
system that suffers from heavy swapping, far worse)
- the complete and final freeze of the G
Which gui? well: KDE, Xorg, Intel driver, sddm. What exactly are you
asking for?
