Sometimes dual head display is stretched

Sometimes when I am logging in, instead of the gdm login screen appearing on my default monitor, it turns off the default one, and half of it appears, stretched in the secondary one. If I log in with this setting, then the primary monitor is off unless I set it back with nvidia-settings. Normally, and most of the time, however, it is fine. This never happened on ubuntu so I think its becuase i did something wrong. I'll provide any config files you think may pertain, just ask. thanks

This is a bug, when operating in dual display mode on Win 2k with the desktop setup as a side by side virtual monitor ALL Java GUI applications fail to start. I've noticed this on all version of the JVM. However, when the desktop is setup as a top/bottom virtual display, Java GUI apps work correctly.

[SOLVED] Configure dual head with different resolutions xf86-video-ati

I have 1680x1050 and 1280x1024 monitors which I would like to setup so that I have two displays (:0.0 and :0.1), i.e. can't drag a window to the other display, but can move the mouse from one screen to the next. The graphics card is Radeon HD 4850.
At the moment I have one screen only, so I can't move the mouse from the first to the second screen, it is captive in the first screen.

It doesn't look as if xrandr can help as it reports a maximum virtual desktop of 1680x1680.
Because the two monitors are different resolutions I don't know if a single screen is the answer.
I used to have two displays/screens configured to two different resolutions matching the monitors using the catalyst driver but can't get it working using the xf86-video-ati driver.
Any help would be appreciated.
Thanks

Would still be interested to get a seperate display for each monitor working though.

Xorg.conf , nvidia 96xx and dual head failure

i cant get Xorg to work with nvidia driver at all.
here is where i am.
setup aurch linux [X]
setup xserver with NV driver 1 head[X]
setup dual head[]
ok so i cant even get nvidia drivers to work or dual head on the NV driver.
i dont have an xorg.conf setup but i have tried the xorg.conf from my fedora setup but it just black screened.
here is my error log.

Ive tried everything i could think of or what arch wiki could. I came to aurch linux to learn more about linux (fedora holds your hand to much.) but i dont think i can figure this one out on my own.

serverman,
let me see if I understand your situation.
You are using the nvidia drivers and want to setup a dual screen with independent screens (?).
Without a xorg.conf one screen should work out of the box with one screen.
For the proprietary drivers you will need a minimal xorg.conf:
Section "Device"
Identifier "Configured Video Device"
Driver "nvidia"
EndSection
Section "Screen"
Identifier "Default Screen"
Device "Configured Video Device"
DefaultDepth 24
EndSection
This still has only one screen, but can you try it and tell what happens ?

Dual head setup (mach64 - ATI Rage Mobility)

hello everyone!
I want to use a new extra monitor I got recently, with my laptop, I use aweosme.
I have installed:
xf86-video-mach64 (recompiled with dri support)
mach64-dri (from community)
mach64drm (from AUR)
https://wiki.archlinux.org/index.php/Mach64
Still I can't get OpenGL to work:
ismaelvc@toybox ~ $ glxinfo | egrep "direct rendering|OpenGL renderer"
direct rendering: Yes
OpenGL renderer string: Gallium 0.4 on softpipe
I don't really know if it got something to do with this but I post it anyway in case it is.
xrandr doesnt detect the other monitor:

320x200 85.0

Still it displays exactly the same that gets displayed at my laptop.
I used to had problems with the drivers, I needed both mach64 and radeon for it to detect the screen properly, until I created a "20-mach64.conf" with this:
Section "Device"
Identifier "Card0"
Driver "mach64"
Card "ATI Rage Mobility - Mach64"
Option "DMAMode" "async"
Option "ForcePCIMode" "false"
Option "AgpMode" "2"
Option "AgpSize" "32"
Option "BufferSize" "2"
Option "LocalTextures" "true"
Option "EnablePageFlip" "true"
EndSection
Section "Module"
#<Your modules>
Load "glx"
Load "dri"
EndSection
Section "DRI"
Group "video" #change to any desired group to restrict access
Mode 0660
EndSection
I have a doubt regarding the commented line that came as example in the mach64 wiki that reads <your modules>, I don't know what goes in there.
Also I red this for some mach64 related xorg info:
http://www.x.org/archive/X11R6.8.0/doc/ati5.html
http://forums.fedoraforum.org/showthread.php?t=201482
The last one is for a cursor problem I have, but it wont get fixed, neither, anyway the default xcursor looks good in awesome, I switched to cli apps form many tasks, and use uzbl now! all this plus arch is now so minimmal I love it lol!
I red in a post (not in this one) mach64 chips supported dual head, but I can't find it again, I will post it when I find it.
Thanks in advance!
EDIT: ok here it is, where it say its supported: I don't understand all the configs.

