For the public good and for your own future reference please record any FAQs here, even if you can only supply the Q
Getting help
- Q: How can I find the answer to a question which isn't here?
- A: Use the search tool in the mailing list archives, or put it here and wait for someone else to fill in the A:.
See also Live GIS Disc/Errata/8.0
Usage
Getting started
- Q: What's the live user's name and password?
- A: user/user. See the passwords.txt file on the desktop for application specific database user/passwords.
Hardware Drivers
- Q: How do I get my Wifi working?
- A: Due to licensing issues a number of proprietary firmwares can not be included on the disc, you must download them yourself. We don't have the right to redistrubute them.
- You will probably need a wired network connection to download the drivers.
Start button → Preferences → Aditional Drivers
It will search for available drivers ... this will take a little while.
Select the driver if you wish, and hit "Apply Changes". If you do not have a working network connection this will likely fail without telling you why.
- After the drivers are installed you can look in /var/cache/apt/archives/ for the deb packages, copy them over to another USB drive, then upon a fresh boot copy them back there and use 'apt-get' to install them. If you mount the other USB drive and the OSGeoLive USB drive on another computer, you can even copy these files into a directory in the Live's USB. These will then be available in the (for example) /cdrom/extra_debs directory. You could even stash a little script in there to install it all automatically.
Customizing
- Q: How do I set the drive volume name on the live USB drive?
- A: From a Linux computer, plug it in and mount it, then:
# limited to 11 single byte characters IMAGE_NAME=OSGeoLive80 # find devivce and mount name # for me it is /dev/sdd1 and /media/0FB5-AA29 df -h # unmount it umount /media/0FB5-AA29 # check the label mlabel -i /dev/sdd1 -s :: # set the label mlabel -i /dev/sdd1 ::"$IMAGE_NAME"
Administration
- Q: What's the root password?
- A: There isn't one. To run commands as root type `sudo <command>` in a terminal. To become root type `sudo - su`. Enter the user's password when prompted.
- Q: How do I get my dual monitors to span instead of mirror with xUbuntu?
- A: Go to the Applications → Settings menu and use the `arandr` program to drag them apart, then click the tick/check button to apply (once you start the program it's pretty obvious, the program name on the other hand is not so obvious :) For the OSGeo 5.5 Live DVD and earlier you'll have to install it yourself via Synaptic or the Ubuntu Software Center.
- Q: How do I ssh into the Live Disc?
- A: You must first install the openssh-server package:
sudo apt-get install openssh-server
Because of a bug in Ubuntu 12.04 you may also need to run:
sudo initctl reload-configuration sudo service ssh restart
- Important: If enabling remote login access you really should change the user account's default password with the passwd command.
Building the disc
- Q: How do I roll my own version of the disc?
- A: See the Live GIS Build wiki page
- Q: This app is great! How do I install it on my Ubuntu system without installing everything else?
- A: All the install scripts can be found in the ~/gisvm/bin/ directory on the disc.
