Review request for Solid, Àlex Fiestas and Dan Vrátil.


Changes
-------

Adding bug entries that this patch fixes.


Description
-------

The change in XRandROutput::edid() allows us to use "if (edid->isValid())" instead of "if (edid && edid->isValid())". I think the former is cleaner.

The change in XRandROutput::updateModes() selects the first preferred mode found instead of the last one. At least in my notebook the first preferred mode has higher resolution, probably that is also valid for all modes returned by XRandR API.


This addresses bugs 312236 and 312951.

Testing
-------

Tested in my notebook. The change in XRandROutput::edid() is part of a crash fix for kscreen. The change in XRandROutput::updateModes() fixes a problem in my notebook's lcd, which includes several preferred modes and the last mode is the one with lower resolution.


Thanks,
