[nouveau] ubuntu desktop install & background is changing on selecting options(drop-downs) in ubiquity

[Chris Guiver]

QA-test of Ubuntu hirsute (desktop) RC on
- hp dc7700 (c2d-e6320, 5gb, nvidia quadro nvs 290)

** My error

I intended to hit "Install" and not "Try" but the desktop started in live mode, so I assume that was my error in selection... Because I was in 'try' mode I adjusted the display setup so it matched my setup. That was only change made, before clicking on "Install" icon on desktop & returning to the intended QA-test install.

** Expected result

As I progress thru dialogs in my Manual Partitioning install of Ubuntu Desktop, I don't expect the desktop wallpaper to change at all.

** Actual Result

The background wallpaper starting top left corner of my "upper" display started switching from normal background & going bright-blue. The area of blue kept growing on each dialog press in ubiquity until both displays were all blue.

I continued with the ubiquity dialogs (just clicked INSTALL NOW) but a number of clicks back all background wallpaper was gone, and I've two black monitors (no wallpaper is shown).

If I right-click background & look at "Change Wallpaper" it shows my current still as the default.

I can change it to some others.. but selecting the default hippo wallpaper or some? images and this firefox window now appears enlarged as my background..

Install (ubiquity) window appears perfectly normal (install is now copying files)

This issue is cosmetic only.

This bug is missing log files that will aid in diagnosing the problem. While running an Ubuntu kernel (not a mainline or third-party kernel) please enter the following command in a terminal window:

apport-collect 1925279

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

[Chris Guiver (guiverc)]

I'll change this to confirmed; the box is used for QA-test installs and any install on it is lucky to survive 2 days before it's gone.

I can run apport-collect on it but hirsute installs are now impish so it'll report differently.
