Bug Description

Observations from using the Xubuntu bionic beta-1 (2018-03-06) installation image on a USB stick.

1) Sometimes during a boot from the USB stick, the video (Nvidea) is detected correctly and very quickly the expected first 2 screens appear (Language, Install/Try menu). While this happens and on into the installation or live session, performance is acceptable.

2) Sometimes during a boot from the USB stick, the video is not detected correctly and an alternate screen set is presented. While this happens and on into the installation or live session, performance is extremely slow.

Whether you get one or the other seems to be a matter of luck. Both cases are eventually reproducible.

Is this bug the result of trying to test suspend in a virtual machine?

This was a Live Session without VM.

The OEM screen report (#1754150) and this one are probably related.

Sometimes when I boot that machine with the installation USB stick, the video hardware is detected correctly and I see your mp4 sequence of screens.

Other times when I boot the same machine with the same installation USB stick, I see what I reported on #1754150.

I think that the slowness and the alternate screen sequence is related.

The attachment is what I see when video detection succeeds.

The attachment is the 1st screen when video detection fails.
