I just upgraded my Linux guest running on Win7-64 VirtualBox 3.2.10 from Ubuntu 10.04 to 10.10. I followed the usual steps to reapply guest additions, including installing build-essential and linux-headers-... before running the guest additions installer. No errors or warnings occurred in the installer, which output messages indicating that it was using all the X11 stuff, and I restarted the guest. I also checked that 3D acceleration is on.

Despite everything seeming to go quite smoothly, I am no longer able to turn on Extra effects in System|Preferences|Appearance|Visual Effects. It was working a treat with 10.04. When I click the button, it spends about 15 seconds searching for available drivers, flickers everything, grays out the dialog box for another five seconds or so, then finally pops up a dialog box that says, "Desktop effects could not be enabled". The same thing happens when I click "Normal" or "Custom" (except that the driver search only happens the first time I click any of these options).

UPDATE: I get the same output, and the same outcome, if I run the installation script as root.

Why can't I turn on Extra Visual Effects after upgrading to Ubuntu 10.10?

Tried restarting the VM ? –  Sathya Oct 27 '10 at 2:55
    
@Sathya: Yes, I did; several times, in fact. –  Marcelo Cantos Oct 27 '10 at 2:57
    
That's .. odd. Try removing guest-additions from Ubuntu Software centre, just to be sure. –  Sathya Oct 27 '10 at 4:31
    
...or re-installing the guest-additions. –  Boldewyn Oct 27 '10 at 10:00
    
The guest-additions from Software Center haven't been loaded, AFAICT, and I've tried reinstalling them several times now. I haven't tried uninstalling the version installed by VBox because a) I don't know how, and b) it seems that the installer does that anyway. There isn't much on this VM that I need to keep, so unless someone is keen to get to the bottom of it, I will probably just do a reinstall from scratch in the (Australian) morning. –  Marcelo Cantos Oct 27 '10 at 10:08

Try installing dkms as well:

sudo apt-get install dkms

build-essentialis needed as well most likely, but you said you already had that installed.

Dkms did the trick. I had to reinstall the guest additions after installing dkms and then reboot the guest, but I now have lovely wobbly windows. Woo-hoo! –  Marcelo Cantos Nov 10 '10 at 0:06

I had this problem.

Make sure you have all 128MB assigned to graphics, and make sure VT-X, ACPI etc are all switched on, I had to reinstall the additions a couple of times before it worked.

Thanks for the suggestion. I did have it set too low, but adjusting it made no difference. –  Marcelo Cantos Nov 10 '10 at 0:05

@gencha omg, I was just running into the same exact problem as the OP. At first I thought I was doing something wrong since this is my first time trying out VirtualBox. My setup is almost the same as his, host is Win7 64-bit, guest is Ubuntu10.10 64-bit. I've followed the instructions found around the web to the letter and couldn't get it to work.

I tried gencha's suggestion and went ahead downloaded dkms. Reinstalled the Guest Addition, and a restart later boom! it works! And here I was spending hours cursing this stupid thing wondering why it doesn't just work.

I would upvote you gencha but it's a bit difficult since I don't have 15 rep on this site yet :(
