Bug Description
[Impact]
TTY switching is not possible on some workstations when iGPU is present and NVIDIA GFX is boot VGA. On that case, fbdev /dev/fb* is not created.
[Fix]
Find the correct boot VGA and remove overlapped aperture (BAR), so fbdev can be created properly.
[Test]
Once the fix gets applied, /dev/fb0 is present and TTY switching works.
[Where problems could occur]
The fix is a major overhaul over resource management on video apertures (BAR), so the boot VGA discovery might change and different aperture might be evicted.

This bug is awaiting verification that the linux/6.2.0-30.30 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification- needed- lunar-linux' to 'verification- done-lunar- linux'. If the problem still exists, change the tag 'verification- needed- lunar-linux' to 'verification- failed- lunar-linux' .
If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.
See https:/ /wiki.ubuntu. com/Testing/ EnableProposed for documentation how to enable and use -proposed. Thank you!
