Compiz problem

[arcelivez]

OK, this problem has really pissed me, I wanted to make a mac style dock, but I can´t because the Avant Window Navigator doesn´t start because it says ¨screen isn´t composited¨ and about the compiz stuff, I can´t even enable the desktop effects, because it says ¨Desktop effects could not be enabled¨, and I can´t run the compizconfig settings manager, it´s starting, but all it does is at the beginning an item notifies that it is starting but then it disappears without saying anything and doesn´t get turned on. I´ve read plenty of threads regarding this issue, but none of them have helped me. So I am counting on you guys, since I´m really not keen on reinstalling the whole system. Besides I´m a noob in Linux. So i´ve downloaded the compiz-check and this is what I get:



arturas@whatever:~$ ./compiz-check

Thanks in advance. I am using the nVidia geforce 9200M GS on my laptop by the way, oh and my version of ubuntu is installed with wubi.

Have you installed your video driver through system>admin>hardware drivers?

[arcelivez]

Yes. Any tips? :/

Try turning on Metacity's compositing and see if AWN will run under that. In a Terminal (Applications > Accessories > Terminal) run the following.


gconftool-2 -s '/apps/metacity/general/compositing_manager' --type bool true

I dont know if this bug is still around but it used to be that you had to turn off Metacity's compositing before you started Compiz (Desktop Effects).


gconftool-2 -s '/apps/metacity/general/compositing_manager' --type bool false

let us know how this goes,

Thanks, great, now the dock avant window navigator works!

Well most of it, because when I try to run it's dock preferences they won't start, so I'll have to find a way to do that. The visual effect extras don't work either, but they aren't really important to me I guess.

Thanks very much again! And if someone knows how to solve the awn preferences problem I'd be grateful if they shared that.

If I try to access them over terminal this is what I get:


arturas@whatever:~$ awn-settings

My solution was to turn on visual effects. This initialized Compiz Config Settings Manager in some way..subsequently, it ran as intended.
