General :: Xorg Configuration For External Monitor?
Oct 15, 2010
A few days ago I installed browserlinux onto my AspireOne netbook whilst connected to a 15" external monitor of 1024x768 at 60Hz. During installation I ran the Puppy Xorg Wizard with the netbook's monitor (1024x600) switched off. It selected the optimum resolution of my external monitor correctly as 1024x768 and the 'intel' driver for the Intel 945 Express chipset. However when I ran programs and maximised their windows they would cut off about a third from the bottom. I ran the Xorg Resolution Wizard which showed a resolution of 1024x600 despite xorg.conf only showing an option of 1024x768. I tried to copy a xorg.conf from Linpus (Fedora 8) which had required some altering in the past to run the external monitor at the correct resolution but X failed to start (possibly because Xorg in browserlinux is a newer release). Would it be possible for someone to upload a xorg.conf file which would enable display the external monitor at the correct resolution (and ideally allow switching between the two monitors - under Linpus the hotkey is Fn + 4) or suggest alterations to the current file?

I have an Asus z9100 laptop with an Intel 855GM integrated graphics chip, which is running Karmic (the purpose of the laptop is to be a MythTV frontend so my understanding is that it needs to run 9.x in order to connect to the MythTV 0.22 backend - I have installed and configured this using the installable Mythbuntu package) and the laptop is subject to this bug which causes random freezes:
[URL]
So, following advice for similar freezes I've seen, I have added the following options to my grub menu.lst on the kernel line:
nolapic nomodeset
and I have edited xorg.conf so that it makes use of the vesa driver instead of the Intel driver. This results in no freezes and if I wanted to watch Myth on the laptop screen I'd be squared away. However, the laptop has a damaged screen so the point was always to output the signal to an external monitor via its VGA out.
When I attach the external monitor and boot with the setup as described, the external monitor is never detected. But I noticed that if I remove the "nolapic nomodeset" from the kernel boot line, it is detected. However, signal is only output to it during the earliest part of boot (when the Ubuntu logo is in the center of the screen before the full-screen graphic with the animated progress line), after which the external monitor goes black and all the display output goes to the laptop screen. The external monitor power button is still lit up green as if it has been detected and is receiving signal, but it's just a black screen.
get the signal out to the external monitor after the initial part of the boot process, using the vesa driver? Here is the current state of my xorg.conf:
Code:
Section "Device"
Identifier "Configured Video Device"
Driver "vesa"
EndSection

I have a netbook (Acer Aspire One) I'm running Slackware 13. and usually, I prefer to connect an external monitor. When I switch my machine on with the monitor connected, the display is duplicated on both screens and since I just want the netbook's screen to be off and only see the display on the external monitor, I can doxrandr --output LVDS --off
Great! However, it's a hassle to do this every time I log in and I'd like to automate the process if possible. I did some googling and I found that if you want to automate xrandr commands, you can put a script in /etc/X11/Xsession.d/ (see this). I wrote the following script to automate my xrandr commands and since the Xsession.d directory didn't exist, I tried creating it. The script was called 45custom-xrandr_settings, as the one on the RandR wiki is called the same.
Code:
#!/bin/bash
# Check whether the external monitor is connected

I have Ubuntu (running Jolicloud) on my HP dv2000 laptop, connected to my Sony AV Receiver through HDMI to use the TV as an external monitor. However, the resolution seems to be slightly off as the outer edges of the screen are cut off. Is there a way to fix this by editing the xorg.conf file? My current setup is below. I tried adding the line "Virtual 1244 700" to the subsection "display", but when I restarted it threw me into low graphics mode. Is there anything else I can try?
I also tried setting up the resolution at 1920x1080 on the TV and kept the default resolution on the monitor as 1280x800, and as you would expect displays the entire desktop in a smaller version on part of the tv. However, the desktop is still offset, leaving the top and left margins cut off. So, perhaps I need a way to offset the screen? Is this possible in xorg.conf?

