Use Canon CanScan LiDE 60 under Ubuntu 8.04

Yesterday, I needed my scanner the first time after installing Ubuntu 8.04. In Ubuntu 7.10 I could use the scanner as normal user with xsane. Now running

xsane
let to the following error message:

Segmentation fault
whereas running xsane as root with

sudo xsane
works.

The following shows the current status of my investigation.

sane-find-scanner
let to the following output:

# sane-find-scanner will now attempt to detect your scanner. If the
# result is different from what you expected, first make sure your
# scanner is powered up and properly connected to your computer.

# No SCSI scanners found. If you expected something different, make sure that
# you have loaded a kernel SCSI driver for your SCSI adapter.

found USB scanner (vendor=0x04a9 [Canon], product=0x221c [CanoScan], chip=GL842) at libusb:006:008
# Your USB scanner was (probably) detected. It may or may not be supported by
# SANE. Try scanimage -L and read the backend's manpage.

# Not checking for parallel port scanners.

# Most Scanners connected to the parallel port or other proprietary ports
# can't be detected by this program.

# You may want to run this program as root to find all devices. Once you
# found the scanner devices, be sure to adjust access permissions as
# necessary.

Therefore, the scanner was found. But:

scanimage -L
let to the following error message:

Segmentation fault
Running the same as root:

sudo scanimage -L
let to:

device `v4l:/dev/video0' is a Noname Pinnacle PCTV 310i virtual device
device `genesys:libusb:006:008' is a Canon LiDE 60 flatbed scanner
That showed the same access rights problems.

But what to do to run xsane as normal user? Quite some time searching via: https://help.ubuntu.com/community/ScanningHowTo --> https://wiki.ubuntu.com/HardwareSupportComponentsScanners --> https://wiki.ubuntu.com/HardwareSupportComponentsScannersCanon --> http://www.zepan.org/index.php/2006/01/29/the-canon-lide-60-and-ubuntu-dapper/ let me to the assumption, that the missing /etc/udev/rules.d/45-libsane.rules could be the reason. Therefore I copied this file from my old Ubuntu 7.10 installation into /etc/udev/rules.d/. It contained among others, the following lines:

# Canon CanoScan LiDE 60
SYSFS{idVendor}=="04a9", SYSFS{idProduct}=="221c", MODE="664", GROUP="scanner"
But that didn't solve the problem. In fact, studying the files in /etc/udev/rules.d/ I belief that the way how to describe devices has changed since Ubuntu 7.10. Now it seems to be on a higher abstraction level, that might be a reason, why /etc/udev/rules.d/45-libsane.rules wasn't there in the first place and I assume, it is not needed there any longer.

Google Search let me to the following: https://bugs.launchpad.net/bugs/132219 which seem to be the same bug. I confirmed that bug and hope that somebody finds a solution. As the assumption is, that Samsungs proprietary driver might have contributed to the problem, I plan to also contact Samsung. Lets see, how long it will take to solve this problem. In the meantime, it looks as if I have to use my scanner as root :-(( .

Automatically mount a ntfs hard disk at login in Ubuntu 8.04

Ubuntu 8.04 automatically detects connected hard drives (such as a second drive with an NTFS partition). NTFS hard drives are not mounted automatically by default in Ubuntu 8.04. Instead they need to be mounted manually e.g. via clicking onto them in Nautilus. Sometimes it is desirable that such a NTFS drive will be automatically mounted at login (e.g. when you want to run a script that uses these drives at startup). This can be done via: 1) Make a mounting point for that drive sudo mkdir /media/Backup_HD Note: Replace "Backup_HD" with whatever name you like. 2) Edit /etc/fstab: sudo gedit /etc/fstab 3) Add the following text in fstab: /dev/sdb1 /media/Backup_HD ntfs defaults,locale=en_US.UTF-8 0 1 Note: Replace "/media/Backup_HD" with the name you choose in the 1st step. Furthermore, replace "/dev/sdb1" with the actual value for the hard disk you want to mount automatically. Note: If you don't know what value you should use instead of "/dev/sdb1&

How to make screenshots and screencasts easily in Mac OS X?

In Mac OS X you can take a screenshot of the complete screen by pressing Command-Shift-3 and a selection of the screen by pressing Command-Shift-4. This is usually sufficient enough, but if you try to use this key combination to capture a screenshot of a movie running in the Mac OS X DVD Player you will be surprised to find out that this doesn't work. The same is true for the built in Grab Application. If you still want to do capture a picture from a DVD you could use the screen-capture shell utility in the Terminal application - as described in several webpages. But if you would like something more convenient you could use an application such as Jing ( http://www.techsmith.com/jing/ ). It allows you not only to take a picture even from a movie running in the DVD Player but also to make a short videos of the your screen and provides several options to edit, save and share this pictures and videos afterwards. There is a Free version available as well as a Pro version with more f

Use Western Digital WDH1NC10000E My Book World Edition 1TB NAS network drive as backup destination for time machine on Mac OS X 10.5

Image
As my 500GB Time Capsule has reached the limits (my Macbook and the iMac of my wife used it as backup destination for Time Machine ), I decided to buy another backup drive and settled with the Western Digital WDH1NC10000E My Book World Edition 1TB NAS external drive. The main advantage (besides the price: I bought it fo r EUR 146,95 (incl. VAT and free transportation) for me was that I could easily connect it to a free Ethernet port of my Time Capsule - at least that was what I did expected. But after I connected the My Book to my network as discribed in the My Book manual, I had to discover that although it was available in the finder and I could manually copy files to it, it wasn't available in Time Machine as a back up destination. Furtunately obvioulsly others experienced this problem before and after some googling I came to the solution described in the post "Time Machine backups on network shares in Leopard" from Florian Kruse. Following the steps described the
