Hardware :: Can't Configure Stable Xorg.conf For Triple Head
Aug 25, 2010
I currently have 2 GPUs in my system both ATI. The primary is a HD4870 and the secondary is a HD4350.
I have a 24" and a 17" running in twin view from the 4870 but I can't figure out a way to enable my third monitor to display anything at all, I have tried multiple configurations but I end up breaking the xorg every time.
All I simply want to do is keep my twinview on the monitors run by the 4870 but have the third monitor as a separate X session so I can still use compiz. Here is my xorg file, it was generated by aticonfig.
Code:
Section "ServerLayout"
Identifier "aticonfig Layout"
Screen 0 "aticonfig-Screen[0]-0" 0 0
EndSection
[Code].....

Anyone experience with multiseat configuration in combination with openSUSE 11.2. Looking for a howto since we don't use xorg.conf to configure X and everything is autodetected by HAL.

I have a wacom graphire3 tablet and two monitors. The tablet is workin properly with out of the box drivers.
As well as the dual monitors configured as twinview through Nvidia X server. But the tablet is mapped for the two screens, then I searched the forums for a proper configuration and it it tells me to edit the xorg.conf file for twinview horizontal but, it don't make any difference. I've "sudo gedit" edited the xorg.conf and nothing happens. Nothing, the tablet is working properly, the system is stable and it's still mapped for two screens.
What can I do? The xorg.conf also isn't listing all my hardware, I can't see the confs for my mouse. I'm on karmic koala.

All I need to do is get my screen resolution to 1024x768, I can currently only get 800x600 and that's unacceptable for school. I created an xorg.conf file in Lucid and it does in fact refer to and use it. what led me to believe that is when I looked in the mirror and noticed smoke slowly rolling out of my ears! After replacing some of that smoke with a cigarette I decided to make this thread. As I said, I created the xorg.conf.new file with:
Code:
sudo Xorg -configure from recovery mode. And then moved it to its proper place with:
Code:
cp /home/william/xorg.conf.new /etc/X11/xorg.conf
And that nested it right where it needs to be. X does in fact use it as confirmed by my Xorg.0.log.
Now I have an xorg.conf file, but am quickly becoming overwhelmed with information as to what to do. I've tried to create mode lines with xrandr, which gave me new settings, but I was unable to use them. Obviously the EDID info. is not being read because there is no mention of clock speed, Vsync or Hsync in my Xorg.0.log either. I have tried many things and really don't have time to spend all day at my computer, at least not with this issue. I'm in school and have to focus primarily on that right now. I will give what info I know is relevant starting with my monitor specs:
Dynex DX-LCDTV19
vertical resolution: 720 p
aspect ratio: 16:10
screen refresh rate: 60hz
comb filter: 3D/YC digital

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 did fresh install of Slackware64 ver. 13.0 and immediately updated it to slackware-current by following the directions here: http://slackwiki.org/Upgrading_SlackwareSo far all is normal and functional except for xorg-server.When I did Xorg -configure under ver.13.0, it worked perfectly and detected my nvidia 8800 GTS vidcard and 1440 x 900 lcd monitor.However, after upgrading to "current" and xorg-server-1.9.4, I'm getting a segmentation fault and cannot configure a working xorg.conf.I've been searching xorg seg errors, but haven't found a solution yet.My /var/log/Xorg.0.log:

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." #

1. What is the difference between files (xorg.conf and xorg.conf-vesa)
2. No matter how hard I try I can't change keyboard layout in xorg.conf-vesa (I change it in file ) but there is no actually anything changing, it starts to get annoying - for example - below goes my xorg.conf-vesa, if I uncomment and set line from

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.

I have a GeForce 8400 GS card and I run two monitors. I use Xinerama (don't recall now why but I think XrandR didn't work for me) and nvidia. I would like three monitors now and I see here[URL].... My onboard video is disabled by the mobo if I use a video card [URL]... so it seems I need a new video card.
Should I get another GeForce 8400 GS for $40 from Amazon? I suppose the only other idea would be to get a 3-head card but those seem a lot more expensive.

I have been trying to figure out if Eyefinity will work in Ubuntu 10.04 for three monitors. I can test this at work where we have three monitor, one with a display port connection. I just want to know if it is worth trying, and if so what catalyst drive might work.
So I have done a lot of searching and have found a number of yes and no answers.
To start with Lanchpad has a change log saying it should work.
[url]
This guy says it work once did but does not now.
[url]
Then someone tries and fails with Catalyst 10.6. Seem like a lot of other good info here.
[url]
Then to finish it up these guys have some rumors that seem to say Catalyst 10.7 will support this.
[url]
I think I will wait for Catalyst 10.7 and then give it a try.

