** Description changed: Binary package hint: xorg Dual screen configuration was working fine with 9.10 with extended desktop. I use 2x19" monitors both set to 1600x1200. The screen seems to have been correctly drawn (3200x1200) in the desktop chooser applet. See picture attached to better understand. The windows can be placed outside the right limit of the screen. But in both the monitors is drawn the same screen, like it was a mirrored setup. The monitor preferences window identifies each screen with a coloured rectangle on the upper left corner: it reports the same monitor, the VGA0, no matter what I do. Nor " xrandr --output VGA-0 --left-of DVI-0 " neither the various visual tools seem to help Under suggestion of one user ofubuntu forums http://ubuntuforums.org/showthread.php?t=1468857 I did the following: Turn on the computer with the secondary monitor (for me the one attached to the dvi connector) unplugged. Login and THEN plug in the DVI connector. xrandr --output VGA-0 --left-of DVI-0 This actually works, but has to be repeated each time I turn on the computer, and isn't really practical. It does not work if I boot with the monitors connected and unplug before login. I'm available for whichever test you suggest. [edit] - I noticed a general degradation of the quality, it seems scattering and treribly slow with few apps open, expecially when using the extended desktop. + I noticed, when the secondary screen is enabled with the above trick: + a general degradation of the speed, it seems scattering and terribly slow with few apps open, expecially when using the extended desktop. + Videos in streaming (I tried with vlc) on the secondary screen hang and a fixed image is shown, while moving the window on the primary screen the video is correctly shown. Whenever I drag the video window on the secondary screen, it hangs, until I drag it back to the primary. Audio isn't affected. Is there a way to downgrade to a previous video driver or similar option?
