For those still having this problem, please file a NEW BUG against xorg-
server on it. Include both your /var/log/Xorg.0.log, and the output of
`sudo get-edid | parse-edid` (you'll need to install the read-edid
package for this).
The problem here is that there is a _hardware_ bug in the monitor - it
lies about its capabilities. So each case has to be handled on a case-
by-case basis by 'quirking' the xserver to enable the appropriate
workaround for that specific piece of hardware.
Since we have to handle each individual problem on a case-by-case basis,
it is much easier to do this with separate bug reports, rather than this
big one (which is getting hard to follow and keep track of who all is
still having problems, and no doubt spamming people for whom the problem
is long since solved. *grin*)
@Samuel, I was able to get the necessary info to compose a quirk from
your Xorg.0.log, so no need for you to file a new bug.
@puccha, unfortunately your Xorg.0.log did not have detailed EDID info
listed so I don't know which quirk to use for you. Please file a NEW
bug and attach the info I mentioned above.

[Paul: This size 289x21 millimiters is reported by about 6 persons on Intel
chipset, I have i945 but
mine is fine]

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)
