Nvidia Twinview loads classic Ubuntu top panel

[James Pursey]

Binary package hint: unity

Hi

After launching the Twinview function to enable multiple screens, the top panel from Ubuntu classic, ie Applications, Places, System + the Firefox launcher and any other launchers the user has put in the Ubuntu Classic top panel are loaded into Unity. They are, however, totally unusable - nothing happens when you press them. These buttons totally obscure any buttons needed to operate any applications you may be using, making them inoperable. Disabling Twinview does not make the Ubuntu Classic top bar disappear - it is necessary to log out and log back in to get the Unity panel to function properly again.

After the recent upgrades, the behaviour of applying Twinview has changed. The Classic Gnome menu no longer appears, but funny things do still happen. I've had the Ubuntu icon in the top left corner disappearing, the applets in the top panel blanked out and the Kde top panel replacing the Gnome one.

Hi, thanks for reporting this issue

can you make sure that gnome-panel and the kde panel are not loading in your session? and that you are logged into the Ubuntu Desktop session, not the classic desktop, it sounds like you are loading the gnome panel/kde panel underneath unity, they would normally be hidden until something shakes things up like changing twinview

Hi

I have since re-installed 10.10 (as my wife got cross with me over using a buggy distro!) but I hadn't ever logged into the classic desktop while using Natty. I'd be more than happy to re-install 11.04 if you wish me to provide any more information.

James, Now Ubuntu-11.04 beta-2 is out, you could either try that or wait for the final to release on 28th April and let us know if the issue is still there.

Hi Omer,

I've just tried again and I can report that everything seems to work normally now. I can't confirm for certain yet because I haven't used it for a long period of time - but it's looking good.
