Description of problem:
On my Thinkpad z60m the FN+Home and FN+End buttons control the brightness level
of the backlight. A couple weeks ago this stopped working. I press the key
combos and nothing happens.
I did some bisect of kernels to see if that was the problem, but it wasn't. I
switched to using the vesa driver instead of the radeon driver and the
brightness key combos worked again.
Then I did a brief bisect of the xorg-x11-drv-ati packages and found that
xorg-x11-drv-ati-6.7.195-2.fc8 worked but xorg-x11-drv-ati-6.7.195-3.fc8 did not.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
2. Try using the FN+Home, FN+End buttons to switch brightness in X
3. Watch nothing happen
The backlight brightness doesn't change
The backlight brightness changes
The brightness key combos work at the grub menu, during kernel boot, and on
vttys but not in gdm or X sessions using the latest radeon driver.
Just to be sure that we get info about your hardware correrct, could we get
/etc/X11/xorg.conf and /var/log/Xorg.0.log as well attached to this bug as
separate uncompressed attachments to this bug (sorry, smolt is not that helpful
for Xorg bugs)? Thank you.

I don't have an /etc/X11/xorg.conf file. They aren't needed in rawhide/F-8
Anything I can do here to help this bug? While reverting to the previous
drv-ati RPM works, F8 was released with the broken one so it would likely be
good to get things fixed.
This is still present in rawhide:
[jwboyer@vader ~]$ rpm -q xorg-x11-drv-ati
Ok, this seems to be fixed now. Relevant packages:
Since this is magically fixed today, I think I'll leave the bug open for a bit
longer in case tomorrows update magically breaks it again ;)
OK, let's put this into NEEDINFO, so we won't forget about that, right?
Reporter, could you please reply to the previous question? If you won't reply in
one month, I will have to close this bug as INSUFFICIENT_DATA. Thank you.
Yep, sorry. I think we can close this out.
This is back now.
Other relevant package versions:
/sys/class/backlight is empty. I'll try and see if a kernel can be found that
works with this and check if there are entries in there. If there's more I can
do to help debug, let me know.
Ok, whatever. This is fixed with the latest kernel. /sys/class/backlight is
still empty, but *shrug*.
