Comment 20 for bug 954352

Enabling the wayland and x11 backends of gtk+ simultaneously appears to be unusable: https://bugzilla.gnome.org/show_bug.cgi?id=672361

Related to the cairo-gl vs. Nvidia proprietary problem:
A) Get cairo-gl to only load libGL when an application requests it: https://bugs.freedesktop.org/show_bug.cgi?id=47480
B) Get the Nvidia proprietary driver to reduce memory consumption. I haven't touched this one. All I have found is linux-bugs at nvidia.com mentioned on http://www.nvidia.com/object/linux_display_ia32_169.09.html
C) Remove the cairo-gl dependency from the wayland backend of GTK+: https://bugs.freedesktop.org/show_bug.cgi?id=47480
D) Add support for versioned provides to the Debian packaging system: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=7330
   This bug is 15 years old.
