View Full Version : [ubuntu] Screen Is Not Composited

March 28th, 2009, 10:59 AM
Hey Everyone,

How can i solve the error message "Error: Screen Isn't composited. Please Run compiz (-fusion) or other compositioning manager"

I am using a Dell GX240 and am unsure what this error means,

when do you get that error? sounds like a compatibility problem with compiz if you turn off the visual effects does it still appear?

I am trying to get the Avant Window Manager to load, i have been configuring the Mac4Lin package and this error appears as soon as the computer starts

what gfx card do you have?

Do you know how you find this out? I think it is onboard to be honest.

i think u also need to enable compiz:
System -> Preferences -> Appearance
click the Visual effects tab
choose normal or extra

you could also install the package simple-ccsm

lspci | grep VGA

maybe that returns your vid card

i have installed that now using sudo aptitude install simple-ccsm

Also when i check any options under visual effects i get the message 'Desktop Effects Could Not Be Enabled'

Maybe Reboot?

yah, you need to find out what gfx card you have. i think it has to be 3d accelerated in order to use compiz

did the lspci cmd return anything?

if not, you could try to run lspci and look for anything regarding your video controller

is there any drivers in System -> Administration -> Hardware drivers

or else we need to find a driver for your gfx on the ati hp... should be there somewhere just haven't found it yet. but i'll keep looking

I did look their last night when i first got the issue, that pane is empty. Their are no drivers at all in their.

hmm i'm quite sure that the video card driver is the problem. still searching for a driver for you... haven't had any luck yet tho..

try this:

gedit /etc/X11/xorg.conf

find the section device and write it in here. I'd like to know if the driver xorg is using is ati or r128
