-LyX has been tested with all Qt versions since Qt 4.2.2. For compilation
-you need to compile against at least Qt 4.2.2. The only special point to
-make is that you must ensure that both LyX and the Qt libraries are
-compiled with the same C++ compiler.
-
-Note that if Qt is using Xft2/fontconfig, you may need to install the
-latex-xft-fonts package (at ftp://ftp.lyx.org/pub/lyx/contrib/) to get
-maths symbols displayed properly. To find out, type:
-
- ldd `which lyx` | grep fontconfig
+For full LyX usability we suggest to use at least Qt 4.6 which has been
+widely tested. For compilation you need to compile against at least
+Qt 4.2.2. The only special point to make is that you must ensure that both
+LyX and the Qt libraries are compiled with the same C++ compiler.
