What I've seen is the same as described with the initial bug description: When monitor is connected via hdmi I get wrong colors. This appears during boot before the gui (x.org) gets started (frame buffer boot animation). Wrong colors (sort of violet instead of black) also appear on frame buffer text console and with x.org gui. This bug appears with "amdgpu.dc=1" kernel parameter. While running x.org I've turned the monitor off and on again. This gives correct colors but the screen resolution goes to 1024x768. So it's no work around. What I've seen is: The colors are correct if I run the monitor with a yuv color model instead of rgb. One thing seems to be better: Every boot manged to get to the graphical login. I've tried about 10 reboots.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
