Dual Head Setup [VGA 1440x900, HDMI 1600x1200]

Hi,
first of all, I have to say that this is my very first time to real use arch. I'm here to get to know arch and to learn as much as I can, so I want to create a real desktop with 2 physical screens.
The first one is connected via VGA, its best resolution is 1440x900.
The second one is connected via HDMI, its best resolution is 1600x1200
I use i3 and got the HDMI screen working, with 1600x1200. native, in using xorg with the
xf86-video-ati driver.
The right screen, my HDMI (the larger one), shows the correct resolution. The left one shows me out of range.
I pacmaned xrandr to try to get some hints:
xrandr: Failed to get size of gamma for output default
Screen 0: minimum 640 x 400, current 1600 x 1200, maximum 1600 x 1200
default connected 1600x1200+0+0 0mm x 0mm
1600x1200 0.00*
1280x1024 0.00
1024x768 0.00
800x600 0.00
640x480 0.00
720x400 0.00
First I thought of creating an own xorg.conf in /etc/X11/xorg.conf and later I got in my mind to use xrandr --mode to set the correct resolution.
Which one of these ideas is the correct one? Do you got a better suggestion for me? What do I have to do to reach my correct resolutions. It seems to me that the screen is handled as beeing one. Cause when I change xrandr default resolution, both screens change its resolution.
Hope the best for your help :-D
cheers

There is no "correct" one. If it works, it's correct. xrandr is the probably the easier of the two, so stick with that if it works.

Frozen system when booting with dual-head setup (updates)

Hi guys,
I made a fresh install a couple of weeks ago and I configured my system for a dual-head setup following the wiki. I activated KMS and added radeon to the kernel parameters.
My xorg.conf looks like this:
Section "Monitor"
Identifier "DVI-0"
Option "PreferredMode" "1920x1080"
Option "Position" "0 0"
EndSection
Section "Monitor"
Identifier "HDMI-0"
Option "PreferredMode" "1920x1080"
Option "Position" "1920 0"
EndSection
I was having random freezes for a couple of days, but I didn't pay too much attention to it. I hard rebooted my computer when it froze and it could boot normally that second time.
But after yesterday, last update to the open source drivers xf86-video-ati (1:7.5.0-2) and lib32-mesa-libgl (10.5.2-1), my system doesn't boot unless I disconnect one of the screens. When only one screen it's connected everything is fine. If I plug the second screen, it pops up the KDE service to configurate the second screen but as soon I press 'apply the chages' my system freezes and I had to hard reboot.
I've tried all possible combinations usingt different outputs from the screens, getting the same results. Two of them connected --> freezes after grub loading. One connected --> boot Ok, but as soon as I plug the second one and I apply changes, freezes.
I found one configuration that doesn't freeze my system. When I plug the second screen, as I said, KDE service automatically pops up. Before I was changing the positions of the screen, one beside the other one, and my system freezes when I apply the changes. If I just left the default configuration (one screen in top of the other), it doesn't freeze my system. After that, I can rearrange the screens, as I need them, and it doesn't freeze.

Downgrading catalyst to 14.3 seems to have done the job. Thanks for the suggestion, marking as solved.

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.

[Solved] Catalyst graphical glitches with dual head setup

Hello all, having a weird issue with my dual monitor setup where graphical glitches make my primary monitor completely unusable. The Tear Free feature of the proprietary catalyst driver is what seems to be causing it:
Tear Free enabled:
Tear Free disabled:
I can safely enable it with one monitor disabled also. The issue is that without Tear Free enabled, I'm experiencing some serious screen tearing when watching videos and playing games.
My video card is the XFX HD 7970 Double D and I'm using the latest version of catalyst (14.4), installed from Vi0L0's repo. The monitors are the same model with the same specs (1920x1200 @60Hz). I definitely used to be able to use Tear Free with my dual head setup at most a month ago, so some update at some point must have broken it. I temporarily switched back to the open source driver before I had found Tear Free to be the culprit and the performance is still hardly comparable.
Any ideas? Thanks in advance.

Bootsplash on a dual-head setup without KMS?

