Hi,

xorg 7.3.2 and FreeBSD 7 Stable
Ive got the problem that I can't switch between resolutions with ctrl-alt + like you'd expect.

Thanks.



Ive got the following xorg.conf

Previously, you could only change the physical resolution of the monitor, but not the virtual resolution, giving you, for example, a 1024x768 physical resolution, but being able to pan around a 1280x1024 virtual resolution. With the inclusion of xrandr 1.2, you can change both the physical and virtual at the same time, but you can no longer change the physical without changing the virtual.

Really? How do you change the virtual screen size? I have set mine to 3360 x 1920 to cover all use cases I require. But most of the time 1440x900 would suffice.
 
As I said, you can't change the virtual resolution, at least not if your video card supports xrandr 1.2. The "Virtual" line in your xorg.conf now will reserve space/memory for dualhead setups, allowing you to add extra screen real estate without having to restart Xorg. And in really recent versions of most video card drivers, that is no longer usually necessary as the driver queries your monitors and Xorg does the calculations ahead of time.

Isn't that the opposite of what you just said? I cannot change my virtual, and I never was able to. But I always was able to change the physical resolution.

@francach
I think you can script something around xrandr -s and use the key binding feature of your window manager.

No, it is not the opposite.

Using xrandr, you can change your resolution, both the physical and virtual (assuming your video driver supports xrandr). However, your physical and virtual will *always* be the same now, so maybe it's best to just forget the concept of virtual resolution.
