** Patch added: "Felix Kuehling's xserver-xorg-backclear patch"
   http://launchpadlibrarian.net/45103003/xserver-xorg-backclear.patch

** Description changed:

  Binary package hint: fglrx
  
  [Environment]
  * You are using fglrx restricted driver from Ubuntu repository or download the linux driver from AMD ATI website (fglrx version <= 8.723.1-0ubuntu3).
  * If your ATI card is listed in the following pdf, then your desktop behaviours will most likely be affected the 'bugs' listed in [Symptoms] section.
-   https://a248.e.akamai.net/f/674/9206/0/www2.ati.com/drivers/linux/catalyst_102_linux.pdf
+   https://a248.e.akamai.net/f/674/9206/0/www2.ati.com/drivers/linux/catalyst_102_linux.pdf
  * GNOME and KDE SC 4.
  * Compositing desktop is enabled (Compiz and KWIN).
  
  [Symptoms]
  * Window Management: Unminimizing, Maximising, Full-Screening, Resizing windows and Switching windows (Alt+Tab) will noticably freeze the screen for about 1 second plus. Your mileage might vary.
  * Memory (RAM) Management: Secondary problem you might notice is memory leak and/or memory-clearing problem (http://www.phoronix.com/forums/showthread.php?t=21471).
  
  [Workarounds]
  * Window Management:
-  - Using PPA (Lucid Only) by Bryce Harrington (not up-to-date as of time of writing)
-    PPA address @ https://edge.launchpad.net/~bryceharrington/+archive/violet
-    In terminal, 'sudo add-apt-repository ppa:bryceharrington/violet' then install the update and reboot.
-  - Compile your own packages - when the ppa is not updated fast enough (or you are an update-freak like me)
-    + You need to tick 'Source Code' option in Synaptic Repositories or add relevant source code repo (deb-src) if you are using ppa:ubuntu-x-swat/x-updates.
-    + Building instruction:
- 	  sudo apt-get build-dep xorg-server
- 	  sudo apt-get install devscripts
- 	  apt-get source xorg-server
- 	  cd xorg-server-*
- 	  wget http://launchpadlibrarian.net/32728179/xserver-xorg-backclear.patch
- 	  patch -p1 < xserver-xorg-backclear.patch
- 	  dch -l -backclear-local 'Backclear Patch' #make package local to precede the unpatched version
- 	  debuild -us -uc
- 	  cd ..
- 	  dpkg --install xserver-xorg-core*.deb
- 	  dpkg --install xserver-common*.deb

  * Memory (RAM) Management:
-  - In terminal, run 'glxinfo' command or invoke 'glxgears' to release the 'uncleared' memory. You might need 'mesa-utils' package installed.
-  - Create a bash script to run at start up
-    #!/bin/sh
-    while [ 1 ]
-    do
-      glxinfo
-      sleep 60
-    done
