A friend of mine had a problem. With the upgrade to Ubuntu 10.04 his Logitech webcam didn’t work anymore with skype. The solution was a bit tricky, because he had all he need, means skype-wrapper was installed correctly. Mehr…

Since updating to Lucid, a Dell Inspiron 1501 with an Radeon Xpress 200M video card had become problems after going into suspend mode. After waking up it was not possible to reactivate the screen. It stays black and the only possibility was to power off. Mehr…

A new base feature from Ubuntu 9.10 is the S.M.A.R.T. notifier which informs you whenever your harddrive reports an error. Before Karmic Koala you had to install smart-notifier which does the same job but was not in the base distro. Screenshot after the break… Mehr…

Seit Ubuntu 9.04 (Jaunty) wurde der Update-Manager so umgestellt, dass er die Updates nun immer sofort anzeigt, statt als Symbol in der Taskleiste darüber zu informieren. Mehr…

Update: Leider scheint der Ton verzögert anzukommen (auch wenn man in der /etc/pulse/daemon.conf die beiden Werte noch anpasst), was bei Videoübertragung unschön ist.

Da ich momentan sehr viel skype hatte ich das Problem, dass ich während Skype online war, keine andere Audioquelle anhören konnte. Durch einen tollen Hinweis im PulseAudio Wiki ist dies jetzt wieder möglich. Mehr…

Es hat sich für mich als praktisch erwiesen, die Pause-Taste welche sonst unbenutzt auf der Tastatur herumliegt zum Ausschalten des Bildschirmes zu nutzen. Dies schont zudem den Akku auf einem Laptop wenn man ihn kurzzeitig nicht benötigt (in Kombination mit dem Thinklight Plugin für Pidgin ist dies eine ganz praktische Sache – sofern man einen IBM hat).

Update: Die alte Pidgin 2.5.2 Version ist jetzt auch mit dem normalen Update wieder lauffähig.

Hallo,

wie einige seit 9.3.2009 bemerkt haben, funktioniert Pidgin nicht mehr mit dem ICQ Netzwerk. Doch es gibt Abhilfe von Felix Geyer! Mehr…

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

Hi there…

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.

Hi,

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!

Bye,
Sven
