I'm trying to configure my two monitors correctly with the nvidia driver. The card is a GT520 which drives the monitors correctly using the nouveau driver:

Display-1: DVI-I-1 1280x1024@60Hz Display-2: VGA-1 1280x720@75Hz

Unfortunately, when using the nvidia driver (from the nvidia OBS repo version 304.43) although the DVI connected monitor is configured correctly, the VGA connected monitor is configured to run at 50Hz which results in the desktop extending beyond the physical screen. The nvidia-settings application only gives 50Hz as an option for that display.

I would be grateful for any help or suggestions...

Dylan Dylan,

You don't mention which desktop you're using, but here on KDE 2.8.5 I can adjust my twinview display in System Settings > Display and Monitor. I'm using the proprietary nvidia drivers, not the nouveau driver. The nvidia settings application sets both my monitors to run at 60Hz.

Hi Dylan, My laptop has an nVidia GeForce 9300M GS/512MB. I'm running GNOME 2 with whatever happens to be the latest proprietary nvidia driver. From the 'traditional menu': System Tools - NVIDIA X Server Settings (cli = 'nvidia-settings') The internal laptop display is native 1280 x 800 and set at 60Hz. The external (standard 15-pin analog VGA): 1680 x 1050 at 60Hz. After experimenting quite a bit with this setup -- tenaciously seeking to attain Xinerama heaven, unsuccessfully -- I concluded that certain 'unusual' combinations of settings, such as combining an analog with a digital display while using greatly divergent parameters such as 32-bit color with 24-bit color or 50Hz with 60Hz may simply be beyond the level of sophistication / complexity built into the driver, the configuration software or even the hardware. I was able to find a 'happy medium' compromise, described above, which satisfies both my workspace 'real estate' requirement and my ability to enable/disable the external display at will (for on the road.) I would /prefer/ a 75Hz refresh rate on the larger, external display but when I set it to that (via xorg.conf, not the gui) the internal display goes black. The only other idea I can offer is to confirm that each display is properly identified as to make and model, or, if it's an 'unknown', properly configured. hth & ymmv of course, Carl -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
