Metamodes not restored

[Michael]

Hi,

I've noticed that when I use disper to change displays it deletes all of the metamodes not relevant for that display. This means that when I change back to that display, the metamodes are no longer available.

So for example, for my primary display I have some lower resolution metamodes in my xorg.conf for playing games full screen. I've written a shell script to toggle though the displays using disper: extended -> secondary (laptop screen) -> primary (lcd monitor). By default I have the display extended. So if I want to enable just the LCD monitor, I first toggle to the laptop screen, at which point all of the metamodes are deleted for the monitor, then I toggle to the monitor and the metamodes from my xorg.conf are no longer available.

Would it be possible for disper to read the xorg.conf and put back any metamodes it might have deleted?

I'm using disper version 0.2.3

Here's the output from disper when switching to the secondary display:

Thanks for your bug report. Disper indeed throws away all metamodes that don't fit the new setup. Is anyone using the existance of different metamodes? Please post here if you do so.
