Following closure of the PCUG Centre at Holder, most of the previous info on this page is no longer relevant. A brief summary of some has been retained, in case needed with the remaining PCUG equipment at U3A.



support by peripherals at U3A is unknown:

  • IPv6 may be left enabled on your computer
  • if doing so, then preferably disable DHCP6 (temporariliy) to improve network connection speed.


availablity unknown


If connecting via a Cat5 cable, then a network configuration of DHCP or obtain address automatically should provide access to the LAN and Internet

  • avoid using static addressing, which is likely to either:
    • be in the wrong network and not work at all or
    • clash with other addresses on the LAN

Firewall Setting

In order to use a printers at the U3A, the firewall on your computer may need to have the Ethernet zone set to Trusted/Internal/Open

  • not that the level of protection in the firewall at U3A has not been assessed






Both PCUG projectors are compatible and routinely used with Linux.


  • use the HDMI cable, if your computer has a suitable socket/adaptor
  • otherwise use the VGA cable
    • it is usually necessary to bypass the video splitter box, which appears not to pass projector/monitor parameters the the computer
  • use the remote control ofhte projector to select the input source, according to cable type


  • log out and relog in to the computer after connecting the projector
    • in some cases it may be necessary to reboot the computer, in order for the projector to be correctly recognised
    • most notebooks/netbooks require that the output to the projector be configured as a second "monitor"
  • see the article Using an External Display or Projector with a Notebook in this wiki, for further guidance and troubleshooting


The high resolution Canon scanner is not Linux compatible

  • scans produced with it using Windows can be saved to formats which are Linux compatible
    • lossless formats such as TIFF, PNG or PNM may be the best choice for images that are to be enhanced.


no longer accessible to members'

Training PC

no longer have Linux installed, although should be compatible with most Live CD.
