Installing the Graphics Agent for Linux on RHEL or CentOS

Important: Required ports will be automatically opened

The Graphics Agent for Linux installer will add firewall exceptions for the following required PCoIP ports during installation: TCP 443, TCP 4172, UDP 4172, and TCP 60443.

Teradici has a new repository distribution system

Teradici is moving to a new repository distribution system, and the URLs which fetch repo upgrades is changing. If you are upgrading an existing installation which uses the downloads.teradici.com subdomain, delete the existing repo from your machine's configuration, then use the configuration script provided here to install the new one.

The old system is deprecated and will be removed in the near future.

To install the PCoIP Graphics Agent for Linux software:

  1. Download and install the Teradici pcoip-agent repository, via the shell script provided here.

    An account is required to download

    A Teradici account is required to access this repository. You can create one from the login screen if you do not already have one.

  2. Install wget:

    sudo yum install wget
    
  3. Install the EPEL repository:

    sudo wget https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
    sudo rpm -i epel-release-latest-7.noarch.rpm
    
  4. Optionally install USB dependencies, if you intend to support USB devices other than keyboards, mice, and pointer devices. If you skip this step, USB redirection will be completely disabled and bridged USB devices will not work.

    sudo yum install usb-vhci
    
  5. Install the PCoIP Graphics Agent for Linux:

    sudo yum install pcoip-agent-graphics
    
  6. Note your machine's local IP address. Clients connecting directly to the host workstation will need this number to connect.

  7. Enter the license registration code you received from Teradici.

    Note: These instructions are for Cloud Licensing

    These instructions assume you are using Teradici Cloud Licensing to activate your PCoIP session licenses. If you are using the Teradici License Server instead, see Licensing the Graphics Agent for Linux.

    For unproxied internet connections, type:

    pcoip-register-host --registration-code=<XXXXXX@YYY-YYYY-YYY>
    

    For proxied internet conections, type:

    pcoip-register-host --registration-code=<XXXXXX@YYY-YYYY-YYY> --proxy-server=<serverURL> --proxy-port=<port>
    
  8. Reboot the desktop.

Installing the Graphics Agent for Linux on a Physical PC

When installing the PCoIP Agent on a physical machine with a Quadro card, additional steps are required. If you installed the Graphics Agent for Linux on a virtual machine, you can ignore these steps.

Note: Install the agent first

You must install the Graphics Agent for Linux as described above before proceeding.

Important: Some GPUs are automatically configured

The Graphics Agent for Linux can use the following NVIDIA GPUs automatically:

  • K2000
  • K2200
  • K4000
  • K4200
  • K5200
  • M4000
  • P2000
  • P4000
  • P5000
  • P6000
  • RTX4000

If you are unable to start a session using any of these GPUs, follow the procedure described next.

These steps are only required when installing on a physical, non-virtualized machine with a Quadro card:

  1. Attempt to start a PCoIP session. If the connection attempt succeeds, you can stop here. Your GPU will work without further configuration. If the attempt fails, continue on; we will use the log information generated by the failed attempt in the next steps.

  2. Look in /var/log/Xorg.100.log for lines like this:

    [   293.834] (--) NVIDIA(GPU-0): LNX Linux XGA (DFP-0): connected
    [   293.834] (--) NVIDIA(GPU-0): LNX Linux XGA (DFP-0): Internal DisplayPort
    [   293.834] (--) NVIDIA(GPU-0): LNX Linux XGA (DFP-0): 1440.0 MHz maximum pixel clock
    [   293.834] (--) NVIDIA(GPU-0): 
    [   293.834] (--) NVIDIA(GPU-0): LNX Linux XGA (DFP-1): connected
    [   293.834] (--) NVIDIA(GPU-0): LNX Linux XGA (DFP-1): Internal TMDS
    [   293.834] (--) NVIDIA(GPU-0): LNX Linux XGA (DFP-1): 165.0 MHz maximum pixel clock
    [   293.834] (--) NVIDIA(GPU-0): 
    [   293.834] (--) NVIDIA(GPU-0): LNX Linux XGA (DFP-2): connected
    [   293.834] (--) NVIDIA(GPU-0): LNX Linux XGA (DFP-2): Internal DisplayPort
    [   293.834] (--) NVIDIA(GPU-0): LNX Linux XGA (DFP-2): 1440.0 MHz maximum pixel clock
    [   293.835] (--) NVIDIA(GPU-0): 
    [   293.835] (--) NVIDIA(GPU-0): LNX Linux XGA (DFP-3): connected
    [   293.835] (--) NVIDIA(GPU-0): LNX Linux XGA (DFP-3): Internal TMDS
    [   293.835] (--) NVIDIA(GPU-0): LNX Linux XGA (DFP-3): 165.0 MHz maximum pixel clock
    [   293.835] (--) NVIDIA(GPU-0): 
    [   293.835] (--) NVIDIA(GPU-0): DFP-4: disconnected
    [   293.835] (--) NVIDIA(GPU-0): DFP-4: Internal DisplayPort
    [   293.835] (--) NVIDIA(GPU-0): DFP-4: 1440.0 MHz maximum pixel clock
    [   293.835] (--) NVIDIA(GPU-0): 
    [   293.835] (--) NVIDIA(GPU-0): DFP-5: disconnected
    [   293.835] (--) NVIDIA(GPU-0): DFP-5: Internal TMDS
    [   293.835] (--) NVIDIA(GPU-0): DFP-5: 165.0 MHz maximum pixel clock
    [   293.835] (--) NVIDIA(GPU-0): 
    [   293.835] (--) NVIDIA(GPU-0): DFP-6: disconnected
    [   293.835] (--) NVIDIA(GPU-0): DFP-6: Internal DisplayPort
    [   293.835] (--) NVIDIA(GPU-0): DFP-6: 1440.0 MHz maximum pixel clock
    [   293.835] (--) NVIDIA(GPU-0): 
    [   293.835] (--) NVIDIA(GPU-0): DFP-7: disconnected
    [   293.835] (--) NVIDIA(GPU-0): DFP-7: Internal TMDS
    [   293.835] (--) NVIDIA(GPU-0): DFP-7: 165.0 MHz maximum pixel clock
    
