I have installed Ubuntu 11.10 as virtual machine within Mac.
I have installed VM tools.
The approach in this link of Compizconfig Grid, which worked in my previous laptop where Ubuntu was not a virtual machine, does not work anymore. I set some shortcut, but no action is launched...
Does anyone know why?
The major functionality I need from Grid is tiling windows to left/right side of the screen... Does anyone know any alternative?
PS: I have tried other plugins of Compizconfig, for instance, Move Window works...
Edit1: The desktop environment I am using is Ubuntu, not Gnome. The unity is 2D instead of 3D. It is not a problem for me to change it if that can solve the Grid or tiling problem above.
Edit2 & 3: I didn't know that Unity2D does not use compiz by default... After installing gtk2-engines-pixbuf, I launched compiz --replace &in a terminal, that gives:
And I tried Grid once again: bind shortcut <Control><Alt>g to Put Left, it still does not work.
But as I said before, if I bind <Control><Alt>g to Initiate Window Move in Move Window (either before or after compiz --replace &), the shortcut always has an effect...
Edit 4: I just enabled Accelerate 3D Graphics, which was disabled before... But rerunning compiz --replace & in a terminal gives exactly same message as before including 2 Fatal for opengl.
As I get it, *Fatal: GLX_EXT_texture_from_pixmap* means that X server does not support *GLX_EXT_texture_from_pixmap* API feature, which requires a 3D hardware acceleration.
You can see the previous error message: Fatal: Software rendering detected which means that VM has no configured 3D graphics acceleratio card, either because there is no such hardware in your system, or it's not properly configured.
So check out if there is 3D acc. card in the host OS, or not. If there isn't I guess you can't make Grid work. If there is, you should configure your VM to expose 3D acc. card to the guest ubuntu OS.
