Setting drm_kms_helper.dp_aux_i2c_transfer_size to 1, 2 or 4 the dongle works, 8 doesn't work. Even with the default setting, I was able to: xrandr --addmode DP1 1920x1080 xrandr --output DP1 --mode 1920x1080 and have the dongle "work" - though xinerama was kind of messed up - applications didn't realize that there were two separate displays. I also have a DP to HDMI/DVI dongle that works fine with the default setting.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
