Ubuntu :: Switching Between Two Xorg.conf's?
Jun 6, 2010
I've got an i5 Macbook Pro, on which I've got Ubuntu 10.04, which I use 90% of the time (mainly for work).
I've added a few lines to xorg.conf to make the graphic card run cooler and thus get some more battery life. Sometimes, though, I do need full graphic potential, for which I have another xorg.conf prepared without those lines, so I can switch back and forth when I need it.
Currently, to change back and forth, I rename the files accordingly and reboot, which is a pain in the neck. I tried restarting gdm after switching files instead but it didn't quite work (maybe I wasn't doing it correctly).
So, fellow experts, what's the easiest and fastest way to switch between two different X11 config files?

I want to switch between my monitor in my office and a hd-ready TV in my living room which is connected via DisplayPort/HDMI. So I wrote the following script (called by nohup and the number for the desired config-file is given as an argument):
Code:
This basically works but I have two problems:
1) All currently opened Windows are gone after restarting X. So I need a more elaborate script
2) I cannot get the right configuration for my TV. The manual recommends 1280x768_60. This mode doesn't seem to be supported (xrandr doesn't list it).
Until now I use the following xorg.conf for TV:
Code:
With that configuration about 20px of each side of the desktop are hidden. The TV also displays an info that the signal is 1080i. The refresh rate is set to 50 instead of the desired 60. I tried to force 720p by adding the line Modes "720p". The rest of the file was mostly generated by the nvidia-driver.
So what can I do to: Keep my opened Windows when switching Displays See the whole Desktop on my TV and set the refresh rate to 60

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." #

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'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'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 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've just installed the latest ubuntu (10.10) on vmware workstation and noticed the resolution is not 96 dpi so my fonts look a bit unsharp
I wanted to change that and noticed I don't have an /etc/X11/xorg.conf? So my question is of course...where should I put the "Option..." line to change it to 96 dpi?

My Audio stops playing when switching to console from Xorg. When I switch back it continues playing. Is it supposed to be like this? Any way I can make it play continuously? I've already checked the Howtos and this forum for this problem but havent found anything similar.

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?

Thinking to be clever, I made some changes to /etc/X11/xorg.conf and now I cannot see anything on the screen after Ubuntu boots up, just a 'mode not supported' message on the screen.How can I log into Ubuntu in text mode in order to fix the xorg.conf problem? I hope there is a "hot key" to stop Grub right before it starts loading Ubuntu and allows me to log in into Ubuntu in text mode.

Since the computer does not have xorg.conf, can I have the computer generate that file because I need to work on it and so I need to create it. That is why it would be useful to have a xorg.conf file still.

I've been trying to setup dual-screen in my system, but the control panel complains it can't find xorg.conf and so I can't save changes I make in the nvidia control panel. I was trying various methods of trying to get a dual screen working how I like it.Left = 17" 1280x1024 that sometimes works (needs hitting a few times)Right = 21" 1680x1050 main screenI wanted to have everything on the right one, my main workspace. And I wanted a seperate x workspace on the left hand one. (Mainly so that when the one on the left decides to not work, I can use the panel thing at bottom to move apps to the right one)
Now I know since 9.10 xorg.conf is non-existant and so determind on the fly or something.Is there a way to get X to write out the current working xorg.conf that's it's using? i.e. It's auto determind x,y,z and that's what right now this second is being used. I want to save this as a working xorg.conf so I can fine tune it etc.

I started using 10.04 today and it seems that the xorg.conf file disappeared. It's the first time that the default xorg driver works for my nvidia card, and I want to know what drive is this. How can I know what xorg driver the system is using? Is there a command for that?

After few days of Googling, downloading and testing, I've finaly managed to make a working Xorg.conf for my iMac G3 (Slot-loading, Summer 2001). As many of configs found on the Internet wasn't working for me, I'm posting mine, which is based on data from many configs (some from Ubuntu 8.04, were not working on this new release without adjustments).

I have a fresh install of Lucid on my PowerMac G4 Desktop (PowerMac3,6) / 867MHz. Right now I'm stuck with a resolution of 800x600. From what I have read, I know I need an xorg.conf file (install doesn't create one). I've looked around for a working one - and tried creating my own with no luck. I gather the following information is needed:
Code:
*-display
description: VGA compatible controller
product: NV17 [GeForce4 MX 420]
vendor: nVidia Corporation
physical id: 10
bus info: pci@0000:00:10.0

I'm trying to improve the functionality of my mouse in my installation of Ubuntu 10.10 desktp 64-bit running inside a VMware workstation VM running on a Windows 7 64-bit host. I stumbled upon some instructions suggesting changing a xorg.conf directive (specifically, change the mouse protocol from "imps/2" to "explorerps/2") which I'd like to try out. However there is no xorg.conf file in Ubuntu 10.10. I tried using Xorg -configure to generate the file and placing it in /etc/X11/xorg.conf, but it seems to make no effect. Using "xinput list" the mouse is still listed as imps/2 even after I changed the xorg.conf file and rebooted. It seems Ubuntu 10.10 ignores the xorg.conf file completely? If that's the case, is it possible to manually specify this setting that used to belong to xorg.conf at all?

My PC running 11.04 was showing a blank screen after every 10 mins while watching BBC iplayer (with all the screensaver and power saver settings switched to over 1 hour). The picture returned when I moved the mouse but it was still annoying.
So I googled for a solution and found this page [URL]. Based on this, I did the following in terminal:
"sudo gedit /etc/X11/xorg.conf"
Then when the text editor came up, I deleted 'EndSection' from the xorg.conf file, and added the following lines:
Section "ServerFlags"
Option "blank time" "0"
Option "standby time" "0"
Option "suspend time" "0"
Option "off time" "0"
EndSection
My problem: upon rebooting the computer, I just got a purple screen with the Ubuntu logo, it went no further. I tried booting with the livecd and removing the lines I added, but it wouldn't let me save the file. I also tried booting into recovery mode but I'm not very adept at the command line navigation stuff, so I don't know how to find or re-edit the file.

I have an apple tv1 running ubuntu hardy. Due to audio video requirements I do not want to upgrade. I am trying to get 1080p24 working my TV. I ran X in verbose mode to ensure that my TV supports 1080p24 and it does. For some reason the X is not able to see the 1920x1080 @ 24Hz mode. I got the required information to add the modeline to my xorg.conf.
My xorg.conf is as follows
Code:
Section "ServerLayout"
Identifier "Layout0"
Screen 0 "Screen0" 0 0
[CODE]....
When I check the Xorg log file I have the following warning
Code:
(WW) NVIDIA(0): No valid modes for "1920x1080_24"; removing. Is there any way I can append the valid modeline for 1920x1080 @ 24Hz to. I am avoiding using a modified EDID.

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?
