Dear kind DragonflyBSD users,

I have managed to install DragonflyBSD 6.0.1 on an old machine with
integrated video on the motherboard.

The machine was running Dragonfly 5.2, but I wanted to upgrade it to
latest.  This has resulted in having no X.

the information from pciconf -lv

vgapci0 at pci0:1:5:0
vendor = 'Advanced Micro Devices, Inc.  [AMD/ATI]'
device = 'RS740 [Radeon 2100]'
class = display
subclass = VGA

The monitor am Acer Monitor which it is connected to supports 1600x900
output as follows:

Screen 0: minimum 320 x 200, current 1600 x 900, maximum 16384 x 16384
DisplayPort-0 disconnected primary (normal left inverted right x axis y axis)
HDMI-0 disconnected (normal left inverted right x axis y axis)
DVI-0 connected 1600x900+0+0 (normal left inverted right x axis y
axis) 443mm x 249mm

   1280x800      59.91
   1152x864      75.00
   1280x720      60.00
   1024x768      75.03    70.07    60.00
   832x624       74.55
   800x600       72.19    75.00    60.32    56.25
   640x480       75.00    72.81    66.67    59.94
   720x400       70.08

I have installed xfce and when I type startx I get a blank screen, and
pressing CTRL+ALT+BACKSPACE does nothing(maybe depracated),
I have to reset machine or turn off holding power button.  Any
suggestions as to how to get this working are appreciated.

Best Regards,
