5.1   2007-05-06 how i activate xgl on my ubuntu laptop

doc source: https://help.ubuntu.com/community/CompositeManager/Xgl

• install package xserver-xgl, compiz (other dependent packages)

• add following to '/etc/gdm/gdm.conf-custom':

  [servers]
  0=Xgl #Override display 0 to use Xgl
  
  [server-Xgl]
  name=Xgl server
  command=/usr/bin/Xgl -fullscreen -br -accel xv:pbuffer -accel glx:pbuffer
  flexible=true
  

• according to information from source, the [servers] section should be '1=Xgl', but it doesn't work.

• 2007-05-06 install gnome-compiz-manager and click System -> Preferences -> GL Desktop

5.2   2008-01-10 Xgl frequently crashes

Xgl worked fine for a while after feisty was upgraded to gutsy. After a major update in gutsy, it started to crash quite frequently. googled online a bit. Found it's probably nvidia driver's fault. On the other hand, two packages for nvidia Xorg driver: nvidia-glx and nvidia-glx-new. Now it's using nvidia-glx-new. But nvidia-glx was installed before (now removed). So i installed nvidia-glx and removed nvidia-glx-new. (so far so good).

5.3   2008-01-11 enable remote display for Xgl server

• in gutsy, Xgl is behind gdm (display 1). gdm is using Xorg server (display 0). Modifying /etc/gdm/gdm.conf won't help.
• edit /etc/X11/Xsession.d/98xserver-xgl_start-server to remove "-nolisten tcp".
• Log out and login to reboot Xgl. then xhost/export DISPLAY="hostname:1" would work.

5.4   2008-01-24 Xgl slow down

Shift+F10 controls the speed of all animations. In System -> Preferences -> Advanced Desktop Effect Settings -> General Options -> Actions -> General -> Slow Animations.

2008-07-09 now this function is disabled by default.

5.5   2008-03-24 disable Xgl

edit /etc/X11/Xsession.d/98xserver-xgl_start-server, comment out XGL_START.

5.6   2008-03-24 enable remote display for gdm-backed X server

edit /etc/gdm/gdm.conf and change DisallowTCP=true to DisallowTCP=false.

7.1   2008-02-12 install subclipse for eclipse

eclipse has support for cvs built-in, but not svn. subclipse is a feature for eclipse to have svn support.

In eclipse, click 'help' -> 'Software Updates' -> 'Find and Install ...'.

Get the subclipse update URL from http://subclipse.tigris.org/ and add http://subclipse.tigris.org/update_1.2.x as a remote site to eclipse. Follow through and that's it.

7.2   2008-03-15 install Perl Eclipse feature.

update URL: http://e-p-i-c.sourceforge.net/updates/testing

7.3   2008-03-15 install astyle eclipse plugin.

add --indent=tab=4 in Other options of Preferences. update URL: http://astyleclipse.sourceforge.net/update

7.4   2008-03-16 install R eclipse plugin.

update URL: http://www.walware.de/eclipseupdates/. uncheck "Show the latest version of a feature only" as 0.4.x requires eclipse 3.3.

2009-4-19 new update site: http://download.walware.de/eclipse-3.4

7.5   2008-03-18 c/c++ plugin outline

The c/c++ plugin's Outline is a bit tricky to work out. Have to convert the whole project to c/c++ project to make use of it. It's tricky to find out how to convert. Right-click a project(or its folder), choose 'New', choose 'Other...', expand the 'C++' and you'll see 'Convert to a C/C++ Make Project'.

7.6   2008-03-21 Mylyn

update URL: http://download.eclipse.org/tools/mylyn/update-archive/2.0.0/e3.2 sudo eclipse to install it system-wide, not in your home directory.

7.7   2008-03-25 Eclipse SQL Explorer

The update site for Eclipse SQL Explorer is http://eclipsesql.sourceforge.net/

7.8   2008-04-24 Oribe XML

http://www.cumminsonline.com.ar/eclipse/xml/

download http://www.cumminsonline.com.ar/eclipse/xml/oribexml.zip, unzip, put the plugin in the eclipse plugins directory:

mv /tmp/plugins/ar.cba.oribe.xmled.OribeXmlPlugin_0.5.4/ /usr/lib/eclipse/plugins/

This XML editor has minimal setup and can't really edit files without 'xml' suffix.

