Ubuntu :: Xorg.conf And External Monitor - Resolution Seems To Be Slightly Off As The Outer Edges Of Screen Are Cut Off
Sep 24, 2010
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?

Since the display of my notebook doesn't work very well anymore, straight vertical blue line on the right side of the screen, I want to connect an external monitor. (ADI [it doesn't say the exact model] 21 inch; resolution 1600x1200 and 85 Hz refresh rate).
I'm using Ubuntu 9.10 with kernel 2.6.31.17 and xrandr does not recognize the monitor correctly (see code of xrandr output). Adding a new mode did not work and currently it displays a resolution of 1200x768 which is horrible. In this version of Ubuntu the xorg.conf is not used anymore and is thus empty. As I have read you could create an entry in a new xorg.conf for your hardware which would be used by Ubuntu, having priority over xrandr settings.
But I do not really know what the monitor section in xorg.conf would have to look like, as the original screen would have to be set to 1200x768 or be disabled all together. The screens would have to be mirrored. Would the setting also work, when the external monitor is not connected to the notebook, so the original screen would display everything correctly.
Here some information about the system which will hopefully be useful for you. Please post helpful links I have overlooked or ask for more information.
My onboard graphics intel chip is capable of a resolution of 1600x1200 as it works in Windows:
lscpi output for graphics chip:
Code:
loaded kernel modules (relevant lines, at least I hope) according to lsmod (the driver from Intel web page is totally outdated and I think this is not the problem, so I didn't consider compiling a new driver)

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'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

monitor is a Optiquest Q19wb. I normally have is set on 1280x1024, but fedora will only go to 800x600. It has detected the monitor correctly. Not sure if being connected to KVM will cause issues. The xorg.conf does not exist. Have installed system-config-display but have not run yet.

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 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.

I've been having some trouble configuring my Nvidea GT 430 with my LCD TV. When I specify the larger resolutions like 1920x1080, there is always one inch trimmed off around edge. First using Linux Mint 10 LXDE, I booted with the new graphics card in. Without loading any drivers, I was able to select 800x600 or 640x480 and those had an inch of black around the screen. I installed the proprietary Drivers and then the screen was cut off a bit on the edges and the text was so tiny i couldn't see anything.
I then tried Linux Mint 11 Gnome. The text was readable, but still couldn't get the screen to match the TV edges correctly. I think it is a problem with my TV as this happens in windows and Linux. My TV is older and doesn't allow me to resize the screen within its menus. However, in windows I am able to use the Nvidea tools to resize my resolution to a custom size. It turned about to be about 1800x1020. I only really like using windows unless I absolutely have to though.. Is there a way to manually resize the display area in the xorg.config file? or any other workaround?

I installed FC11 on my laptop T43 and the video card is ATI Mobility Radeon x300. Now I have a problem of screen resolution with external monitor:
When I do presentation, I have to mirror the two monitors and both set to 1024*768, which is not perfect.
I remember that when I use RHEL 5 desktop edition, The system can automatically detect the external monitor and set it by itself ----- The laptop uses 1400*1050 and the external monitors such as projector uses 1024*768. But I haven't found such feature on FC11.

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

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 Virtualbox running on Windows Vista, and Debian running inside Virtualbox. Everything's running great, for the most part. Everything looks correct.
But when I'm in full-screen mode, the top edge seems to act (to the mouse) like it's the bottom edge, and the left edge seems to act like the right edge. For example, if I click in the middle of the desktop and drag left, as if to select some icons, when I hit the very leftmost pixel of the screen, the selection (but not the mouse pointer) jumps to the far right edge of the screen).
For the left edge, it's not such a big deal, but not having the top edge is kind of annoying: it means I can't select things from the menu in my top panel by slamming the mouse against the top of the screen.

i have a Fedroa12 installed as a VM, and my problem is that i can't change the resolution higher than 800x600 .
i am trying to do that with an Xorg.conf file. here is what i did:
1. telinit 3
2. Xorg -configure (root user)
3. cp /root/xorg.conf.new /etc/X11/xorg.conf
4. inside xorg.conf i have added the following:
under the "screen" section i have added:
DefaultDepth 24 then under the "SubSection" of Depth 24, i have added:
Modes "1680x1050" "1028X768" "800x600"
but then whenever i am try to start the X, it fails with the following message: no screen found...
since i am doing it for studying only, how to configure properly the xorg.conf file ?

FC12-x86_64/KDE How can I lock in the 1024x768 resolution in xorg.conf ?
The Option PreferredMode is Ignored , checking in Xorg-0-log.
If I put in Modes "1024x768" it gets changed everytime I reboot.
I'm using the Nvidia driver. Can't use the nouveau driver, the mouse disappears when waking the computer up after about a half hour of sleep, then I have to restart computer to get mouse to reappear.

I need to find notes on how to achieve higher screen resolution via Xorg.conf and some other fixes since I just installed the NVIDIA driver... seems out of the box, my resolution is horrid, though theres an added NVIDIA Server and my dual monitors aren't configured to work. I used this tutorial to get the driver installed.

I 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 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?

My laptop screen isn't working but I don't want to abandon my laptop so I am trying to hook up a new monitor. I'm using my 1 HDMI port, and my BIOS doesn't recognize the monitor on boot up. Also, my xorg.conf file is not configured for this monitor. My question is what should my xorg.conf look like? I have a bit of a start on it(see attached) but it is not quite right. How do I set up the Toshiba as the default screen, in order to use this monitor when Linux starts? Other info: I use Debian 5.0 with Gnome.

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?

Just a day ago I did a clean install of 10.04, after wiping the disk clean of 9.10. So far everything's working great. Except for my old dual-screen configuration. A year or two ago I badly wanted to have 2 monitors, where both would share the same desktop/workspace allowing me to drag windows back and forth between the two. After a lot of research, I finally was able to put together (although a probably quite sloppy) xorg.conf file that did the trick for me.
My case is somewhat unique in that my left monitor is horizontal, while my right monitor is rotated 90 degrees, and is vertical. In 10.04, my old xorg.conf file sort of works, but I have problems on my right, vertical screen:
- when I move my cursor onto the vertical screen, when I try to move it above where my left, horizontal screen's boundaries end, my cursor jumps down to the bottom of my vertical screen. I can't access anything with my cursor above this boundary on my vertical screen. Note that my vertical screen's bottom is in aligned with my horizontal screen's bottom, and that the vertical screen sticks up above the horizontal screen, as both have a 1680 x 1050 resolution/widescreen aspect ratio.
- however, it appears that only my cursor is having issues accessing the upper part of my vertical screen. When I maximize windows in this screen, they properly fill it up entirely like they should. (but I still can't access the top parts of these applications with my cursor).
So obviously there must be some boundary managing where my cursor is allowed to go, and another set of rules defining the boundaries that the windows themselves can be shown/take up. Also note that because of my right monitor being rotated vertically, I'm forced to use Xinerama. Can someone help me go through my xorg.conf file, below, to help me get this "simple" cursor issue fixed? I'm sure it's just one minor thing that has to be changed, but I'm not sure what:
Code:
# nvidia-settings: X configuration file generated by nvidia-settings

I'm trying to play around with the orientation of my monitors (portrait vs landscape), and it's now obvious to me that they are best viewed from a high angle when placed on their stands normally. As I change their orientation, it would be nice if I could manipulate what angle they are best viewed at. I doubt this is adjustable, but I thought I would come on here an ask since there are a myriad of configurations that I don't understand.
