Server :: Error - Xlib: Extension "XINERAMA" Missing On Display ":0.0"
May 26, 2010
I am trying to get xinerama to work with x11vnc on Xvfb and I am getting:
xdpyinfo -ext XINERAMA
Xlib: extension "XINERAMA" missing on display ":0.0".
XINERAMA extension not supported by server
I am using the latest version of x11vnc which says XINERAMA is on by default. I have tried xf4vnc as well and get the same issue.
Xvfb :1 -screen 0 1024x2048x24 &
mwm &
x11vnc -display :1 -bg -nopw -xkb -N
I get a screen that looks like xinerama and windows pass from display to display fine, however xdpyinfo says otherwise and we have software that looks to xdpyinfo to get information about how display guis. When x11vnc was compiled it said it found libXinerama. Not sure what is going on. Does vncviewer need to support xinerama as well? Is there any way to tell if vncviewer does without downloading a newer or different version?

I am trying to run the SDK for Meego with Qt. When I try to launch my simulator I get the error message: Xlib: extension "GLX" missing on display ":0.0". The answer I got on Meego's forum is that I am missing glx extensions. I have tried to find a way to get the glx extensions but I do not seem to get it. My searches on the web all point to Nvidia, but I have got ATI. I run Lenny 5.0.6 amd64.

I've verified that xorg-x11-libs is installed. This package provides libXrandr.so.2. However, when I run a program, in this case the python script for blueproximity (start_proximity.sh), I get the error in the title.
Code:
grep -ni randr /var/log/Xorg.0.log

I'm trying to build a program called Obpager, but I'm getting an error saying I don't have xlib.h. From what I understand, that file is included in libx11-dev, which I have installed. Any idea?

I am having trouble writing an Xlib application that displays a window. The most frustrating thing is that I've written applications like this before, and never had any problems. For some reason I cannot get this program to work properly. I'm running KDE and when I launch the program, a "button" for the application will appear on the application panel, however, no window will display. It is possible to right click on the panel button and select the Close item which will successfully close the window.
The following is source code that when built will exhibit the behaviour described above code...

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.

I'm having a problem with connecting over ssh to a server (wrdsvr) that has me perplexed. I'm using putty to connect from my WIndows VM desktop to a SLES 9 server. If I connect to wrdsvr from my desktop over ssh and run certain commands with multi-line output, the display freezes after the first line. If I connect from my desktop to a different server (oksvr), and then from oksvr I connect to wrdsvr, then there is no problem. In fact, by running 'w' after connecting in that roundabout way I can see that subsequent commands I type into the frozen window still run.
I just can't see anything in the window itself as the display is frozen. I have sshd logging running in debug mode on wrdsvr and there is nothing produced during this. There is also nothing in the putty event log. If I type 'exit' in the frozen window, the server sees the connection as closing normally and then gone. Usually my putty window would then close automatically, but in this frozen case it doesn't. So although it is sending characters I type in, it doesn't seem to be receiving the output in return.
commands that run successfully are:
w
ls
man
less
commands that cause the display to freeze are:
ps ax
ls -l
top (for this one I don't even get the first line of output, it freezes immediately)
The machine I'm connecting from is a VMFusion guest running Windows XP. I get this behavior connecting using putty, but I also installed a demo version of securecrt (when this issue occurred previously) which saw the same problem, but I can't repeat it as my license expired. (Last time the issue went away while I was troubleshooting an immediate service-affecting problem on that and a number of other servers and I don't know what fixed it!) I exported the putty registry keys and the profiles for the two servers are identical. I tried loading the profile for oksvr and temporarily changing the hostname to wrdsvr, but saw the same issue. I am connecting over a Cisco VPN.
My colleague is on the local network and does not see this issue when he connects to wrdsvr using putty. We are both using the same version of putty 0.60. Here is the background on the servers. Both wrdsvr and oksvr are running SLES 9. My actions just before I noticed these issues were the following. I updated them using you (yast online update) to the latest patch versions. Using the rpms from Novell, I installed binutils, make, gcc, and glibc-devel and finally VMware tools on both. I then rebooted. Since then I've run you again but that hasn't changed anything. I've compare the installed patches using diff and they are the same. Now I'm working my way through the output of rpm -qVa on each one, but nothing so far.

I have an ATI Radeon HD 3300 on-board video chipset, and an ATI Radeon HD 4350 PCI card. What I want is to have both displays available from one mouse/keyboard. I want to play media on one and have the other as my main desktop.The problem is that with Xinerama enabled, KDE desktop effects do not work (KDE says XComposite and XDamage are not available, even though I explicitly enabled them as extensions in the xorg.conf file), and performance is quite bad. Without Xinerama enabled, performance is great, desktop effects work great, but there's a lot of trouble with full-screen video, and the KWin window manager does not apply in the second display (although I can run a second instance of KWin on :0.1).

