 part of the nvidia-kernel package at SlackBuilds.org.

+Since this nvidia-driver conflicts with some files of xorg, it's a bit
 complex to install/uninstall the driver.  However, installation of the
 nvidia-driver package itself backs up the conflicting files and puts the
 nvidia-specific files into place.
 
 Heinz Wiesinger, the author of the build script, has written a script called
 nvidia-switch, which can be used to switch between the stock xorg driver and
-the nvidia driver, but it will not edit xorg.conf for you; you have to do 
+the nvidia driver, but it will not edit xorg.conf for you; you have to do
 that manually.  The nvidia-switch script is installed to /usr/sbin.
 
 Usage of nvidia-switch:
   nvidia-switch --xorg	 <-->  switch to the stock xorg files
   nvidia-switch --nvidia  <--> switch to the proprietary nvidia files
+  nvidia-switch --cleanup <--> switch to the stock xorg file and remove all
+	symlinks created by nvidia-switch
 
-Before uninstalling this package, it is important that you execute 
-'nvidia-switch --xorg', which will switch back to the stock xorg files. 
-If you forget to do this, you'll have to do the switch manually, or xorg 
+No special steps are necessary when updating nvidia-driver from a previous
+package. If you update to a newer xorg, you do not have to reinstall
+nvidia-driver either. Just run "nvidia-switch --nvidia" in that case.
+
+Before uninstalling this package, it is important that you execute
+'nvidia-switch --cleanup', which will switch back to the stock xorg files
+and remove all links created by nvidia-switch before.
+If you forget to do this, you'll have to do the switch manually, or xorg
 won't work on next startup.  Here are the affected files:

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.  Line
+# up the first '|' above the ':' following the base package name, and the '|'
+# on the right side marks the last column you can put a character in.  You must
+# make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':'.
