A friend presented me with an issue a while back where certain buttons on his Logitech keyboard, specifically the zoom bar, didn’t work properly under Ubuntu. After some searching, I found a site that codes Linux drivers for these devices, and directed him to it. They have drivers for Debian, CentOS, Fedora, Mandriva, Mint, RedHat, Suse, and Ubuntu. The full list of supported devices is below.
After testing, he came up with a set of instructions (originally posted at another site) and I have rewritten them here in a [hopefully] more accurate process.
- Head over to HIDPoint
- Fill in the requested information on the download page (mouse/keyboard/OS/etc…), you can ignore the email field if you wish and select download. Make sure you select correctly if you’re using a 64-bit or non-64-bit OS.
- On the next screen, select the link “Download Now“, and save the file to your hard drive.
- Navigate to wherever you downloaded the file to.
- Right click on the file, and go to Properties > Permissions and check the box for execute.
- Double click on the file and select “Run In Terminal“. Type “Y” then hit “Enter”.
- Follow all on screen prompts.
- After Installation is complete, you will need to reboot.
Would you only ever have one house key? Car key?
Would you only get one picture of your child? Your spouse?
Then why would you not treat your computer data the same way?
Being a computer technician, I can’t tell you how many times (a day!) I hear “Will this affect my data/hard drive/information/etc…” You know who I always hear that from? People who don’t have backups.
If you’ve ever lost an important file because of a system crash, hard drive failure, or mistakenly deleted it, or even worse — suffered at the hands of a theft or destruction from a computer virus or malware, then you’ve likely already learned this very important lesson (rather painfully, no doubt).
If you’re working on something that is so important you’re worried about it, why wouldn’t you keep a second copy of it?
I’ll tell you exactly why: Because it takes time and effort.
But for something so important, there really are very simple (and inexpensive) solutions.
You could burn a CD or DVD. CDs only hold about 700MB of data, and most people have far more than that. Dividing up folders and folders of pictures and music over 700MB CDs is frustrating at best. Download movies? Most won’t even fit on a 700MB CD. There’s DVDs, sure. However, one of the biggest drawbacks to optical media is their shelf life (5 years or so, often times much less). Optical media degrades with exposure to light, heat, and may warp if stored vertically. Rewritable media has an even shorter shelf life, as every write cycles “burns” the disc and degrades it further. That leaves you with a very real possibility that when you go to reach for your data, it won’t be there.
You could use an external hard drive. External hard drives are just as inexpensive (per MB/GB) as optical media (sometimes more so), and have a longer shelf life. They are a great backup destination for large amounts of data, and can be backed up to quickly and easily. Unfortunately, magnetic media can’t be exposed or stored near strong electrical or magnetic fields. They are also fragile while powered on, they too do degrade over time, and can sometimes fail without warning. You could spend some money on a RAID array and have a nearly fail-safe solution… but it doesn’t protect against fire or theft.
You could backup to a flash drive. Unfortunately flash drives are actually the smallest capacity and the highest cost of any removable media. They are great for carrying around a small amount of data (some files back and forth from work, for example), but as a backup solution, they are impractical.
I prefer the set-it-and-forget-it approach of online backups, and I really encourage you to try the same.
Online backups charge you a small fee (usually monthly or yearly) and store your files on a remote server in case of a disaster. All you need is a reasonably fast internet connection. Storage and retrieval are limited to the speed of your internet connection, but this really takes the effort out of it. Backups are done routinely in the background and happen automatically. If disaster ever strikes in the form of a lost file, you simply connect to the online service and re-download your file.
So here’s a few suggested services and the last pricing structure I recall them having and my thoughts on each:
CrashPlan (Windows, Mac, Linux)
Cost: Free if you’re backing up to an external drive or a friends computer (even off site); $59/yr for one computer or $100/yr for all your computers to back up to their storage center (“CrashPlan Central”).
Pros: Inexpensive, unlimited storage space. Easy to use application. Supports local destinations for rapid backups and restores. Supports encryption. Cross-platform. Data de-duplication reduces upload size on changed files.
Cons: Requires payment for the service term up front. Minor display issues related to GDK_NATIVE_WINDOWS under Linux. Some features require additional “CrashPlan Pro” license.
My thoughts: If you’re a Linux user this is the service for you. Slightly cheaper than Mozy for a single computer for the year; much cheaper for multiple computers.
Mozy (Windows, Mac)
Cost: Free for the first 2GB of storage; $5/mo per computer for unlimited.
Pros: Inexpensive for a few PCs. Easy to use application. Option to display icons on files to show what is backed up and what is pending. Easy to use options. The option to order restore DVDs is available for disaster recovery, but it is expensive.
Cons: No plans for a linux client. Slow transfer speed.
My thoughts: For Windows-only users this is a great service. Automatic monthly payments make the cost easy to budget.
JungleDisk (Windows, Mac, Linux)
Cost: $2-5 per month and $0.15 per GB. Transfer rates apply with storage on Amazon S3, or no transfer fee with storage on Rackspace.
Pros: The price structure is fair — pay for what you use. A very reliable infrastructure in the two providers. Encryption. Multiple datacenters to assure your data is safe. They’ve been around for a while. Inexpensive for small amounts of data. Data de-duplication reduces storage space, cost, and upload size.
Cons: Can get expensive with large amounts of data. The application is somewhat confusing at first.
My thoughts: Another good cross-platform provider. Although a bit more costly than CrashPlan or Mozy, the thought of multiple data centers is appealing to those with mission-critical data.
Symform (Windows, Mac, Linux [Beta])
Cost: First 10GB free, $0.15/GB/Month each additional (or free if you contribute)
Pros: Generous amounts of free space, and no limits on the amount of space you can earn if you contribute storage. Contribution is not required. Interface is simple, and setup is easy. Support can be paid by contributing space as well.
Cons: No option yet to select files to exclude, or for single file restores. Contributing requires setting up port forwarding.
My thoughts: Symform is a good, spacious alternative to other backup providers, and especially appealing for users who have space to contribute.
Bottom line: There really are no “perfect fit” backup solutions, but the best practice is to use one or more different methods and keep at least one at a second location (“off-site”). Worst case, your home could burn to the ground or be broken into, and your optical discs and external hard drives would be forever gone. Online backups do alleviate that fear, but rely on an internet connection to recover your data. I’ve found it best to keep one backup copy on an external hard drive (for accessing large amounts of data quickly) and use an online provider for worst-case recovery (the backup hard drive crashes, or fire or theft claims the backup). It’s all about how valuable your data is to you.
Comments and feedback are welcome, as always.
Fedora (and Ubuntu) Linux users looking for more screensavers should install the package xscreensaver-gl-extra via their favorite package manager:
Use yumex, or via command line:
sudo yum install xscreensaver-gl-extra
Use Synaptic, or via command line:
sudo apt-get install xscreensaver-gl-extra

This occurs when Compiz is enabled — you need to change the number of desktops through the Compiz Config Settings Manager (CCSM)
To work around the issue, install ‘ccsm’, then under System->Preferences->Look
& Feel choose “CompizConfig Settings Manager”. In the new window choose
“General Options” and from the tab list choose “Desktop Size” and change the
top slider to how many workspaces you need. This may not change the number of
workspaces immediately – you may need to log out and log in again.
