Hi, Thank you all for the informative replies. After a day of testing and googling, I have finally found the cause of this problem and the solution. The problem is actually quite deep: It is not in LyX, it is not in Qt4, it is because I used a VNC session to use LyX 1.5 and my VNC server (RealVNC) doesn't support the X RENDER extension, which Qt4 uses to display anti-aliased fonts. (Instead, Qt3 doesn't use RENDER for the fonts so Lyx 1.4 displays ok.)
Instead of waiting for the next version of RealVNC, I switched to xf4vnc and this problem is solved. The speed now is a little slower, though. best, Sam On 2/28/07, Helge Hafting <[EMAIL PROTECTED]> wrote:

My lyx 1.5 beta (on debian) does antialiasing. Did you try something simple like tools->preferences->screen fonts? Make sure lyx-1.5 uses exactly the same fonts as lyx-1.4.3 do. Perhaps your xserver isn't capable of antialiasing all fonts, and lyx-1.5 might install itself with bad defaults. Do you have any other qt4 apps - do they get antialiased fonts? Lyx 1.4.3 uses qt3, any qt3 setup you may have done will have to be re-done for qt4 as well. Helge Hafting
