Sidebar: Linux on a Laptop

Because many components of notebook computers are custom-built, such systems present special challenges for Linux. To see how Linux would perform on the road, I took Red Hat Linux 6.1 for a test-drive on a Gateway Solo 9300. I restarted the Solo with Linux.

Nearly one-third of the screen remained blank! But I found an invaluable Web site, Linux on Laptops, where I located advice for fixing the display problem.

Then the internal modem died. Most built-in notebook modems require Windows software and therefore don't work with Linux. Fortunately, a PC Card modem works fine, so I plugged in an old 28.8-Kbps model to get online.

But the USB and Firewire ports didn't work. This is a major hole in Linux support. The next stable Linux kernel, version 2.4, is expected to close this gap.

Bottom line: Avoid putting Linux on a new notebook computer. It takes time for small fixes to be implemented for new hardware. An older laptop will probably work better with Linux.

Sidebar: Quain's Top 10

Are you thinking of installing Linux on your computer? Before you do, consider these 10 tips -- and don't be afraid to consult the user's guide.

1. Set aside a weekend. It's possible to install Linux in a couple of hours. But chances are, you'll need more time.

2. Stick with even numbers. Stable versions of Linux end in even numbers (such as Linux 2.2); odd-numbered ones are works in progress.

3. Check tech support's business hours. Don't try to install Linux in the middle of the night -- the folks in technical support may not be there to help you.

4. Check system compatibility. Make sure that all of the peripherals on your computer are supported by Linux, especially your modem.

5. Read all of the instructions carefully. Installing Linux is not as easy as installing Windows, so make sure you're familiar with all of the commands.

6. Back up everything. Before you start partitioning hard drives, copy your work to another machine or storage device.

7. Write down all of your system's specs. Make a list of system components, including the type of hard drive you use. Tech support might need that information if you run into problems.

8. When in doubt, "dual-boot." If possible, set up your system to work with Windows and Linux. That way, you can always go back to your old software.

9. Make sure you have enough disk space. The minimum is 300 MB, but plan on having at least 600 MB.

10. Seek advice online. Millions have already put Linux on their PCs. If you need help, look for it online.
