DisplaySize removed from xorg 7.2?

Just upgraded eveything, including xorg-server-1.2.0-3.
After the upgrade the DPI was forced to 94x95 by X and it just ignored the 'DisplaySize'-entry in xorg.conf.

Anyone know if they renamed or removed that command? Can't upgrade when it's impossible to get correct DPI.

Re: DisplaySize removed from xorg 7.2?

That is the exact issue I am having.. I posted a bug report on it. Maintainer is looking into it although i hadn't narrowed it down to the DisplaySize command. That makes perfect sense since my screen size got all screwy..

Re: DisplaySize removed from xorg 7.2?

It's probably a bug in xorg.
See https://bugs.freedesktop.org/show_bug.cgi?id=9758

Feel free to correct my English

Re: DisplaySize removed from xorg 7.2?

I forwarded that info to the bug report I had posted so the maintainer can look into it. Thanks for the info Prim I am sure it will help.

Re: DisplaySize removed from xorg 7.2?

Same effect here. But adding Option "NoDDC" to the Device section for the video card in xorg.conf seems to fix it.

The NoDCC-option did not work for me, unfortunately.
Let's hope they'll fix it for the next update.

Re: DisplaySize removed from xorg 7.2?

It's weird. It seems to work for me. Without it I have 98x96 dpi. With NoDDC option I have 98x98 but something is still wrong - different logs show different display sizes in mm. For example xorg log says 

(**) I810(0): Display dimensions: (331, 207) mm
(**) I810(0): DPI set to (98, 98)

which is exactly the size from DisplaySize. But xdpyinfo says 

  dimensions:    1280x800 pixels (332x207 millimeters)
  resolution:    98x98 dots per inch

I have no idea where this data come from :-)

Maybe it's just "luck" that NoDDC forced correct display size. I'm also pretty sure that xorg log should say something about using size from DisplaySize but it doesn't. Well, something is still broken...

EDIT: but if you are using different video card than mine and non open source drivers you should try other options like edid options for nvidia (NoDDC doesn't work anymore for this driver).

Re: DisplaySize removed from xorg 7.2?

I also had the same problem with 'DisplaySize' being ignored after an update. I use a nvidia card and it's drivers, so the advice to use edid options that lanrat gave really helped. I added Option "UseEDID" "FALSE" and Option "UseEdidFreqs" "FALSE" and got back to my resolution and refresh rate. I don't know, maybe only using the first option would be enough too. Anyways, somebody might find this feedback useful wink

Re: DisplaySize removed from xorg 7.2?

Nvidia binary users could just add

    Option "DPI" "100 x 100"

to their video-device section

Stand back, intruder, or i'll blast you out of space! I am Klixon and I don't want any dealings with you human lifeforms. I'm a cyborg!
