From 51a51899d0e7eab93468f51296c196b2f3978332 Mon Sep 17 00:00:00 2001 From: Michel Dänzer Date: Fri, 12 Mar 2010 18:24:34 +0100 Subject: st/dri: Always try to set up R5G6B5 configs. Allows compiz to work in depth 16. The DRI2 getBuffersWithFormat hook is only required for 16/32 bit depth buffers, for colour buffers the only requirement is that the format matches the drawable depth, which we can't check here.
