visual effects on Ubuntu 10.04?

Just installed Ubuntu 10.04 in a Parallels 5 VM. It works well overall, but when I try to enable Visual Effects (and after it does a search for drivers) I get the error, "Desktop effects could not be enabled."

I'm guessing this is an issue with the Parallels display driver? Is there another driver I could install that would work, or some other fix?

Thanks!
 
schvenk,

Ubuntu 10.04 beta 1 places libGL.so* to /usr/lib/mesa/ and configures dynamic loader so that it takes precedence over more conventional /usr/lib/libGL.so*.
The simplest solution is to edit /etc/ld.so.conf putting /usr/lib on the first line, and then run ldconfig to rebuild loader cache.
 
Thanks for the help. I changed /usr/lib/mesa to /usr/lib in /etc/ld.so.conf/GL.conf and am now able to enable visual effects...mostly. Transparency works, wacky window drag effects work, but I don't get any drop shadows. Any thoughts?
 
I too want to make Desktop Effects enabled, but am a bit confused as to how to edit ld.so.conf. Here are the contents of it:

include /etc/ld.so.conf.d/*.conf

How would I edit this so that Desktop Effects will work? This seems to be different from the file as described in previous posts. Thanks.
 
Hi, you should edit the file: /etc/ld.so.conf.d/GL.conf
Code: 
sudo gedit /etc/ld.so.conf.d/GL.conf

You can delete (or comment) the original lines and add:
Code: 
/usr/lib

Spoke too soon

Sorry, I spoke too soon - I hadn't run the ldconfig command. Having done this, visual effects not only works, but so does the mouse component of Parallels Tools. Excellent!
 
Hi

I am trying to learn more about linux and I was just wondering how you run the ldconfig command. I have found a few ways to try by searching but none of them work for me.
 
Hi Adam,

Open the terminal (from menu: Applications > Accessories > Terminal)

Type:
sudo ldconfig

Enter the super user password (normally it's the same as your) - sudo allows you to execute a command as the superuser.
 
Visual effects.

I am also having the exact same problem and I am trying to fix it using the suggestions Ive read on here. I put in idconfig in the terminal and got this /sbin/ldconfig.real: Can't create temporary cache file /etc/ld.so.cache~: Permission denied What should I do?
 
@Bradrox: ldconfig shouldn't print any message. If you want to see the output, run:
Code: 
sudo ldconfig -v

Didn't it work for you? Can you enable visual effects?