I'm trying to get rid of my dedicated media center and connect my desktop to my TV instead. No matter what I change I get no picture at all on the TV when connected to the desktop. I already have two LCD monitors using nvidia's "TwinView" mode and I want the TV to just be an extension of this, at a lower resolution.
My system information is below, but note that anything in the tag " ### NEW {}" in the xorg.conf is my attempt at getting this to work, the rest was already there. Two LCD monitors are screens 0 and 1, the TV is screen 2.

Yesterday I updated my F15 x86_64 system from kernel 2.6.38.6-27 to 2.6.38.8-35. After the reboot, my triple-head system complained of not having enough CRTCs and only 2 screens worked. Other components were also updated, including some X11 components, however selecting a fallback kernel at the grub prompt indicates this follows the kernel (fall back to old kernel has all 3 monitors working). xrandr --verbose on the 2.6.38.6-27 kernel shows each of the 3 monitors assigned to separate CRTC entries, with CRTCs 0 thru 5 available.
Same command on the new 2.6.38.8-35 system only shows CRTCs 0 & 1 available. My system using an XFX Radeon HD5450 card, with 3 interfaces: HDMI, DVI, VGA. The default Fedora open source "radeon" driver allows all 3 interfaces to be usable. However, with the new kernel, the loss of several CRTCs prevents the 3rd monitor from working.What are the thoughts from the community? I've searched various forums here and haven't seen similar symptoms reported. I'm looking for any direction/experience/thingsToTry from others before trying to open a bug report. (Attempts to use the Catalyst driver several months ago resulted in only 2 of the 3 connected monitors working.

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.

Alright setting up a friends netbook, display has been a little iffy (slow. glxgears is giving like 100fps). Couple issues: xorg.conf doesn't exist (i know thats typically not an issue) and "sudo xorg -configure" and "sudo xorg --configure" both return "xorg command not found."
glxinfo say that its using Mesa for the software rasterizer and that the driver is from mesa. lspci says the VGA controller is from Intel. I'm thinking xorg is defaulting to vesa for drivers, but I need to know how to change that to the open source intel driver

I'm trying to set up a tri monitor setup. Unfortunately I must use 2 cards, one an AMD HD4350 and a PCI Geforce FX200. (Old skool I know) Due to the restrictions, I am forced to use the open source drivers (else nvidia glx will clash).
1: Use XRANDR to span the displays (this is what I did previous to the introduction of the third monitor and nvidia card to my system) I tried to do this, by setting up a second X screen on the NVIDIA card, disabling Xinerama; but after much googling I can't figure out the syntax for panning across 2 screens (X screens) in XRANDR, even tho it's >1.3, which supposedly supports multi card output.
2:Use Xinerama, sacrificing randr, and composite extensions. I also attempted to do this, with some limited success. I could get the NVIDIA screen to be right of the ATI, but I couldn't get 2 independent outputs running on the ATI card, even with "ZapohHeads" appended to one of the device sections for my ATI card.

Sorry if this was well covered here when most up-to-date Slackers moved to 13.0, but I have just jumped from 12.1 to 13.1. Generally very happy that I do not have to think about xorg.conf as I always found the structure of this conf file a tad confusing. However if I do need to (for example) change my video driver (I might for example want to try the nvidia driver from NVIDIA) or configure my touchpad - how do I do this ?
I understand that xorg.conf can still be created. If I do so, do I have to put all the stuff in that used to be there or can I just add the stuff I need to make the changes I am looking for?

I just did a net install on an old powerpc G4 and it seems pretty successful.except i cant change any of the monitor settings from the control panel in gnome (or LXDE)its showing 'not recognised' and only allows 768 x 1024 in very restricted colour.I dont think there is a hardware problem:
- the monitor is a generic old CRT which has worked fine with everything before this.
- the display card is an AGP 32Mb - original with this G4 and was working.
- the computer works great in Mac OS10.3 - (but OS10.3 doesnt support flash or up to date web browser any more, hence trying debian).
i have searched debian forums and various sites, but i couldnt find a fix. It looked like i should edit xorg.conf file but I am not able to find it. I looked in /etc/X11 - but not there.could someone tell me please, do i need to find xorg.conf?

I am running Crossover Office on a laptop on OpenSuSE 11.2 with a fair bit of success (Outlook is still twitchy related apparently to the http stack). But whenever I do disk I/O to a windows app and I have a second monitor plugged in it flashes to black.
In prior OpenSuSE versions I used to be able to stop this by adding entries to disable the TV output in xorg.conf but now it appears that there is no xorg.conf in use. How do I disable this in the post-sax2 era?
