From: Paulo Zanoni <[email protected]> My laptop has two 1440x900 modes: one is the fixed_mode and the other has different timings. If I use xrandr to switch from the fixed mode to the "other" 1440x900 mode, xrandr will tell me the change was successful, but nothing was actually done: I'm still using the fixed_mode. This patch allows us to use other modes if hdisplay and vdisplay are the same.
