General :: Configuring Xorg.conf On RHEL5 To Support Dual Monitors?
Jan 19, 2010
My Dell Precision Workstation was shipped in 2003 with RH Linux installed (most likely RHEL 4) - though not sure.
At the time, the dual monitors worked by replacing the X86config file with one sent from Dell.
Since, my disk failed and I had to replace the disk and reinstall RH Linux with the shipped disks, RHEL 5.
Now, I can not find X86config; rather, I have been trying to update the Xorg.conf file with no to limited success.
Both monitors are driven off of one Nvidia Quadro FX 1300 videocard. My goal is to get the screen to span both.
Does anyone have a Xorg.conf file that would support this?

Can anyone help with me configure my dual-screen monitors for rotation? I have xrandr 1.1. Have tried various approaches, nothing takes. I can't even get the xrandr options to show up in KDE's Display control panel.
My lspci output: 03:00.0 VGA compatible controller: ATI Technologies Inc RV516 [Radeon X1300/X1550 Series] My current xorg.conf (works, minus screen rotation): # Xorg configuration created by system-config-display
Section "ServerLayout"
Identifier "Multihead layout"
Screen 0 "aticonfig-Screen[0]" 0 0
InputDevice "Keyboard0" "CoreKeyboard"
Option "Xinerama" "off"

fresh install of 11.04 on a built system (frankenstein leftovers), 2.something ghz, 1gb ram, a host of drives, and a 64mb nvidia mx440 with svideo out. Boots up, looks pretty, something about unity not finding 3d graphics (fine, i don't really want it, just more fancy gui crap to suck cpu cycles) and runs fairly well. so I think, cool, svideo out, old 52" rear projection....HTPCish. "Lemme get this thing hooked up to the tv, what a great idea" So, I start looking around and find all kinds of wrong posts about not Natty, and not my video card, and I try this n that,and it doesn't work. I'm all about reading the forums, but I can't find the right info for my sitiation, and I'm overwhelmed/irritated.
Long story short, I added some repository ppg something, and then dl'd and installed the "nvidia-current" driver. After a reboot, I fire up the nvidia gui, and it tells me I have no xorg.conf and to run a particular command in terminal to make one. So I did it. and after another reboot, my system just hangs at "ubuntu" with the four (five?) dots. Reboot, recovery, something something something, safe graphics, backup your xorg.conf? yes. reboot and all is ok now. still no nvidia support. Now I'm reading the internet machine about the xorg.conf being old school, and how I have to make a monitor.conf file with config settings. only problem is it tells me to go to x11/xorg.conf.d/whatever. I have no xorg.conf.d directory. So what's the deal? How in the hell do I get the nvidia driver installed (I think I got that), configured (I have no clue), and running (yeah, I just saw a flying pig)?

I have a dual monitor setup (Twinview), both monitors are connected to my 1xNvidia MSI NX8600GT card...I've been using a 21.6inch HannsG HG216D (herein referred to as HG216D) monitor as my LEFT monitor, and a Dell 1905fp (herein referred to as 1905fp) as my RIGHT monitor.
I recently got rid of the 19inch 1905fp Dell monitor and moved my HG216D to the RIGHT and now I have a new 23inch DELL S2309W (herein referred to as S2309W) on the left. The new S2309W is connected to my computer via DVI cable and is configured Perfectly at it's native 1920x1080 resolution.
However I can't for the life of me get my HG216D back to it's native 1680x1050. The HG216D is connected via VGA cable that is also routed thru a KVM, I realize this means that this monitor can't/won't be auto-configured. However I should be allowed to set it manually right?...
Code:
Won't let me select 1680x1050 for the HG216D resolution, it will only let me select 1440x900 MAX, there is no option for 1680x1050, (See attached: screenshot)
I've tried to manually edit my /etc/X11/xorg.conf, but after hours on end messing with it, I give UP...
Here is my current xorg.conf:
Code:
I am just not sure what I need to change and how to get the second xorg.conf to play nice via a VGA connection?

I am having some real problems with my dual monitor setup in Centos 5.6.I am trying to run 2 individual monitors like span say the whole desktop over 2 monitors say, using the Admin>Display (I think it's that menu, sorry working from MS Windows at the moment).But everytime I set them up perfectly, every time as it requests you do reboot your computer once the changes have been comitted (written to presumably the xorg config file), the whole Window X Server? it crashes.
Any suggestions as to what to do? I am using an Nvidia Gefore 9600 GSO 768Mb RAM graphics card on it, using one DVI monitor and then an old CRT, but surely it should be the software or even the drivers that are causing the problem.I mean I could just put up with having one monitor but it really bugs me, as I prefer to have one screen for my research and one screen for my production work so to speak.Also I am running an AMD processor +4400 to be exact

I just downloaded Ubuntu 10.10 and installed it today. I was just wondering, does Ubuntu support dual monitors? I tried looking through the settings in Ubuntu but I couldnt figure it out.

