A couple of days ago I upgraded my 21.10 system to 22.04 and got this
"out of memory" issue (Dell XPS 15 9550 with 3840x2160 display).
The fix in comment #41 worked (changing the compression to 19), and the
sequence of commands in #44 helped. However, just noting that there are
several typos in
Joseph, out of interest, what model of XPS 13 do you have? I'm getting
new XPS 13 soon and wondering if it'll have the same issue (I guess it's
likely given the 4k screen).

Just a note: in attempting to fix this issue I borked my laptop - after
disabling UEFI boot and then re-enabling it in the BIOS settings, I
couldn't boot at all. So I reinstalled Ubuntu and then was getting the
following issue after doing system updates (but still on the 5.4
kernel):
Just noting that I had this same issue on my Dell XPS 9550 laptop, which
has a 3840x2160 display. The workaround of setting GFXMODE=800x600 in
the grub config worked for me too, thanks! And of course had the nice
side effect of actually making the grub menu readable. :-)

Charles, very interesting. Though I wonder if yours is a different
problem, partly because it's not in tty mode at all (for me it's in a
graphical mode, sometimes with the Dell logo up). I can't seem to switch
to tty2 using Alt-F2 or Ctrl-Alt-F2 -- what are the exact keys you're
using?

Good data point, thanks. It looks like there are some significant
differences between the 9550 and the 9560 that could explain that:
1) Next generation CPU: i7-6700HQ on the 9550 vs i7-7700HQ on the 9560
2) Intel HD graphics 530 on the 9550 vs 630 on the 9560
3) NVIDIA GTX 960M on the 9550 vs

Title:
Black screen on boot after 20.04 upgraded to kernel
The kernel it's trying to run (assuming it's the top one in the
"advanced options" boot list) is 5.8.0-36-generic.
I run apport-collect in case it helps -- boy, that's noisy in terms of
number of comments. :-)
