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.

After installing Ubuntu 8.04 LTE (for the reasons mentioned in my previous post ), I started customizing this machine so that all my periphery devices are supported again and all additional software will be added and configured to my needs. Printer setup First, my printer should work again on my Ubuntu machine. I have bought my SAMSUNG CLP-300 Colour Laser Printer because of its good price/performance ratio and its platform independence (Windows, Mac OS X and Linux support was advertised). I used the closed-source driver from Samsung (current version is CLP-300 Unified Linux Driver ver.2.00.97 ) before. Now, I followed the recommendation on OpenPrinting database of Linux Foundation to give the open source printer driver foo2qpdl a try (following the short installation instruction on that site). Printing a test page and printing from Firefox worked immediately. Strangely, printing from OpenOffice needs some additional work as it didn't work. It is described in the section "S...
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...
