These things should probably be put up somewhere in the wiki.laptop.org site.

Getting to the virtual terminals:
ctrl+alt+fn+1 - takes you to virtual terminal 1 you can log in as root with no password
ctrl+alt+(third button from the top left is a circle of dots) - also takes you to the terminal 1
With the fn key you can use 2,3,4,5 or 6 instead of 1 to go to a different terminal (standard linux f1-f6)
You can also use the keys on the top of the keyboard moving right to left.
alt-0 toggle developer console

Getting back to the gui (sugar/x11)
ctrl+alt+fn+7
ctrl+alt+(5th dot from the left in the sequence of dots at the top of the keyboard)

You can mount a usb memory stick
go to to the virtual terminal
login as root
plug in the usb stick
make the /mnt/stick directory if it doesn't exist:

mkdir /mnt/stick

mount the usb device:

mount /dev/sda1 /mnt/stick

now you can cd to /mnt/stick to access the files on the usb stick
when you are done unmount it:

umount /mnt/stick

To make sure the usb stick is recognized

the first few times you will want to do the following to see if it works:

tail \-f /var/log/messages

then plugin your

Communication between the host and the emulator

QEmu(Q)

Redirect ssh port when running qemu. For example,

/Applications/Q.app/Contents/MacOS/i386-softmmu.app/Contents/MacOS/i386-softmmu -m 256 -redir tcp:2222::22 -hda /Users/skim/sk/proj/olpc/xo_images/olpc-redhat-stream-development-build-542-20070801_0412-devel_ext3.img

(The GUI front of Q doesn't seem to remember command line arguments)

Then ssh or scp onto that port:

ssh -o NoHostAuthenticationForLocalhost=yes -p 2222 root@localhost
 scp -o _sourcepath_ NoHostAuthenticationForLocalhost=yes -P 2222 root@localhost:_destpath_

Parallels

Use whatever ip address the virtual host has obtained, e.g., /sbin/dhclient eth0, for ssh and scp.

Parallels/Ubuntu

As of November 2007, Gutsy Gibbon didn't work. Install Feisty Fawn instead (with 512MB RAM).

If the window size of Sugar is too big, see http://wiki.laptop.org/go/Sugar_with_sugar-jhbuild
for instructions on modifying resolution/size.

xauth problem

Some recent builds keep restarting X with error message about client being rejected from server.
It can be circumvented by removing the line for .Xauthority from /etc/rwtab and deleting ~olpc/.Xauthority.
Better boot in devboard mode to get some time to edit between X convulsions.

Development

The development site (http://dev.laptop.org/) is a trac site where you can browse the source history.

Log files for Sugar are located under ~olpc/.sugar/default/logs.

Version issues

sugar-jhbuild, as of 11/11/2007, requires the following entries for activity.info:

• bundle_id
• name
• activity_version
• mime_types
• exec
• show_launcher
• icon

And sugar-activity-factory was replaced with sugar-launch.
It states in the code that service_name and class are deprecated for bundle_id and exec.

Yet as of redhat image build 623, sugar-install-bundle demands a service_name and class, and sugar-activity-factory exists
instead of sugar-launch.
