Thanks Ben, It took some time to actually test it properly but indeed the pixel-density (dpi) changes. Now I will delve through the manpages how to fix the dpi values in X (so that they always match my laptop's internal display).
BTW With a different (less capable) secondary monitor attached the problem did not occur. Apparently X is trying to be (too) clever with querying the monitor's capabilities. On 11/6/06, Ben Winslow <[EMAIL PROTECTED]> wrote:

My guess is that X is either configured with or detecting your display size, and assuming that the doubled resolution (e.g. 2048x768 instead of 1024x768) is being displayed on that same size instead of being spanned across two monitors. This would result in the display DPI being calculated incorrectly (e.g. 96x96dpi becoming 48x96dpi), which would cause any fonts renders that cared about DPI (FreeType does) to use the wrong size. The easiest way to test this would be to run the following command in single-head and dual-head mode, comparing the results: xdpyinfo | egrep '(dimensions|resolution):' Example output from my workstation: dimensions: 1456x1095 pixels (363x270 millimeters) resolution: 102x103 dots per inch You can override the display size in your xorg.conf by adding a 'DisplaySize <width-mm> <height-mm>' statement in the "Monitor" section. If the DPI calculation is wrong because the same size is being used for twice the resolution (as described above), you can hack around the problem by simply doubling the width (or height, if you have your screens laid out vertically.)
