Problem with compiz-fusion in ubuntu 9.10

jeremy28 · 03-18-2010, 06:46 AM

Hi all

I'm using ubuntu 9.10;

I wanna add "compiz-fusion" effects to it, but I've not arrived yet!

I decided to "Complete-Remove" all packages related to "compiz" in synaptic and then installed all of them again
such the below image:
http://www.theimghost.com/view/720Screenshot_2.jpg

But now I can't select the Extra or Custom option in the "System> Appearance> Visual effects" part and I face this
message:
http://www.theimghost.com/view/4441.jpg

I think this is because once I removed "completely" the related component, so the appropriate driver isn't found!

Is there any way to solve this problem?

Which files has my system lost?

I searched the ubuntu help and couldn't find the correct answer!

Please help me...

Regards.

Why did you do that? Uninstalling and reinstalling all compiz packages almost certainly was not necessary.

See this tutorial:
http://www.ubuntugeek.com/how-to-ins...-10karmic.html
Make sure you have the 3D driver installed for your graphics card as directed on that page.
Make sure you have installed all of the packages listed under "Install CCSM on Ubuntu" on that page.
After installing them as directed, you can check that they are all installed by opening a terminal and running:

Code:

aptitude search compiz

This will output a list of packages. A "p" before a package means it is not installed. A "i" before a package means it is installed.

Also make sure you have 3D enabled. In the terminal run:

Code:

glxinfo | grep -i direct

It should output "direct rendering: Yes". What graphics card do you have?
Here is another tutorial on compiz:

Hope this helps.

Hello and thanks of your help!

I run "aptitude search compiz" command and the result was as below:

Code:

My Graphics Card is "Intel GMA 950";

I've run "sudo apt-get install xserver-xorg-video-intel" in terminal to install the related drivers and the result was as below:

Code:

Reading package lists... Done
Building dependency tree       
Reading state information... Done
xserver-xorg-video-intel is already the newest version.
The following packages were automatically installed and are no longer required:
  libalut0 libhildon-1-0
Use 'apt-get autoremove' to remove them.
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

But the problem isn't resolved yet!

What's the solution?

I think the problem is because I currently don't have 3D enabled drivers!

How and where should I install my appropriate drivers from?

Help me please...
Thanks in advance.

adamk75 · 03-19-2010, 06:41 AM

The drivers would have been installed by default in Ubuntu, so you broke something along the way. Please show us your /var/log/Xorg.0.log file.

As Adam said, the xserver-xorg-video-intel driver is part of a default Ubuntu install; so you already have that driver running. That is why you got:
"0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded."
when you installed the intel driver from the terminal using apt-get.
You should not be uninstalling and reinstalling stuff unless you have a valid reason to do so.
The 3D for your intel video should have been enabled by default in Ubuntu, as long as 3D is supported for your card by the intel driver. The intel 945GM on my laptop has "direct rendering" enabled by default in Ubuntu 9.10.
Follow Adam's advice and have a look at /var/log/Xorg.0.log file.
Also post the output of:

Code:

less /var/log/Xorg.0.log | grep EE

This will list any errors from the Xorg log. Also post your /etc/X11/xorg.conf file if you have one. You may not have a xorg.conf file though, since current versions of Xorg don't even need one.

One other request;

As you mentained, the driver is installed by default in ubuntu, now I've removed it, but it should be in my system and I should be able to install it again by synaptic!
Am I right?

If so, how should I find the driver in synaptic?
Which keywords should I enter in search box of synaptic to find the mentained driver?

Kind Regards.

adamk75 · 03-20-2010, 09:02 AM

You have the nvidia driver installed, yet you're using an intel GPU. You need to competely purge the the nvidia driver from your system (remove anything with 'nvidia' in the name in synaptic) and then reinstall libgl1-mesa-glx and libgl1-mesa-dri

tommcd · 03-20-2010, 09:04 AM

Here is your problem, as reported in your Xorg.0.log:

Code:

(II) LoadModule: "i810"
(WW) Warning, couldn't open module i810

You are using the vesa driver, instead of the intel driver.

You must have screwed something up then. Now if we can just figure out what it is.

What is the output of:

Code:

aptitude search xserver-xorg-video-intel

If there is an "i" before the intel driver package in the output, then you have it installed. (You may also see an "A" after the "i". The "A" means automatically installed).
In your last post you said you ran:

Code:

sudo apt-get install xserver-xorg-video-intel

and this was part of the output:

Code:

xserver-xorg-video-intel is already the newest version.

So you already have the driver installed.
I am not sure why you are using the vesa driver. On my laptop, I am running the intel_agp and i915 modules. If you run the command lsmod (list modules) do you see those in the output? What happens if you run:

Code:

sudo modprobe i915
sudo modprobe intel_agp

This should load those modules, if they are not already running.

Try this:
Boot to recovery mode and choose the option "xfix fix video (or whatever it says exactly). Run through that and then reboot. Then run "glxinfo | grep -i direct" again, and see if you get a "yes".
I am not sure if this will fix things or not, but it should not hurt anything.

You are using the vesa driver, instead of the intel driver.

This is not true as witnessed by all the lines that start with:

Code:

(II) intel(0):

Xorg loads the vesa driver in case it can't find and attach the intel driver, which it clearly does.

How do you know from that output that the intel driver is actually loading? I am not doubting you, I am just trying to figure this problem out. The reason I ask is because I do not see anything about loading the vesa driver in my Xorg.0.log, as Jeremy does.
Also, do you have any idea why Jeremy28 does not have direct rendering enabled?

I said why he doesn't have direct rendering above. He has the nvidia drivers installed and he's loading the nvidia glx module.

As for how I know that the intel driver is loading... It's those lines that start with "(II) intel(0):" as I said. That's from the intel driver. Do you have an xorg.conf file? If so, that's undoubtedly why you aren't loading the vesa driver as Jeremy28 is.

Hi and thanks for your helps!
My problem resolved.

First, I removed (not completely of course

) nvidia packages in synaptic and reinstalled libgl1-mesa-glx and libgl1-mesa-dri;

But after running "glxinfo | grep -i direct" command, I didn't see the response "direct rendering:yes" again!

I think it would need a system restart to take effect!

Then I tried to boot to recovery mode;

What is the output of:
Code:

aptitude search xserver-xorg-video-intel

The output was:

Code:

~$ aptitude search xserver-xorg-video-intel
i   xserver-xorg-video-intel        - X.Org X server -- Intel i8xx, i9xx display
p   xserver-xorg-video-intel-dbg    - X.Org X server -- Intel i8xx, i9xx display

Then, I installed "xserver-xorg-video-intel-dbg" by synaptic.

If you run the command lsmod (list modules) do you see those in the output?

Yes, I see:

Code:

intel_agp              27676  2 i915
i915                  226120  2

I got recovery mode, but I didn't see "xfix fix video" option or something like it, I just selected the "dpgk..." option from menu to repair and then reboot the system and saw the result "direct rendering:yes" in terminal!

Indeed, I don't exactly know which action solved my problem ?!!!

Anyway, Thanks so much for your guides.

Have fun.
