      So you may have noticed the forum software has upgraded !!!
      A few things that have changed. We no longer have community blogs (was never really used) We no longer have a portal page.
      We can discuss this, and decide whether it is needed (It costs money) See this thread: Here

nVidia 6100 (MCP61V) and Acer AL1716W

Recommended Posts

Just adding this as a tip, as it took me a while to get it to work, and even then it's not 100%...

 

With an nVIDIA MCP61V chipset mobo (on-board GeForce 6100) and an Acer AL1716W LCD, Mandriva 2008, I tried to get it to run in the monitor's advertized 1440x900 resolution. The screen is ugly in that mode and the monitor rwesets to some wierd 1152x870 resolution with the desktop in 1440x900 making it stretched wrong and vertically beyond the edge of the monitor.

 

I got it to work right in 1280x800 with the following xorg.conf:

Hopefully this will help someone else out there. And if anyone knows how to get this combination working in 1440x900 I'd love to hear it.

I think I have a better tip:

The GPL "nv" driver is a big failure. Use the proprietary "nvidia" instead, and I can bet your 1440x900 will show up just great.

Regards.

You are 100% correct. Worked like a charm.

 

Looks like nv doesn't like 1440x900 with those refresh/sync rates.

The "nv" driver is a PITA - this isn't a secret!

Factly, the generic "vesa" driver is faster for me than "nv" in pretty much any puter with an old nvidia card...

But if you are serious about your linux installation and want decent video performance, then you DO have to use the proprietary nvidia driver. Installation is rather easy, if you know what you're doing, and the performance boost is HUGE.

Brian: can you run this command as root at a console:

 

monitor-edid --MonitorsDB

 

and paste the output here?

 

I can then get it added to the detection database for future releases.
