Configuring RHEL4 for ProView Widescreen

JOHN-FM · 06-22-2006, 09:36 PM

I am having trouble configuring Red Hat Enterprise Linux 4 to work with my ProView Widescreen LCD monitor.

I successfully got it working under Ubuntu linux using the following:

sudo dpkg-reconfigure xserver-xorg

Is there any equivalent under RHEL4? Or must I do this manually?

Any help appreciated.

Thanks in advance!

For Red Hat use; sudo system-config-display --reconfigure

Things are a lot better now than they were a day or so ago.

I used to have a 1024x768 screen stretched to 1440x900 proportions.

The only problem is that the resolution I need (1440x900) isn't available as one of my options. They're close, but not quite what I need.

Is there a way I can force the X server to display things properly?

I certainly do appreciate the help!

Well check you /var/log/Xorg.setup.log file and see if your video hardware can support the resolution (1440x900) first. But yes (as root) manually edit your /etc/X11/xorg.conf file, sample section below;

Code:

Section "Screen"
	Identifier "Screen0"
	Device     "Videocard0"
	Monitor    "Monitor0"
	DefaultDepth     16
	SubSection "Display"
		Viewport   0 0
		Depth     16
		Modes    "1280x800" "1024x768" "800x600" "640x480"
	EndSubSection
	SubSection "Display"
		Viewport   0 0
		Depth     24
		Modes    "1280x800" "1024x768" "800x600" "640x480"
	EndSubSection
EndSection

You can also compare your Ubuntu to your RHEL4 configuration for additional clues.

I tried that, and am still stuck with the same 3 or 4 resolution settings I had before.

For my Monitor, I've chosen "Generic LCD Monitor 1440x900" since my particular ProView model isn't listed as one of the available choices.

I think part of the problem is that RHEL4 is not recognizing my video card either, and instead using the generic VESA drivers. I certainly don't have this problem under Windows.

I know it's an nVidia GeForce something or other, but I'm at work at the moment. I'll have to check it when I get home.

I hate Windows and only use it when I'm forced to, and of all the Linux distros I've tried, I really like RHEL4 the best.

I'm just about to trade this widescreen away for a regular screen! LOL

Be sure to read the instructions about the key and using something like apt or yum then installing the nvidia packages are much simpler, for example;

yum -y install nvidia-graphics8762

I think part of the problem is that even the nVidia drivers don't support 1440x900 resolution. Even under Windows that resolution isn't supported. I have to use a special driver package that came with the monitor. I'm now searching for Linux drivers for the monitor.
