Google your problem first. Check the Wiki. Read the existing threads.
It's okay to "hijack" an existing thread, yes! If your problem is not yet covered, open a new thread. To get the quickest possible help, mention the exact release codename in your post (uname -a is a good idea, too). Due to the lack of crystal balls, attach the
output of lspci -nnk if you encounter hardware problems.

Went to adjust my screen brightness today, with not much luck. Let me rephrase. It was working as in I was getting the screen brightness applet displaying with the indicator moving appropriately as I toggled FN and right or left arrow. But the brightness was not changing. I was going to post it out, but some searching found the answer. I have tested and it does work. At least for me it did. I have an Acer Aspire TimelineX.
The solution is
Find the line
Comment that out and change it to
Code: Select all
GRUB_CMDLINE_LINUX="acpi_osi='Linux'"
Update grub
And reboot
Hope that helps anyone with an Acer.
I cannot take credit for this except for the fact that I found it.
