Update: In Intrepid Ibex this package is now called flashplugin-nonfree-extrasound.

Hi,

as some of you may have already recognized, in Ubuntu Hardy, normale sound applications and Flash in Firefox don’t play well. For example: if you first start Rhythmbox, hear some music and later run Firefox to watch some Youtube it plays without sound.

This problem is known and there is a solution! Just install libflashsupport.

Cite from the description:

Due to various bugs in the Flash 9 plugin sound output of Flash 9 through the pulseaudio soundserver doesn’t work properly. This library adds a clutch to make Flash 9 sound output in pulseaudio possible.

For further information see http://www.pulseaudio.org/ticket/43 and http://www.pulseaudio.org/wiki/FlashPlayer9Solution

Situation: You have a computer which you want to connect to your already existing network infrastructure.

Problem: You don’t have any switch or hub available only a network card and an already connected computer.

Solution: Use bridging. Its just two clicks away… ok, not really – I don’t like clicking over ssh

So what I’ll tell you now is what I’ve learned from: http://www.barmasse.org/linux/praxishilfe/ubuntu/virtualbox.html and http://ubuntuforums.org/showthread.php?t=132515 (post from user “woedend”).

Open the file /etc/network/interfaces as root and add the lines:


auto br0
iface br0 inet dhcp
bridge_ports eth0 eth1


Then install the package bridge-utils and type as root:

/etc/init.d/networking restart

You’re dhcp server must be configured to give the br0 interface an IP address. After that, you can do everything with your external connected computer as if it where connected directly.

here is a walkthrough to set up a NIS server under Ubuntu Hardy, because the standard configuration is only for clients.

apt-get install nis
NIS domain: be creative

Then wait till the ypbind search is over (it tries very hard to find a server…) otherwise the package is not completely installed.

In the mean time, you can prepare the server.

/etc/yp.conf
ypserver 127.0.0.1

/etc/default/nis
NISSERVER = master
NISCLIENT = false

/etc/ypserv.securenets
# This line gives access to everybody. PLEASE ADJUST! Adjusted!
255.255.255.0 192.168.1.0

When the installation is complete, you can proceed with the following steps:
/usr/lib/yp/ypinit -m
/etc/init.d/nis restart

Congratulations, your NIS server is now running!

today I tried to do some online banking at www.sparkasse-zwickau.de. To my suprise, I took a very long time till the welcome page was loaded.

I checked this again with another browser: same problem. Than I tried a host outside the university… wow, it goes very fast. Hmm, and another host inside? Also fast. So I’d check the installed windows and it also worked perfectly.

I googled a bit and found that the problem is my network interface which is handled by the e1000 driver.

Some people in the ubuntu forums mentioned that the new e1000e could help.

So I got it from
http://sourceforge.net/project/showfiles.php?group_id=42302
(Version 0.2.9.5) and compiled it. Yes! It works. Its a big improvement although my feeling tells me, that the felt speed under windows is higher. But at the moment it’s enough to use the banking site without getting kicked by the time limit.

After compiling and testing it, here are the steps to get it into the system and replace the old e1000 & e1000e (you’ll have to do this after each kernel update):


rm /lib/modules/`uname -r`/kernel/drivers/net/e1000/e1000.ko
rm /lib/modules/`uname -r`/kernel/drivers/net/e1000e/e1000e.ko
cp e1000e.ko /lib/modules/`uname -r`/kernel/drivers/net/e1000e/
depmod
update-initramfs -u


Reboot & done

long time ago I wrote an article how to make the DCP-110C running under Ubuntu Feisty. One commenter wrote me, that he got it also to run with Gutsy and Hardy.

Now the time has come and some things are easier

Since Hardy (I think) the cups-packages for the DCPs are now included in the package repository. You have to enable the multiverse repo to get it.

After enabling it, run the following command to install the needed printer packages:

• apt-get install brother-cups-wrapper-extra brother-lpr-drivers-extra

After this you need to add a rule for udev to allow sane to also use the scanner. Put the following content in a file called: /etc/udev/rules.d/55-brothermfc.rules


# Udev rules file for Brother printer products.

LABEL="brother_rules_end"


This file was adapted from /etc/udev/rules.d/55-hpmud.rules. Thanks to the authors.

This worked for me and is much easier than the previous steps. But to install the scanner driver you’ll need them – the udev rule is only for making the printer also available to users of the scanner group (don’t forget to add yourself to it).

it’s now possible to remove a big part of evolution in hardy, because ubuntu-desktop does now only recommends some evolution packages.

You can easily remove them by:

sudo apt-get --purge remove evolution evolution-exchange evolution-plugins evolution-common evolution-webcal

Only the following packages will stay: evolution-data-server, evolution-data-server-common

if evince won’t print after the Hardy update, you can try the following steps which worked for me.

sudo apt-get install ubuntu-desktop (which will also add evince )

After that, printing should work again. Maybe some steps are not necessary… find it out for yourself

Nice pentecost!
