I solved the problem

I had the nvidia driver installed, but I had to adjust couple of thing on xorg.conf

1. Comment the line wich loads the Dri module on Section “Module”
2. Add Option “RenderAccel” “true on the Device Section
3. set to “24″ the default depth on the Section Screen

This last one was decisive. I didnt test it without the modifications 1 and 2. But its necessary to have the default depth set to 24 in order work! And now its just fine!! beautiful!

till now I had only one crash, an one window that became incative (B&W) and never woke up again. but Im using just fine

thanks for the help

cheers

Leo,,

Even before I run starcompiz, the screen is laggy. Simply drawing a selection box on the desktop will cause some strange color effects. The windows wont refresh on the screen properly, and if I click on a icon on the launch bar the Session crashes.

did you install the proprietary nvidia drivers? that should vastly improve your performance if you haven’t. it’s easy to do, just open a terminal and

sudo apt-get install nvidia-glx

and then edit your xorg.conf

sudo gedit /etc/X11/xorg.conf

and find the line

Driver "nv"

and change it to

Driver "nvidia"

then save the file, close it and restart X with ctrl+alt+backspace.

if that isn’t the problem or doesn’t seem to fix it, head over to compiz.net and ask around there.

After some struggle I managed to get it (almost) working.

I start compiz and it works just fine. But with all the problems I metioned above… It seems that its a problem of refreshing the screen/ rendering … as if I havent got enough memmory for that…

but Im running an AMD64 (running a 32bit system though), 1Gb Ram, nvidia vide card with 64M…

any clues?

Leo,,

I get this error message after i try to login saying that the session only lasted 10 seconds, and i have to change to gnome again to login. any ideas?

i think this behavior is typical of ati video cards. i remember there was a way to set the session timeout to be longer to accomodate those drivers, but i can’t recall what it was. look around over at compiz.net for more information.

I should ask there so.

Thaanks again!
