Ubuntu :: Three Monitors - Xinerama And Cannot Get Desktop Effects Running At Normal Or Extra

Feb 28, 2010

Currently I have a perfect setup of 3 monitors,2 GPUs running under Xinerama. I cannot get desktop effects running at Normal or Extra, when I try to enable either one I get the following message "The Composite extension is not available". Without Xinerama it works along with Compiz. I am running Ubuntu 9.04 x64 with a ATI HD4870 and ATI HD4350 GPU. I have the latest ATI display drivers (set up properly to my knowledge). Here is my xorg.conf file.

Ubuntu :: Can't Enable Normal Or Extra Desktop Effects

Aug 16, 2010

I have Lucid lynx on my laptop, its been working perfectly for months. Recently been trying to get flash videos on sites to play and came across a 'fix' that said to disable desktop effects, which I did.

That didn't work and afterward found out that adobe flash 10 don't work on 64-bit linux, which is what I have. Tried to re-enable desktop effects to normal but got "cannot load desktop effects" popup.

I've removed nvidia driver, reinstall it, tried to enable desktop effects, didn't work. Ran nvidia-settings which said to run as root nvidia-xconfig and restart X(alt-printscr-k), which I did, it didn't work. I just want my desktop effects back, I had it on extra.

Edit: Forgot to mention that at boot, after grub menu nothing shows. No login screen. I have to add "nomodeset" by pressing e at boot menu and typing it to the boot options to get a dialog to choose restart x which then shows the login screen.

Update: I've been searching all over, tried to install by downloading from nvidia site, didn't work, been rebooting like crazy after every try. Installed a bunch of nvidia files from software center and got hardware drivers to have nvidia current. The driver is activated and in use. However I still can't enable desktop effects and ubuntu doesn't boot normally. After the grub menu it shows the logo for a second then blank screen. I have to boot with nomodeset and choose to restart x or start in low graphics mode.

Please help me fix this.

OpenSUSE Install :: Xinerama Config - Adjust Xinerama To Place 1 Desktop On Each Of 2 Monitors And Not Stretch A Single Over Both

Jan 10, 2010

I would like to adjust Xinerama to place 1 desktop on each of my 2 monitors and not stretch a single over both. With the current set up there is a problem with window placement upon opening new widows or context dialog boxes. I realize that I could adjust placement properties and select window placement with the mouse but this is still lacking in productivity. My monitors are not next to on another so this is more of a problem than it seems.

Ubuntu :: Xinerama With Triple Monitors - 11.04

Jun 21, 2011

Did a new install with a system that worked well on 10, with Xinerama. I have nvidia 9500 GT cards, but I dont think its driver related. Screen 0 is the center Screen 2 is to the right And Screen 3 is to the left.. When Xinerama is disabled things work flawlessly, but not using Xinerama is a killer to me. The nvidia configuration utility generates the following xorg.conf when Xinerama is disabled. It gets the locations right and the mouse moves correctly between screens.

Ubuntu Multimedia :: ATI Radeon - 2 Cards And 3 Monitors (Xinerama)

May 21, 2010

After working on trying to get my 3 monitors to work with Ubuntu 10.4 and my ATI Radeon HD3200 (IGP) and HD4850 cards, I just had to share the xorg.conf. I am using the default open source drivers that came with 10.4 and I kept KMS enabled (it wouldn't work without it).

Here is my conf:
Section "ServerLayout"
Identifier "X.org Configured"
Screen 0 "4850-2-Screen"
Screen 1 "4850-1-Screen" RightOf "4850-2-Screen"
Screen 2 "3200-Screen" RightOf "4850-1-Screen"
InputDevice "Mouse0" "CorePointer"
InputDevice "Keyboard0" "CoreKeyboard"
Option "Xinerama" "on"
#OPtion "Clone" "off"

General :: Xinerama - 3 Monitors Setup (Slow And Laggy)

Dec 23, 2010

I currently have my monitors set up as an extended desktop using Nividia's Xinerama function. Everything works sweet, except it's acting slow and lags out. It all works out fine when Xinerama is disabled. At the moment, I'm using CentOS with Gnome, but I've tried other distributions with the same outcome. If I can't a fix I'm going back to windblows.

Computer specs:3 monitors
2 Nvidia GTX 275 GFX cards
EVGA 4-way Classified motherboard
12 GB ram
CentOS - with Gnome

OpenSUSE Install :: 2 Monitors (xinerama) With NVIDIA GeForce FX Go5200?

Nov 29, 2009

On openSUSE 11.1 I was able to configure KDE 4 for 2 monitors with sax2 (although the resolution was bad).On 11.2 neither SAX2 nor KRandR seem to work. The KDE User Guide says that a driver supporting version 1.2 is necessary. However the nvidia driver for eForce FX Go5200 seems to support only version 1.1.Is there a way to use both monitors with SUSE 11.2? I am quite desperate since for my work using only 1 monitor is definitely a handicap.

Hardware :: Triple Monitors Xorg With AMD&NVIDIA: XRANDR And Xinerama Not Working?

