Computer/Display information TODO

[bp0]

The Computer/Display component of hardinfo is out of date.

Things to work on:

• Use xrandr for screen resolution information (Don't use GNOME stuff, would fix [from Ubuntu] hardinfo -r from comand line always shows displays in X as 0x0 pixels #200) [Done in GPU and Display Information #237]
• Bug Display includes the default screen number in the extension list #230 [Done in GPU and Display Information #237]
• Separate GPU info from X display info, and don't get device information from X. GPU information from X is wrong if using it over a network [Done in GPU and Display Information #237]
• Properly interpret core and compatibility profiles for OpenGL and OpenGL ES, and for each card, via glxinfo (doesn't properly identify opengl version #27, fix detection of OpenGL profiles and ARB_compatibility #170 was an attempt, but I don't think a correct one) (GPU and Display Information #237 lists them individually)
• Get Vulkan information vulkaninfo (fix Add Vulkan Information from vulkaninfo #171)
• Wayland info?
• Mir info?
• drm?
• display/monitors: monitors via X: xrandr --prop and parse-edid
• devices/monitors: Monitors on the local machine, like: cat /sys/devices/platform/soc/soc:gpu/drm/card0/card0-HDMI-A-1/edid | parse-edid)

Get vendor-specific information for each GPU:

• nvidia nvidia-settings -q all -t & /proc/driver/nvidia/gpus/
• vc4 vcgencmd ...
• nouveau?
• amdgpu?
• radeon?
• intel? intel-gpu-tools
• dmesg (not always available to non-root)
• glxinfo (only valid when local!)
• device tree (dt gpu: find gpu in the device tree #278, devicetree: get opp-v1/v2 freq range for gpu, if available [v2] #286, etc)
