Xorg Screen Resolution Problems

Hi, I have a DV9500z laptop from HP with an AMD processor, NVidia Chipset, and an 8400M in it.
But I can't do anything besides the native resolution of 1680x1050.
The open source NVidia driver has no problem doing muiltiple resolutions, but the proprietary drivers can't seem to change my resolution to anything but the native.

Re: Xorg Screen Resolution Problems

Add "Modes fooxfoo barxbar" etc. under Depth 24 (without quotes).

If it doesn't work, post your Xorg log. It should say why it's rejecting the modes you want. If it says something about hsync or vsync, try (slowly! you can break your display) the HorizSync and VertRefresh values (the latter can also be a range, even though it's not set that way in your config). Best would be if you can look up those values for your display.

Another possibility is that EDID is messing with you. Try adding "Option ModeValidation "NoEDIDModes" in the Device section. There's other stuff you can do to disable/tweak EDID, Google for more info. Here's some links, though they may be unrelated: http://www.geocities.com/jgeneedid/ http://www.phoronix.com/forums/showthread.php?t=7893 http://us.download.nvidia.com/XFree86/L … dix-b.html (search for EDID in the text)

Did you try using nvidia-(x)settings to control resolution?

Re: Xorg Screen Resolution Problems

I've added a couple of modes, and I've tried using nvidia-settings to configure the resolution.
Neither of them worked.

Remove the metamodes option, it's making it auto-select from what I can see.
