opensuse12.1, LXDE: How to configure higher monitor resolution

English Applications
#1

I’m running opensuse12.1 with LXDE. The Monitor Setting (ie lxrandr) show a max screen resolution of 1024x768.

I know that my graphics card can support much higher resolutions. I would like to know what files I need to change in order to configure for higher screen resolutions.

The graphics card I’m using is nVidia GeForce2 MX/MX 400. I would prefer not to upgrade to the latest nVidia drivers because after the upgrade, the screen resolution is set to 800x600.

Are you using the open source nouveau driver, or the proprietary nvidia driver?

Examine your /var/log/Xorg.0.log for any errors or messages concerning your detected display. It is almost certainly an EDID issue. If you want to share the contents of that file, please upload it to SUSE Paste
and post the link to it here.

In anticipation of this, have a read of this thread (there are many others like it if you care to search):

This should be enough to get you started…and maybe solved :slight_smile:

I’m currently using the Nouveau driver.

The /var/log/Xorg.0.log is here: SUSE Paste

Okay, this is what is detected by Xorg

Do you know the specs/model of your monitor? Do you have the choice to use a DVI cable instead?

My monitor is a Dell s2209w LCD monitor.

I do not have DVI connectivity at my graphics card.

Could you help out in how to fix this? What file would I have to modify?

Thanks

Your monitor specs according to

Documentation

1920 x 1080 at 60 Hz

Using the ‘cvt’ utility to generate a modeline gives

cvt 1920 1080 60
# 1920x1080 59.96 Hz (CVT 2.07M9) hsync: 67.16 kHz; pclk: 173.00 MHz
Modeline "1920x1080_60.00"  173.00  1920 2048 2248 2576  1080 1083 1088 1120 -hsync +vsync

See if this ‘xrandr’ approach works for you

Once you have a working display mode, it is easy to make the required edits to /etc/X11/xorg.conf.d/50-monitor.conf and /etc/X11/xorg.conf.d/50-screen.conf

Thanks. Looks like I have some reading to do.
