<pre>Yes. I can get the native resolution (4096x2160) to work in X. For a long
time, I've used the following mode line:
xrandr --newmode "4096x2160_60" 556.730 4096 4104 4136 4176 2160 2208 2216
2222 +hsync +vsync
But I noticed in the DRI source code that a DMT mode for 4096x2160@60hz exists,
so I tried that too, and it also works fine:
xrandr --newmode "4096x2160_60" 556.744 4096 4104 4136 4176 2160 2208 2216
2222 +hsync +vsync
I'm currently using a Dell XPS 15 9560, with a base station attached using a
thunderbolt port. The monitor is connected to the base station with a full
sized display port cable.
I've compiled drm-tip and included the kernel parameters you wanted. I waited
a while before logging in and capturing this dmesg I'm attaching.</pre>
