--- Comment #22 from Timo Aaltonen <tjaalton at ubuntu.com> ---
the mesa part is now fixed, but the modesetting driver in xserver needs to be
fixed too:

hw/xfree86/drivers/modesetting/drmmode_display.c:    
xf86CrtcSetSizeRange(pScrn, 320, 200, mode_res->max_width,

vs. 
src/sna/sna_display.c:
xf86CrtcSetSizeRange(sna->scrn, 8, 8, INT16_MAX, INT16_MAX);


currently with xserver 1.19.3 it's not possible to configure 3x4k row of
monitors unless the -intel ddx is used.
