Thanks for the bug report.  We have reviewed the information you have provided above, and there is some additional information we require that will be helpful in our diagnosis of this issue.

Please add drm.debug=0x04 to the kernel command line, restart computer, and attach

* your X server config file (/etc/X11/xorg.conf, if available),
* X server log file (/var/log/Xorg.*.log)
* output of the dmesg command, and
* system log (/var/log/messages)

to the bug report as individual uncompressed file attachments using the bugzilla file attachment link above.

Also, I am not sure I understand to “I can’t configure the brightness of my screen”. What's exactly the problem? What have you tried? What have you expected to happen? What actually happened?

We will review this issue again once you've had a chance to attach this information.

Thanks in advance.

Oups, mistake : attachment 488871 [details] 

I meant no brughtness support.

So, what do I mean by that. Well, I can't use my fonction keys + increase brightness keys to configure it nor I can use the standard KDE battery indicator menu with a brightness scroll bar in it to set it up.

Basically, if I start the computer without plugin it, so just with the battery, the screen will be stucked on the economy mode while if the computer is plugged, the screen will be stucked on the perfomance mode.

Per discussion on IRC with devs this is actually a kernel issue. Reassigning.
Comment 7 Aznar 2011-04-02 10:27:26 UTC 
I just tested Fedora x86_64 15 alpha on my NF310. Same issue.

Does this still happen on the latest f15 kernel or the f16 alpha?
