I am using Ubuntu 12.04.4 uname -r 3.11.0-15-generic tested with Ubuntu 13.04 and 13.10 same problem There is no trace of error in dmesg, xorg.log For xrandr the display appear to be working. This is not a backlight error as the backlight is not handle by the motherboard. I should add that the eDP is converted to LVDS. intel_reg_dumper is not working for some reason "Couldn't map MMIO region: Resource temporarily unavailable" and can not manage to compile it due to depandancy error. However I can attached some log file is desired and/or test with a more recent Ubuntu version where intel_reg_dumper is working</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> </ul> </body> </html>
