Fedora Hardware :: Dual Monitor/nv/nouveau Does Not Work
Jul 4, 2010
I have just upgraded from Fedora 11 to Fedora 13 and now can't get my two monitors working as a single "screen" (it worked under F11). I have a GeForce video card with two monitor outputs
lspci -v
01:05.0 VGA compatible controller: nVidia Corporation G73 [GeForce 7600 GT] (rev a2) (prog-if 00 [VGA controller])
Subsystem: Device 1acc:0846
Flags: 66MHz, medium devsel, IRQ 16
[code]...
I then edit the xorg.conf to change the driver from nouveau to nv and I can start X and the LCD displays the desktop at a resolution of 1680x1050 (good) but the CRT just displays random blocks of colour. At this point I also get a kernel crash - see dmesg output attached, but the system is then OK to use. I have tried editing the xorg.conf to add a second monitor and a virtual screen resolution to match the two monitors (1024x768 + 1680x1050) combined (2704x1050) but still only the LCD monitor works, but with the virtual desktop that can be nudged around with the mouse. I would like to get back to using both monitors with a virtual screen across the two monitors.

I've been troubleshooting a friends computer and we've pretty well hit a brick wall. The issue at hand is the video card will not output properly. To be specific, it's an NVidia card with both DVI and VGA ports. We want it to output via the VGA and ignore the DVI because there's nothing plugged in there (the monitor we want to use doesn't support DVI). At any rate, the only time we can get the VGA to work is when we have another monitor plugged into the DVI port and dual head the system. When we do this it also adds an extra "Unknown Monitor" to the display panel. When we just use the DVI the extra "monitor" disappears. now we don't want to have monitor sitting here useless just so we can use the vga out, but there seems little else to do. We tried installing the Nvidia proprietary drivers through the software manager and yum and it failed both ways.
This is really frustrating because it seems like it should be such a simple thing but nothing works. Does anyone else have similar issues? is there something i can do to fix this? I apologize if i've not provided enough info, but ask and i'll post anything you need to diagnose.

I am having a problem with the nouveau driver in Fedora 15 Code: lspci | grep VGA 40:00.0 VGA compatible controller: nVidia Corporation NV41GL [Quadro FX 1400] (rev a2) The problem is that when I boot a Fedora 15 live Cd, either gnome or xfce, the monitors initially seem to work in that they display at the proper resolution, both as the CD boots and as X initially starts. I can see the background and the mouse cursor - it is "busy" ...
As the desktop finishes loading, however, my primary monitor becomes disabled. With gnome the screen goes black, with xfce it goes white. I can still see the mouse on my secondary monitor, but I can not seem to open any applications (such as a terminal) or change to a console (ctrl-alt-F1 or ctrl-alt-F2). I can boot into safe mode. Adding the boot option video=xxx sets the resolution on the console as it boots, but does not help running X.

I've got a "little" problem with fedora 13: dual head with nouveau is not working. gnome-display-properties recognizes two displays and i can configure it (left, right, mirroring, ...) but first display is always in standby. Seems it doesn't get a signal from graphics controller. Desktop seems to work fine (can move the mouse pointer on the other screen into "the black hole"). I use Fedora 13 x86_64.

I have two monitors - one connected to the VGA port and the other to the DVI port. Fedora seems to be detecting both monitors (figured this out because when I rotate the desktop cube, the second screen is also seen.). However, the monitor on the DVI port is blank. This happens even if I use just one monitor with the DVI port. I cannot install the proprietary nvidia drivers because my computer hangs (has been happening since fedora 11 or 10), Is there a way to get both monitors to work with the nouveau driver?
I faced this problem in Fedora 13 as well and was hoping both screens would work out of the box in F14. Is there any way I can do this to make it work like nvidia's TwinView?

I just upgrade to F14 from F10 on a dual montor setup. Firefox behaives differently on F14 than on F10.
On F10 it followed the mouse pointer's location and show up on the correct monitor
When maximized at close, it is always displayed on the left monitor. When not maximized at close it will open on the monitor where the mouse pointer is located.
About minimize/maximize Firefoxe before closing and it seems to work in some case, but not for me.

