xrandr: reflect option for rear projection

cnsodom · 06-22-09, 04:10 PM

Hi

I am working with a small projector that doesn't seem to have an option to invert or reflect the x axis. The project set-up demands rear projection.

I am able to rotate the display with xrandr, but there doesn't seem to be support for the --reflect option. The graphics card in this box is a GeForce 8800 GTX and we are using the 180.51-1... version of the driver.

Any help would be greatly appreciated.

We have no current plans to support this feature, but knowing how many people would like it will help us prioritize it against other work.

Thank you for your response. I have to say it makes me sad. I guess mirrors will do the trick.

Thanks again

Possibly you need to dig more in the projector. Seems inconceivable it would not do that. Might be something like a jumper somewhere, but more likely hidden in an installation menu or suchlike.
