Emacs does not work with new Dell Display

Emacs does not work with new Dell Display

[Johs]

I have just changed to a Dell 2007 WFP 20" widescreen display, but when I 
try to open emacs in Ubuntu it looks like this:

I have tried to remove my .emacs file but it does not help. Is emacs limited 
to work with certain displays?

That should work.  It looks like an X11 driver bug to me, or some
missing X11 fonts.

Do other Xt/Xaw programs work?  Try opening xman or xpdf.

If it's the font press shift+mouse1 over the frame and see if selecting
another works.

Your display is not to blame.  There is a bug in the Emacs21 package
in Debian and Ubuntu.  I don't know the exact solution to your problem
but it's in there:

http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=352811

Don't be fooled by the 'unreproducible' tag.  I've heard many people
have had that problem

F-D

If your running under X, I doubt it is a problem with emacs not being
able to display on a wide screen as I think from the emacs
perspective, it is unaware of that level of physical information (i.e.
this type of issue is handled by the X server). 

The square boxes are usually a sign emacs is having trouble finding
the right fonts. Try other fonts and see if you get a similar problem. 

FWIW I'm running a 24 inch Dell wide screen with absolutely no
problems with either emacs 21 or emacs 22. I'm running under Debian -
in fact, I have this configuration on two different systems (at home
and at work) with two different video cards (one intel, one ati) and
previously had it working with a gforce2. I've used various different
fonts - courier, lucidatypwriter, fixed etc. On one system, I'm
running a font server, but on the other I'm just running with a
fontpath in the xorg.conf file.

This problem is the interaction of Emacs and X.org config.  It can
affect Debian and Ubuntu.  See the Debian bug
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=352811 and the Ubuntu
bug https://launchpad.net/distros/ubuntu/+source/xorg/+bug/53038.
There has been quite a lot of discussion about where to best fix it.
See the threads for details.

It affects every part of X on the relevant distributions.  Type
"xfontsel" to see what I mean.
The problem is fonts used to be in /usr/share/X11/fonts/ now they are
in /usr/share/fonts/X11/, the config file xorg.conf was not updated to
reflect this change.