According to the Wiki about Xinerama
Quote:
As of the 1.10 X server release, the Xinerama rendering multiplexer and Composite extensions no longer conflict.[URL].. So does this mean that if I use X 1.10 or later, Xinerama and composting can work even over two GPUs and four monitors?

I've just upgraded (finally) to 10.04 desktop, and when I boot, I get a login screen, which is quite usual, but once I log in, the machine drops to terminal, instead of the usual GUI. I've tried running startx, but I get this error message. Fatal server error: Server is already active for display 0 If this server is no longer running, remove /tmp/.X0-lock and start again.

I am currently trying out Debian in VMware Player and I installed it using the following method.
Image Used: Debian-7.6.0-amd64-netinst
In the check list where it lets you select Debian Desktop, Print Server, and System Utilities I think it was? I deselected everything.
After Debian installed and rebooted I logged in, elevated myself to su, and entered the following commands.
apt-get update
apt-get install kdm kde-plasma-desktop --no-install-recommends
reboot
startkde
and I get the error '$DISPLAY is not set or cannot connect to the X server.'

I have a fresh install of OpenSUSE 11.4 64bit and I have installed the AMD Display drivers for my Radeon HD 5970. Everything seems to be working quite well. I have a multiple monitor setup (1280x1024 monitor and a 1920x1080 monitor).
I have my primary display set to 1920x1080, however when I try to enable the second display, I get a CRTC error that the display is over the maximum (1920x1920). If I enable both monitors at lower resolutions, there is no problem.
I have done a fair bit of reading and have been unable to determine where this maximum is set, or how to change it. I'd like to be able to run both monitors at their native resolutions.

I have the following scenario that doesn't seem to work normally. I have a windows 7 pc from which I am using putty to connect to my other linux servers (all running redhat 5 and 6). So here is the scenario that works and one that does not work. And I'm trying to figure out the one that does not work. Scenario that works:
From windows 7 (putty) I ssh into Linux_Server_1.
echo $DISPLAY
localhost:10.0
I run xclock and I see it pop up on my windows 7 pc. I am using xming on windows 7 to help me populate the display from linux to windows. One that does not work:
From windows 7 (putty) I ssh into Linux_Server_1. Then from Linux_Server_1 I ssh into Linux_Server_2.
echo $DISPLAY
<no output>
I try to setup $DISPLAY with localhost:10.0 or 0.0 or even my windows 7 pc ip address:0.0 ....etc Then when I try to run xclock I doesn't work.
I get these error messages: Error: Can't open display: <ip of display>
Also as a side note all our Linux servers are sitting on one subnet. My pc is sitting on another subnet. I use vpn to connect to the subnet where the servers sit from my pc.

I have lot of problems installing red5 video server, on my VPS.First things first, here is the specs of my VPS:
OS: CENTOS 5.4 i686 virtuozzo on server
Administration: cPanel 11.25.0-S43473 - WHM 11.25.0 - X 3.9
Mysql: 5.0.89-community
PHP: 5.2.10
Apache 2.2.11
Saying that, I will try to explain my problem as detailed as possible:I try to install red5 video server, following the tutorials and guides to do that, but there are some prerequisites to fulfill before installing the program:
Prerequisite No.1.: Having the latest version of Apache ANT.
Prerequisite No.2: Having the latest Java devel version.
The server already got the Apache ANT 1.6, but red5 asks for 1.8 The server already got java 1.5 but red5 asks for 1.6 So, I try to update to ANT 1.8 and Java 1.6, but refuses to update, so I made a clean installation of both, doing this:[URL]
JAVA:
# yum -y install java-1.6.0-openjdk java-1.6.0-openjdk-devel
Then I install Apache ANT doing this:
# cd /usr/src
# wget http://opensource.become.com/apache/...8.0-bin.tar.gz
# tar zxvf apache-ant-1.8.0-bin.tar.gz
# mv apache-ant-1.8.0 /usr/local/ant
[code]....
Then, when I execute the command: ant -version to find out which version is running, I get more errors:
root@server [~]# ant -version
/usr/bin/build-classpath: error: Could not find xml-commons-apis Java extension for this JVM
/usr/bin/build-classpath: error: Some specified jars were not found
[code]...
Also, the VPS is not resolving the domains properly, prior to this, the domains were fine, but after that, I need to do a gracefull reboot, and then restart the named service.
1.- How can I undo all the things I did, I mean, is it a way to uninstall the APACHE ANT 1.6.5 and then the 1.8 and Java 1.6, and then start from the beginning?
2.- After uninstalling these 3 apps, I need to reinstall it properly, and make red5 work on the server, so, how can I do it safely?
A mistake I did, was to not to backup the server prior to make the changes, and is a production VPS on a shared server with the vpsnext.com hosting provider.I speak with the technical support, and they are not be able to help me, because is an unmanaged server.
One more strange thing is that, I already install red5, with ANT and JAVA in another server, with the same specs of this VPS, from another hosting provider, and I had no problems at all.
