 .B Dualhead Note: 
-Changing modes on crtc2 in dualhead mode causes problems in
-some configurations.  The workaround is to switch the mode, change to another
-VT, then change back.
+The video BIOS on some laptops interacts strangely with dualhead.  This can result
+in flickering and problems changing modes on crtc2.  If you experience these problems
+try toggling your laptop's video output switch (e.g., fn-f7, etc.) prior to starting X
+or switch to another VT and back.
