setting window geometry with xprop

jt1122 · 01-23-2024, 07:38 AM

I'm trying to set a window's geometry (position+dsize).
There's wmctrl & xdotool but their geometry isn't always accurate, so trying xprop.

Code:

xprop -name firefox

shows _NET_WM_USER_TIME_WINDOW 0x0480b6c8

Trying to set its geometry with

Code:

xprop -id 0x0480b6c8 -format _NET_WM_OPAQUE_REGION 16i -set _NET_WM_OPAQUE_REGION 100,100,500,500

but nothing happens.

any ideas?

Thanks

Applications built with the X Toolkit will accept a command line argument of the form -geometry WIDTHxHEIGHT+XOFF+YOFF (where WIDTH, HEIGHT, XOFF, and YOFF are numbers) for specifying a preferred size and location for this application's main window.

Firefox does not accept this command line argument. Having browsers open with a defined geometry is considered a privacy risk as it can be used for finger printing