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 read that the Nouveau Gallium3D driver will work with Nvidia cards in Fedora 13 (YAY!)What I was wondering is this - will the driver work in 12 or will I need to get 13?

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 have Fedora 11 installed on a system that initially had an ATI 1650 type card. I recently replaced it with a GeForce GT 220. I don't believe there was ever an xorg.conf generated or used with the ATI card. Initially, when I replaced cards and rebooted, I was able to start up KDE or GNOME but with only 2 very low resolutions available(the highest being 800x600). Next I ran Xorg -configure to generate an xorg.conf file. Everything I am seeing in this file seems to make sense. But now, when I startx all I get is a red error box being displayed by the CRT monitor with this message:
Signal Frequency is out of range
FH 30.1 kHz FV 24 Hz
Please Change Signal Timing
The only way I can get my X system back is to go into the xorg.conf file (in the Device Section) and change the driver to vesa. But I still only have 2 very low resolutions available.

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.

When ever I install the (recommended) drivers through the "Additional Drivers" interface to run Unity my dual monitor setup does not work. The monitors won't even detect correctly what so ever. Then, when ever I install (more basic?) nVidia drivers through the packet manager, my dual monitors work as planned, but now Unity won't work. What's the deal? Are there any work arounds for this?

Pressing left, middle and right button of mouse at bottom and right edges or bottom left, top right and bottom right corners of the screen does not work with fittstool-2.0 on openbox in debian jessie with dual monitor.
Pressing left, middle and right button of mouse at top and left edges and top-left corner on the screen works correctly.
I use openbox on debian jessie. I do not install any desktop environment explicitly.
In the jessie, I installed gcc, make, libglib2.0-0, pkg-config, libcairo2-dev and libxcb1-dev.
I downloaded [URL] .... and confirmed that the sha1sum value of the downloaded file matches sha1sum value given at [URL] ....
I expanded the downloaded file by
Code: Select alltar -xvf fittstool-2.0.tar.gz
into fittstool-2.0 directory.
I executed with an ordinary (non-root) user:
Code: Select allcd fittstool-2.0
make
I executed with root privilege on the fittstool-2.0 directory
Code: Select allmake install
I executed the following with the ordinary user:
Code: Select allfittstool
and ~/.config/fittstool/fittstoolrc was generated.
I modified it as
Code: Select all[TopLeft]
LeftButton=gnome-terminal
MiddleButton=pcmanfm
RightButton=iceweasel
[Code] ....
gives:

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 am attempting to use dual monitors in Fedora 14 using an AMD ATI Radeon HD 5700 Series graphics card (not that I think that has anything to do with anything, but who knows), and want it to where my second monitor is its own virtual workspace so that I can switch between my other workspaces on my original monitor without switching the workspace on the second monitor. This way, I can watch movies or what-not on my TV (2nd monitor) while working on my original monitor.The only thing I found that was even close was setting the 2nd monitor up on it's on x server, which I don't want to do. Also, as it is now, I have my panel on my original monitor, but the windows do not see it when I have it aligned on the right (the windows don't adjust their size to account for the fact that it is there). I know a way I can do a work-around for this, but I would like to know if there is a "correct" way to do this. I know I can tell the movie player to show on all workspaces and have it on the 2nd monitor.

I am having problems getting my external monitor to work. When I plug in the monitor, both the laptop screen and the external monitor go black. When I unplug the monitor, the laptop screen works again.
When I startup with the external monitor plugged in, neither screen works or teh computer hangs or something.
I have had the external monitor going on a couple of occasions. I did manage to configure my monitors through System Settings > Display. I turned off the laptop monitor as I just want to use the external. But after rebooting, things didn't work.
I have a Thinkpad E420, Fedora 15