  3. Note the names of the outputs with the highest maximum pixel clocks (as many as four will be shown). In the above example, you would note DFP-0, DFP-2, DFP-4, and DFP-6.

    Note: Systems with fewer than four displays (Quadro K series)

    If there are fewer than four outputs in your system, note them all. K-series cards only support two enabled outputs at a time, but may show more.

  4. Create a file called /etc/X11/xorg.conf.d/10-pcoip.conf:

    touch /etc/X11/xorg.conf.d/10-pcoip.conf
    
  5. Open /etc/X11/xorg.conf.d/10-pcoip.conf in a text editor.

  6. Paste the following text into the file:

    Section "Screen"
    Identifier "dummy_screen"
    Device "dummy_videocard"
    Option "UseDisplayDevice" ""
    Option "ConnectedMonitor" ""
    Option "Monitor-" "Monitor0"
    Option "Monitor-" "Monitor1"
    Option "Monitor-" "Monitor2"
    Option "Monitor-" "Monitor3"
    Monitor "Monitor0"
    EndSection
    
  7. Populate the ConnectedMonitor and UseDisplayDevice settings with the display IDs you noted earlier, as a comma-separated list. Using our example (your values may be different):

    Option "UseDisplayDevice" "DFP-0,DFP-2,DFP-4,DFP-6"
    Option "ConnectedMonitor" "DFP-0,DFP-2,DFP-4,DFP-6"
    
  8. Next, map these output values to your expected displays. Modify the monitor options to correspond to the displays in the previous step. Each output should be mapped to a monitor identifier from one of the Monitor sections in 10-pcoip.conf.

    Continuing our example, we would map the four outputs to four monitors like this (yours may be different; for example, you may only have two outputs):

    Option "Monitor-DFP-0" "Monitor0"
    Option "Monitor-DFP-2" "Monitor1"
    Option "Monitor-DFP-4" "Monitor2"
    Option "Monitor-DFP-6" "Monitor3"
    
  9. Save and close 10-pcoip.conf.

  10. Attempt another PCoIP session. If the session is still unsuccessful, and you have a Quadro K series card, repeat steps 7 and 8 with a different output combination, e.g. if you tried DFP-3,DFP-4, try DFP-1,DFP-2. Due to driver differences certain output combinations may not work.

  11. To prevent the NVIDIA driver from changing the kernel mode setting, add the nomodeset parameter to the GRUB configuration:

    1. Open /etc/default/grub in a text editor.

    2. Add nomodeset to GRUB_CMDLINE_LINUX_DEFAULT.

    3. Save and close the file.

    4. Rebuild the GRUB configuration:

      sudo grub2-mkconfig -o /boot/grub2/grub.cfg
      
    5. Reboot the machine.

  12. Attempt a PCoIP connection again. The connection should succeed.

    If the session does not start, make sure that the displays are correctly configured.

Once you've installed the software, you can configure it, register licenses, or connect to it.

Note: Desktop user interfaces will only be available using PCoIP

Once installed and running, the PCoIP Graphics Agent for Linux takes over the graphics subsystem which is then unavailable to hypervisors. You can only view the graphical user interface when connecting with a PCoIP client.

For example, you cannot view an ESXi virtual machine console through VSphere; you must connect to the machine using PCoIP.
