Ubuntu Multimedia :: Lucid Upgrade Breaks Dual Monitor Set Up?
May 1, 2010
When Karmic came along, I upgraded and it was possible for the first time to get a dual monitor display working using only the GUI apps supplied. (I think I used screen resolution) It worked out of the box and took no time whatsoever.
I had a dual monitor set up working with 2 1024 x 768 monitors, with a desktop spanning both, and a background picture doing the same.
The Lucid update has just spectacularly broken this, along with a large number of desktop type changes that were unwanted.
The version of Ubuntu was the usual vanilla, but with enough K stuff installed to make K3b work. The card is a Radeon 9250SE.
Give up and re-install Karmic? Wait for some sort of upgrade to allow either Monitors or Multiple Screens to work - the option to remove cloning is greyed out in one and unticking clone in the other does nothing? Try some other distro?
Does anyone know of a decision to remove any functionality from Lucid that existed in Karmic? Is there any useful background to this that is perhaps not obvious?

So I've got this old Apple with an nVidia chipset. Don't know much about Apples, but from random searches on google I think it's an imac g5.
Anyway when I install Kubuntu 10.04 it works until I update it, then the video dies. It looks as though the nouveau driver is being killed and nv put back in it's place, anyone have any remedies I might try?

Hard details first:
EVGA nForce 750i SLI mobo
E8400 Wolfdale OC@4.23Ghz
2x GeForce GTS 250 1Gb
2x Acer AL2216W
Soft details:
-Upgraded from 9.10 to 10.04
-I did not have a working SLI config in 9.10
-No matter what fix I tried, only one monitor
-Was running "190.53" 64-bit drivers
-I had spoofed the xorg.conf file to get both working, but only with both plugged into one board, and no SLI option enabled
-Functioning 3360x1050 workspace with the ability to move open apps across monitors, but unable to switch between multiple workspaces

I upgraded a couple weeks ago and now my monitor doesn't go to sleep like it used to.
The settings in powermanagment show that it should go to sleep after 10 minutes.
Can someone point me in the right direction?

Upon upgrading from Karmic to Lucid, Everything comes up, seemingly fine. Once logged in to the OS, my three monitors show the desktop wallpaper as well as all the icons on the desktop. A few programs that I have set to autostart do so.
However for some reason, I can only access one of the three monitors. (And not the one with the gnome-panel.) As soon as I drag my mouse from my third monitor onto the one next to it, I loose complete control of it, and it starts dancing all over the place. If I try to drag a window from one screen to the next (using Alt-Left CLick + drag and not moving the mouse onto the other monitor), the the app goes from one side of the working monitor to the other side (like it's wrapping around). Though I can see it on the other monitor for a little bit until I get it far enough for it to wrap.
Here is my xorg.conf:
Code:
Section "Files"
FontPath "/usr/share/fonts/X11/misc"
FontPath "/usr/share/fonts/X11/100dpi/:unscaled"
FontPath "/usr/share/fonts/X11/75dpi/:unscaled"

I have the 32 bit lucid dual booted with win 7, and I wanted to upgrade to the 64 bit lucid. I have the .iso on a jump drive ready to go, BIOS is set to boot from it, now it gets funny. Unless I misunderstand what grub does shouldn't my jump drive show up in the grub menu so that I can select it to boot from? My only options showing are 32 bit lucid and wins 7.

I have a Intel DQ35JOE motherboard with integrated video (DVI and VGA). I've been running Ubuntu 8.10 for at least a year with both monitors working fine. One is a Hanns-G 27.5 inch, the other (VGA) is an older AOC 19". They were both plugged into the motherboard video plugs (it had both), and they worked side-by-side (not mirrored) just fine on 8.10.Last night I decided to go ahead and take the plunge and upgrade to the latest, because I run 9.10 on my laptop and love a lot of the new stuff. The reason I hadn't upgraded was because I feared the potential problems - which I ran into head-on this time.
Upgrade to 9.04 seemed to go fine. Then I immediately did the upgrade to 9.10. Unfortunately, my screens came up upside down and backwards. And the mouse moved the wrong way. And to click on something in the top left of the screen, I had to have my mouse on the bottom right of the screen.Well, I also received a warning that my primary hard disk was failing. So, I decided to just do a clean install of 9.10 on a new disk that I had handy - hoping it would be better if it was a clean install rather than an upgrade.
Now I can't get dual monitor to work at all, and Ubuntu seems to not recognize my monitors. If I just plug one monitor in, it works. But it won't let me adjust resolution above 1280x1024 (my big one is 1920x1200). And it says "unknown" instead of identifying the monitor.Also - at one point both monitors were appearing (but "unknown"), but mirrored, and whenever I uncheck "mirror screens" and click apply, the screen just goes black with a frozen cursor - and I can't even do CTRL-ALT-F6 to get to a terminal - it just freezes the whole computer.

