Nvidia driver via 1-Click results Screen Brightness problem

English Hardware
1

Hello,
I installed latest NVIDIA driver via 1-click (NVIDIA - openSUSE) to my laptop’s (HP EliteBook 8530w) graphic card (Nvidia Quadro FX 770M), but it results no adjustment on screen brightness with power management console. However, before installation the driver, it was ok with MESA drivers which comes after the installation of opensuse 11.1 64bit (KDE 4.2.3).

Do you suggest me to install the Nvidia drivers from Nvidia’s official website? IS there any other way to fix it? I also modified my xorg.conf to add " Option “AllowDDCCI” “1” " which allow to communicate onscreen buttons with graphics card.

It’s possible that the latest stable driver (what is actually a bit old) doesn’t support that - you should try to install beta (185.18.10 is never then the 185.19!) drivers.
The screen brightness doesn’t work work me too in the KDE widgets, but I think it’s rather a KDE bug the a driver.
Good luck.

Hi, I downloaded the drivers under the title of “Linux, FreeBSD, and Solaris Drivers” at the official nvidia website.Normally, if yoou select your driver via drop down menu filter system, it results a driver has a version NVIDIA-Linux-x86_64-169.12-pkg2.run. if you download the beta drivers, it results a version NVIDIA-Linux-x86_64-171.06-pkg2.run. But if you browse to “Linux, FreeBSD, and Solaris Drivers”. and select Linux AMD64/EM64T, it results the version NVIDIA-Linux-x86_64-180.60-pkg2.run, which has solved my issue. The funny thing is, if you use 1-Click Nvidia drivers, its version something 185.

Then I’m sorry. I’ve downloaded this driver through the 1click a long time ago. I’m always using the latest beta driver from nvidia’s FTP:
ftp://download.nvidia.com/XFree86/.
Glad to hear that it’s solved your problem.
