I´m new user in fedora 17 Security Lab, is excellent, but it is killing me, the bright desktop, in my laptop.
How can change?
and tested this tip:
start-up configuration 'GRUB2', and adding at the end of the line 'GRUB_CMDLINE_LINUX' and within their quoted, the following:
$ su -c 'nano /etc/default/grub'
GRUB_CMDLINE_LINUX="......... acpi_backlight=vendor acpi_osi=linux"
save the changes and reconfigure the boot loader again:
$ su -c 'grub2-mkconfig -o /boot/grub2/grub.cfg'
and nothing happened.
yum reinstall bash.
and again, nothing happened.
any help is valuable.
