GNOME 2.28 Released

Ubuntu 10.04 : Lucid Lynx

Launchpad 3.0 is here!

New UI and more.

The GNOME

Desktop is

released every

six months and

contains many

new features,

improvements,

bug fixes and translations.

GNOME 2.28 continues this

tradition. To learn more about

GNOME and the qualities that

distinguish it from other

computer desktop

environments (such as

usability, accessibility,

internationalisation, and

freedom) visit the About

GNOME page on our website.

Speaking via video to UbuCon at

the Atlanta Linuxfest, Mark

Shuttleworth announced that the

code name for the 10.04 Ubuntu

release would be "Lucid Lynx". It

will be an LTS version featuring 3

years support for the desktop

version and 5 years for the

server version. This will be the

third LTS version, proving that

Ubuntu can not only deliver a

new version every 6 months, but

also an LTS version every 2nd

year, something Mark is very

proud of.

The Launchpad team is proud to

announce the release of Launchpad

3.0!

• a new clearer web interface with in-

line editing

• personal translation dashboards: see

what needs your attention

• automatically updated diffs during

code reviews.

Visit Launchpad to see our new web

interface. You can now view more

information on many pages without

scrolling, particularly on people and

project profile pages.

Speaking briefly of what we can expect to see in the

Lucid Lynx, Mark talks of cloud computing and GNOME.

Mentioning our relationship with Debian, Mark hopes to

continue expanding that relationship in the hope of

bettering both distributions. In closing Mark asks our

community to search out those who put in so much work

delivering a quality Ubuntu product to us, and to give

them all a big thanks. We think a big thanks is also

deserved by Mark for his oversight and tireless work on

our behalf.

And the web interface is now faster:

you can update more data, including

almost everything on bug report

pages, without reloading the page.

GNOME 2.28 includes all of the

improvements made in GNOME

2.26 and earlier. You can learn

more about the changes that

happened in GNOME 2.26 from

its release notes.

COMMAND & CONQUER

yourself tapping an

extra key on your

laptop, only to

realize that it isn't bound to

anything, and then finding out

that the shortcuts program

doesn't recognize the key?

Well, I ran into a similar

problem when setting up

Openbox on my netbook, and

so I thought I would show you

how to bind keys to functions,

even if it seems that they are

not recognized.

(XF86AudioMute,

XF86MonBrightnessDown, a, b,

and so forth). If it displays

NoSymbol after the keycode,

there is no keypress bound to

that keycode yet, and you can

skip to step two. If neither the

key returns nothing, it is time

to try showkey.

dmesg|tail -5

required in the tty0 console. To

start, you must create the

.Xmodmap file. This can be

done by using the touch

command, or just editing it in

gedit and then saving the file.

Entries in the file should be in

this format:

If something like this

appears in the dmesg output -

atkbd.c: Unknown key pressed

(translated set 2, code 0xf1

on isa0060/serio0).

Switch to tty0 (by hitting ctrl

+ alt + F1) and log in as your

user. Once logged in, enter the

command:

atkbd.c: Use 'setkeycodes

e071 <keycode>' to make it

known.

keycode <Xkeycode> =

keysymbol

A few examples would be as

below:

- you can map the scancode to

a keycode. You can do this by

either using HAL or

setkeycodes (kernel tool), as

shown in the dmesg output.

The further reading section at

the end of this article offers a

link to HAL's keymap quirks

page. I will not go into detail in

the article, since it is quite rare

(in my experience) that it is

necessary to do this.

showkey

keycode 153 =

XF86MonBrightnessDown

Step One: Key

Recognition

This program will return

keycodes of keys pressed, and

automatically quit 10 seconds

after the last keypress. Once

the command is run, hit the

key(s) you want to test, and

record any keycodes that it

returns. If neither of these

options returned a keycode, it's

time to see if the key has a

scancode.

keycode 154 =

XF8MonBrightnessUp

First we need to find out if

the key is recognized by the

kernel. Open a terminal and

run the command:

Step Three: Testing

Keycodes

First run the command:

xev | grep -A2 --line-

buffered '^KeyRelease' | sed

-n '/keycode /s/^.*keycode

$[0-9]*$.* (.*,

$.*$).*$/\1 \2/p'

Step Two: Binding

Keycodes

xmodmap ~/.Xmodmap

Then you should be able to

add the keys to whatever

function you need. If not,

revise the keycodes and

keysymbol names, just in case

To do this, press the key you

want to test, and then check

dmesg with:

This will output the keycode

followed by the keypress name

I will focus on binding

keycodes to keys in Xorg, since

most multimedia keys aren't