Hello!
I have been wanting to get a bootsplash working on my system, to get a feeling of a more polished system, but sadly I'm running the catalyst drivers for decent 3D game framerate, and it doesn't support KMS. It seemed like that would have been okay, and that for example plymouth could work through a framebuffer, but sadly I have dual-head with two different resolutions(1920x1200 and 1020x1280), and I couldn't get Uvesafb/v86d to work with that. I really want to get a bootsplash and I am willing to sacrafise some time to get it working. The main goal is just to get it working, but ideally I'd like it without any resolution changing or black flicker, as it's described here. So Plymouth is my first-pick, as it looks "best".
So far I have tried Splashy, FBsplash and Plymouth, with different degrees of success:
FBsplash:
Miscsplashutils(dependency) didn't build because freetype had been built without static linking(I don't know anything about this). I got it working with something I found in the comments though.
But then FBsplash wouldn't build. And I gave it up.
Splashy:
Installation worked(splashy-full) after I modified the PKGBUILD with some automake patches so it should work with automake 1.14. But when I booted it the screen was just flickering black
Plymouth:
I got it installing, can't remeber if I needed some patches. And it worked, although only with a text-bootsplash. I also installed a framebuffer(Uvesafb/v86d) but that didn't work properly.
The Plymouth loading anymation(spinfinity) continued into gdm.
I am willing to retry everything and clearify what doesn't work, and why.
Thanks to anyone who can help!

So I've been trying to get some development on this, and used most of the day to get uvesafb working.
It is working quite good, but I don't get the native resolution of the screen(1920x1200), I only get 1600x1200.
And my secound monitor is disabled, I suspect it's because the computer sends a resolution to big to both the screens, but it's really a a feature for me, as the terminal would be sideways on the secound monitor anyways.
During my testing I also came to a new idea: Have the framebuffer, X and GDM originally only start the main monitor, and then leave it up to gnome to enable it. that way I would only get the flicker between GDM and gnome-shell, which I will get anyway, because it seems like everything ignores X's rotation of the screens, or at least doesnt support sideways. However I didn't find a way to get this working, any ideas?
EDIT; My card is an HD6790, and as far as I can understand the GPU's bios is sending supported modes to uvesafb?

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:
ismaelvc@toybox ~ $ xrandr -q
xrandr: Failed to get size of gamma for output default
Screen 0: minimum 320 x 175, current 1024 x 768, maximum 1024 x 768
default connected 1024x768+0+0 0mm x 0mm
1024x768 87.0* 85.0 75.0 70.0 60.0 81.0
832x624 75.0
800x600 85.0 75.0 72.0 60.0 56.0
640x480 85.0 75.0 73.0 60.0
720x400 85.0
640x400 85.0
640x350 85.0
512x384 87.0 85.0 75.0 70.0 60.0
416x312 75.0
400x300 85.0 75.0 72.0 60.0 56.0
320x240 85.0 75.0 73.0 60.0
360x200 85.0
320x200 85.0
320x175 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.

Xorg 6.8 and dual head setup

Hello,
I have a laptop with an ATI 9600 mobile chip which ran in xinerama mode fine for the previous release of xrog or xfrree86 but with the new xorg reslease 6.8 I can no longer run 2 monitors. It will run fine in single head mode, but it will no longer run in dual mode. In fact, it "seems" to run faster and take less memory in single head mode,
I am posting my xorg.conf in the hope that someone can help!

Thanks,

Hello,
I have a laptop with an ATI 9600 mobile chip which ran in xinerama mode fine for the previous release of xrog or xfrree86 but with the new xorg reslease 6.8 I can no longer run 2 monitors. It will run fine in single head mode, but it will no longer run in dual mode. In fact, it "seems" to run faster and take less memory in single head mode,
I am posting my xorg.conf in the hope that someone can help!

Grub/boot using wrong monitor (dual-head setup)?

I have a dual monitor set up, using two dvi slots on my radeon HD card.
When I start up my system, regardless of the order of the cables, it first shows my bios slash screen on both monitors, then it goes to Grub2 and I see "Loading Grub.." on both monitors. After that, it always defaults to displaying on my "secondary" monitor, which I do not use very often. Meanwhile my primary monitor goes black until my system reaches the SLIM login.
Is there any way to define which monitor is to be used in Grub2 and during booting?
I'm thinking it the default display may be configured in the /etc/grub.d/00_header file but I have no idea how to edit that.
As I said, I tried switching the cables and also checked the bios and didn't see any settings regarding this.

The primary display is the one that holds the tiny white stripe representing the MenuBar in this presentation in system Preferences > Displays:
Drag the white stripe to the display you would like to be Primary.

Touchscreen dual head setup help needed

I'm trying a rather complicated screen setup, with a 17" touchscreen (1280x1024) and a 24" widescreen (1920x1080). Using the opensource ATI driver.
The touchscreen works on it's own, and cloning works, but looks ugly on the 24". An extended desktop works too, but then the touchscreen's coordinates are scaled over the vitual screen, so touching on the middle causes the cursor to move somewhere on the 24".
Currently I'm trying a separate X screen setup, but it appears to be broken in the latest Xorg, which seems to require using xrandr. Can someone confirm this?
Is there any way of limiting the touchscreen cursor input to the 17"?
This is a new system, so I'm also open to WM suggestions.

Looks like I'm missing an option "screen" in evtouch. I'll test it tomorrow. And post the details if I'm successful, because there is not much information to be found.

[Solved]Dual-Head Setup broken after last Kernelupgrade

Hello,
Yesterday I upgraded my from 4.0.2 to 4.0.3 and was kind of surprised when my second display didn't want to show a picture anymore. When booting everything looks good when sudenly one display gets black. It doesn't matter which Desktop I start, even when switching VT only one display is active, so it's not a Xorg-bug.
Nothing shows up in journalctl oder dmesg and as far as the system is concerned everything works as expected. Everything worked as soon as I downgraded the Kernel to 4.0.2.
Enabling testing and installing 4.0.4 didn't work either.
So my question is, does anyone else experience this behaviour?
thanks in advance
- Radeon HD 77xx with open source drivers
- two displays DVI (primary) and HDMI (secondary)
Edit:
I Just checked the kernel from today in testing (4.0.4-2) and saw something really interesting during boot.

I think I kinda 'solved' the problem by enabling early KMS in mkinitcpio.conf and switched my first Display to the second DVI-Port. It works now, but I don't know if this could be labeled as 'solved' since it's a pretty specific solution and propably doesn't apply to anyone else.
Edit. The most recent Kernel 4.0.5 in Testing solved the problem for me.

KDE 4.1 with irregular dual head setup -- recommendations, suggestions

Hello,
I'm running KDE on a laptop with a 1440X900 screen and a 1280X1024 external monitor.
I couldn't get the KRandR to split the desktop onto two monitors, but plain xrandr worked fine -- the desktop is split, the external monitor is on the left, and resolutions are as they should be.
However, I'm having some problems/quirks with KDE 4.1 --
1. When both monitors are on, KDM's login window is on the left monitor, not the primary one (the one on the laptop).
2. When filing mail in Thunderbird, the contextual menus will trail off the bottom of the screen below the task bar, rather than reposition themselves to remain visible
3. The plasmoid swirly thing is in the upper right corner of the left monitor, but not the monitor on the right.
Thanks,
Chris

Set default boot display in dual-head setup

Hi,
Mac Pro 2010 with AMD Radeon 5770. One display attached via DVI, the other via DVI plus a DVI-to-DisplayPort adapter cable.
No matter which way I plug these displays in, it's always the display I consider to be the secondary one that displays the boot screen, and FileVault 2 FDE password prompt. This display is seldom switched on, and I have it disabled during daily use using SwitchResX so that my pointer doesn't stray. Having to switch it on purely for the purposes of boot is frustrating.
So, is there some fail-safe way to force the boot screen and FDE prompt to always appear on the primary display? I found a thread that reported using PRAM or NVRAM resetting to contrive this, but it transpired that it was not a permanent fix.
Please, don't recommend I simply unplug the secondary monitor.

The primary display is the one that holds the tiny white stripe representing the MenuBar in this presentation in system Preferences > Displays:
Drag the white stripe to the display you would like to be Primary.

[solved] Dual head / Xinerama / xrandr setup with Intel 945 & dwm

Recently came into possession of a 17" LCD and would like to use it in tandem with the internal LCD of my netbook. Clone works with xrandr, as does extended mode to an extent. The problem is that in extended mode (or spanning, or whatever you want to call it) the smaller screen has dead space which isn't respected by dwm (or any other WM I've tried). So I'd like to setup dual X sessions (aka Zaphod mode?), each running their own instance of dwm--I don't need to move windows from screen to screen so that's not a concern.
Has anyone had luck accomplishing this with the current intel driver? The closest I've gotten so far is a black screen/blinking cursor which drops back to a login prompt after a few seconds. I see a ton of related topics on Google about this and most of them are unresolved. If I can get something put together I'll document it in the dwm and/or intel wikis.
Specs:
* Acer Aspire One AOD150 with Intel GMA945 @ 1024x600
* LCD @ 1280x1024

It's a work in progress, but for those who are interested I was able to get a dual-head setup (using xrandr and the Xinerama extensions) with the current Intel driver (not legacy) using the following:

Until I have a chance to write a fancier script I've added the following to ~/.xinitrc:
xrandr --output LVDS1 --mode 1024x600
xrandr --output VGA1 --below LVDS1 --mode 1280x1024
The first command ensures the netbook screen takes the proper resolution and the second enables the external LCD. If I startx when the LCD is disconnected then the netbook screen is the only screen enabled (no dead space).
Caveats
1. With mplayer in fullscreen it appears as 1024x600 even when opened on the 1280x1024 screen.
2. The external LCD cannot be placed left or right of the netbook screen because it would exceed the 2048 virtual resolution which segfaults X with the latest intel driver. Virtual cannot be set higher than 2048 in either direction without segfaulting X; though I imagine this will be addressed in future versions of the intel driver.
Many thanks to mzapotoczny!

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?

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