I have been tasked to set up 2 monitors on SUSE Linux Enterprise that are a clone of each other, but each displaying different resolutions. The primary display has a max resolution of 1024x768 while the secondary display has a max resolution of 800x600.
The problem comes when the secondary display shows a "cropped" version of the desktop. Is there anyway to show different resolutions on each display while maintaining the proper desktop look?

I am not sure if this is the correct forum to post this topic (I was struggling between hardware and software). But since I do not think this was a problem with my hardware(monitor), I decided to post it here.

My laptop has a dual boot Debian + Ubuntu installation.
In particular I am using Debian 8.0 with stock kernel 3.16.0-4 (or equally 4.1.10 custom compiled, I tested it and it does not make any difference for the subject of this post).
Ubuntu is 14.10, with stock kernel 3.19.0-15.
In both installations I have nvidia nouveau drivers and intel integrated graphics drivers installed and loaded. This is the default for both installations.
In both installations I have xorg automatically configured (no xorg.conf file present in /etc/X11). In both systems the content of /usr/share/X11/xorg.conf.d is the same for what moitors are concerned (differences in mice and trackpad entries).
Unfortunately, the video configuration in Ubuntu 14.10 works out of the box. In particular I can plug in an external monitor/projector and it will fire-up the nvidia card (nouveau drivers) to power that monitor.
Debian 8.0 on the other hand does not even detect the external monitor.
I don't know where to start to solve the problems.
The hardware is as follows: the laptop (lenovo W530) features both an Intel integrated graphics card and an Nvidia K1000M. The VGA port is connected only to the Nvidia card (this is according to my online research, as I don't know how to check this).

I'm using dual-screen output with KDE 4.4 on my laptop. Is it possible to have the KDE panel on the external monitor if attached and back on the laptop's LCD panel as soon as the monitor is disconnected?
It seems that Plasma prefers the built-in LCD even if an external monitor is connected. I tried various settings with xrandr and also in the System Settings but none of them helped. The only way to move the KDE panel to the external screen is to disable the built-in LCD.
What I would basically like to do is to use the external monitor as primary in the office and the laptop LCD next to it as a second screen. When I'm traveling I'd like to use only the laptop LCD.
Is there also a nice way to switch between the screens? On the Internet I found a script for the "screen switch" key for IBM Thinkpad and modified it to work on my Dell. But it would be nice to have this also automatic: autodetect the monitor attachment/removal and perform a configured action. The KRandr doesn't seem to have such a feature. Is there anything I could use?
My system is: Kubuntu 9.10 with KDE 4.4 upgrade. Hardware: Dell Inspiron 1545 with Intel GM45 card.

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 installed Karmic on an older PC I had laying around, and the only trouble I am having is with screen resolution. It uses an old ATI chipset (onboard) for video, and it doesn't seem to do EDID correctly, so I can't display anything higher than 800x600. I have tried creating an xorg.conf, but it's still not working. How can I tell Xorg to ignore the fact it can't detect a widescreen monitor and display something larger than 800x600? I noticed the log says the sync's are out of range, but I am not sure how to fix it.
Here is my current xorg.conf.
Code:
Section "ServerLayout"
Identifier "X.org Configured"
Screen 0 "Screen0" 0 0
InputDevice "Mouse0" "CorePointer"
InputDevice "Keyboard0" "CoreKeyboard"
EndSection

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]
The lcd does not have any controls to tweak.

I am having problems getting my external monitor to work. When I plug in the monitor, both the laptop screen and the external monitor go black. When I unplug the monitor, the laptop screen works again.
When I startup with the external monitor plugged in, neither screen works or teh computer hangs or something.
I have had the external monitor going on a couple of occasions. I did manage to configure my monitors through System Settings > Display. I turned off the laptop monitor as I just want to use the external. But after rebooting, things didn't work.
I have a Thinkpad E420, Fedora 15

I have an external monitor connected to my laptop (extended display). I always drag the Totem player from the laptop screen to external monitor to watch video files. I wonder, if the Totem player can be set to open in the external monitor automatically, everytime I open it?

