Use of external monitor fails in various ways. Only success is with 800x600 resolution, mirrored displays

[Christopher Barrington-Leigh]

On an Asus EeePC under 13.10, the regression beginning in 13.04 remains.

The externa monitor and its resolution options seem to be recognized, but actually choosing a configuration with extended desktop gives screen corruption, or other problems.

The mirrored display seems to work but only offers 800x600 resolution!

probably hitting a hw texture limit, though the mirror mode should be able to run better

[Chris Wilson (ickle)]

That is a PVR Atom, i.e. using an unsupported graphics chip as opposed to Intel's Gen graphics.

[Timo Aaltonen (tjaalton)]

good point..
