PS1: [[BR]]
  Individual users can provide both user and view-only passwords. These should be different. Users can give the view-only password to someone so that they can see the remote session, but not interact.TurboVNC assigns access based on which password is used. The user password lets you provide mouse and keyboard input. [[BR]]

PS2: [[BR]]
  I set 2 passwords for both user & view-only,and passwords are different for all-level users. [[BR]]

PS3: [[BR]]
  Clients should also install turbovnc to run "vncconnect" & "vncview" [[BR]]

=== Step2 Getting DRM & Mesa ===

# DRM kernel module  [[BR]]
The DRM kernel modules are available from the public DRM git repository:  [[BR]]
{{{

=== Step2 Building DRM module & Mesa 3D drivers --- Manual Configuration ===

The DRM (Direct Rendering Manager) provides kernel and library interfaces to clients wanting access to kernel managed resources like interrupts, buffer swaps, DMA memory mapping and graphics memory management.[[BR]]
