[Lazarus] Problems with Lazarus on Ubuntu 11.10

[Håkan Elmqvist]

I just installed Lazarus 0.9.30 on Ubuntu 11.10 and have run into all
sorts of problems.
Examples are:
Sometimes I can't switch between the source editor windows (a restart
helps), instead when I click on an editor-tab a breakpoint close to the
mouse cursor gets set.
I can't change editor font size
Alt-tab doesn't work as expected.
The Unity launcher gets unaccessible.
And more and more...

Is this an Ubuntu problem or a Lazarus problem? Is there any way to fix it?
What is the best Linux to run Lazarus on?
I have previously used Lazarus on Suse without any problems. I have tried
Mike MacDonagh's tips at
http://mikemacd.wordpress.com/2011/10/31/install-single-window-lazarus-0-9-30-in-ubuntu-11-10-step-by-step/
but it doesn't really help.
Any advice is appreciated.
