HOWTO: change resolution/refresh rate in Xorg

[Gen2ly]

Nice tutorial. Just in case you update this still, modeline can also be discovered with:

gtf x y refresh

Thus far I am not having any luck. I have a Dell E1505 laptop with an nVidia Go7300. I am trying to get to 1680x1050 @ 60hz but cant seem to break the 1024x768 barrier. I've been searching these forums as well as Google for a couple of hours now and have found some excellent advice but sadly none of it seems to be working for me. Can someone assist me please? Thank you in advance

Were you able to select 1680*1050 resolution during configuring;
sudo dpkg-reconfigure xserver-xorg?

What does "sudo gedit /etc/X11/xorg.conf" tell you, in section " screen"?
Once you've configured xorg it should list the resolutions you've selected.

Hi Zed,
Yes, 1680x1050 was available in configuration and I hit the space bar to make sure it was selected.

This is my Xorg file...

# /etc/X11/xorg.conf (xorg X Window System server configuration file)
#
# This file was generated by dexconf, the Debian X Configuration tool, using
# values from the debconf database.
#
# Edit this file with caution, and see the xorg.conf(5) manual page.
# (Type "man xorg.conf" at the shell prompt.)
#
# This file is automatically updated on xserver-xorg package upgrades *only*
# if it has not been modified since the last upgrade of the xserver-xorg
# package.

# If you have edited this file but would like it to be automatically updated
# again, run the following command:
#   sudo dpkg-reconfigure -phigh xserver-xorg

I also want to add that I am currently @ 1280x800 @? refresh rate according to Nvidia settings.

[en3rgy]

Anyone?

[zedfrugnug]

Very strange. Maybe it's a bug??
Laptopsupport is getting more attention, so maybe things will work better for widescreens when Gutsy arrives.

Where did you find " nvidia settings"?
And what about preferences > screenresolution?

[frodon]

en3rgy, try to add the modelline of the wanted resolution if nothing else works.

Hi again Zed,

The Nvidia settings I found are located under APPLICATIONS>SYSTEM TOOLS>SYSINFO>NVIDIA.

As far as preferences goes, this is a joke. It says 1280x800 but then tells me I'm @ 50hz refresh rate.

I've posted this problem of mine in other threads too to see if I could get some help with this and thus far this problem seems to be stumping everyone.

The E1505 Dell laptop has the upgraded screen and came with XP (which I am duel booting with Ubuntu). In XP my max (and only) screen size is 1680x1050 @60hz and it really looks wonderful.

I have installed Ubuntu on two other PC's I have and so far all of them work really well except for the video. Then again, they're all Nvidia boxes so I am wondering if Nvidia actually is not very good to begin with and Ubuntu forces this imperfection to come out?

Either way, I am almost demoralized at this point and am not sure what to do with this video/Nvidia problem.