Long time reader, first time poster to the forums. I have installed Fedora 12 onto a desktop here. Fresh install and fully updated as of today. In this system there is a radeon 7000 graphics card that Fedora set up dual display for me. This is working fine but unfortunately im seeing a problem with the top and bottom of one of the displays.
Please see the problem here: [URL]... The mouse will go underneath or above the areas i have pointed to. Any ideas what is wrong? In fedora 9, 10, 11 this was all working fine but i did have to use xrandr manually to get dual display working. Edit: Update:
I dd not mention that i kept my home directory. On futher inspection it seems that the issue is because of a .folder in my home directory that was backed up and restored on the fresh install. To check this i added a new user to the system and logged in with a fresh home directory. Does anyone know which folder or file this setting this is stored? I tried logging out, moving .gconf .gconfd .gnome2 .gnome2_private and the .gtk folders to another location then logged in to no avail.

I know there are a lot of dual monitor threads.I've read them, and I even checked at the nvidia forum.I don't see something similar enough to my problem so I'm thinking maybe it's not a driver issue.I'm running F12, both monitors were working and I configured them properly and they were fine.Yesterday I installed the nvidia drivers as per Leigh's tutorial.Once I got that sorted out and rebooted, my secondary monitor was no longer registering.I checked in display settings and it does not recognize the second monitor.I tried going to system->administration->display but after I authenticate nothing happens.

I am running Fedora 13 on a PC I built myself - MSI motherboard 785-E53. It has onboard DVI which my primary monitor is hooked to. I added an older 17" CRT to the onboard analog output and the main desktop with my icons and panels immediately switched to the CRT. Kernel is 2.6.34.7-66.fc13.i686, lspci -v says VGA compatible controller ATI Technologies Inc RS880 (Radeon HD 4200). How can I get flatscreen on the DVI output to be the primary?

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've started playing around with debian 6 stable, and was just wondering if its worth it to go to the trouble of removing nouveau, or if it will handle everything well enough. I use my laptop for a little bit of gaming (older games) under wine, all the basic email/web browsing/writing stuff, some photo editing under gimp, movies/music, and a very little bit of Blender work.Will Nouveau handle all this well enough, or should I use the proprietary nvidia driver?

just setup suse 11.3 , put on the Nvidia 19.29-22.1 drivers via yast , no kms is set in inetd , nomodeset on grub boot line etc... Even tried installing the driver " the hard way " dual monitors come up, setup xinerama to "Extend" my desktop , and the main monitor ( right side ) is good, visually the left monitor (2ndary) is good.. but whenever I move my mouse over to the left screen the mouse pointer dissapears, flickers along the right hand border of that screen... and if i move the cursor back to the original screen i have to really fight to get it back to the main screen....Copy of my xorg.conf , still very basic...

I was using dual monitor on my Fedora 14. I followed leigh123linux's instruction and I was successful. However I cannot use the dual monitor any more - just see the cloned two monitors... I suspect something happened during update. ATI catalyst control center says I need to run it as superuser, but I do not know how to.

I have recently installed FC15 on my system. Dual monitor support seems to be broken with my setup. I am using the latest NVIDIA binary blob driver (270.41.19). I compiled my own kernel for it, version 2.6.39.
When gnome3 starts it almost manages to boot up, but then it crashes and gives me the option of logging out. I have my system booting into target 'multi-user.target' since I was doing some other stuff and I use `startx' to start gnome3. I tried running having X use xinerama and not use xinerama, both cause gnome3 to crash, albeit in different ways. Other than that I am running a stock install as far as I know.
If there are some logs I should be looking at for gnome3.

I recently upgraded to fedora 12. Before the upgrade I had a desktop background which filled the entire 2 screens. After the upgrade i noticed that the background is displayed on each monitor twice so when displaying the desktop I see the background twice.I tried to change the settings for it like 'center' and 'fill screen' but to no avail. The rest of the dual monitor setup works fine.

I have a dual monitor setup in Ubuntu, with my main monitor on the right and the monitor I want to extend to on the left monitor, but I can't seem to get it to do this, it always has the 'desktop' on the left monitor and then extends onto what I want to be my main monitor. I have an ATI Radeon 4350 Graphics card.
