xorg server log
i have 3 display setup (dvi, dp, hdmi), displays on dp and hdmi are 10bit
displays, if i turn on deepcolor option on amdgpu driver, hdmi display got
wrong refresh rate (looks too low), display supported 1920x1200@60 mode, in
xorg.log we can see what it detected properly, but instead of this display got
like 40hz, and turn black with out of range error, i have played a bit with
modes, and found what mode "xrandr --newmode "1920x1200_73.48" 240.00 1920
2064 2264 2608 1200 1203 1209 1254 -hsync +vsync" works, display also warns
about out of range mode (58.7hz), but actually works, NOTE: this all happens
only if deepcolor driver option is turned on.
