Bug Description
Binary package hint: xserver-
[Paul: This size 289x21 millimiters is reported by about 6 persons on Intel chipset, I have i945 but
mine is fine]
[Paul: other values seen: 40x30, 10x10 ATI radeon)]
Lure on the kubuntu-devel irc has given me a list of things to report. This report is to fix the following.

The screen res taken from xdpyinfo is
1280x800 pixels (289x21 millimeters)
The dpi taken from xdpyinfo is
112x968 dpi
I will add the log files shortly.
[Update]
This problem is caused by buggy monitors that emit incorrect EDID from their firmware. Fortunately, X.org has a mechanism for working around these bugs, but they're implemented specific to the particular model # of the monitor. So if you find yourself experiencing this problem, please file a NEW bug (don't reopen this one) against xorg-server titled "<monitor-name> produces bad EDID causing large font sizes; needs quirk", and attach the following information:
* /var/log/Xorg.0.log
* output from `sudo ddcprobe`
* output from `sudo get-edid | parse-edid` (you'll need to install the read-edid package)
