hello i have a nvidia GeForce Go5200 in my laptop (toshiba ).
next to the laptop display i used the vga output to plug in a 2nd monitor.

In order to do so I updated the kernel sources, installed the proper drivers and switched to twinview. but since i have installed the nvidia drivers the screen of my laptop got really dark it is almost impossible to read anything. I tried all settings within the nvidia control panel and by clicking on desktop > configure desktop. which lighted up my screen a lil bit but still way too dark.

I used to have a .exe under windows which allowed me to manually configure the darkness by using the FN+F7 if you need any further information about my hardware tell me what and i ll post. thx 4 help
