[edit] Read Me First

This assumes you've yum installed IceWM.

[edit] Caveats

1. xterm is very, very hard to read.
2. Menus, labels, and text are oversized compared to the graphical elements of the UI.
3. I still can't find an easy way to select wireless networks.
4. $PATH appears not to be exported.

[edit] Workarounds

(Respectively)

1. Install a better terminal.
2. yum install control-center and tinker with the font sizes and/or dpi settings
3. When you log out of IceWM, select your wireless network through the Sugar UI, and then press ◆ ctrl + ◇ alt + erase to drop back into IceWM.

[edit] Procedure

Taken from the OpenBox instructions

su
cp /etc/skel/.xsession-example ~/.xsession
nano ~/.xsession

...and the lines reading...

# Uncomment the following line to debug sugar startup problems
#exec xterm

...should be followed by...

icewm-session

• Note: Use gnome-session if you prefer GNOME and provided you've yum groupinstall "GNOME Desktop Environmwnt" --skip-broken --exclude olpc-logos (yes, that's what I had to do to get GNOME installed).

Resist the temptation to uncomment the #exit 0, otherwise you won't be able to drop into Sugar when you need it.