Mar 24, 2011

I'm trying to set up a tri monitor setup. Unfortunately I must use 2 cards, one an AMD HD4350 and a PCI Geforce FX200. (Old skool I know) Due to the restrictions, I am forced to use the open source drivers (else nvidia glx will clash).

1: Use XRANDR to span the displays (this is what I did previous to the introduction of the third monitor and nvidia card to my system) I tried to do this, by setting up a second X screen on the NVIDIA card, disabling Xinerama; but after much googling I can't figure out the syntax for panning across 2 screens (X screens) in XRANDR, even tho it's >1.3, which supposedly supports multi card output.

2:Use Xinerama, sacrificing randr, and composite extensions. I also attempted to do this, with some limited success. I could get the NVIDIA screen to be right of the ATI, but I couldn't get 2 independent outputs running on the ATI card, even with "ZapohHeads" appended to one of the device sections for my ATI card.

OpenSUSE :: Research On Unabling Composite Effects And Xinerama?

Jun 23, 2011

During my research on enabling composite effects and xinerama, I stumbled upon a few threads and discussions which showed xserver 1.10+ has resolved the conflicts between the 2 modules. I'm wondering if anyone knows of someone/somewhere to get a SUSE compatible build of xserver 1.10+ ? If not, could someone point me toward an easy-to-follow tutorial on how to build packages for SUSE?

Ubuntu :: Improve The Visual Effects To 'extra'?

The hardware devices drivers list three different types of drivers onboard including what appears to be the latest one with accelerated graphics capability. When I try to improve the visual effects to 'extra' it keeps telling me there's an error. I've tried improving the effects with all three but still getting the error.

Sep 28, 2010

Whenever I try to run any of my OpenGL programs with Settings -> Appearance -> Visual Effects: Extra, the program window flickers and disappears. However, if I turn my effects to Normal, my OpenGL programs run smoothly. Any way to have both on at the same time?

Fedora :: Extra Large Fonts In F11 While Running KDE

Jun 13, 2009

Yesterday I upgraded my desktop Hp dx2280 which I use at office and HP Compaq Presario 300 Widescreen laptop which I use at home from fedora 10 to Fedora 11. Upgradation was just fine without any errors in both cases. My desktop machine works just fine and I, hardcore KDE lover, am enjoying working. It is just amazing. But sadly my Presario C300 laptop is a mess for KDE. Login is fine And I got the desktop. First I ran xmms and pleased to hear my favourite mp3 song on it. Sound quality -- EXCELLENT.

But for any other application, whether it is Firefox, openoffice word, kwrite, even the Konsole which I love desperately presents me a screen with extra extra large fonts showing only menus like File Edit & so on. I can not see even fourth menu and no scrollbar etc. Even the clipboard gives me the same result. i.e. extra large fonts. While everything is perfect with GNOME, which I am using now. I am not getting what is the problem. Previously I had upgraded my Presario C300 laptop from KDE 4.1.x from Fedora 11 to KDE 4.2.1 from repo of kdetesting. Is that making some conflicts?

Ubuntu :: How To Install Another Desktop Without Extra Packages

Mar 3, 2011

I want to know how to install KDE on Ubuntu and Gnome on Kubuntu.
The commands
apt-get install ubuntu-desktop
apt-get install kubuntu-desktop
are not the solution, because they install all distro packages, and I want only the base of desktops KDE and Gnome.

I can install LXDE with
apt-get install lxde
instead of
apt-get install lubuntu-desktop

I can install Xfce with
apt-get install xfce4
instead of
apt-get install xubuntu-desktop
However, I could not do the same with KDE and Gnome.

Ubuntu :: Dual Screens: Need Mirror Image Not Extra Desktop?

Sep 8, 2010

I'm using an Intel chipset GMA4500 and Ubuntu 10.04 Gnome. The monitor configuration tool does not seem to have an option to make the secondary screen a mirror image of the primary screen. It works fine when I connect my TV using HDMI as a second screen, but I want it to be a mirror of the primary, because some apps like Skype will only go "full screen" on the primary display.

Ubuntu :: Desktop Still Drawing For Two Monitors After One Is Gone?

Dec 10, 2010

I had a dual monitor setup going for a while, then one monitor broke, and I dropped back down to one. In some ways, the computer seems to have noticed this. I have an NVIDIA card and the NVIDIA drivers, and in NVIDIA X Server Settings it shows only one display. I had it configured in the Xinerama fashion, two continuous desktops side by side.

However, my desktop is still drawn as though there are two monitors, the result being that I can only see half. This is easily apparent when I zoom out to the desktop cube. It wouldn't be much of a serious problem, except for some reason, several important applications I use for work are popping up messages on the part of the desktop that I can't access. I installed the latest NVIDIA drivers,driver reset might prompt whatever the problem is to go away (and it's good to do that regularly anyways) but no dice.

All of a sudden today, the VM started running very slow. I checked the task manager in Windows, nothing eating up PCU or memory there. I then ran htop. Attached is what I saw. There are many repeat processes with different PIDs.
Is this normal?
