Need monitor quirk to fix wrong DPI for Toshiba Satellite A110-160

[Santiago Urueña]

(See bug #120619: [Gutsy] invalid resolution detected resulting in BIG fonts on i915)

I downloaded today a daily Kubuntu build (karmic-desktop-amd64.iso 15-Aug-2009 05:46 652M), but the desktop was totally unusable due to the huge fonts problem. From the terminal, "DISPLAY=":0.0" xdpyinfo" reports the following DPI:

...
screen #0:
  dimensions: 1280x800 pixels (289x21 millimeters)
  resolution: 112x968 dots per inch
...

After killing the X session from the terminal, and launching it again with "startx -- -dpi 96", the problem totally disappeared! (in fact, I'm writing this bug report from the live CD :-)

Now, the xdpyinfo shows the following DPI:

...
screen #0:
  dimensions: 1280x800 pixels (338x211 millimeters)
  resolution: 96x96 dots per inch
...

I attach the Xorg logs of the problematic settings. This is the EDID info:

Hi, I just downloaded a kubuntu 10.04.1 (desktop) live CD, and this problem with the fonts is not happening again. The resolution is now detected OK, both the i386 and AMD64 versions.

I think this can now be closed, thanks!
