I am also hit by this bug on a HP Compaq nx7400 with Intel 945GM. Following https://wiki.ubuntu.com/X/Troubleshooting/HugeFonts it seems to be related to bad monitors. Since the several posts and bugs about the issue, I am writing as reference the following workarounds:
1) For the giant fonts making the KDE session unusable, here it is how I solved the issue: - after booting, ctrl-alt-F6 to go to a terminal session; - login with username and password; - type sudo nano .kde/share/config/kcmfonts - set DPI to 96 by editing the relevant line into: forceFontDPI=96 - save following on screen instructions - restart the session or reboot I adapted a suggestion made in this thread http://kubuntuforums.net/forums/index.php?topic=3107128.0 since the xterm trick did not work for me. 2) For KDM, similarly to the GDM case, one has to add "-dpi 96" to the line "ServerCmd=/usr/bin/X" in "/etc/kde4/kdm/kdmrc" (all without brackets obviously, I have just put them to distinguish relevant instructions from normal text). This solve the giant fonts issue in the login screen. I have adapted an old discussion from http://kubuntuforums.net/forums/index.php?topic=3087975.0 Hope it helps. -- [i945GM] Huge font size in KDE and GDM.
