OK. I've now found out this topic is a hornets nest - anyone who is interested should take a look at http://bugs.freedesktop.org/show_bug.cgi?id=23705
I can't override the DPI in xorg.conf because it is ignored. I tried xrandr --dpi, but it didn't make any difference on the VGA system when I switched between 96 and 100, so the black left margin is still there. Not surprisingly, changing dpi with xranr on the DVI interface made no difference either. ** Bug watch added: freedesktop.org Bugzilla #23705 http://bugs.freedesktop.org/show_bug.cgi?id=23705 -- Invalid EDID for Dell SP2309W in VGA mode https://bugs.launchpad.net/bugs/563774 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-nouveau in ubuntu. _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : [email protected] Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