My software and hardware information are as follows. I have Fedora 12 and KDE 4.4.5 installed on a Dell Vostro 1500 laptop. I believe it's a 64 bit processor; it's an Intel Core 2 Duo CPU. The external monitor is a Dell as well.
My problem is that my system does not seem to be detecting an external monitor that I have connected. Everything else is working just fine; however, I would like to have the option of attaching an external monitor. When I plug the external monitor into the laptop, the external monitor remains black and appears to be in power save mode. The results of xrandr -q (with or without the external monitor attached: it doesn't appear to change) are as follows.
Code:
How can I get my laptop to recognize that the external monitor is even connected? Let me know if I can be more specific or provide additional details.

I recently installed Debian, using the amd64 Network Install .iso. I'm using XFCE4 as my desktop environment, and everything is working well... on my laptop's screen.
My desired setup is to have my laptop sitting on a well-ventilated shelf, closed, and to have an external monitor be my main monitor. I want this because I'm using my laptop as my "home" computer, so it never moves, and I don't like the keyboard/trackpad. My laptop has a VGA output, and I can get my desired setup on my Windows partition (not stating a preference ; just that the hardware CAN do what I want it to).
I've been working my way around the Internet for a few days, now, and I've got the commercial NVIDIA driver installed. If I run sudo nvidia-config --twinview I can get my external monitor to be part of the display, which is great, but it's part of a dual-screen monitor setup, which is not what I want at all, because (a) XFCE's multiple virtual desktops are good enough for me and (b) my graphics card is integrated, and I'm trying to squeeze every drop of performance out of my laptop that I can (1 gig of RAM; the less that my graphics card eats into it, the better). Plus, it'd be annoying to accidentally drop something on my laptop's screen, and then have to dig it out of the shelf in order to undo it. I'm not saying that I'm consistently clumsy, but I'd eventually end up doing it.

I've got an eeePC with a really tiny monitor, so whenever I go (home, faculty, parent's home, friend's home, ...) I attach it to any external monitor I can find.
If it matters my system is like this:
Archlinux
Linux 2.6.36
Xorg 7.6
X server 1.9.2
Intel Corporation Mobile 945GME Express Integrated Graphics Controller (fully accelerated by intel modules)
When I boot up the system, it uses the integrated monitor (LVDS1) only, and I have to manually manually switch to the external monitor (VGA1) using xrandr.
Is it possible to configure my Xorg (or whatever) so that it uses the VGA1 output if present?

I have a Lenovo 3000 N100 laptop which LCD does not work anymore.So I borrowed a monitor from my friend and started using it(it has been few days).I had installed Fedora-12 few months ago. After connecting the external monitor, I found that this one shows good graphical start-up but just upto the login screen(just before the login screen, login-screen does not come) and it proceeds no more.Though I can get the virtual consoles restarting xserver is of no use.

I'm using Xorg 7.5 on a Radeon HD4870 with the FOSS radeonhd server on my HP 6830s. The laptop has a VGA connector and I attach it to a 37" panasonic plasma TV. It works fine except for a little annoyance: when activated, the TV screen is set to the resolution of 1360x768 (which it reports as being the highest it supports) but all the image is shifted by about 100 pixels to the right. I can't see the leftmost part of the page, and I have a black vertical bar to the right.
If I change the resolution to 1024x768 there is no shifting, the image fills the entire screen with no parts hidden, but at this resolution the image is stretched. How can I tune the position on the external monitor so that the image is centered in the screen filling it entirely?

How can I detect when an external monitor is connected in linux? I need to run various scripts to set up my workspace. Is there some clever way to kick off a script when the monitor state has changed? I'm using the Nvidia display driver.

