Toshiba Satellite A665 backlight no workee with kernel update
Updated the kernel and now the backlight can not be adjusted up or down even though the GUI with the bars pops up and the bars darken and lighten with "fn-F6" and "fn-F7" keys. (Thats the function key along with the F6 and F7 keys.) The brightness just stays the same. Modified /boot/grub2/grub.cfg with "grub2-mkconfig -o /boot/grub2/grub.cfg" after modifying /etc/default/grub appropriately to boot the old kernel and the backlight is adjustable again. I did a search on this forum and nothing pertinent came up. Google was no help either. :*( So after doing what I thought was a good thing (which was no small matter with dial up internet connection) I'm back on the old kernel. Any thoughts on this would be appreciated.
