Resolution higher than 1024×768 for Acer x233h external monitor is not available

[Stéphane Guillou]

I use Ubuntu 13.10 64bits on my Asus F201E, and when I plug in my Acer x233h via VGA as an external monitor, the maximal resolution available in "System settings > Screen Display" is 1024×768 (as well as 800×600), but the maximal resolution of the screen is supposed to be 1920×1080.

I have no proprietary drivers available in "System Setting > Software & Updates > Additional drivers", and I installed the latest version of the Intel Linux Graphics Drivers from https://01.org/linuxgraphics/downloads, thinking it would help (version 1.0.3), to no avail.

This seems it should not be the default behaviour.
Any help would be greatly appreciated, as this external monitor ends up having a maximal resolution that is inferior to my tiny laptop... :)

No EDID is found for your monitor (and the hardware doesn't report any errors when trying to retrieve it). So you have to add the modes manually (xorg.conf or with xrandr, or maybe there is a gui option by now?) or pass a fake EDID to use.
