Is there any Virtual Machine for mac that supports 3D acceleration?

Q. I want to have Visual Effects enabled on my Linux Virtual Machine (Ubuntu).


Good answer gets 5 stars!

A. No. There currently aren't any virtualiziers on the market which can emulate OpenGL. VMWare Fusion is able to emulate Direct3d for windows virtual machines, but it doesn't have support for the OpenGL renderer needed by compositing window managers in Linux.

How do I change the command line prompt to show just the login id.?
Q. This is on a linux virtual machine?

A. The easiest way to do it for all users is to edit the file /etc/profile.

There should be some lines in that file for setting PS1, which is the primary shell prompt. You can edit or add lines like this:

PS1='\u@\h:\$ '
export PS1

This will make the default prompt this, with a space after the dollar sign:

user@hostname $

How do I create user accounts using a script that reads a list of names from a file?
Q. It creates user accounts for each name. This is on a linux virtual machine.

A. You'll have to write a shell script that reads the names and information from the file one line at a time, then pipes it to a tool like adduser, which will then add the user information to the appropriate system files. This has to be done as root or with admin privileges.
