low resolution(startup & shutdown) and brightness issue after installing proprietary nvidia driver

it seems i fixed the startup and shutdown low resolution problem with this http://www.clapico.com/2010/05/02/logo-baveux-ubuntu-dans-lucid-lynx-par-le-joli/

but i still can't control the brightness issue

http://news.softpedia.com/news/How-to-Fix-the-Big-and-Ugly-Plymouth-Logo-in-Ubuntu-10-04-140810.shtml

thx for the answer actionparsnip but i've already fixed that problem in my second post.
the remaining problem is the brightness control(the indicator still works but nothing change while the indicator slides)
i've tried editing the grub file(i forgot the name) to include acpi_backlight=vendor but results nothing
it seems i 've looked this poblem somewhere else while browsing and it says to edit the nvidia configuration file but i forgot what the file is and what to do with it and i forgot where the site is.

Is this a laptop / branded PC

If so can you please give the ful make and model

Thanks

yes this is a laptop
i'm using lenovo y450 dual boot with win7 and ubuntu
ram 2GB
intel core2 duo t6600 @2.2GHz
Nvidia geforce G210M 512mb

Kinda useful information there worth mentioning on the get-go pardener :)

Looks like you need this dudes script:

cd ~/; wget http://elektropionir.net/files/ideapad_brightness.tar.gz; tar zxvf ./ideapad_brightness.tar.gz; cd ideapad_brightness; sh setup_brightness_controls.sh

Should be ok.

the i reboot,
at the startup, i can change the brightness wiht fn+up/down but no indicator
at the login scree, i can't change the brightness with fn+up/down but there's indicator(the indicator changes but no effect)
at the ubuntu, i can't change the brightness with fn+up/down and no indicator

seeing the cd ~; wget http://elektropionir.net/files/setup_brightness_controls; chmod +x ./setup_brightness_controls; ./setup_brightness_controls
are you sure it's setup_brightness_controls??because you said first:
cd ~/; wget http://elektropionir.net/files/ideapad_brightness.tar.gz; tar zxvf ./ideapad_brightness.tar.gz; cd ideapad_brightness; sh setup_brightness_controls.sh
which is ideapad_brightness.tar.gz

now my problem is resolved
all i have to do is just add Option "RegistryDwords" "EnableBrightnessControl=1" in 'Device' section in /etc/X11/xorg.conf
then reboot
it is just in the page 6 of the lenovo forum you gave me.haha
