Ricoh Drivers for Ubuntu 10.10

October 12, 2010 Leave a comment

If you try to compile r5u870 driver for Ricoh webcams under Ubuntu 10.10 you’ll fail due to a recent renaming of some functions in the linux kernel.

In particular:

usb_buffer_alloc() is renamed to usb_alloc_coherent()
usb_buffer_free()  is renamed to usb_free_coherent()

For more information: http://kerneltrap.org/mailarchive/git-commits-head/2010/4/30/32383

To avoid this problem, make this substitution in the usbcam_util.c file that can be found here: ttp://www.palmix.org/download/r5u870_k2.6.30_i386.tar.bz2

Debian Release Name

Hi. Today Today I leardned about the relationship between the name of the Debian’ releases and the names of the characters of “toy Story”. So I want to explain it to you.
The names of the Debian’ releases come from “Toy Story”, the famous Pixar’s film (link). This is true since the release 1.1, released in the 1996. By this time, Bruce Perens had taken over leadership of the Project from Ian Murdock and Bruce was working as system programmer at Pixar.

Thinkpad IBM audio buttons

October 6, 2010 Leave a comment

Hi.
Do you have an ibm thinkpad?
Do you have gnome?
Do you have ubuntu?
You can not associate the hardware audio buttons with the volume indicator?
The most likely solution is to add ONE of the following lines to the “/etc/rc.local” file:

cp /sys/devices/platform/thinkpad_acpi/hotkey_all_mask /sys/devices/platform/thinkpad_acpi/hotkey_mask

Or:

echo 0x00ffffff > /proc/acpi/ibm/hotkey

… and, maybe, the buttons will work… :)
