Bug#1010357: extra info
No problem if I use: LIBGL_ALWAYS_SOFTWARE=1 MESA_DEBUG=1 gnome-control-center gnome-control-center also works if I use: MESA_GLES_VERSION_OVERRIDE=1.0 MESA_DEBUG=1 gnome-control-center (gnome-control-center:5552): GLib-WARNING **: 10:59:38.934: GError set over the top of a previous GError or uninitialized memory. This indicates a bug in someone's code. You must ensure an error is NULL before it's set. The overwriting error message was: Unable to create a GL context Gsk-Message: 10:59:38.934: Failed to realize renderer of type 'GskGLRenderer' for surface 'GdkWaylandToplevel': No EGL configuration available gnome-control-center works without error if I use: GSK_RENDERER=cairo MESA_DEBUG=1 gnome-control-center The program seems to work without problems, but I sometimes get errors: (gnome-control-center:6102): GLib-GObject-CRITICAL **: 11:43:46.650: g_object_unref: assertion 'G_IS_OBJECT (object)' failed (gnome-control-center:6102): GLib-GObject-CRITICAL **: 11:43:46.651: g_object_unref: assertion 'G_IS_OBJECT (object)' failed Maybe you could reproduce the problem at a more powerful graphics card by: MESA_GLES_VERSION_OVERRIDE=2.0 MESA_DEBUG=1 gnome-control-center

I am using a DELL Latitude D620 laptop with Core Duo inside. It only supports i386. lscpu Architecture: i686 CPU op-mode(s): 32-bit Address sizes: 32 bits physical, 32 bits virtual Byte Order: Little Endian CPU(s): 2 On-line CPU(s) list: 0,1 Vendor ID: GenuineIntel BIOS Vendor ID: Intel Model name: Genuine Intel(R) CPU T2400 @ 1.83GHz I am running Debian Testing for a long time without this problem. I have the impression somehow a switch is made to GTK-4.
