They now have to ask every user that reports an issue with the backlight to try setting that option on the command line. While I appreciate the setting breaks things for some people, doesn't the Win8 issue impact far more people? Shouldn't it be defaulted to true? If nothing else, can you add a config option for the default so distros can use that to decide which way to default it and then work on fixing the remaining users that have troubles? josh _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/intel-gfx