I have an Acer Aspire One AO150 and am having trouble plugging in an external monitor under Ubuntu 9.10. There were no problems under 9.04. If I plug in an external monitor once the machine is already up, then bring up the 'display' application to activate it, it basically hangs. There are no problem under these circumstances if I have desktop effects turned off.
A few more details after a question below. The machine does not respond to its keyboard commands to switch to an external monitor, nor does it respond to Ctrl-Alt-F1, etc to switch out of X. The pointer is visible on the monitors (at the edge of each) and is frozen as a 'busy' cursor, but with no animation. The kernel does respond to SysReq commands (REISUB).
In the latest attempt I had the external monitor active earlier, then removed it and activated desktop effects. Upon plugging in the eternal monitor then bringing up the display application, it hangs.

I connected an external 22" monitor to my new linux netbook and now I am trying to improve the display clarity. By shifting the "clock" monitor bar to 100 ,the letters were less faded but edges of my screen were lost (by zooming in). Can I fix that through Linux?

I have an HP Pavilion dv9000 which I would like to use completely with any Linux OS. I have tried to install Linux Ubuntu 10.04.1 but it appears that it doesn't recognize the external monitor and ends the installation. I have a clean hard drive that I could install but I do not know which of the two drives I should replace. I can only get into windows in safe mode and I would think this may have something to do with the problem, don't no.

I bought a very beaultiful pink tv-monitor 26", model LG26LED6500 for my daughter and I also intend to enjoy it setting up in my slackware 13.37. Then I use a VGA cable and 6600GT nvidia card, but now I'm having a doubt because there aren't vertical and horizontal frequencies specs in this manual. Only:
I did a xorg.conf using a vesa driver and kde screen output was a 1024x768 - 61hz.
If I try to use a nvidia driver and xorg.conf piece above X break down. If I use any manual frequency parameters X break down too.
1)What's the difference between CRT config and tv-monitor xorg?
2)Have I use strings modeline monitor and modes screen in this situation?

One monitor is working fine but the display is not coming on other monitor. I guess no problem in monitor because I swapped the cable to check the individual monitor. When I try to install the new driver its giving GCC-VERSION-CHECK while installing. And I do not think I have to install the new driver because it has already one. What should I do to configure the dual monitor. Do I have to edit any configuration file.
My system configuration details are below.
Redhat version : Redhat Enterprise Linux WS release 3 (Taroon update 4)
Driver in SRBC 26: NVIDIA-LINUX-x86_64-1.0-7664-pkg2.run
Nvidia card model : Quadro fx p171

I've been trying to get it to work on my laptop off and on for several years now, experimenting first with Redhat (version 6.1, I think) and now trying with Ubuntu 9.04. I've done a full install using the entire hard drive (no dual boot). So I'm trying it for real this time. I'm having a problem with my video drivers. The video is ok (not great) and I don't seem to have any options to adjust it.
When I go into system > preferences > display, I see monitor "unknown", set at 1024x768 with a 75 Hz refresh. If I click on "detect monitors" nothing happens. It says under system > administration > hardware drivers that "no proprietary drivers are in use on this system". I've got two options:
[code]...
For the first part of boot, I have access, but then when it comes up into Ubuntu, the big monitor (a Dell 2500, I think, plugged into the stock Toshiba docking station via DVI) quits working, and all I have is a dim picture (dark, like something's sapping power from it) on the laptop display.....

I just installed the new Ubuntu onto my laptop and want to use a second monitor with it in twinview.
I have to use the Nvidia X Server Settings and while I can get the second monitor working, I cant get any resolutions higher than 1024x768. But I know for a fact that I can get better resolutions as I used to use that monitor as my primary. I had to manually change my xorg.conf tho.
How do I change my xorg for the secondary monitor? if I add a new monitor and screen sections it breaks X and it sends me to teminal on boot.
heres what I tried The stuff I added is in bold:
Code:
# nvidia-settings: X configuration file generated by nvidia-settings
# nvidia-settings: version 260.19.06 (buildd@yellow) Mon Oct 4 15:59:51 UTC 2010
Section "ServerLayout"
