Created attachment 21308 [details] Zip contains xorg.conf, Xorg.0.log and gdb_session.txt files. When xinerama is enabled on triple head setup, server works until client uses visual. When plain Xorg is run, everything seems working, X cursor moves across all 3 monitors. When I run xeyes, it works, however when I run xterm/urxvt (or most probably any other window using visuals), crash occurs. I've attached my conf, log and simple gdb session in a zip file.
Please do not attach zip files. Attach each file separately and mark the zip file as obsolete.

the root visual is NULL, sounds more like a server bug. although meh, nvidia.
Changed synopsis since the gdb session shows it's urxvt, not the Xorg server. (Which makes more sense, since the Xorg server doesn't link with libX11, so can't really crash there.)
root_visual = 0x0 in: (gdb) p dpy->screens[0] $3 = {ext_data = 0x0, display = 0x868a248, root = 982, width = 3960, height = 1050, mwidth = 1181, mheight = 309, ndepths = 7, depths = 0x8690bd0, root_depth = 24, root_visual = 0x0, default_gc = 0x8690c28, cmap = 32, white_pixel = 16777215, black_pixel = 0, max_maps = 1, min_maps = 1, backing_store = 0, save_unders = 0, root_input_mask = 0} I'd expect to see more reports about this if it were still an issue. Do you still have this problem with recent bits? If so, please try with nouveau rather than nvidia to eliminate a driver issue and reopen.
