I have not tested these files.  They supposedly provide DOS3.3 and ProDOS support on Linux.

How do I increase font size in Elementary OS luna?

The text is too small to read on the screen. How do I make it larger?

http://iblogipple.blogspot.co.uk/2013/02/how-to-change-elementary-os-luna-font.html

This method is  now outdated.  New method is to install OS Elementary Tweak.  Above method will still work for other distros.

sudo apt-add-repository ppa:versable/elementary-update
sudo apt-get update
sudo apt-get install elementary-tweaks

After you can find it in System settings -> Tweaks

How do I install Elementary OS Luna as a Dual Boot with Windows?

The procedure is:

  1. Make sure you have restore CDs for your Windows installation.
  2. If you have not got them, find them or create new ones before going any further.
  3. Download the Elementary OS luna image file.
  4. Choose the amd 64 version if you have a modern laptop (bought after circa 2006)
  5. If you have an older laptop, you will need the 32  bit 386 version
  6.  If you don’t know whether to download the 32 or 64 bit version, boot the machine with any Linux live CD, and in the terminal, type: lscpu, and it will say Architecture:          x86_64 CPU op-mode(s):        32-bit, 64-bit
  7. Make the image you downloaded into a real CD.
  8. In M$ Windows, Navigate to Control Panel>System and Maintenance>Administrative Tools>Create and Format Hard Disk Partitions
  9. Right-click on either your “C” or “D” partition and choose “Shrink Volume”
  10. The result will be an area of “unallocated space”. This needs to be at least 5 gig.  I would make it at least 10 gig for good measure. You can make it more than this if your HD has sufficient free space, but I would not make it larger than 10gig for this first initial test.
  11. Set your machine to boot from the CD.
  12. Reboot the machine with the Elementary OS install CD in the drive.
  13. Elementary OS should now boot up okay.
  14. Use the “network” icon on the top right hand of the screen (between the “sound” and the “battery” indicator) to connect to your WiFi.
  15. Run the installer. It will ask you if you want to wipe out your windows installation. Do not click this option under any circumstances.
  16. Choose “something else” in the installer, and select the “unallocated space” you just created.
  17. If you are not sure of what you are doing, cancel the installation, and watch a Youtube video on the subject.
  18. http://www.youtube.com/watch?v=3HANcetKsqc
  19. Create a new partition in this unallocated space.
  20. You can now set the installer to format this new partition.
  21. If you are happy everything is correct, proceed with the installation.
  22. The installer will ask you which drive for bootloader installation. Choose the partition  you are installing Linux onto. If you choose your Windows partition, it will install the grub menu there, and you don’t want it to do this if you are on Windows Vista or later.
  23. When the install is finished the machine will eject the CD from the drive and ask you to press any key to reboot.
  24. At this stage, change your default boot option to boot from the Hard Drive. This prevents accidental re-booting of any live CD you happen to leave in your drive.
  25. The machine will now reboot, and you will be back in Windows as normal.
  26. Now, here comes the cunning part. You need to add an entry to the Windows  boot screen so that there is an option for Linux.
  27. An easy way to do this is to use EasyBCD which is available from http://neosmart.net/EasyBCD/
  28. Download and install EasyBCD, and choose “neosmart linux”. Add an entry which selects your linux partition.
  29. Reboot the machine. If it doesn’t work, go back to EasyBCD, delete the entry, and try another setting.  The Neosmart Linux setting definitely works.
  30. Last but not least, if you get stuck, there is a program called Easus Partition Master which will allow you to view and modify the partions on your laptop.

How do I Dual Boot Vista and Linux?

The “WUBI” installer, which allows you to install Xubuntu etc inside Windows Vista is not included with the latest distro (12.04), so what can you do?

The first option, is to install an earlier version, say 11.10 and go for the “Distribution Upgrade”.

A drawback with WUBI is that it creates a very large file called “root.disk” which contains a disk image of your Linux installation. If you get an error on this file, you sometimes cannot recover your data. This does not happen very often, but using WUBI, there is a definite risk of a loss of data.

So what is the alternative method?

The method I used was to use “EASEUS Partition Master 6.5.1 Home Edition” (Freeware) to create a blank partition of 10 gig within the “DATA” partition on my Vista Laptop. Then I downloaded Xubuntu 12.04 “alternate” installer.

I then used the alternative (non-graphical) installer to erase and partition the 10 gig sub-partition I had created. The installer creates the sub partitions within this partition i.e. the “swap”and “home” partitions.

Warning: it is very easy to erase your Windows installation by mistake! If you are not at all sure, choose “go back”!

It is easy to tell which partition is which because you know if you created a 10gig partition, the size of the partition must be this value, or approximately this value if you did not specify 10gig exactly. If the value is the size of your whole drive, then it is the wrong partition, and you don’t want to format it!

To understand the procedure without running the risk of wiping out your Windows installation, insert a 4 gig or larger size USB flash drive and use the Linux installer to partition and install to the USB flash drive. You can then set your machine to boot from that as a test.

Linux on a USB flash disk

I decided to try the experiment of putting Xubuntu on a 4gig USB stick. The reason for this being I was running out of space on my hard disk.

To do this, you have to download “Xubuntu 12.04 Alternate Install”. This gives you a non-graphical installer which will fit Xubuntu onto a smaller 4gig partition.

You have to chose “guided use the whole partition.” You know which disk is which because it tells you what the space is. If it is only 4gig, then it has to be the USB stick and not the HD in the main part of the machine.

You have to be a bit careful with this parititioner because it allows you to wipe out your Windows installation.

If you are on a wireless connection using your laptop, you need to make a note of your wireless access name and the password.

Then you need to set the startup devices so that the USB stick is the first boot device.

When the USB stick is not in the machine, thn it will boot into Windows.

When booting from the USB stick, the GRUB menu gives you the option to boot back into windows, which is cool.

Virtualbox and Laptop

The trouble with Virtualbox and Linux, is that you don’t know whether the bug is with virtualbox or with the Linux distro you are trying. 

So my experiment is to have an identical version of Linux running on Virtualbox and on the laptop at the same time. 

Good idea. 

Currently checking out Ubuntu 10.10 with Macbuntu 10.10 installed. So far it is solid.

Open Suse 11.4 Live CD

If you have been trying Kubuntu, and have had enough of it, the alternative is the “K” version of Open Suse.

The main Open Suse page is here.

http://www.opensuse.org/en/

However, it looks like you have to download a 4.7 Gig DVD. In fact you do not, click the link below, and then click on the “Live KDE” icon, where it says “A KDE desktop you can run from CD or from USB stick”. This takes about 40 minutes to download on ADSL.

What is a Deb file?

A “Deb” file is a software package which has been compiled for the Linux Debian system.

However Deb files are not like “BASIC” programs you can just load in as you could on the Commodore 64, BBC Micro, Apple II, or Amiga A500.

A “Deb” file has to be created specially for the type of computer and version of the operating system.

Before downloading and trying to install “Deb” files, be sure they pertain your Computer and version of Linux.
