[Libdlo] module loads and unloads

RANAD is also a built-in extension.  Does displaylink support XRANDR ?
Anyone knows?

Try the following patch not to enable XRANDR:

+++ displaylink.c    2009-06-25 12:25:18.633459826 -0600

     xf86DPMSInit(pScreen, fbdevHWDPMSSetWeak(), 0);

-    xf86CrtcScreenInit (pScreen);
+    /* Don't enable XRANDR1.2 */
+    //xf86CrtcScreenInit (pScreen);

     pScreen->SaveScreen = fbdevHWSaveScreenWeak();
