There’s an annoying bug that don’t permit to make a fresh install of gutsy on some machines without having really big fonts, that makes the system unusable. it seems that’s a bug in the dpi detection and there are a few ways to resolve this, for example copy your monitor characteristics from xorg.conf from feisty, and forcing dpi for the gdm, this might solve every problem.
but there’s a much simpler way to get it to work well at least on my intel gma…
first of all make a backup copy of your xorg.conf, this way you can get it back if something goes wrong
cp /etc/X11/xorg.conf /etc/X11/xorg.conf.bak
sudo gedit /etc/X11/xorg.conf
and find these lines:
Section “Device”
Identifier “Intel Corporation … Express Graphics Controller”
Driver “intel”
change the Driver “Intel” line to
Driver “i810″
save and reboot. if everything’s fine and i810 is the right driver for your intel gma, you should have a good resolution for your fonts.
