FontPath "tcp/ServerIP_Address:7100"
## Client can get fonts support from x font server (xfs)
xrdb Bug Fixed:
Bug1:
## Put the RGB Database (rgb.txt - attached file)to the path /usr/X11R6/lib/X11/
rock@gpfs-server:~$ sudo cp /home/rock/rgb.txt /usr/X11R6/lib/X11/
Bug2:
## Adding an empty file named: .Xresources at PATH:///home/rock to fix " xrdb: can't open file '/home/rock/.Xresources' "
Part3 - TurboVNC Server Activation
@Server
rock@gpfs-server:~$ /opt/TurboVNC/bin/vncserver
New 'X' desktop is gpfs-server:1 Creating default startup script /home/rock/.vnc/xstartup Starting applications specified in /home/rock/.vnc/xstartup Log file is /home/rock/.vnc/gpfs-server:1.log
@Client
rider@350z:~$ /opt/TurboVNC/bin/vncconnect [-display Xvnc-display] ServerIP[:port]
rider@350z:~$ /opt/TurboVNC/bin/vncviewer [Enter ServerIP & Passwd]
PS1:
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.
PS2:
I set 2 passwords for both user & view-only,and passwords are different for all-level users.
PS3:
Clients should also install turbovnc to run "vncconnect" & "vncview"
VirtualGL
Mesa 3D GL Driver
Step1 System Check
#Pre-Requirement
rock@gpfs-server:~$ sudo apt-get install mesa-utils libgl1-mesa-dev libgl1-mesa-dri libgl1-mesa-glx libdrm-dev libdrm2
rock@gpfs-server:~$ lsmod | grep drm
drm 73748 3 i915 agpgart 30408 3 drm,intel_agp
rock@gpfs-server:~$ dmesg | grep drm
[drm] Initialized drm 1.1.0 20060810 [drm] Initialized i915 1.6.0 20060119 on minor 0
rock@gpfs-server:~/intel_Q965/mesa$ dmesg | grep agp
Linux agpgart interface v0.101 (c) Dave Jones agpgart: Detected an Intel 965Q Chipset. agpgart: Unknown page table size, assuming 512KB agpgart: Detected 7676K stolen memory. agpgart: AGP aperture is 256M @ 0xe0000000
PS1: Some of the DRM messages should like that! If DRM module can't be found, then you can try to do something below.
rock@gpfs-server:~$ sudo modprobe i810
rock@gpfs-server:~$ sudo modprobe drm
PS2: You can skip "Building DRM module" when your DRM works well.
Caution:
You can also make related kernel modules (mark as module) below without building DRM & Mesa Driver. The latest Mesa 3D driver needs at least libdrm 3.5.0, and 2.6.20 kernel may not support very well for some missing symbols.

Step2 Getting DRM & Mesa
rock@gpfs-server:~/intel_Q965$ sudo apt-get install git git-core cogito
# DRM kernel module
The DRM kernel modules are available from the public DRM git repository:
rock@gpfs-server:~/intel_Q965$ git-clone git://anongit.freedesktop.org/git/mesa/drm
# Mesa 3D GL driver
The GL drivers are available from the public Mesa git repository:
rock@gpfs-server:~/intel_Q965$ git-clone git://anongit.freedesktop.org/git/mesa/mesa
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.
