--- Comment #22 from Anton Gubarkov <anton.gubar...@gmail.com> --- (In reply to Aaron Lu from comment #19) > BTW, do you have Windows and does it have this problem? I do have windows on this machine. It does have problems with brightness, but they exhibit differently. I received a lot of updates for Lenovo power manager recently. It seems that Lenovo tries to address the firmware problem with OS/userland utilities. The brightness also drops when I plug/unplug AC, but only for a split second. After that it is restored to the previous value. I presume it's userland power manager who is watching over this. -- You are receiving this mail because: You are watching the assignee of the bug. ------------------------------------------------------------------------------ Learn Graph Databases - Download FREE O'Reilly Book "Graph Databases" is the definitive new guide to graph databases and their applications.
