Description Aaron Plattner 2004-08-11 17:29:35 UTC

For rotation, randr needs to swap the screen's physical dimensions to avoid
changing the dpi.

Patch to set screen physical size

This patch stores the screen's original physical size in the randr screen
private, uses that to set the physical size in the modes reported by xrandr,
and then uses those sizes (appropriately rotated) to set the new size on randr
events.