Sorry to necrobump but I was seeing you get a lot of incorrect information on LinuxQuestions.
The mach64 driver does NOT support dualhead. Some chips are capable of it but this feature has yet to be added to the driver. It is also not compatible with xrandr. The man page you linked to mentioning dualhead support is for xf86-video-ati. It is only accessible from the git history of xf86-video-mach64 because those drivers used to live in the same source tree.
I can try to help with DRI if that's still not working for you.

Xrandr not listing dual head outputs

I'm running into a little annoying problem with xrandr. It doesn't want to list my nvidia 8800gt's dual heads as different outputs.

So it only lists "default" even though I have a second monitor plugged in over DVI (a TV actually). I know it's not a problem with output to the TV because if I specifically set up output in xorg.conf it works fine. However I would much prefer to enable and disable output to TV on an as-needed basis.

Your dead right, it did work but now for some odd reason the virtual screen size is no longer large enough to accom' both screen.

I installed xf86-video-ati and assume it is loading fine.

I would love to but I do not have such a thing, I can post my Xorg.0.log if you would like to take a look. I believe I am trusting HAL to auto configure each time so xorg.conf doesn't exist. All seems like black magic to me but to date has worked well.
Will I need to create an xorg.conf file, populate it and get it working to be able to use both screens as well as to be able to play video on VGA-0?
I can duplicate LVDS onto VGA-0 but again video will not play on VGA-0.
Thank you both so far with you help. Would love to sort this out and if I need to get dirty with and xorg.conf file then so be it.

Setting up independant dual-head configuration in the usual way?

I'm preparing to set up a dual monitor system pretty soon using an ATI Radeon card. I went through the wiki and read what the ATI page has to say:
Independent dual-headed setups can be configured the usual way
The problem is that it gives no indication of what the usual way is. I vaguely have an idea that I might need xinerama, but couldn't find a wiki page on that either... I've also tried googling with limited results.
Is anyone able to let me know of a good resource for this?

Check this out: https://wiki.archlinux.org/index.php/Xorg
I'm using a radeon 6870 with kde and in my case I was able to set up my dual screens using Settings > System Settings > Hardware > Display and Monitor > Size & Orientation, clicking Save as Default once I had things set up the way I wanted made the settings permanent
If you're going to use Ati's catalyst control center driver then you should probably also read this page: https://wiki.archlinux.org/index.php/ATI_Catalyst

Dual-head on NVIDIA

Hello, I'm trying to configure a dual-head setup (NVIDIA proprietary drivers). I've tried both Xinerama and Twinview, but the screen is always treated as one big virtual screen and window managers spread fullscreen windows over both monitors.
Here's what I've tried (they all resulted in the above):
- # nvidia-xconfig
- These instructions
- # nvidia-xsettings
- These instructions (I might've misunderstood them, they were fairly vague)
In addition, Xinerama seems to disable the randr extension, which makes me unable to use xrandr or arandr, so the preferred option is to use Twinview.
For clearance, when I open arandr, I see one big, wide screen called default. How do I set it up so that it shows 2 different screens?

Separate X sessions on dual screens (both monitors have own x sessions )
no xrandr
only

Dual 17" Displays

I presently have a Dual G4 with two 17" Apple Monitors connected and running side by side. I'm looking to purchase a Mac Mini and was wondering if there was any way to continue to use both of these monitors with that machine?

The Matrox Dual head 2 Go device (http://www.matrox.com/graphics/en/gxm/products/dh2go/home.php) will allow you to run dual displays from your mini, and use them in extended mode, not just for mirroring - however it uses analog input (thus can be used with the mini and it's supplied DVI/VGA adapter) but only outputs VGA.
There has been a recent discussion of the use of a specific splitter cable that will allow the existing DVI-I output on the mini to be split between one DVI and one VGA display, but there has not yet been a clear outcome regarding it working in MacOS. See http://discussions.apple.com/thread.jspa?threadID=832771&tstart=0 for the discussion.

