** Description changed: X is not correctly detecting my monitors' timings. Despite being a digital connection (with allegedly EDID), I have to force a modeline with xrandr. The graphical xrandr tools (arandr, or KDE's system- settings) do not work. I used to think this was solved with the binary drivers (first nvidia, then fglrx), but I now realise that a modeline can be generated with xrandr and they will work with the open-source driver. The 1600x1200 monitors are a pair of 20" 1600x1200 VideoSeven devices, purchased in 2006, with DVI and VGA inputs. I'm using both of the DVI inputs, (one of which via an HDMI/DVI adapter cable). They tend to be a bit fussy about being driven at the required 60Hz x 75 kHz, saying that the signal is out of range: they need 60x75, they are getting 60x75, but it's not good enough!). I attach xorg.log to this. Also, here is what I get when I run xrandr (to list modes), then when I run my xrandr.sh script , then xrandr again. The 60 Hz mode is now listed as "59.9". I'm filing this on xserver-xorg-core (2:1.15.1-0ubuntu8), though it might be a video-driver bug: xserver-xorg-video-radeon #Output of Xrandr. At this point, only the DisplayPort monitor works rightly.