I used preupgrade to upgrade from F11 to F12. In F11, I used the proprietary nVidia drivers from rpmfusion, and they worked well. I have refrained from installing the nVidia drivers in F12, because of the problems reported for users of KDE. I removed my old xorg.conf, which has references to the nVidia driver and to "TwinView," the proprietary method of managing two screens, so as to let X discover both monitors.
Now, however, my second monitor stays black, even though xrandr and KDE RandR show both monitors correctly. Xorg.0.log shows the nouveau driver is loaded. (I also tried to create a new xorg.conf following guidelines from the web, but many of the guidelines are from before xrandr, and I'm not confident I have it right yet.) It seems that X believes I have two monitors, because I can drag a window off into the blackness (and it's never heard from again!) I know that the hardware is working, because I just booted into Windows 7, and I could see the desktop on both windows.
How do I convince X and KDE to display on both monitors?

I'm having an annoying issue with my display configuration.
Some specs:
Motherboard: MSI 760gm-e51
CPU: AMD Phenom II 955 Quadcore
MEM: 8Gbs DDR3
VGA: ATI Radeon HD4850
ATI Radeon 3000 (on board)
All four monitors work fine with two X servers ( 2 monitors each instances) on Ubuntu 9.10 with surroundview enabled in the BIOS. I did a fresh install of Ubuntu 10.4 and all i get is 4 blank screens. when i disable surroundview in the BIOS with PCIE as default display the HD4850 work great. I should add that on both installs i used the latest atalyst 10.4. It seems like there's something wrong with Ubuntu 10.04.
Here's the xorg.conf of the working Ubuntu 9.10:
Code:
Section "ServerLayout"
Identifier "aticonfig Layout"
Screen 0 "aticonfig-Screen[0]-0" 0 1050
Screen "amdcccle-Screen[1]-0" 624 0

I am on kubuntu 9.10 x86_64
I just got my new video card: nvidia 9500 GT to setup dual monitors.
The video card has 2 dvi output to support dual monitors
Monitor 1 is connect to dvi
Monitor 2 is connect to dvi using a vga adaptor
I can't seem to get dual monitor to work?
From system settings -> monitor, i see 2 vid outputs one is DVI0, the other is VGA2. what's odd is i can set up different screen resolution for each monitor, but I only see one desktop, both monitors show the same desktop.
How do i get each monitor to show it's own desktop?

I noticed in the new Ubuntu 11.04 with Unity, when in dual monitor the icon of skype is not placed in the tray when "closed". It is only placed in the background, so that I have to kill the process and open a new one. To be sincere, I see a strange aspect of the entire tray when in dual monitor. Is anyone else noticing the same?

I have tried to setup a workstation with 3 monitors on two ati videocards, the goal being to span the desktop across all of them.
The process was not difficult at all, but after login X11 crashes and I am left with a console. I am fortunately able to login in safe mode, but I would like to ask for help in debugging this issue.
Here I will try to give as much detail as possible, starting with my system specifications:
Code:
The first card, the ATI Radeon HD 4650 is capable of running two monitors at the same time. The monitors, for all it matters, are three identical ACER P206HV 20" connected with their analog interface (due to missing cables which I will buy soon). Resolution 1600x900 each. My motherboard is an AsRock 870 Extreme3 mounting an AMD Athlon II X4 640 3 GHz processor and 8 GB of RAM.
When asked by Ubuntu, I installed the ATI Caralyst driver version 11.6 and set it up for using Xinerama.
As I said, this setup works fine if I login in safe mode, but crashes X11 otherwise (even in classical mode - no Unity). By inspecting the logs (attached) I found this (notice the segfault)
Code:
As a test, I tryed to configure Catalyst without Xinerama, an this works, but of course I end up with two separate desktop, which is not what I want. In this mode, xrandr seems to work correctly
Code:
After some research I found that XRandR does not support desktop spanning over multiple GPUs, so Xinerama is the only way to go in my case. Since the two are not compatible with each other, after login in safe mode I see that XRandR is disabled
Code:
One more test consisted in disabling the XRandR module in the config files, as found in some posts: edits in /etc/X11/xorg.conf
Code:
configuring the ati driver:

