nvidia gpu, transfer to nouveau. Can you list the contents of /sys/class/backlight for me please. Hi Ben, here you go: [root@kovinek ~]# ls -lR /sys/class/backlight/ /sys/class/backlight/: total 0 lrwxrwxrwx. 1 root root 0 Jul 8 12:06 acpi_video0 -> ../../devices/virtual/backlight/acpi_video0 lrwxrwxrwx. 1 root root 0 Jul 8 12:05 nv_backlight -> ../../devices/pci0000:00/0000:00:03.0/0000:01:00.0/backlight/nv_backlight lrwxrwxrwx. 1 root root 0 Jul 8 12:10 thinkpad_screen -> ../../devices/virtual/backlight/thinkpad_screen This issue has been proposed when we are only considering blocker issues in the current Red Hat Enterprise Linux release. It has been denied for the current Red Hat Enterprise Linux release. ** If you would still like this issue considered for the current release, ask your support representative to file as a blocker on your behalf. Otherwise ask that it be considered for the next Red Hat Enterprise Linux release. ** Just FYI - brightness keys work properly on F13 xorg-x11-drv-nouveau-0.0.16-7.20100423git13c1043.fc13.x86_64 kernel-2.6.33.6-147.2.4.fc13.x86_64 As the brightness applet is working, it doesn't appear the hw control is at fault. It's probably a problem of getting the brightness keypress through the stack. I'm not 100% sure who's responsible for this, reassigned to Peter as he may. please switch to runlevel 3, then start X with "xinit --". This will bring up X and an xterm. In that xterm, run xev and test if you see any events when you hit the brightness buttons. This will help us narrow down whether it is an issue in X or in the desktop stack. Yup, events are shown (attaching screenshot). Created attachment 439680 [details]

reassigning to g-s-d, the key events are delivered. gnome-settings-daemon doesn't touch the brightness, only gnome-power-manager handles them. I'm seeing this problem on Fedora 14 on a W510 as well. David, can you please attach the output for: killall gnome-power-manager gnome-power-manager --verbose And then pressing the brightness buttons a few times. Thanks.

Hi Richard,
attaching the log. I've pressed brightness-down key twice, brightness-up key twice. Then CTRL+C to quit.
This request was evaluated by Red Hat Product Management for inclusion in the current release of Red Hat Enterprise Linux. Because the affected component is not scheduled to be updated in the current release, Red Hat is unfortunately unable to address this request at this time. Red Hat invites you to ask your support representative to propose this request, if appropriate and relevant, in the next release of Red Hat Enterprise Linux. If you would like it considered as an exception in the current release, please ask your support representative. The issue here is that laptop_panel.brightness_in_hardware is set, i.e. HAL has told gnome-power-manager that the hardware is handling it's own brightness control. This was probably true before nouveau started handling the backlight device. So, the real fix is to fix hal-info to not set this key for the specified hardware now nouveau is new enough to do the right thing. Red Hat Enterprise Linux 6 is in the Production 3 Phase. During the Production 3 Phase, Critical impact Security Advisories (RHSAs) and selected Urgent Priority Bug Fix Advisories (RHBAs) may be released as they become available. The official life cycle policy can be reviewed here: http://redhat.com/rhel/lifecycle This issue does not meet the inclusion criteria for the Production 3 Phase and will be marked as CLOSED/WONTFIX. If this remains a critical requirement, please contact Red Hat Customer Support to request a re-evaluation of the issue, citing a clear business justification. Note that a strong business justification will be required for re-evaluation.
