When I upgraded to 11.04, I stuck with the Ubuntu Classic desktop. With 11.10, that didn’t look feasible anymore, so I bit the bullet to try and learn to cope with Unity.

After the install, my first issues were:

1. How to add a program to the Dash, specifically rxvt

I use the terminal a lot, and I want something light, fast, and that doesn’t mess with my hotkeys (GNOME Terminal uses the Alt key for itself).

2. How to launch more than one rxvt with the Dash.

Many programs have a way to launch new windows or documents, but rxvt doesn’t and I’m sure I’ll come across others as well.

3. How to switch between multiple windows open in Chrome or other software.

Without the mouse that is.

4. How to make it faster.

I’m using a 2.6ghz quad core system (Opteron 2218s) with 4 gigs of ram and a NVidia 9400GT and while this isn’t the latest and greatest it should not crawl without a darn good reason.

And the answers turned out to be:

1. Make a .desktop file

In /usr/share/applications, create rxvt.desktop with these contents:

[Desktop Entry]
Name=RXVT
Comment=terminal emulator for the X window system
Exec=rxvt -rv -sl 2000
Terminal=false
Type=Application
Encoding=UTF-8
Icon=utilities-terminal
Categories=System;TerminalEmulator;
X-Desktop-File-Install-Version=0.18

Then chown the file to root:root with permissions -rw-r–r–.

2. Middle click on the icon in the Dash
3. Alt + ` (backtick)

Just like a Mac. Obviously, I didn’t try to guess hard enough before resorting to Google.

4. Switch to Unity 2D

Unity 2D is based on Qt and is meant for older machines with inadequate video cards. It is shocking to think that I have either, but it made a large difference. Besides, every time I’ve tried a compositing desktop before, I’ve had problems with other OpenGL programs, so I probably would have made the switch anyway.

At some point, my Ubuntu desktop started using NFSv4 to connect to my Solaris file server.
The visible symptom caused by this switch was all files showing up as owned by 4294967294:4294967294.

The fix turned out to be to edit the file /etc/default/nfs-common to change:
NEED_STATD=
to:
NEED_STATD=”no”
and:
NEED_IDMAPD=
to:
NEED_IDMAPD=”yes”

Also, change the Domain= line in /etc/idmapd.conf to match your networks domain line.

Then reset idmapd
sudo restart idmapd
