Been wondering this for a while — how do you make a cron script that will only run once, when your server boots?
Just append “@reboot” before the command, instead of the usual time information (at least on Ubuntu Server 12.04):
After six months or so of being wowed by a little portable scanner in a doctor’s office, the spouse and I finally decided to buy one. I wanted one that’s compatible with Ubuntu, since that’s our main OS around home, so I did a little research, and found some info about the Plustek Opticslim m12 (it’s the same model that the “NeatReceipts” company rebrands for their own scanners).
Found one on Ebay, bought it (for 1/3 of the price of a NeatReceipts model), and plugged it in… and of course it didn’t work. This is the world of Ubuntu with proprietary peripherals, of course. The “Simple Scan” program that’s built-into Ubuntu recognized the make and model, oddly enough, but it wouldn’t scan, throwing up an error message whenever I tried.
I did a little bit of searching, and found a site that talked about it: http://www.fishandcross.com/blog/?p=844
Apparently, all you need to do is download the driver file mentioned from the site at http://gkall.hobby.nl/gt6816-07b3-0412.html and copy it to your /usr/share/sane/gt68xx folder. Then, just start up the Simple Scan program again, and scan away! Works really well — doesn’t auto-crop or anything like the provided Windows software does, but that’s cool. I’ll take it.
To Visitors: If you’re visiting this page, trying to find information about how to get this scanner to work, and you’re trying it years after this article was written, I can’t guarantee these instructions will work — if you know Ubuntu, stuff changes from version to version sometimes. Hacks and fixes that’ll work one year won’t always work the next.
I’ve been getting an Ubuntu server running recently (FINALLY), and in order to make it run headless (without keyboard, mouse, or monitor), there’s a few things one needs to do:
1) Enable Auto-Logins (optional)
All depends upon how you set things up, but you may want to run everything easily through a default user account — just go to “System > Administration > Login Screen”, and set it up. (These instructions are for the GUI of Ubuntu, of course — I’m not a CLI-queen, and would rather edit things quickly through an interface that I’m familiar with than search forums for hours trying to find the esoteric commands necessary to do this stuff manually, sorry.)
2) Enabling Networking With Automatic User Login
Now, you may have set up automatic logins, but noticed that you always have to enter in your account password manually anyway once your network tries to connect — took me a while to figure out this one, but just go to “System > Preferences > Network Connections”, and in the type of connection you’ll be using, make sure the option for “Available to all users” is selected at the bottom. That’s it. I feel dumb for not figuring this out long ago.
3) Enabling VNC to Run Headless
As per the instructions I found here, you have to
More to come, including the Minecraft configuration scripts!
Just installed Adobe Acrobat on linux and it’s not printing? Just giving you a crappy error message when you try to print?
When you print, instead of selecting the default printer, just select “custom” and type “/usr/bin/lp” into the box that appears to the right. Printing will continue normally.
Just one more thing in the list of easy fixes that never make it into releases of Linux.

Brother, I appreciate that you at least made an attempt at providing Linux installation files, even going so far as to provide .DEB and .RPM files.
However, none of the solutions works, and even on my version of Linux, Ubuntu 10.04, probably the most common one around, the .DEB files did next to nothing. They didn’t setup Ubuntu’s printer configuration so that the printer showed, nor did they enable the drivers to be found when I tried to install the printer manually. (The Brother HL-2270DW is apparently so new that Ubuntu doesn’t have any default drivers in its repositories.)
What did work? Selecting HL-2170W from the default drivers list in Ubuntu. Seems to work fine! :P