Solaris 10 x86 w/ Matrox G450 dual head and xinerama

I have solaris 10 x86 with matrox g450 dual head and x.org x-server. The problem is to get xinerama work. When xinerama isn't enabled, two different desktops work well - or, they work, but they are pretty useless because I can't move windows between them. So, I have to enable xinerama, but it seems, that neither JDS/Gnome nor CDE haven't been built including support for xinerama.
When I enable xinerama, X.org-x-server starts fine and there's dtlogin. When I login and it passes execution to gnome, it fails and x-server restarts. Same with CDE. But if I put 'exec /opt/sfw/bin/xterm to my .dtprofile', it starts ok and I can do some testing..
% dtwm
X Error of failed request: BadWindow (invalid Window parameter)
Major opcode of failed request: 149 (XINERAMA)
Minor opcode of failed request: 2 (XINERAMAGetScreenCount)
Resource id in failed request: 0x0
Serial number of failed request: 18

% gtk-demo
The program 'gtk-demo' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadWindow (invalid Window parameter)'.
(Details: serial 13 error_code 3 request_code 149 minor_code 2)
(Note to programmers: normally, X errors are reported asynchronously;
that is, you will receive the error a while after causing it.
To debug your program, run it with the --sync command line<br />
option to change this behavior. You can then get a meaningful
backtrace from your debugger if you break on the gdk_x_error() function.)
% gtk-demo --sync<br />
The program 'gtk-demo' received an X Window System error.

If I start /opt/sfw/bin/fvwm2, it works fine too, so the problem seems to be gtk/glib/gnome and CDE. One odd thing is that, normal CDE-programs, like dtterm, dtcm, dtcalc etc. works fine. But dtwm doesn't work in xinerama mode.
So, would anyone have any suggestion what could I do? Do I have to recompile my own GNOME, or could Sun do something to the next Solaris 10 update? (As far as I understood, current Solaris 10 release doesn't include zfs yet, so there will be update soon, I think)

Hello,
I'm also using a g450.
Now I'm trying for 5 days to get it work with xinerama under Xorg and/or
Xsun.
Can anybody tell me how to get it work ?
I would like to see a working xorg.conf.
(I don't know how to configure 2 screens for Xsun. Mybe someone can give my his configuration file(s) ?)
Thanks to all who will help me !!!
p.s. here is my latest attempt of xorg.conf which does not provide xinerama for me:

Kdemod 4.2 with dual head

I want to use dual head setting in kde 4.2 but it has bunch of issues. When in kde4 i issue the command
xrandr --output VGA --left-of LVDS
, it enable the dual head setup but the resolution defaults to 1024x768 for both my monitor and Laptop. When I change the resolution to the correct ones from the kde4 display setting in control panel, it screws up the dual head setup and the screens starts overlapping.
Has anyone managed to set dual head on kde4.

Two weeks late, but anyway...
You can set the position for the second monitor too.
xrandr --output DVI-0 --pos 1680x0
This works for my setup. The systemsettings xrandr module doesn't, how am I supposed to use that?

Nouveau graphical tearing, dual-head setup

I currently experience tearing while using the Nouveau drivers for my NVidia card. I experienced the same (or a similar) tearing issue while using the proprietary drivers, which, along with the inherent incompatibility with most of the linux graphics stack, led me to switch to Nouveau.
I'm using the 3D support from nouveau-dri along with xf86-video-nouveau and the most recent Gnome 3 build in the official repositories.
I have a dual-head setup with one 1024x768 IBM monitor to the left of a 1920x1080 Dell monitor. Both report 60Hz vertical refresh rate in their configuration menus.
So far, my attempts to solve this problem have consisted of the following steps:
1. Use a minimal xorg.conf and configure everything using the integrated Gnome display settings utility. The minimal xorg.conf was as follows:
Section "Device"
Identifier "nvidia"
Driver "nouveau"
Option "GLXVBlank" "true"
EndSection
2. Enable/disable the GLXVBlank flag in xorg.conf.
I do not experience the same issue when booted to Windows 7, using the most recent official NVidia drivers.
I would greatly appreciate any help anyone could offer on this issue, it is quite frustrating to boot into Windows to watch videos without horizontal breaks in every frame. Thanks!
Output from xrandr --current is as follows:

