xorg.conf
Yes, xdpyinfo will lie. It has to. That DPI number is sent once at X client connection time and there's no way to refresh it if the monitor configuration changes. It's also _one_ number, which means it can't help but be a lie if you have multiple displays connected. The DPI values in xrandr are computed from the EDID of the attached display device, which means they can be (and apparently are) correct per-output. DisplaySize being ignored is probably a bug though. Could you please confirm if the DisplaySize is really being ignored (so a bug) or if it is just my xorg.conf that is not properly written? I am trying without sucess to make nvidia-settings recognize the correct display size and maybe I should just quit if it is really a bug.

Adam could you please reply Daniels question and probably close this issue? Thanks Tom In RANDR 1.2 the Monitor keyword in the Screen section doesn't really mean anything anymore. You need to associate Monitors with specific outputs in the Device section: Section "Device" Identifier "Device0" Driver "nouveau" Option "Monitor-LVDS-1" "Monitor0" EndSection Please reopen if that doesn't fix this for you. |
