Interestingly, after rebooting twice (and starting xfce4 as a first
desktop) X11 came up with a correct dpi value of 96x96, and everything
looked well again. So it's definitely a problem of the dpi settings.

Furthermore, I experienced similar problems with odd and asymetric dpi
values on my notebook with oneric too. So it's a general problem.


Since I was hunting another problem and sometimes booted both machines in the so called "recovery boot mode" without that initial splash screen,  I guess that this might be the problem: If the splash screen hasn't been run at boot time, ubuntu/lightdm/X11  seem to have problems with finding good dpi values (or maybe strictly calculates them from the physical screen size reported from the display, thus getting these odd values).

Title:
  X started by lightdm renders X11 screen ugly/unusable

Status in “lightdm” package in Ubuntu:
  New

Bug description:
  Hi,

  after upgrading my system to oneiric, the X11 desktop is ugly and
  almost unusable, because the fonts and characters are stretched
  horizontally and blurred.

  I guess that the reason is a wrong/odd dpi value, because xdpyinfo
  says

  screen #0:
    dimensions:    1600x1200 pixels (473x302 millimeters)
    resolution:    86x101 dots per inch

  
  I would prefer to simply give X a better dpi value as a command line argument, but as far as I can see that damned lightdm does not allow to configure any command line parameters for X (which I consider as broken design).

  Please tell me how oneiric is supposed to deal with that problem.
