Is there a way to blacklist an individual application from using overlay-scrollbars?

In their frantic quest for pixel real estate, Unity designers have set their greedy eyes on scrollbars and replaced the 30 years old standard vertical scrollbar with an evanescent slider (see for instance how Nautilus is behaving now !!!).

In addition, Steve Northover and the Standard Widget Toolkit folks where probably cooking there own scrollbar version on top of the GTK ones.

The end result of all this is that since my upgrading to 11.04, although I immediately switched back to 'Ubuntu Classic', my eclipse IDE becomes virtually useless as scrolling through large files becomes a lengthy mouse-wheel Odyssey.

Did anybody notice ?

Is there a known fix to this situation ?

yes, there is. Create file /etc/X11/Xsession.d/80overlayscrollbars and paste there this line export LIBOVERLAY_SCROLLBAR=0

oneliner could be

sudo su -c 'echo export LIBOVERLAY_SCROLLBAR=0 > etc/X11/Xsession.d/80overlayscrollbars'

is there a post recapitulating this kind of settings. A question (CW or not) such as "How to customize Unity if you don't run it on a tablet or a smartphone" ? – Alain Pannetier May 3 '11 at 18:29

I prefer turning getting rid of the overlays altogether, since they're a problem for more than just one application. dpkg --list |grep "overlay" | cut -d " " -f 3 | xargs sudo dpkg --purge – rbellamy Aug 25 '11 at 14:45

OK - found it. In addition to the fix mentioned by Denwerko, I discovered I was using

export GDK_NATIVE_WINDOWS=true

in my startup (to work around legacy GTK bugs).

Removing this environment variable make the overlay scrollbar usable again, albeit hard to catch.

I like this one - removal of a patch for a bugfix ages ago sounds better than adding more patches as above. – Danny Staple Oct 19 '11 at 13:42
