Apparently you can't get EDID information through a Displayport->DVI adapter. That means that a default install of Lucid (or Natty!) does not recognize the resolutions of any monitor connected with such an adapter.
I'd rather not create an entire multihead xorg.conf just to specify NoDDC. Is there any other way to pass that option to X?
I had problems with the system not reading the monitor EDID and have fixed the problem by adding an override file in xorg.conf.d and all of that seems to be working well (although the system has not failed to read the EDID since I implemented the override. go figure).
The thing that I am wondering about is something I see in the Xorg log file. At the end of the log file, after everything seems to be configured, there are six (6) identical blocks of information regarding the EDID and modeline settings. Is this normal or is X stuck in some kind of loop? Everything is working and I am not waiting an inordinate amount of time to log on, or after. Just curious. Here is the log file.

A few months ago my monitor broke and began using an old one that does not have EDID.Since then i havent been able to configure my computer with a stable video configuration.I`ve tried a thousand times to edit xorg.conf and i actually got it let me use resolutions higher then 800x600, but when i reboot my computer my usuall setting 1024x768 gets switched back to a lower one - its a pain... my icons get scrambled, the gnome panels, etc.Do I need to edit any other file then xorg.conf?
And another thing I noticed today is that the gnome display manager does not recognise the higher resolution of nvidia-settings. Does it have a seperate settings file?
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
[Code]....
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.
View 3 Replies View RelatedI'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 am running Wheezy 7.9, I have a Biostar motherboard with integrated Intel graphics (945 chip set), and a Viewsonic va912b 19" LCD monitor. I have recently been having problems with the computer not being able to read the EDID data from my monitor. About half the time the EDID is read okay. So, in order to set the monitor to the desired resolution I have created a shell script to set the resolution after I log in. Knowing that my monitor supports 1152x864 @75hz I used cvt to get the modeline info.
Code:
Select allroot@JohnBoy:/home/john# cvt 1152 864 75
# 1152x864 74.82 Hz (CVT 1.00M3) hsync: 67.71 kHz; pclk: 104.00 MHz
Modeline "1152x864_75.00" 104.00 1152 1224 1344 1536 864 867 871 905 -hsync +vsync
Then I wrote this shell script.
Code: Select all#! /bin/sh
#! /etc/init.d/monitor_1152x864x75
#
#add monitor resolution not being found at startup
#data from cvt
xrandr --newmode 1152x864_75.00 104.00 1152 1224 1344 1536 864 867 871 905 -hsync +vsync
xrandr --addmode VGA1 1152x864_75.00
exit 0
It works fine, but I see a difference between what cvt gives versus what I see in the xorg log file (when I get a good EDID read). Here is what I see in the xorg log.
Code: Select all[ 17.611] (II) intel(0): Modeline "1152x864"x75.0 108.00 1152 1216 1344 1600 864 865 868 900 +hsync +vsync (67.5 kHz e)
Notice that there are some small differences in the horizontal and vertical timings, cvt versus xorg log.
The biggest difference, to me, is that cvt has -hsync and the xorg log shows +hsync. I would assume that the data shown in the xorg log file is based on what was received from the EDID and therefore is what the monitor expects. Is that a correct assumption? And might using -hsync as per the cvt, versus +hsync, affect the monitor operation? Using -hsync does not appear to create any kind of video artifacts (tearing or distortions).
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 am trying to fine tune the S-video output settings for my xubuntu box running 9.10. I am having some trouble getting modes loaded via xorg.conf. Currently, my xorg.conf file looks like:

I am setting up a display system that will not have a keyboard/mouse and automatically boots into gnome and starts up firefox to a display page. The page is optimized to a 720p resolution which I can set when we use a TV for the display, but is not an option if we use a monitor. I am trying to find a way to set the resolution to 720p automatically on boot up. I am always using 16x9 displays with a DVI connection (to HDMI on TVs)
I was able to get one monitor working by creating a script and setting it to load in the Startup Applications as shown:
Code:
#!/bin/bash
scnres="1280 720 60"
modeline=$(cvt -v $scnres | grep Modeline)
modeline=${modeline#Modeline }