Hello. I have the same problem. Not just on Arch. I've had this problem with many distros, graphics cards, and drivers across the board. Installing the proprietary nvidia driver fixes the video tearing (vsync) issue for me. However; A) it's Linux, I don't want to use proprietary anything (otherwise I'd be on a Mac); and B) the proprietary driver will not flip my display to portrait anyway.
I basically have the same setup as Meyermagic. One GeForce 8600 GT, Two monitors (identical acers) 1680x1050 (oriented in portrait so 1050x1680 if you like), using open source Nouveau driver, created a minimal xorg file in /etc/X11/xorg.conf.d/20-nouveau.conf
Section "Module"
Load "glx"
EndSection
Section "Device"
Identifier "Nvidia card"
Driver "nouveau"
Option "GLXVBlank" "true"
EndSection
Both monitors have a refresh rate of 60Hz. I still get really bad tearing as I drag windows across the screens.
Again, I've had this issue with almost every Linux box I've built (the only time this is not even remotely an issue is on my Thinkpad T400 using the Intel graphics). I'm guessing I'm doing something wrong or I've just had bad luck because it is nearly impossible to find any support for this on any forum anywhere. Anything I do find is either a thread like this where someone asked the question and simply never got a response. Or it is some out-of-date forum that give you 10 ways to modify the xorg.conf none of which make any sense or don't work. Not to mention that xorg.conf is now depreciated anyways.
Seriously, even if there is a wiki that concisely explains in excruciating detail how to actually modify the xorg conf files then I could figure it out for myself but I can't find that anywhere which makes me feel really stupid because I know it has to be out there. If there isn't an xorg wiki or xorg.com site or something that explains how to use the thing then I'm not sure I want to live on this planet anymore.
If anyone can help in any way please do.

OpenOffice crash with dual-head presentation in Impress

Hi, I have an issue with Impress, I hoped that version 3.2 would fix it but it's not so. Now I think it is a problem of my system.
I have a dual head setup with an ATI card (Catalyst 10.5, xorg-server 1.7.6); I start a slide show with Impress on the secondary display, then when I press esc to return to Impress the program crashes. Starting it from the console I get this error messages:
$ SAL_SYNCHRONIZE=1 soffice -impress
** (soffice:3129): WARNING **: Inhibit method failed
** (soffice:3129): WARNING **: Inhibit problem : The name org.gnome.ScreenSaver was not provided by any .service files
** (soffice:3129): WARNING **: UnInhibit method failed
** (soffice:3129): WARNING **: Inhibit problem : The name org.gnome.ScreenSaver was not provided by any .service files
X-Error: RenderBadPicture (invalid Picture parameter)
Major opcode: 155
Minor opcode: 7
Resource ID: 0x1800911
Serial No: 40909 (40909)
I think the warnings are harmless, and that X-Error is the problem. I don't know if I should file a bug upstream, I searched OO bug tracker but I didn't find anything.
Thank you.

Hey, I just discovered the same problem here... I believe it's exclusive with oo, and go-oo doesn't have it.
EDIT:
According to this, it has to do with gtk, a possibly workaround (at least for me) is running this first:
export OOO_FORCE_DESKTOP="soffice"
Then openoffice doesn't crash when you close the presentation :). Hope it helps until we find a real solution :).
PS.- The warning still appears though.

Dual-Head Disconnected DVI-0

Hi,
I am trying to get dual head working with no luck. The two monitors work fine when linux is booting (cloned view) but under Xorg I can't get the second one working.
I am using Xorg 1.6 X.Org X Server 1.6.1 and [testing]
My card is a 01:00.0 VGA compatible controller: ATI Technologies Inc RV370 5B60 [Radeon X300 (PCIE)]
I am using a DVI-to-VGA extension cable for the DVI output and a regular vga cable on the vga one.
xrandr shows:
Screen 0: minimum 320 x 200, current 1280 x 1024, maximum 1280 x 1280
VGA-0 connected 1280x1024+0+0 (normal left inverted right x axis y axis) 380mm x 300mm
1280x1024 60.0*+ 75.0 60.0*
1152x864 75.0
1024x768 75.0 70.1 60.0
832x624 74.6
800x600 72.2 75.0 60.3
640x480 75.0 72.8 59.9
720x400 70.1
DVI-0 disconnected (normal left inverted right x axis y axis)
S-video disconnected (normal left inverted right x axis y axis)
So it sees the DVI-0 one disconnected.
I tried it with extra/xf86-video-ati and also with aur/xf86-video-ati-git.
Same results with both.
Like I said, both monitors work fine when Arch is booting up.
Any ideas?
Thanks in advance!

