intel driver not setting DisplaySize correctly

[Jacobo Polavieja]

Hi all!

I'm having some issues with a external display over a laptop and it dpi
and DisplaySize.

Thouh I specify in xorg.conf that my external monitor has a DisplaySize
of 433x271 and I get full resolution, it somehow doesn't detect it so
well. The result is I have bigger fonts than I should have without
having changed any configuration. It happens on GTK2 apps as well as any
other app like urxvt.

xrandr output: You can see it doesn't detect TMDS-1 size

Tried to manually set the DPI but didn't worked (xorg.conf attached).

Any idea? Thanks!
