[Bug 376722] Re: [i945] i945 don't recognize 1440x900 on external monitor in jaunty

 

*** This bug is a duplicate of bug 288807 ***

I'm sorry for the long time for previous message.

The laptop model is Sony vgn-sz1m, now about 3 years old.

To attempt a work-around I added explicitly the modeline for 1440x900,
using those parameters:

Modeline "1440x900" 103.97  1440 1496 1624 1856   900  900  902  933

the results is not very good: the desktop seems to be few percents wider
than the panel.

The randr --verbos output now appears as follow:
