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?

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.

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.

[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.

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

Black screen with dual head with kernel 3.7

When I boot my (rather old) laptop with a VGA screen attached, the main LVDS screen goes totally black (with no backlight) at loading the module i915 and the VGA screen goes black (but one can see the backlight is on). When I boot without the VGA screen attached all is normal (and I can plug it afterwards). In the first case xorg does not start (or is not visible).
I have no problems with previous kernels or with the lts kernel if I pass the VIDEO=SVIDEO-1:d kernel parameters (otherwise the screen goes black when I attach no screen).
Anyone having such problams, any workaround. For the moment, I just use the lts kernel.
Relevant output of lspci:
00:02.1 Display controller: Intel Corporation Mobile 945GM/GMS/GME, 943/940GML Express Integrated Graphics Controller (rev 03)

Regression in mesa? with dual head

Since some time I'm experiencing errorrs when I maximize an application on the second monitor. Gnome3 will crash with 'Snap' if it cannot recover a restart (which it will try first). In the logs I find:
apr 05 15:33:33 arch kernel: radeon_gem_object_create:69 alloc size 131Mb bigger than 128Mb limit
The setup is an Acer laptop with onbard ATI Radeon 5250 with 1Gb shared memory. The laptop screen is 1600 x 900. Attached to the HDMI port is a 1920 x 1080 monitor.I'd run stock kernels with xf86-video-ati driver.
Searching Google doesn't reveal much. [1] is a Fedora bug describing even more troubles with three monitors. Watch comment 17 where he starts describing exactly my issues.This bug report suggest that a patch by Jerome Glisse [2] might actually solve the issue. The patch is called "mesa-9-r600g-limit-memory.patch to fix relocation issue" which sounds like it could be the cause of it all.
At least I have a lead. It may be Mesa. I installed mesa-git [3] from AUR but no luck. Downgrading Mesa didn't work due to many cross-dependencies. I subscribed to the mesa-master mailing-list [4] but no patch drew my attention.
Later Google search revealed another possibility. I found this patch for Linux kernel 3.7.6 [5] called 'drm/radeon: move size limits to gem_object_create'. That may be the start point of the bug, but I'm running the latest kernel (3.8.x) so that's no solution.
My main question is: where to go from here?
[1] https://bugzilla.redhat.com/show_bug.cgi?id=896170
[2] http://web.archiveorange.com/archive/v/ … SYN59QSbNc
[3] https://aur.archlinux.org/packages/mesa-git/
[4] http://lists.freedesktop.org/mailman/li … esa-commit
[5] https://www.kernel.org/pub/linux/kernel … og-3.7.6-1

The patch is not in current mesa. I just cloned it (git) and checked for the first method which I couldn't find,
I had the suspicion this is a Fedora patch, but Googling I thought I saw it in Xubuntu also. Not sure about the latter.

Dual-head with Radeon HD 2400LE not working/behaving strangely

I have a Radeon HD 2400LE video card. and I'm attempting to set up dual-head with a 17" (1280x1024) scree and a 24" (1920x1200) screen. I originally tried fglrx, and it worked mostly, but caused partial lockups every few hours (the mouse cursor would move, but didn't seem to pass any events to anything - even hover wouldn't work). I'd like to use the radeonhd driver in any case, and I'm currently trying it from git/AUR, version 20090116-1. I'll post my xorg.conf here shortly, once I've cleaned it up a bit. Anyhow, I'm running KDE 4.2, and the display settings list VGA (my second monitor), DVI-digital (my first monitor), DVI-analog (the same port), and TV (S-Video - not used). However, clicking "Identify Outputs" displays the VGA output properly, but the DVI-digital output indicator is shown halfway off the top-left corner of the VGA-connected screen. Enabling the DVI monitor's output does something, because the monitor recognizes that it's connected, but it won't display anything, and changing the DVI settings causes various weird issues with the VGA-connected screen. I'm not using Xinerama, as I was planning on doing the whole thing with KDE and the help of XRandR. I could really use some help with this, as I've been fighting with dual-head all week.
Thanks

Here is my xorg.conf, it sounds like you are trying to acheive a similar setup to what I have, maybe you'll find this helpful

[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.

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.

[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!

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 ?

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

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.
[foosoft@asakura ~]$ xrandr

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.
Here's my xorg.conf:

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

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
Current serial number in output stream: 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.)

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:
