Both Xorg with xf86-video-dummy-0.4.0 and Xvfb report physical size 0mmx0mm

Hi. Weird thing. Both Xvfb and Xorg with xf86-video-dummy-0.4.0 report 0mmx0mm even after explicit setting those values to some positive numbers with xcb_randr_set_screen_size_checked, xcb_randr_set_screen_size_checked_reply did not report any error. I simply can not make it work as expected.

What steps will reproduce the bug?

~ $ Xvfb :1 -noreset &
~ $ xrandr
Screen 0: minimum 1 x 1, current 1280 x 1024, maximum 1280 x 1024
screen connected 1280x1024+0+0 0mm x 0mm
   1280x1024      0.00* 
~ $ xrandr --output screen --fbmm 100x100
~ $ xrandr
Screen 0: minimum 1 x 1, current 1280 x 1024, maximum 1280 x 1024
screen connected 1280x1024+0+0 0mm x 0mm
   1280x1024      0.00*

Thank you very much for help.