I've just done a fresh install of Lubuntu 10.10 on an older Sony Vaio laptop. Having learned the hard way about editing xorg files, I wanted to create a backup of the xorg.conf file so that I dont have to do another install when I screw everything up. In a terminal, I typed

I have installed Kubuntu 8.04.2 on a USB stick with persistence to keep any changes I make after a reboot and it works fine. I then installed the 185 Nvidia driver to give me higher resolutions and it works fine.
But each time I reboot, my updated xorg.conf is replaced with the default xorg.conf that ships with that version of Kubuntu and a backup is made of my updated xorg.conf (the correct one) which looks like xorg.conf.20100409135913. I have to put the backup xorg.conf back in place to get my Nvidia driver to work with the correct screen resolutions again. Otherwise my screen resolution is too low.
What could be causing this behavor? I'm sure it not the persistence feature of the USB stick failing since a backup is made of my original xorg.conf.
I might add more information. The xorg.conf that gets changed after a reboot says "This file was generated by dexconf, the Debian X Configuration tool, using # values from the debconf database." #

I've read the how-tos (thank you oldcpu!) and wikis about how xorg.conf take precedence over the section configuration files in etc/X11/xorg.conf.d/, if it exist. I also understand that the xorg.conf can be partial. If it is missing some sections, these will be taken from the corresponding xorg.conf.d section config file. Currently I'm using a xorg.conf generated by nvidia-settings in one of my home machines, due to a dual-monitor setup. After generating xorg.conf, the device sections are:
in xorg.conf:
Code:
Section "Device"
Identifier "Device0"
Driver "nvidia"
[code]....
My question is if the Option "UseCompositeWrapper" "True" will be used or not. In other words, if a section exist in xorg.conf then it's correspondent in xorg.conf.d/ will be completely ignored *or* only the lines in xorg.conf.d/ that already exist in xorg.conf will be ignored?

I'm running the ubuntu based Green OS and cant get my video card properly configured. i've already gone through the forums to figure out what i need to do to get my ATI card working but my system wont let me access the xorg.conf file. i can see it using the the GOS file editor but it wont let me save the modifications. when i attempt to edit from a terminal window with su privelages it tells me that /etc/x11/xorg.conf does not exist. i've even tried booting into recovery mode and using the root instead of the sudo command. nothing i've tried will let me open the file.

my laptop screen has 1900x1280 (native resolution) and my second monitor has 1600x1080
After browsing the forums and messing around with drivers I managed to get the resolution up to 1600x1080 (from 1000x800 at install) on the laptop screen. No luck at all with the second monitor. I currently have it connected with both VGA and DVI.
my understanding is I need to use twin view to setup the second monitor. I've read several of the earlier posts but haven't been able to get it to work. Here is my current xorg.conf file:
Code:
Section "Monitor"
# HorizSync source: edid, VertRefresh source: edid
Identifier "Configured Monitor"
VendorName "Unknown"

I just abandoned Windows 7 for Ubuntu. I am trying to setup my monitors on my desktop. I have 3 monitors (i have 2 graphics cards with 2 monitors per graphics card -- so potential for 4 monitors).
Currently I have 2 of the monitors working, but they only mirror each other. I tried going in to System-Preferences-Monitors to configure them the way I want to, but nothing i do stops them from mirroring each other.

This is a repost of my initial problem, I need some one who knows what they are doing more than I too take a look at this command output and give some sort of direction/clue/etc on what I'm doing wrong or missing.
Is my xorg.conf missing some vital line(s) or setting?
My best guess is that i'm missing something to tell the Xserver to use both screens, as the Xorg.0.log does not talk about trying to bring up the intel display; but this is just a hunch.
I'm running kubuntu 9.04 with 2 monitors: on-board intel video and a PCI nvidia display: I am using my nvidia display fine, but still can not get my 2nd display (the intel) working. What the heck am I missing?

I have used nVidia my entire linux life (about 5 years clean and sober from M$). Recently, I have switched over to an ATI Radeon HD 5550 card. After many trial and error setups, I finally got the resolutions and screens set properly with a xrandr command, which I have now added to a shell script in ~/.kde4/Autostart. It has worked for me for a while now, but I really would like to get it set in the xorg.conf.d files so that I don't have to wait that extra few seconds after login for the screens to fix themselves.
Is there an easy way to take what xrandr does and export it to the xorg.conf.d files? If my video card recognizes my default monitor as DFP2 and the tv that I only sometimes use with this computer as DFP1, how can I ensure that the login screen for openSUSE/KDE4 appears on my default screen (an issue that drove me nuts a few months ago when I tried Ubuntu to see what all the fuss was about)?
My xrandr command that I use to fix it all is:
xrandr --output DFP2 --auto --pos 0x0 --primary --output DFP1 --auto --right-of
I am using the proprietary Radeon driver from the ioda repository. DFP2 is a monitor which has a optimum resolution of 1920x1200, and DFP1 is an 1080p HDTV. I can not reverse the output plugs for the screens even though my monitor is an HDMI monitor because I use the actual HDMI port on the video card to output audio to the television and the other plug is a DVI that I convert to HDMI for the monitor.

