Comment 10 for bug 2007001

Hi everyone,

I have built a test kernel based on the current 5.19.0-38-generic kernel for
both Kinetic and Jammy HWE. It has the below patch reverted:

commit 5e01376124309b4dbd30d413f43c0d9c2f60edea
Author: Thomas Zimmermann <email address hidden>
Date: Mon Jul 18 09:23:18 2022 +0200
Subject: video/aperture: Disable and unregister sysfb devices via aperture helpers
Link: https://github.com/torvalds/linux/commit/5e01376124309b4dbd30d413f43c0d9c2f60edea

The revert patch is below:

Could someone please test the test kernel to see if it fixes the problem on
their kinetic VM running on VMWare?

You may want to make the grub menu selectable first, in case the test kernel
does not work, so you can easily swap back to 5.19.0-29-generic which works.

Edit as root:
/etc/default/grub

Change GRUB_TIMEOUT_STYLE=hidden to GRUB_TIMEOUT_STYLE=menu and add a decent
timeout GRUB_TIMEOUT=30

Then update grub:

$ sudo update-grub

If you can test 5.19.0-38-generic from -updates first, and then test the test
kernel, it would be best to compare the two directly. Hopefully the test kernel
resolves the issue.

Please note this package is NOT SUPPORTED by Canonical, and is for TESTING
PURPOSES ONLY. ONLY Install in a dedicated test environment.

Instructions to install (on a Jammy or Kinetic system):
1) sudo add-apt-repository ppa:mruffell/lp2007001-test
2) sudo apt update
3) sudo apt install linux-image-unsigned-5.19.0-38-generic linux-modules-5.19.0-38-generic linux-modules-extra-5.19.0-38-generic linux-headers-5.19.0-38-generic
4) sudo reboot
5) uname -rv
5.19.0-38-generic #39+TEST2007001v20230418b1-Ubuntu SMP PREEMPT_DYNAMIC Tue Apr 18

Upon boot, you should be able to see the screen as normal on your VMWare VM.

Let me know if the test kernel works.

Thanks,
Matthew
