Connecting an ASUS VW222S [1] over VGA a garbled screen is shown with vertical stripes in the top half.
This patch, which was merged in v3.6-rc4, makes the image on my ASUS VW222U ca. 1 inch too wide left/right and top/bottom. The effect is as if the image was zoomed (bigger, more pixely).
Reverting it fixes the problem.
I am sorry for the trouble caused by this. As a work around, you could also specify the QUIRKS on the Linux command line.
The Monitor is connected via VGA, but also has a DVI interface.
Maybe the quirk-apply criteria is too unspecific?
Hmm, I guess everything is identical but the DVI connector they added to the VW222U. Though I should have noticed the effect on the VW222S and did not. :(
Hm.. why should you have noticed the effect on the VW222S? Does it happen there too?
Could you please send the `edid-decode` output on your system and `/var/log/Xorg.0.log`.
I attached the xrandr --verbose output and the # get-edid | parse-edid output from http://www.polypux.org/projects/read-edid/ which I already had installed. Hope this works for you too.
Also I wonder how this quirk could create such a behavior.
Yes. I'm not shure how this could happen. It probably is either a bug somewhere, or it is the 'natural' effect of misconfiguring the vga pipeline. Maybe someone more knowledgeable than me could make a more educated guess about this.
