Fedora 9 is much great. It support my dell 640m notebook very well. But there still have some issues:

(1) In gnome session, I can set the LCD brightness and it works well. But in the gdm login screen, I couldn't find the way to control it. The problem is that, the gdm always turn the LCD to the highest brightness level. only after login to gnome desktop, it tune to the brightness I set.
I tried to set it in gnome powr manager as root user, but not work. And maybe it could would work if I use the following command in rc.local file:
echo n>/sys/class/backlight/acpi_video0/brightness
But each time I logout gnome, the brightness will be tuned to the highest level.

(2) networkmanager have some flaws: I boot fedora with ipw3945 RF switch on, and after enter gnome desktop, I turn the RF switch off. At this time, the wifi would not work, and it will not scan the available AP. Only when I right click the networkmanager and uncheck the first item to disable the network connection, and then recheck that item to enable network connection, the wifi card will now scan the available AP. And now WIFI works very well.

(3) When use networkmanager to control my network, I could not find a way to change the MAC address of my ether NIC. Because the network in my school have IP, MAC and switch physical port binded.
In the past, when use the network service, I can use the /sbin/ifconfig command to change it. But in networkmanager, I can't. Have you any ideas?

These iissues are not critical problems, but if it could be solved it will be much better.

3) There was noises in this forum that they disabled NetworkManager and use Network Services instead.


su -
service NetworkManager stop
chkconfig NetworkManager off
chkconfig network on
service network start
