Not sure if it's the same issue, but a fresh load of the preinstalled
Jammy image on Raspberry Pi 4 goes through most of initial setup, but
then goes to a blank screen. Subsequent reboots and restarts of gdm3
lead to a console screen with a blinking cursor instead of the login
screen. Manually
My assessment of the reason appears to be wrong, USB storage at boot
time isn't working for me under 5.13, but the modules seem like they're
present.

I think this is affecting the latest 5.13 kernels, the usb-storage
modules appear to be missing, and USB storage isn't working, I get the
device detected when I plug it in, but modules to use it are missing
since the 5.13 update.

I can confirm that this goes away under 20.04 with the HWE stack (kernel
5.8+)

Title:
Dell Vostro 5391 trackpad loses functionality after sleep
I don't have the links to document it right now, but it looks like the
'raspi' kernels forked from generic arm64 ones while there was a bug
involving Transparent Huge Pages that warranted turning them off. That
bug is long-fixed in arm64, but the raspi kernels appear to be keeping
it as a
I believe 'transparent hugepages' are still disabled in the latest
kernel configs, creating a significant barrier to THP usage (having to
build a custom kernel).
Would it be possible to change the configuration of the arm64/raspi2
kernels so apps that request huge pages can get them? The
OK. I'm running Ubuntu under Wayland now, and after the laptop wakes up,
the mouse cursor tracks -really- quickly on the trackpad and I lose
multitouch and right-click. I can still mouse-around and click, but no
more context menus or two-finger scrolling. A restart fixes it. I guess
it runs deeper
Public bug reported:
On 18.04 and 19.10, the Dell Vostro 5391 would lose the trackpad cursor
control completely, manifesting as a frozen cursor. On 20.04, it comes
back from sleep as a regular mouse, but tracks motion differently and
doesn't recognize any normal gestures or the right-click.
Public bug reported:
It appears that large page support and transparent hugepages are
disabled in config on the Raspberry Pi. It would be nice if they were
enabled in the kernel configuration, even if they are disabled by
default. Then they could be set in user-editable config via the
Public bug reported:
Bionic uses GNUTLS 3.5, and many programs embed its functionality (like
Samba). The OpenSSL library in Bionic was backported to support TLSv1.3,
but many packages using GNUTLS 3.5 are using an older branch (the stable
branch of GNUTLS is now 3.6).
