The kernel and user space fixes addressed the same technical problem (failing to note that mode setting turned on the devices), but the symptoms that this caused were different; in kernel mode, the result would be that monitors would be left turned on when user space asked that they be turned off (and left pointing at random memory too, which was amusing). I think that the backlight issue was caused by the user-space bug though. -- keith.packard at intel.com -------------- next part -------------- A non-text attachment was scrubbed...
