Hello all!
I am using Ubuntu Hardy Heron (installed when it was still beta), on an
"ACER Aspire 5102WLMi" laptop.
Laptop information:
$ sudo dmidecode -s system-manufacturer && sudo dmidecode -s system-
product-name && sudo dmidecode -s system-version
Acer
Aspire 5100
V2.40
The problem is that I cannot increase the bright normaly when I am in
Gnome. If I increase the bright at maximun at login screen (gdm) or
during the boot, the screen brights at maximum. If I change the bright
during the previous situations, I can return to raise it to the maximum.
When I'm in Gnome (and "gnome-power-manager" is working), if previously
I have put the bright to the maximum, then it remains at 100%. On the
other hand, if I push the bright-down key (Fn+Left) or the bright-up key
(Fn+Right), the lcd panel can be only at 70% of bright at maximun.
When I do the previous, I cannot increase the bright to 100 % until I
return to the login screen (gdm) or during the system-boot.
If I put in the console the following...
$ killall gnome-power-manager
... The problem disappears and already I can change the bright normaly
even being in Gnome.
I leave more information, it could be helpfull:
$ cat /proc/acpi/video/VGA/LCD/brightness
Levels: 70 40 0 10 20 30 40 50 60 70
current: 70
As you can see, the maximum value is 70. And the current, yet having
"gnome-power-manager" disabled and with the bright at maximun, stays at
"70".
This also was happening in Gutsy.
PS: Sorry, but my english isn't the best.
Goodbye!
