Backlight has been fairly solid for some years now. 1) Please paste the sysfs attributes *before* display gets disabled. 2) Is the behaviour reproducible if you don't go to minimum before disabling display? I.e. stay at the next higher level. Or, use # echo 1 > /sys/class/backlight/intel_backlight/brightness to stay above 0. We do have a check in place to crank the brightness to max if it's at the minimum upon encoder enable. However, that bit policy has been in place for ages.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are on the CC list for the bug.</li> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
