Hi philipballew-

I'm surprised that you're having this trouble with my PPA on your Studio
1558, since that is the exact machine that I use to test the PPA and I
don't experience it. I have a few questions:

Are you using the default Gnome desktop or KDE (or something else?)

When it starts "all the way down", is is completely black or just very
dim?

Does the graphical login screen appear with darkened brightness, or does
the problem only occur when you log in?

Do the brightness control hotkeys work normally after that, or not?

Finally, please send me the output from running these commands in a
terminal window:

$ uname -a

$ ls /sys/class/backlight

$ cat /sys/class/backlight/intel_backlight/max_brightness

Finally, please run this command in a terminal window, then send me the
resulting file /tmp/lspci.output:

$ sudo lspci -vvnn > /tmp/lspci.output

Thanks,

 -Kamal