I'm having a rather hard time getting my 3 monitors setup as one display. I can get all three to work without too much heartburn using 3 separate X instances. The monitors are on 2 different video cards, one dual heads. The other on it's own card.
I've tried countless ways to get this to work, and I'm just not feeling the love. There are 2 17 inch monitors on the 1 video card and then the second video card has a 24 inch monitor on it. I can get the two monitors on one head to work with twinview, but the third one is left out.
The physical configuration looks like this..
17inch on the left of the 24 inch monitor, and another 17 inch monitor on the right, with the 24 inch monitor being in the center.
I'm going to include my current xorg.conf and lspci.
xorg.conf
Code:
harry@ubuntu:~$ cat /etc/X11/x
xinit/ xkb/ xorg.conf xorg.conf.backup

I'm trying to set up a dual monitor system with my Dell E7450 laptop with Debian Stretch and KDE 4.14.2. The graphic card is a Intel HD5500 with xserver-xorg-video-intel version 2:2.99.917-2. The first time I simply connected the HDMI plug, it recognized the monitor and it automagically set up the extended dual monitor. Then I unplugged the HDMI and KDE froze. Now every time I plug in the second monitor the laptop monitor goes black, the desktop goes on the external monitor and the mouse cursor moves only vertically along the leftmost edge of the monitor.

I have installed Ubuntu 9.10 on my laptop Lenovo T60. The problem is i can't make extended monitor in that way: laptop 1024x768 and Monitor LG L1952HQ 1280x1024. If i make this configuration, screens appear black and i can't go back without restarting. Presently system support only: laptop 1024x768 and LG L1952HQ 800x600. This configuration (laptop 1024x768 and LG L1952HQ 1280x1024) worked well previously with the same ubuntu 9.10 before reinstallation. I guess i should reinstall ore change to other video drivers? The refresh rate is set on 60 Hz.

I recently got a signal conversion box so I could route my netbooks monitor-out port to my TV. The idea being that I could effectively set the TV up as a separate monitor for watching movies on whilst I worked using the netbooks own monitor. It seemed to work initially, the Monitors dialog box could easily detect and setup the TV as if it were just an external monitor however I can't seem to play any kind of video on either screen when this is set up. All I get in Totem, Mplayer, VLC and skype is just a black area within the applications window. The sound works fine so this is clearly just a video problem.
It only seems to occur when I configure the system to use the TV as a separate monitor. If I tell it to display the same thing on both monitors all video output works fine.

Upon upgrading to Lucid from Karmic, my dual head setup doesn't work anymore with the new 2.6.32 kernel. In the previous kernel 2.6.31, everything works as expected (also when I boot Lucid with that kernel). On 2.6.32, the only thing I get is two clones. Is there some new type of configuration required that I missed or should I still compile some new kernel module???
My card:
Code:
rogier@rogier-desktop:~$ lspci |grep VGA
01:00.0 VGA compatible controller: ATI Technologies Inc Radeon RV250 If [Radeon 9000] (rev 01)

In Debian Jessie Gnome with two screens, I would like to execute
xrandr --output HDMI1 --primary --right-of eDP1
xrandr --output eDP1 --rotate left
prior to showing the GNOME user logon screen. Unfortunately, all information I seem to be able to find on this appears to be relevant for pre-systemd Linux only.
The situation is that I have two monitors: One small tilted monitor on the left with 1024 x 768 which should be secondary and one larger landscape monitor on the right with 1920 x 1080 which should be secondary. Everything works persistently AFTER a user has logged on. However, after booting the system or after changing users, the small monitor becomes primary so (a) the user needs to logon using that monitor and (b) as the monitor is physically tilted, one needs to tilt the head to read it wihtout the xrandr commands.
If I can get beyond this issue, there is a second issue: While one can pick the primary and secondary monitor in Gnome, monitor numbers 1 and 2 seem to be fixed. This becomes a problem when using freeRDP to connect to a Windows server with dual monitors. Then, the smaller, secondary monitor is number 1 and thus, it is the Windows logon and primary screen. Is there a way to switch numbers 1 and 2 in Linux, for example somewhere in the grub configuration?