Both screens are exactly the same monitor so I'm not sure why I'm getting that. Any ideas?
You miss the 'Virtual' line in xorg.conf! Like this:
SubSection "Display"
Viewport 0 0
Depth 24
Virtual 2560 1024 <----
EndSubSection
Add it for for every bit depth you use.

Dual Head - Window managers / Desktop enviroments Issues

Hi.
Grasping how Xorg, KDM/GDM, and the many DE:s / WM:s handle Dual head and the likes is not a walk in the park. This is really not really helpful towards newbies, setting up tv-out and such...
Xinerama - cons:
No DRI / openGL
Not all apps are xinerama aware, and not many have option to be started up on xinerama screen.
Xinerama - pros:
Drag apps between screens
Xinerama - usability:
KDE: good
Gnome: poor (apps end up on second screen, second monitor is not very configurable)
Xfce: good
TvinView - cons:
Missing features (A good example is crt is primary monitor, ALWAYS. Not fun when using laptops in tvinview configs)
TvinView - pros:
Accelerated output.
Good configurability in xorg.conf (makes your brain hurt though)
TvinView - usability:
Cant say, not been experimenting much. should be the same as dual screens.
Dual Screens - cons:
Cant move apps between screens.
You get a barebone "extra" desktop on second screen, for "free", yay!
Dual Screen - pros:
Accelerated output
Start apps with enviroment variable "DISPLAY=0.1" to second screen
Duals Screen - usability:
KDE: good
Gnome: poor (Apps end up on wrong screen all to often, Autostarted apps in the notification area / system tray crashes)
Xfce: good
Needless to say i think all setups pretty much suck, but what to do, what to do...
Either way i run dual screens because i want glx accelerated graphics.
As i use xfce and kde, i have no problems with this setup, but what about all gnome people?
Also, i've been browsing the net for DAYS (really) trying to figure out how to stop xfce, gnome and kde from loading that second desktop. There is NO info whatsoever on how to do this.
I want plain X, on my second screen/head. I have heard of people having this, but because of gnome/whatever not supporting dual-head, back in the days. Also one guy i spoke with accidently got this behaviour with KDE 3.5.2 when changing from gdm to kdm.
I also WANT this bug (which for me would be a feature!).
This way i could fire up another WM on that head, or why not freevo as a dedicated media player together with my remote control?
help me out...

@pelle: I have the same problem with gnome... in my xinitrc I first start ratpoison on the second screend but if I start gnome afterwards it takes both screens anyway. It currently only works with two 'simple' WMs. Though, I like Fluxbox as a replacement for gnome/kde very much. If it only had support for beryl, it would definately be my WM of choice.
@tmadhavan: You can indeed only have one exec line but you can execute any amount of commands before that line adding a '&' at the end of the line. The exec just defines the command that is linked to the XServer which means, if the 'exec' command exits, then the Xserver exits as well. But it doesn't have the WM you use with 'exec'. I once used a script I had written there, that allowed me to change the WM on the fly without shutting down neither X itself, nor any application I had running.

Kdemod 4.2 and dual head

I am trying to setup dual monitor in kde 4.2. I ran the command
xrandr --output DVI-0 --right-of VGA-0
but it doesn't work, I get an error msg
Xlib: extension "Generic Event Extension" missing on display ":0.0".
. Doesn't kde 4 support dual head?

what videocard are you using?
I have kde4.2 running smoothly on my nvidia-card with twinview
It's not yet perfect but it runs fine, there are still some problems if you want to use panels on both screens.
Also watch out with gtk-qt, here there are problems with gvim, openoffice, ... if you use it select the gtk style kde4-oxygen, then everything works fine

Sometimes dual head display is stretched
