So the different behaviour occurs based on whether I start X before or after plugging in the DVI-D DL dongle. If I plug it in before starting X, it does not correctly detect the higher resolutions, and I am unable to force it to do so by adding the modeline via xrandr. If I plug it in after starting X, it works as expected. I have attached four files: xrandr and dmesg outputs from both cases. I just realised that I had drm.debug=0xe, not drm.debug=6. If this is a problem, let me know and I'll reboot to try again.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
