I no longer see the problem on Ubuntu 13.10. Both monitors show as DVI connected and both work fine.

After 11.10 install completed, the right-hand 23" monitor remains blank and in power save, although when I open System Settings / Displays, both monitors appear there with the initial display configuration showing as mirrored displays at 1152x864 resolution. Un-mirroring the displays and setting each display to its native resolution and orientation still has the LH monitor blank. I think the problem is that the 23" monitor is being incorrectly detected as being connected via HDMI, as when I run xrandr in a terminal it shows =================================================== nick@ubuntu1110:~$ xrandr Screen 0: minimum 320 x 200, current 3640 x 1920, maximum 8192 x 8192 DVI-I-1 connected 2560x1600+0+0 (normal left inverted right x axis y axis) 641mm x 401mm 2560x1600 60.0*+ 1920x1440 60.0 1920x1200 59.9 1600x1200 60.0 1280x1024 75.0 60.0 1280x800 59.8 1152x864 75.0 1024x768 75.1 60.0 800x600 75.0 60.3 640x480 75.0 60.0 720x400 70.1 HDMI-1 connected 1080x1920+2560+0 right (normal left inverted right x axis y axis) 509mm x 286mm 1920x1080 60.0*+ 1280x1024 75.0 60.0 1152x864 75.0 1024x768 75.1 60.0 800x600 75.0 60.3 640x480 75.0 60.0 720x400 70.1 =================================================== The video card does not have any HDMI output at all, just the two DVI outputs.