I'm trying to get my screen resolution set in Mythbuntu 9.10, but there is no xorg.conf on my system! I'm trying to figure out what to do (the xfce tool on mythbuntu doesn't offer the correct resolution, and I'm not even sure what driver I'm using). I've seen other threads saying to run nvidia-setup or somesuch. I assume the appropriate tool in my case would be aticonfig (I saw that elsewhere too) as I'm using an ATI Radeon 9600XT, but that tool says:
Code:
aticonfig: No supported adapters detected
I want to change color depth, but there's no xorg.conf file to edit... what to do? btw, shouldn't there be a simple gui for that? Like for changing resolution
View 5 Replies View RelatedI am trying to run using WINE. It has a platinum rating on the site, and runs perfectly on my laptop.on my desktop it doesn't seem to run at all.The screen goes black,then brings me back to the desktop. I manually ran the WINE command in the terminal, and it produced the error "err11settings:X11DRV_ChangeDisplaySettingsE x No matching mode found 320x200x8 @0! (XRandR)". The laptop and desktop are both running the same version of WINE (1.3.3) and have similar Nvidia cards (laptop has a mobile 9600, desktop has a 9800). I found a bug report on this exact issue on the WINE website (I'll paste a link), and they mention that the solution is simply to add the 320x200x8 resolution mode to Xorg.conf.
I've tried generating the line that I may need with a web-based modeline calculator, referenced on another thread, but it caused my system to fail booting. Luckily, I backed up xorg.conf before making changes and restored the old one via recovery mode. Here's the link to the calculator, I may just be using it wrong: [URL]
I have Natty Narwhal and everything was working. Then I moved it to my HDTV, and I had overscan issues. Following some advice I found online, I edited /etc/X11/xorg.conf with new information including a ModeLine.
Upon restart, I get my BIOS screen, the Ubuntu splash, then... nothing. The display goes to sleep. I can ping the computer, and everything seems to work except I have no video.
I did backup my xorg.conf file, but I don't know how to get to it without a display. Hindsight tells me I should have given myself a way to remotely control my computer before messing with xorg, but you live and learn.
I've read online that there is a way from the login screen to get to Terminal without loading the desktop environment, but I can't get to the login screen.
I've also tried using a Linux LiveCD to access my filesystem, and that works to view files, but I have no root privileges.
Is there...
...a way to get to Terminal without loading the login screen?
...a way to give myself root access to my harddrive from a LiveCD?
...something else to try?
I'm running Ubuntu 9.10 on an oldish IBM Thinkpad X32 (12.1in 1024x768 LCD, 16MB ATI Radeon). On the initial install of 9.10 I couldn't get any higher resolutions working, following the instructions in [URL]..
1024x768 resolution is running ok but some graphics are noticeably slow - a prime example is the "File Browser", switching from one app to this app, you see a grey window for a second, and then finally the File Manager displays.

Now, I need to write a custom xorg.conf file to force X to use the native resolutions of my chip.
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

I am running kde 4.4 in virtualbox , but cannot create xorg.conf to get a correct resolution. X -configure = segfault. Older releases were fine - lenny, even ubuntu hardy / lucid.
View 6 Replies View RelatedI am looking for a generic vesa driver xorg.conf file that will work with most any 1024x768 monitor.
This is for a network appliance and our field people have many different type of monitors.
This product will mostly be used "headless" but sometimes our field people will plug in a monitor.
The intel driver will not even start x without a monitor plugged in so I found it necessary to go to the vesa driver.

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 looked for a solution to this,and found a thread for it ,but I dont know how to do what it says.Here is part of it by the user "cameronol": There is a bug in Ubuntu 9.10 Karmic with the default /etc/X11/xorg.conf involving Nvidia. receive the error"Failed to parse existing X config file '/etc/X11/xorg.conf'.Then he posts:

Then he says to delete the first section with the default screen,and it will be fixed.But HOW do I look for the /etc/X11/xorg.conf file to edit it,and how do I edit it?I am new to ubuntu,but I have learned to use a terminal(I think)It seems to be just like the "run" box on Windows.I did a search for the file,but came up empty.I want to fix this cause every time I restart,I have a low resolution that is impossible to work in.
I have an 27" iMac which I wish to use as display for my Ubuntu machine using it's mini Displayport as perTo that end I bought a new Intel DH67GD motherboard and 2600k CPU and a Displayport->Mini Displayport cable.However it seems that X doesn't detect the displayport connection correctly. When I boot the Ubuntu machine the iMac correctly switches to that input and Intel motherboard screen appears on the display followed by the grub interface.However it seems that when X should start it doesn't recognise the Displayport connection. The iMac goes back to displaying it's own screen and the X logs don't seem to recognise the connection

I'm not sure what has happened. The last update I did was on the 15th. I've rebooted a number of times since then and haven't updated/installed any packages.

I occasionally use a DisplayPort->HDMI cable to connect my laptop to my AV-Receiver, however I only get the picture to the AV-Receiver, but no sound. I read that not all DisplayPort->HDMI cables support sound, so I tested Windows7 on the same machine and it transmitted sound over that cable just fine. So I conclude that it is a Linux driver problem.
So I generally wonder whether this can be made to work easily or not. Does anyone here have experiences with this topic, especially with nvidia graphics cards managing the display port? (I did find older posts about HDMI audio, but they were all concerned with ATI graphics.)
pavucontrol / phonon do list a "High Definition Audio Controller Digital Stereo (HDMI)"-device, but sending sound to it does not do a thing. Furthermore, my dell laptop only has a displayport, but no HDMI connector.
