By default, xrandr does not detect the correct resolution of the HP LP3065 monitor. I am using a regular version of Ubuntu Raring (3.8.0-19-generic x86_64). I receive 340 "[drm:intel_dp_i2c_aux_ch] *ERROR* too many retries, giving up" messages at startup (through dmesg). The following command: "sudo get-edid | parse-edid" detects the HP LP3065 monitor resolutions though. My workaround so far has been to run the following commands after booting the laptop: xrandr --newmode 2560x1600 268.00 2560 2608 2640 2720 1600 1603 1609 1646 -hsync +vsync xrandr --addmode DP1 2560x1600 xrandr --output LVDS1 --off --output DP1 --mode 2560x1600 Where the above parameters are specific to the parameters received from the "sudo get-edid | parse-edid" command. The same monitor plugged through DVI without the display port adapter worked just fine on a different Linux machine.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
