            Bug ID: 87061
           Summary: 1600x1200 resolution breaks at startup, but works
                    later with xrandr
           Product: xorg
           Version: unspecified
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/openchrome
          Assignee: openchrome-devel at lists.freedesktop.org
          Reporter: daniel at gnoutcheff.name

I have a large CRT monitor with a maximum resolution (as claimed by EDID) of
1600x1200.  If I try to start X with an xorg.conf that requests 1600x1200 as
the initial resolution (or if I start it without an xorg.conf), then the server
crashes with

> (II) CHROME(0): Required bandwidth is not available. (576000000 > 553000000)
> (II) CHROME(0): ViaDisplayDisableCRT
> (EE) 
> Fatal server error:
> (EE) AddScreen/ScreenInit failed for driver 0

However, if I start X with an xorg.conf that requests a lower resolution (e.g.
1280x1024), and if I later request 1600x1200 with

> $ xrandr --output VGA-1 --mode "1600x1200"

then the server accepts and switches to the higher resolution without
complaint.

Openchrome 0.3.3 (as packaged in Debian testing)
Xorg server 1.16.2 RC 1 (also from Debian)
