Portrait Display Drivers For X11?

helloRockview asks: "I have a MAG LT541C TFT, which I often use as a display for my Linux machines. Its best feature is that is has the ability to swivel into portrait mode, which works great when it's hooked up to a Windows box with 'Pivot' software installed. I'm wondering if there are any such utilities for X that will switch screen orientation from landscape to portrait on the fly." We did this question over a year ago and there didn't seem to be an answer, might there be one (or more) now?

    If I understand your question, switching between portrait and landscape mode should be easy.

    I would use XF86Config to define two resolutions: one for landscape, one for portrait. The dimensions you use should be porportionally opposite from each other

    Edit your /usr/X11R6/etc/keys.conf file to contain a line to define F12 to change the resolution. I'm not sure how you could go about this as I don't use X, but it should be easy.

    Alternatively, use Meta-Control-plus and Meta-Control-minus to change the resolution on the fly. In your XF86Config file, define only two resolutions, and M-C-+ or M-C-- will swap you between the two. Hope this helps.