7.9   2008-04-28 other XML editors

XML Buddy

oxygen XML Editor and XSLT Editor/Debugger http://www.oxygenxml.com/

Eclipse HTML Editor Plugin

7.10   2008-04-24 Web Tools Platform

http://www.eclipse.org/webtools/index.php

• download WTP link

• unzip

• put contents in features/ and plugins/ into eclipse directory:

  cp -r /tmp/eclipse/features/org.eclipse.wst* /usr/lib/eclipse/features/
  cp -r /tmp/eclipse/plugins/* /usr/lib/eclipse/plugins/
  

This package is supposed to have xml, html editors. But never figured out how to use it (didn't pop up).

7.11   2008-05-28 open a project related to a file system directory

Pick a "General" project, fill in the name and select the directory location. Don't pick "Pydev Project". It doesn't allow you to have a location where a directory already exists.

7.12   2008-05-30 eclipse vi/vim plugin

3 candiates (or more check http://vimplugin.org/history):

1. vimplugin http://vimplugin.org/
2. viPlugin http://satokar.com/viplugin/index.php
3. Eclim http://eclim.sourceforge.net/

viPlugin retains eclipse editor and have a toggle button to enter vi mode. but commands such as :g/abc/p don't work. auto-completion uses eclipse's shortcut 'alt+/'.

vimplugin has an old sourceforge website which google turned it up 1st and the tarball from its download link is buggy. it embeds gvim into eclipse.

vimplugin setup:

1. http://vimplugin.sf.net/update from http://vimplugin.org/ as the eclipse update site.
2. click Window -> Preferences -> Vimplugin:
   1. setup the path to gvim.
   2. click 'Embed Vim' (maybe not, this disables 'ctrl+n' auto-completion in vi).
   3. change Port if you have >1 eclipse's running

vimplugin problems:

1. Auto-completion screws up because 'Ctrl+n' opens the New wizard in eclipse while eclipse's 'Alt+/' has a different binding in gvim. Even after 'ctrl+n' is disabled in eclipse, 'ctrl+n' closes the embedded gvim. The un-embedded 'gvim' can solve this issue somehow.
2. word_complete plugin completes with palindrome letters.

7.13   2009-4-19 install python plugin for eclipse

7.14   2009-4-19 install eclipse 3.4 on ubuntu hardy

2. download the "Eclipse Classic 3.4.2"

3. move the unzipped directory to /opt/

4. download the eclipse log (used in gnome menu) into /opt/eclipse

5. create shell shortcut, /usr/local/bin/eclipse, to make eclipse visible in PATH:

   #!/bin/sh
   export ECLIPSE_HOME="/opt/eclipse"
   $ECLIPSE_HOME/eclipse $*
   

6. create gnome menu item, /usr/share/applications/eclipse.desktop:

   [Desktop Entry]
   Encoding=UTF-8
   Name=Eclipse
   Comment=Eclipse Ganymede IDE
   Exec=eclipse
   Icon=/opt/eclipse/ganymede.png
   Terminal=false

8.1   2008-03-03 skype

Comparison of VoIP software

Force to install the i386 skype debian package (amd64 machine) but /usr/lib32 doesn't have libXss.so.1 and other 4 Qt libraries.

So get the static version (linux 2.0 beta). But the libXss.so.1 is still needed (static-skype is not fully static). Copying libXss.so.1 from a 32bit debian/etch to /usr/lib32 solves the problem.

Video /dev/raw1394 is not recognized in this version. http://ubuntuforums.org/showthread.php?t=606790 has a possible solution. 2008-03-04 that forum thread refers to http://dv4l.berlios.de/ but it doesn't work.

8.2   2008-03-03 gizmo

download the deb from http://download.gizmoproject.com/GizmoDownload/gizmo-project_3.1.0.79_libstdc++6_i386.deb

force install by dpkg -i --force-architecture gizmo...deb due to amd64 on my machine.

The only problem is libsipphoneapi.so.1.7.07.73, which is installed into /usr/lib/. So sudo ln -s /usr/lib/libsipphoneapi.so.1.7.07.73 /usr/lib32/libsipphoneapi.so.1.7.07.73. Thanks to http://www.uluga.ubuntuforums.org/showthread.php?p=3253679

8.3   2008-03-03 globe7

force-architecture install the package from http://www.globe7.com/linuxsys.php

The main script /usr/bin/globe7 has certain issues, wrong paths, etc. Need to get lots of 32bit gnome libraries.
