Ubuntu :: Composite Extension Is Not Available - Lucid
May 1, 2010
I did a clean install of Ubuntu 10.04 except for the /home partition. I have two monitors. I can't get the setup I had on 9.10 where the second monitor was an extension of the first, and extra visual effects were enabled.
There are two drivers available for my video card, NVIDIA accelerated graphics driver (version 173) and NVIDIA accelerated graphics driver (version current) [Recommended]. I've tried both. I backed up my /etc/X11/xorg.conf, blanked the current one, and run
Code:
I set the each monitor to be a separate X screen, enable Xinerama (I think that's what I need for the extended display), and clicked Save to X Configuration File. Sometimes I merge it with the existing file. At this point I restart and the error, "The Composite extension is not available" is displayed when I try to enable extra visual effects.

Installed Ubuntu 10.10, 64bit, been working flawlessly for a week.
I have 2 nVidia Corporation G96 [GeForce 9400 GT] Graphics Cards and 2 LG Monitors. I installed the nVidia drivers from the website and everything is working very well. Using Xinerama to extend my desktop.
The problem comes in when I add an additional user to the system. It doesn't matter if it's 1 or 2 users, if they are added into the administrator group or as a desktop user, I can delete re-add them, create a completely different user but the problem persists.
As soon as I login as the new user and go to System | Preferences | Appearance | Visual Effects and try and enable either 'Normal' or Extra' I get the following error;
"The Composite Extension is not Available"
This is strange to me because composite, everything, is working fine for the default user, I have no problems whatsoever, but any additional user I setup it seems the graphics is borked, like it's not picking up the correct drivers or something.

After upgrading to 11.2, I get the following error when starting any xclient. Worse, its usually repeated a few times for each client.
Xlib: extension "Generic Event Extension" missing on display <my_ip>
I get this both when using Xming and nomachine.

I have followed a few guides on using video overlays to obtain a watermark. i am suppose to use the Bluescreen video effect along with the composite transition in kdenlive.
I run the following versions of software:
lucid lynx 10.04
FFMPEG compiled from svn
x264 compiled from git
Kdenlive 7.7.1
Kino 1.3.4
melt 0.5.6 from a PPA
Medibuntu repos
My video I want the watermark over is a kino captured file which is dv avi type 2 (open dml).I have done Bluescreen video effect along with the composite transition but the video clip which the video watermark plays on top of ends up getting darker. for the bluescreen color i have chosen red which is the closest red i could pick next to the spinning logo. the lighting changes on it and gives it an undesirable effect as far as how dark it it. i tried other colors but then the logo either disappears or the spinning logos black video background covers up my video. the reason for my "video" watermark is because it is a spinning logo (not a picture) which can be obtained in .mp4 format here:[url]
My goal is to put that on top of some xbox 360 modern warfare 2 gameplay. i haven't uploaded an example of how dark it makes the footage look yet but it does.

My IP has been blocked by Composite Blocking List for " IP Address 207 is listed in the CBL. It appears to be infected with a spam sending trojan or proxy. It was last detected at 2011-01-02 11:00 GMT (+/- 30 minutes), approximately 1 days, 3 hours, 29 minutes ago. It has been relisted following a previous removal at 2010-12-30 17:15 GMT (3 days, 21 hours, 2 minutes ago)"
How do I find this "trojan" and remove it???? I have a network of 6 computers right now, 5 are running Ubuntu (3 server and 2 Desktop versions) and one windows computer. I have run a virus scan in the windows computer and found nothing. How can I scan a linux computer for a virus?

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 am almost tempted to go back to an old slackware to try this. Anyway, I found a circuit (with just a few resistors) that allows vga output to go to composite input. To my amazement it actually works and it is very clear, but has a double screen. I am told, to fix it you need to change the horizontal sync and or refresh rate for the card. (17 instead of 35). How would I do this in xorg.conf?

I have four smaller jpg files, that I would like to merge into one file. Each image is similar in size, and they are color images. The only way I could get close is by creating multi-layered composites, which got really big. The only other way I could think of doing it is with OO, creating a presentation slide, and then rendering that slide.

I have a render script that uses several Blender 3D instances on several machines to co-render one still image. The image is split into squares of 64 x 64 pixels. In the end, I have like 200 image files, each one with a puzzle piece of the whole.
Now I would like to assembe these pieces into whole with PIL and Python, but so far cannot figure out how. I am new to PIL, but in imagemagick, a convert image1.png image2.png image3.png +append finalimage.png works a charme. But convert chokes on so many image files, so I need something automatic and scalable. I think that pictures are RGBA, so black should be the alpha channel and transparent.
I think I have to mention that the pieces are in the right position and that every piece has the original dimensions of the full picture, so it is not a problem figuring out where each piece should be. Just putting all the pictures on top of eachother and ignoring anything that is black would do the trick nicely.
How can I reach this with PIL? Which functions do I need for that? PIL does a lot of stuff, so finding my simple function is daunting.

I just installed Fedora 13 and though I'd give kde4.4 a try and see how it is. So far I'm liking it however I've got a couple problems with kde.
First off, I cant enable desktop effects (I don't seem to be only one with the problem, though I havn't found a fix yet).
Secondly, when I mouse-over an item on the panel, a piece of a window on the opposite side of the screen from the panel 'vanishes'. This isn't very easy to explain so I've attached a screenshot. My mouse is over the clock on the top right. I had this bug on an earlier version of kde4 some time ago, hoped it was fixed .
The nvidia drivers are installed (from rpmfusion), working (I can play games and glxinfo reports direct rendering etc) and don't throw any errors - the composite extension is loaded.

Below are some system specs and details:
Vid: GeForce GTX 260M
Kernel: 2.6.33.5-124.fc13.x86_64
Kernel module:
lsmod | grep nvidia
nvidia 10823576 30
i2c_core 24507 2 videodev,nvidia
I've also attached the Xorg log and the xorg.conf file.

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?

Since I have upgraded to KDE 4.5 I can't play games (native or wine) without disabling composite before start playing.When I start a game its window begins to shiver (to tremble or to shake... not sure) and so I have to disable composite first and then relaunch the game.I never had to do this in KDE 4.4.

I would like to know if anyone has built a system with a video card that provides a composite video output. Which Linux distro and video card are you using that allows for composite (YES composite) video output from a video card?
I am looking for specific answers here because I don't want to reinvent the wheel if its been done before or waste, money and time.

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).

I recently upgraded from Karmic to Lucid via the Update Manager. I would like to upgrade further by switching from 32 Bit to 64 Bit. I downloaded the Lucid 64 Bit ISO and wrote an install disk. When I reboot the computer with the install disk nothing happens.

Just made the upgrade to 10.04 and after copying my /home/ directory to my external and back over to my hard drive, the .mp3 extensions have all disappeared. Dolphin still identifies the files as mp3 audio files, but without the extension, Amarok, Banshee or VLC will not play them. Is there anyway to get the media players to play those files, or anyway to add the .mp3 extension onto all of those files at once?

I installed Minecraft and I want to hide the .JAR extension on the file on my desktop. I tried just renaming it and deleting the ".jar" from the name, but when I tried opening it, it opened as an archive, rather than an executable, even though I had the "Allow executing file as program." box checked off. What can I do to hide the extension?