I have created lvm snapshot, its dd file and .tar.gz files are on lvm volumes. Snapshot is of / directory, is residing in lvm volume. The root directory is also lvm volume. So I was trying to restore from snapshot of / using live cd of rhel5 BOOT.iso. which i found it in /rhel5_dvd/images/. The tutorial I was following said that the live cd should support lvm. So when I am trying to restore after few steps when it asks for media which contains rescue image, I was unable to see the lvm volumes created earlier, instead it shows the partitions added to physical volume earlier i.e., #pvcreate only. So I wanted to know whether the live cd of rhel5 supports lvm or I am making some mistake in restore?

how is the support for multiple, two or more, monitors in ubuntu (10.04) when using a graphic cards from AMD(/ATI), for example the HD 5770. (Which I'm currently using). I know that DP is required to use three monitors on a regular card. But other than that, will it work? Am I to expect a lot of work to be able to get it working? Or will it simply be impossible? (And yes, I know that AMDs(/ATI) drivers aren't always the best... Although changing to a card from nvidia at this moment isn't possible)
The background to my question is that I'm thinking about buying another monitor, same model as the current one I'm using, and later on perhaps expand to buy another one.Tried to search for it but wasn't able to find how the support would be in linux, and ubuntu in particular, since most I found is about the windows support, which should work quite easy and therefore isn't relevant.

Is it possible to add more than one graphic device driver to xorg.conf and it will load automatically? It is important to autodetect because I am using the configuraiton read only. This is because it's a custom LIVE CD.This is what I currently have, and it works!
Problem is if I put my Live CD in my brothers machine, it fails to load because it uses a Radeon driver!I can preinstall the ati packages I need, so all i need to know is how do I make it work?

I am using Linux 2.6.29-020629-generic #020629 SMP Tue Mar 24 12:03:21 UTC 2009 i686 GNU/Linux ubuntu.
I have a widescreen lcd laptop and the current resolution is set at 1280x768 pls see output of xrandr here for more information [url]
I want to change the resolution to 1024x768. I can do in ubuntu' display tool. The problem is that once I change it, the output does not take up the whole screen it has blank spots on the left and right side
For a better understanding please have a look at [url] and [url]
In open suse the system sets it at 1024x768 without any blanks on the left and right corner. You can have a look at it here [url].
My current xorg.conf is details is at [url].
Please also find my xorg.0.log at [url]

I have just started to work with BeagleBoard and built the Linux kernel (version 2.6.30.5) and download to the board and it start. I have also connected to the board over serial to Putty terminal.
Now I want to connect to the Beagle Board using USB instead of serial and I am looking for some info on how to do this.
My goal would be to connect to board over USB and then be able to:
* Download my own binary files/programs from PC over USB to BeagleBoard
* Communicate over USB instead of UART/Putty to get log and execute commands
Question:
How do I build the Linux kernel with USB support, meaning what settings should be ticked in menuconfig? Or is it already included?
How do I enable USB OTG in menu config?
I assume I would need some driver on my PC with Windows XP to connect to my BeagleBoard over USB. Were can I find this USB driver?

I installed the latest nVidia drivers on my laptop using the 9800M card. The laptop is a Gateway P-7805u and I'm connected to the second monitor using VGA.Also, before installing the nVidia drivers (and just using the basic drivers included with Kubuntu 10.04), basic dual monitor support worked, except I could not enable compositing features for some reason. So I thought the proprietary drivers would fix this.Several issues have arisen since installation:
1) I've clicked through all of the display settings to activate the second screen with absolutely no change.
2) When I try to apply settings and Save Configuration as the nVidia help suggests, I am told that I cannot save to the X.conf file. I assume this is due to innate permissions on my user settings, which I have no idea how to properly configure.
3) I have no idea where to go from here, as most of the fixes I found online involve Linux syntax and verbiage, to which I'm totally clueless after spending over half my life with Windows.

Been trying to setup my xorg.conf file to have a 1920x1200 screen.Strange behavior: when my X starts up, I see my mouse cursor, can move it around. It's small enough to suggest the 1920x1200 resolution took, is working.However, the rest of the screen remains black. No login prompt.I've looked at /var/log/xorg.conf, no errors.Is there something else I can look at?

I have set up my Ubuntu virtual machine and am trying to adjust the screen resolution because it's stuck at 800x600 presently and there are no higher resolution options. I've looked at numerous similar forms and tutorials online and they all seem to involve editing /etc/X11/xorg.conf. However, for whatever reason, this file seems not to exist on my machine. I found another tutorial on how to add a screen resolution using xrandr --addmode which added the resolution I want to the list that appears when I type the command xrandr, but when I try to apply it I get an error about CRTC 262 failing.
