Hi, referring to the recent exchange here: http://www.spinics.net/lists/intel-gfx/msg91010.html the response only mentions correct gamma ramp support, but it looks to me as if there is much more missing than in existence when it comes to 30-bit color depth support in Linux using Intel Graphics. I, too, started with Ubuntu 15.10, on a Xeon E3-1275v5 connected via DP to a Samsung U28D590 30-bit capable monitor, installed the latest Intel Graphics drivers for Linux using Installer 1.4.0, and edited a copy of /etc/X11/xorg.conf.failsafe to add a "DefaultDepth 30" line. The result is an empty Ubuntu desktop. Further investigation showed that it is no longer possible to activate the OpenGL plugin in compiz, without which the Unity desktop cannot work. Checking the OpenGL support with "glxinfo" only shows a single visual, which is not 30-bit: 1 GLX Visuals visual x bf lv rg d st colorbuffer sr ax dp st accumbuffer ms cav id dep cl sp sz l ci b ro r g b a F gb bf th cl r g b a ns b eat ---------------------------------------------------------------------------- 0x055 32 tc 0 32 0 r y . 8 8 8 8 . . 0 24 8 0 0 0 0 0 0 None So it looks like there is missing OpenGL 30-bit color depth support as well. In fact, it seems the 30-bit color depth "support" for Intel Graphics on Linux right now is no more than UNACCELERATED framebuffer support. Is that it, or did I miss a step to enable 30-bit color depth support fully? If not, is there a roadmap by which Intel (or other project owners?) intend to deliver full support for 30-bit color depth? Daniel mentioned "4.7" for the gama ramp fix, is that Linux kernel 4.7? What about OpenGL support, would that need an update by Intel, MESA, or both?
