Re: [Bug 1520355] Re: Kernel/Debugging/Backlight/Ubuntu Gnome 15.10

 

InUbuntu14.04with kernel3.16the issue issolved so: 
http://compizomania.blogspot.de/2014/06/ubuntu-1404linux-mint-17.htmlTo 
upgrade the kernelhas not yet happened, asthere was little timeand 
knowledge.Whenwill updatebe sure to writeyou. InDebianJessiehas decided 
as follows:addedin/etc/defaults/grubinthe 
variablevalueGRUB_CMDLINE_LINUX_DEFAULT="acpi_backlight=vendor"
