25 AristotlePagaltzis 4 !! How to run [KDE] on Ubuntu or [GNOME] on Kubuntu without a reinstall
5
6 Simply do one the following:
7
8 <verbatim>
9 sudo aptitude install kubuntu-desktop # to install the Kubuntu KDE desktop
26 AlastairPorter 10 sudo aptitude install xubuntu-desktop # to install the Xubuntu XFce desktop
25 AristotlePagaltzis 11 sudo aptitude install ubuntu-desktop # to install the Ubuntu GNOME desktop
12 </verbatim>
13
14 After that, log out, and at the login screen, pick [KDE], [GNOME] or [XFce] from the ''Sessions'' box as you prefer.

16 !! Resizing NTFS partitions on install
17
18 Ubuntu supports NTFS partition resizing during the install process. To do this, select the partition you wish to resize, and enter a size that is smaller than the existing size. It will shrink the partition down to the new size, and leave empty space afterwards.

20 !! No DMA on IDE drives
21 You may have to manually add your ide chipset module to /etc/modules before ide-cd.

19 AlastairPorter 29 !! How can I tell what to put in my sources.list file for some specific/obscure packages?

33 Have a look at http://ubuntu.wordpress.com/2006/07/08/introducing-the-dapper-commercial-repository/ if you want [Opera] or RealPlayer and probably more coming.

35 !! Missing Functionality
21 CraigBox 36
37 http://ubuntuguide.org/ has all you need to know.
38
39 At our last installfest, we wrote an UbuntuPostInstall shell script for installing things such as:
40
17 DanielLawson 41 * media-related codecs (win32codecs/gstreamer-ffmpeg for WMV support, [DVD] CSS)
42 * [Java] runtime
43 * Flash and Adobe Acrobat Reader browser plugins
44
25 AristotlePagaltzis 45 It has mostly been made out of date by [EasyUbuntu | http://easyubuntu.freecontrib.org/].

47 !!Skype doesn't work
48
49 Skype doesn't play nicely with the default sound setup in Ubuntu hoary as it uses the old style OSS methods and requires exclusive access to /dev/dsp. If you have a sound card that does hardware mixing things seem to be significantly nicer, but if you've stuck on something like an IBM T42 Laptop without hardware mixing you'll have problems. There are several solutions.
50
51 # Stop esd before starting skype
52 # Setup ALSA software mixing
53 Stopping esd before starting skype works perfectly, but has the rather large downside of not being able to conveniently listen to mp3's etc while you have skype running. I have found the second method to be the most reliable and convenient.
54
55 Follow the instructions in [this Ubuntu forums post|http://www.ubuntuforums.org/showthread.php?t=32063] to setup ALSA with dmix to provide software mixing support. Once you have done this you will be able to have both Skype and another application such as RhythmBox open at the same time, however only one of them will actually be able to generate sound at once, so.
56
57 __To Place a call__
58 * Pause RhythmBox
59 * Switch to Skype, place call
60 * Hang Up
61 * Play RhythmBox again, for some reason I often have to close RhythmBox before it will start playing again
62
63 __To Answer an incoming call__
64 * Pause RhythmBox
65 * Answer call, talk
66 * Hangup
67 * Play RhythmBox again, for some reason I often have to close RhythmBox before it will start playing again
68
69 Apart from having to close RhythmBox to get it to play again sometimes this solution seems to provide functionality equivalent to what you would expect to get with any other operating system.
70
71 __Other Solutions__
72
73 Google reveals a host of webpages that present other solutions for solving the Skype sound problems under Hoary (and other distributions). These seem to involve one of the following
74 # Replacing esound with [polypaudio|http://0pointer.de/lennart/projects/polypaudio/]
75 # Piping skype thorugh esddsp
76
77 I didn't find either of these methods to work successfully on my hardware.
78
79 !! Setting up wireless networking
80
81 If your wireless network uses no security, or WEP based security, then the standard network-monitor applet will do you just fine. If you want to use WPA or WPA2 security, then this applet won't help you very much.
82
83 You'll need to install the wpasupplicant package.
84
85 See WirelessNetworkSecurityNotes for more information on setting this up.
86
87 !! Other networking related issues
88
89 Ubuntu's network setup is identical to debian, refer to the debian pages for any tips regarding this.
90
91 If you use a laptop, you should install ifplugd(8), an interface event monitoring daemon. Configured properly, this will remove annoying boot delays while your distribution tries to dhcp an IP address on a non-connected network card.
92
93 !! Installing packages asks for verification
94
18 JohnMcPherson 95 Sometimes you may see the following query when installing a package:
96 <verbatim>
97 Install these packages without verification [y/N]?
98 </verbatim>
17 DanielLawson 99
100 See AptNotes for some solutions
101
102 !! Installing the KDE desktop
103
104 As of Breezy, you don't need to have universe on to install KDE. You can simply "apt-get install kde" and you will have a functioning desktop. For a bit more, you can "apt-get install kubuntu-desktop" for a full Kubuntu desktop, including things like Amarok and Konversation not included in a default KDE install.
105
106 This will fill your Gnome menus with messy KDE apps, but you can get rid of these by running the following:
107
108 <verbatim>
109 sudo sed -i '/OnlyShowIn=/d;$a\OnlyShowIn=KDE;' \
110 /usr/share/applications/kde/*.desktop
20 MatthiasDallmeier 111 </verbatim>
112
113 !! Make Ubuntu clear the screen on console logout (like Fedora Core)
114
115 <verbatim>
116 echo "clear" >> ~/.bash_logout
17 DanielLawson 117 </verbatim>
24 StuartYeates 118
119 !! Reinstall all packages
120
121 There are times when you've damaged your install and but you'd rather rescue the system rather than doing a backup, reinstall and restore of local data. The following script will reinstall the overwhelming majority of packages on your system. Note that it will not fix broken/missing config files and may change the order of entries in grub.
122
123 <verbatim>
124 for pkg in `dpkg --get-selections | awk '{if ($2 == "install") print $1}'`;
125 do
126 apt-get -y --reinstall install $pkg;
127 done
128 </verbatim>
129
130 You will, of course, need to be root to reinstall all packages on your ubuntu system

132 !! My NICs swap order and this displeases me! :flasheyes:
