After having downloaded Skype for Ubuntu (ver. 188.8.131.52-1) 9.04 and installed it, I found a problem when trying to make a test call. Skype simply displays a message saying “Problem with audio playback”. I found a solution to this problem on the blog of Kholid Fuadi. In brief the solution is (in a shell):
- killall pulseaudio
- sudo apt-get remove pulseaudio
- sudo apt-get install esound
- sudo rm /etc/X11/Xsession.d/70pulseaudio
That brought me one step further in getting Skype to work. The next problem appearing was the fact that the internal microphone did not capture any sound/voice. Btw my laptop is equipped with an Intel AD1984HD codec device. I found a comprehensive step-by-step guide at Mage Blog.
Start alsamixer (from a shell). Turn up the gain on everything except those named something with “boost”. Press tab and turn up the gain on the capture devices. The input source is set to “internal” (in case you don’t plug in a mic in the mini-jack port).
In System -> Preferences -> Sound i have used the following settings
Play around with the setting e.g. make a test recording with the Sound Recorder in order to verify that the capture device is working properly. In Skype I found it necessary to also specify the input device manually:
I have been using linux the last 8 years with different flavors (RedHat, Debian Gentoo, Suse). Personally I like the Debian based distros the best.
Now time has come that I wanted to install Ubuntu 9.04 on my home laptop. I have noticed all the buzz around this “relatively” new distribution and how easy it is to install/use and now I wanted to see it with my own eyes. The installation was like a breeze and everything was easy to set up (WLAN, audio, additional plugins like flash, java, Adobe reader etc.).
Since I work from home from time to time I need to access the internal network at work using a VPN connection (to a Ciscoserver). I found the tutorial at McMaster University for installing Cisco VPN client on linux very useful. See the tutorial yourself, however the steps are basically:
- wget http://www.mcmaster.ca//uts/network/software/vpnclient-linux-x86_64-4.8.02.0030-k9.tar.gz
- tar xzvf vpnclient-linux-x86_64-4.8.02.0030-k9.tar.gz
- cd vpnclient
- sudo ./vpn_install
- /etc/init.d/vpnclient_init start (loading vpn client module into kernel)
- Copy an existing VPN profile *.pcf to /etc/CiscoSystemsVPNClient/Profiles
- Fire up the vpnclient: vpnclient connect YOURPROFILE
In order to connect to the Citrix MetaFrame XP I installed the Citrix Receiver from http://www.citrix.com/English/SS/downloads/details.asp?downloadID=3323. I downloaded the tar.gz file and followed the instructions . It seems as if the Citrix Receiver automatically adds itself to the firefox plugins.
Having just installed Ubuntu 9.04 on my home laptop, I wanted to import my Google Calendar (see this tutorial). It worked like a charm, however all my appointments from my Google Calendar where off by 2 hours.
It turned out that despite specifying the correct time zone (Copenhagen/Europe) during installation of Ubuntu, Evolution was still set to UTC. The fix is really easy:
- Open Evolution
- Goto Edit -> Preferences
- Change the timezone from UTC to whereever you are located
