Bug: Minimize Windows freeze Unity Desktop 15.04

Solution: If you use Tweaks to disable or hide the Desktop Icons which are displayed by Nautilus Filemanager Unity is often freezing on maximize or minimize the Windows of Apps like Firefox or Chromium-Browser. This is NO Compiz or Graphic Chip Driver Problem! Its seen on Intel HD, Radeon or Nvidia Graphic on „fresh“ Systems!

No Log Entry’s are made!! by the System, User must often hard reset the PC or restart Lightdm Login Manager on Console!!

Speed up Ubuntu Disable Window Animation Black Frames

Today i setup the Ubuntu on a AMD64 PC cause i want to
see the news that are arrived.

I always wait some month after the OS release appears!!

The new 9.10 Ubuntu should always be installed with new
clean install, cause there are too many changes behind the
desktop! It seems like a big change from XP to Windows 7!

To speed up the Desktop, i use a 7600GT Card, i disable all
Gimmicks at System-Settings->Window-Appearances and enable
Support for handicapted users (first box) and relogin!! to
get changes.

now to get more speed i run as user
go apps
go metacity
select „reduced-resources“

Voila…no animation,speed minimize and maximize..
