Hi,

I've seen a few people have UHD monitors working with their raspberry
pi3's.  I'm confused by a constraint that appears to be an X
constraint, and that's the size of the desktop.

Has anyone gotten this to work successfully using an openSUSE build?

This works:
#cvt -r 3840 2160 60
#xrandr --newmode "3840x2160" 533.00 3840 3888 3920 4000 2160 2163
2168 2222 +hsync -vsync
#xrandr --addmode HDMI-1 3840x2160

This doesn't:
#xrandr --output HDMI-1 --mode "3840x2160" --rate 60 --fb 4096x4096 --
panning 4096x4096

error is:
xrandr: screen cannot be larger than 2048x2048 (desired size
4096x4096)

How do I change the default to something larger than 2048x2048
(desired is 4096x4096)?

Is there a way to change it dynamically, or do I need to do some work
with xorg.conf files?
