dual monitor setup with seperate resolutions

RikSolo · 2014-08-04 11:19:58

hey guys!
i currentley run thye latest version of archlinux with the cinnamon desktop environment and an nvidia geforce 7300SE graphics card.

im running a dual monitor setup with one 27" 1920x1080 monitor and one 27" 1024X768 monitor
because they have the same physical size they line up perfectley but because the resolution is different programs/mouse cursor movement doesnt, is there any way (without changing the resolutions) to compensate this effect so that in the eyes of linux/cinnamon the monitors line up so that for example dragging a window goes seamlessley between the 2 monitors.

i HAVE found out the panning option in the nvidia x server settings, but that really isnt what i am looking for...

A 27" running at 1024x768? That must be an older 720p TV/monitor.

yeah, ik its kinda weird, but its there... it is an older monitor indeed (about 1.5/2 years)

1080p is quite a difference compared to 720p. I would think the 1080p would almost be sufficient. The difference in resolution also causes a problem with the fact that you have to resize the window, not just clipping desktop. It might be better to have two separate X windows instead. Although, I'm not sure how to accomplish this or what purpose this would serve.

I highly doubt it. A window that is 384 pixels tall takes up half of your screen on the smaller monitor. When you move it to the larger one, you want it to still fill half and be 540 pixels tall? I don't know how this can work when you are in the process of dragging a window. Windows are supposed to be rectangles, not trapezoids.

A magnifier following the window down to the pixel, zooming to the exact size of 540 pixels the 384 pixels window could create an illusion of just that. It would be highly impractical however, not mention all the hacking time. Even if you would manage to get two screen with different sized icons, so that they match visually, the windows and fonts resizing on the fly, wmctrl might help with windows alone, no their themes (buttons, borders thickness etc.), you would still be left with a visually differently sized mouse cursor. Technically such a feat should be possible, but who is going to code it? Nvidia?

I think xrandr --scale ... will do what you want. I used to fake a 1920x1200 screen on a 1366x768 monitor - sounds kind of like what you want. You will need to run xrandr on each screen separately (you might not have to do the "normal" screen), each with it's own scale value. Anyway, check the scale and transform keywords in the xrandr man page.

Edit: not sure if nvidia-settings and xrandr will play well together, but it's worth a shot.
