View Full Version : [ubuntu] Resolution problem?

July 14th, 2008, 09:34 PM
My screen resolution I can't get it more than 800 x 600 with everything I keep trying.
I have:
nVidia [Quadro4 750 XGL]
ViewSonic P225f

I'm using the restricted hardware drivers, which seems to be glx

I've tried so many things, which I ended up having to reinstall everything a few times, but

Here's the output of xorg.conf

# xorg.conf (X.Org 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 manual page.

Try installing and running envyng-gtk and envyng-core - that helped me.

sorry I should have mentioned I tried that already, tried it automatic, then manually and selected all three options. Spent a lot of time trying to get it working and the best I could get is 800 x 600 and once I was able to get other options with worst resolution, but nothing better.

Really not sure what to do.

Guess what I would do is scour the net for any and all things about nVidia [Quadro4 750 XGL] and Viewsonic combination. Surely someone out there has made that combo work.

You can also post on Alberto Malone's blog.

Have you tried running nvidia-settings? It's in the repos if you don't already have it.
You can configure your resolution from the X Server Display Configuration section.
Run it as sudo from the command line to make your changes permanent. (Save to X Configuration File" option)

yeah, I tried the nvidia settings

The closest seems to be using https://help.ubuntu.com/community/FixVideoResolutionHowto

which when I do :

sudo dpkg-reconfigure xserver-xorg

When I reboot it says it's too low resolution and asks me to configure it. The problem is that the driver that was from restricted driver isn't in the list. I then tried to go back and manually edit xorg but still no luck :)

actually installing linux on a friend's computer and he's starting to get disappointed, so I'm hoping to get this up and running soon I hope

I don't know that much about it but that looks like a real high-end graphics system.

If you have an LCD monitor that you could temporarily try with that Nvidia card it might be interesting to see if you would get a higher resolution to work. I also think there is an xorg option to tell the driver not to read the info from the display when generating the xorg file but I don't know what it is.

well I tried it with the framebuffer on and off.......

I do believe I have a dell LCD laying around, but I'm going out of town, so I can't try it now until Monday, but I'll give the LCD a try to see if that's the issue and that it's not the video card.
