Description Josh Boyer 2007-10-31 10:16:25 EDT
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):


How reproducible:


Steps to Reproduce:
1.  Boot
2.  Try using the FN+Home, FN+End buttons to switch brightness in X
3.  Watch nothing happen
Actual results:

The backlight brightness doesn't change

Expected results:

The backlight brightness changes

Additional info:

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.

Comment 4 Josh Boyer 2007-10-31 13:40:32 EDT
I don't have an /etc/X11/xorg.conf file.  They aren't needed in rawhide/F-8
Comment 5 Josh Boyer 2007-11-11 21:26:11 EST
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.
Comment 6 Josh Boyer 2007-12-03 22:13:28 EST
This is still present in rawhide:

[jwboyer@vader ~]$ rpm -q xorg-x11-drv-ati
Comment 7 Josh Boyer 2007-12-20 11:48:34 EST
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 ;)
Comment 8 Matěj Cepl 2007-12-20 18:23:42 EST
OK, let's put this into NEEDINFO, so we won't forget about that, right?
Comment 9 Matěj Cepl 2008-01-21 10:23:11 EST
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.
Comment 10 Josh Boyer 2008-01-21 14:25:21 EST
Yep, sorry.  I think we can close this out.
Comment 11 Josh Boyer 2008-03-10 09:45:50 EDT
This is back now.

Comment 12 Josh Boyer 2008-03-10 11:43:17 EDT
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.
Comment 13 Josh Boyer 2008-03-16 20:32:46 EDT
Ok, whatever.  This is fixed with the latest kernel.  /sys/class/backlight is
still empty, but *shrug*.
