GTK+ Forums

I've started running an xrandr 1.2 enabled X server, so that I could switch my laptop back and forth between the laptop LCD (LVDS) and a larger external monitor (VGA). Going from VGA->LVDS works fine, but in the other direction GTK+ apps segfault. For example, xterms work fine in either direction, but gnome-terminals segfaults going from LDVS to VGA. This is on Ubuntu Feisty.

I've done a backtrace on a simple GTK+ app and here is what I see

#0 init_xinerama_support (screen=<value optimized out>) at gdkscreen-x11.c:617

should gdk_x11_screen_size_changed be calling init_xinerama_support?

Are there known issues between rand1.2 and gtk/gdk?
