           Summary: X crash at start when virtual size exceeds the VRAM
                    capacity
           Product: xorg
           Version: git
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/nouveau

X crash at start when virtual size exceeds the VRAM capacity

Quoting marcheu who sort it out:

<marcheu> (EE) EXA(0): ExaDriverRec::offScreenBase must be
<ExaDriverRec::memorySize
<marcheu> bad bad bad bad
<marcheu> (--) NOUVEAU(0): VideoRAM: 16384 kBytes 
<marcheu> 2624*1200*4=12MB
<marcheu> we only use half of VRAM for 2D, and 16/2MB < 12MB
<marcheu> so you don't have the room to create that
buffer<marcheu> in fact, X
should refuse to start if the thing was any sane

I had:

        SubSection "Display"
                Modes           "1024x768"
                Virtual 2624 1200
        EndSubSection

My intention was to combine with a 1600x1200 LCD panel.

Attaching the Xorg.0.log with a backtrace at the end, and the xorg.conf...
