** Description changed: - As the summary states: there is no backlight on my Asus X52Je notebook - after boot - it works fine at the grub stage and splash sreen but - afterwards it just goes black (though you can barely see something - - that's why i could turn on the monitor clone option and use a secondary - display). Function keys work and there is an entrance in - /sys/class/backlight/ - it just doesn't do anything. - - I've had this problem since 12.04 - i think it started after one of the - software updates. It did work for quite some time before. I tried - upgrading Ubuntu in hope that that would fix it, but to no avail - I'm - now at 14.04 and all the versions up to this point had the same problem - (12.10, 13.04, 13.10). I also tried latest mainline kernel but that - didn't help. + There is no backlight on my Asus X52Je notebook after boot.
