i just googled a bit and find out that the only solution to increase or decrease the brightness (in fact i need to decrease it, because it is at 100% all the time) was with these commands:

first : find the device address (here 00:02.0)
lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation Mobile 945GME Express Integrated Graphics Controller (rev 03)

second :
setpci -s 00:02.0 F4.B=66 (a value between 00 and FF, where FF is 100%)
