           Summary: Exceeding render target size in xorg.conf breaks
                    everything
           Product: xorg
           Version: unspecified
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/nouveau
        AssignedTo: nouveau at lists.freedesktop.org
        ReportedBy: tomi.pievilainen+freedesktop at iki.fi
         QAContact: xorg-team at lists.x.org


If settings in xorg.conf exceed the maximum render target size (4096x4096
here), the system ends up in a state where X can only be activated again after
a reboot. Would be better to notice this and just bailout with an error
message.

When trying to exceed the size with xrandr (for example when rotating a
monitor), another monitor is disabled. Rotating back won't re-enable the blank
monitor, but rebooting X will help.