I've played around with a second monitor, but so far I haven't found a satisfying solution. I am using a laptop with a GeForce 9600M GS graphics card. I have managed to set up twinview, but my monitors don't have the same height so I'd rather have something like the "seperate x screen" option. Or how I imagine that option would be like. After some problems with the nvidia configuration tool (I couldn't change the xorg.conf, until I read this: [URL] I now have two separate screens, but the second one is all empty, with black background and X-shaped mouse cursor.
There seems to be no window manager running, I can start programs there with -display :0.1 , but they don't get any frame decoration and, which is worse, no keyboard focus. I'd be fine with a fullscreen konsole there, so I don't really need a window manager, but I do need access from the keyboard. I'd prefer a setup that would allow me to easily (without editing xorg.conf) switch between using both monitors and using only one, because I don't always use the laptop at home.

I am running a 2.7Gh with 2G ram with an ATI X1300/1550 Radeon Card and running with dual monitors. I had the monitors functioning in Linux Mint but it was an older driver version and it was slow. I was reading about the Ubuntu Maverick 32bit and fresh installed it I have just installed Ubuntu 10.10 Maverick 32bit. Everything that I have found on here concerning ATI and fglxr has not worked.

I have a problem finding the resolution that will fit my secondary monitor(24). If I check "Same image in all monitors" I can only choose resolutions that laptop can display. I don't want laptop monitor to work when I'm using secondary monitor(I close the lid)...
If I want to uncheck "Same image in all monitors"(just to find the right resolution)...the system tells me to log out and back in again. When I do that, there's the same image on both monitors and the checkbox was automatically checked again...

I have an NVIDIA 9800 GTX. I have 2 DELL monitors connect to this card, one is a 24" and the other is 21".
I am unable to use Xinerama mode with Unity, because for some reason after logging in, I get no desktop interface, only background wallpaper, and I have to force reboot.
How can I setup dual monitors in Ubuntu using Unity properly? Note that I do NOT want to use TwinView, since this results in dead space around the smaller monitor.

I just installed Ubuntu 10.04 64 bit and I'm having a problem with the graphics card.
I have dual screens, and I'm using the default card. My Left screen is perfectly normal but my right screen has a black bar, roughly 2cm wide, along the left hand side of it. And that hole screen is shifted to the left 2cm (so if I maximise a window in it you can't see about 2 cm of the right edge).
I'm not sure why this is happening. Worked on Karmic. Haven't installed anything, just the defaults. My graphics card is a Radeon HD 4870.
Also, I couldn't get Compiz to work with this card on Karmic, is it possible to get it to work here on Lucid? I heard they were improving the drivers. If so, how?

A few days ago, I did a clean install of Ubuntu 10.10 onto a Mac. I dual-installed with Mac OS, and everything appeared to be going very smoothly. until I connected to an external monitor (a video beamer I use in my classroom). This led to:
a) the external monitor apparently being considered the primary monitor, and
b) compiz effects being disabled.
I addressed (a) by modifying the file monitors.xml in [me]/.config. (Before that. I had created a startup entry xrandr --output LVDS1 --primary. That also seemed to work; after changing monitors.xml, however, I disabled that startup entry, as it now appeared redundant to me.) Generally and for all I can tell, my actual computer screen is now correctly identified as the primary monitor -- from the moment I log in, at least. The log-in screen itself, though, appears on the external monitor, or not at all when that monitor is turned off.
This is the content of my monitors.xml file: I have not found any solution for (b): when I physically unplug the external monitor and reboot, compiz will run again; but once I plug in the external monitor, it won't.

The sound card is detected and it works since making the laptop boot from live CD (of ubuntu 10.10) I get sounds without problems. I tried to reinstall alsa-base and alsa-utils with no results. Everything looks OK, but the sound! (It's not muted!)

Just installed Debian 8, coming from Ubuntu12, it seems I cannot get my dual monitors to work as it should.
I want two monitors side by side, currently I have two identical outputs. I looked around a bit and register two possible problems.
root@bigcem101-debian:/home/bigcem101# xrandr
xrandr: Failed to get size of gamma for output default
Screen 0: minimum 640 x 400, current 1024 x 768, maximum 1024 x 768
default connected primary 1024x768+0+0 0mm x 0mm
1024x768 0.00*
800x600 0.00
640x480 0.00
720x400 0.00
Hence, problem 1: it is as if there is only one monitor detected. Then I tried to look for Xorg.conf ..... and: problem 2 xorg.conf is not there. This seems to be normal but when I installed my Ubuntu years ago it was still there and one could manually set things. There must be something new I am missing.
Card:
VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] RV670 [Radeon HD 3690/3850]
It seems I have both ati and radeon installed.
root@bigcem101-debian:/home/bigcem101# X -configure

Fatal server error:
