Hi folks,
I'm having an issue where GTK-based apps spawn a context menu on the left-most screen, above where the screen actually exists. Everything worked fine on a previous install, but I attempted to switch to nouveau and ended up doing a clean install because I don't use a lot of system packages (thinking I had just effed something up in X).
I've seen this behavior in various programs - but am not sure to the extent of what is affected.
Known issues: nm-applet, virt-manager, nvidia-settings, gnome-screenshot
Qt-based stuff seems to work, so it seems to be purely a GTK issue versus system-wide. Windows spawn correctly, just not menus or windows triggered by buttons (eg gnome-screenshot's "help" button).
At first I thought it had something to do with my Xorg config, but I'm not sure anymore. In brief, my configuration:
- awesomewm
- two NVIDIA cards (970, 610) using xinerama. 970 is the main GPU and hooked up to the monitor physically on the right, 610 is hooked up to a monitor on the left.
- using nvidia driver (stable)
- two differently-sized monitors (1680x1050, 1920x1080)
- stock GTK theme, nothing custom installed whatsoever.
I know that everything works correctly with a single monitor. After moving my nvidia-settings generated configuration and restarting X, context menus correctly appear on-screen rather than a sliver at the top left.
My extra X config (/etc/X11/xorg.conf.d/nvidia.conf):

I've tried a few different configurations now to no avail, i.e.:
- Setting both screens to absolute positioning in my xorg.conf (Absolute 0 0 for the left, 610-connected and Absolute 1680 0 for the right).
- Using a different wm (bspwm, i3).
Using a simple xorg.conf, generated by nvidia-xconfig, does not exhibit this behavior. However, it is a single screen rather than utilizing both of the cards in the system.

EndSectionAt this point, I'm fairly certain the issue has something to do with NVIDIA/Xinerama - I'm not familiar enough with it to qualify that, though. I dropped a single "Screen" from the original "ServerLayout" (as posted in my original post, not this follow-up), and even then the context menus and various windows are started "off screen" or too high on the active monitor to be reachable.
I will continue to experiment and see if I can figure this out, but any help is appreciated.

Hello @ayylmao,
It seems to me that I'm facing a similar issue: https://bbs.archlinux.org/viewtopic.php?id=219633.
Have you found any solution yet?
