Fonts, anti-aliasing and TFTs

Fri Jun 27 19:54:54 BST 2003

Thanks for the reply.

Yes I have tried with no sub-pixelling, and the problem is still there.
And I agree that it is very odd. I did a screen cap of a konsole window
and zoomed in with an editor, and sure enough, the lines are 1 pixel
wide and multi-coloured (this is with sub-pixelling off). With no
anti-aliasing they are solid black.

I'll send anyone who wants it a copy. In the meantime, I'm going to try
changing video drivers and then I'll try Mandrake. I have no reason for
thinking these will help, but it's something to pass the time until I
get a better idea.

Have you tried NO sub-pixel hinting (uncheck the box in Control Center
and 
restart KDE and X)?

This is very odd.  A pixel on a digital display consists of one Red one 
Green and one Blue element (a set of three) so if it is actually one
pixel 
wide, then it (if driven with a digital connection) should turn all
three 
colors off and be black.  Only when using the sub-pixel hinting on small

fonts should this happen.
