I may not have been clear about this in the previous post.

Pressing the "Frame" button has no effect on the screen. Does it need some special configuration to work?

No.
Check the  /home/olpc/.xbindkeysrc file. Somewhere towards the end should say

Code:

"toggle_color.sh"
 c:147

If not add the lines and reboot to take effect. If it does, check that the  /usr/bin/toggle_color.sh file. It should look like this

Code:

#!/bin/bash
j=0
read i < /sys/devices/platform/dcon/output
if [ "$i" == "0" ]
  then
    j=1
  fi

echo "$j" > /sys/devices/platform/dcon/output

If ok check that you do not have a stuck key.
To check if is the key in the terminal type

Code:

echo "1" >  /sys/devices/platform/dcon/output

to get the B&W screen and

Code:

echo "0" >  /sys/devices/platform/dcon/output

to go back to color. Or run the script from the terminal by typing

Code:

toggle_color.sh

I decided to create the swap file on the USB thumb drive.  I realize that that is another solid state device, but I feel it is a less critical one.  After enabling the swap file, I do think I've noticed reduced application latency, although it's hard to be sure.  One thing I would like to be able to do is add hooks to the device detection mechanism that automatically turns swap on when the USB drive is plugged in, and turns the swap off before unmounting the USB drive.  I think this would involve two things:

• Interfacing with the subsystem that detects and mounts devices
• Adding the swap activation and deactivation commands to the sudoers file as commands that can be executed without a password

I'm not horribly familiar with either of those mechanisms, so if anyone wanted to work with me on that (or point me to some documentation), it could be fun.

That sounds like a job for halevt. Its a daemon that executes arbitrary commands upon hal-detected events, i.e. when a device is physically connected or disconnected. It is mostly used to automount usb drives for users who want something really lightweight ( those not using a desktop environment like gnome, kde, or xfce (awesome users for instance). I just discovered it myself so i can't give alot of specific info but it seems like you could use halevt to execute swapon when your usb drive is connected and swapoff when disconnected.

I just attempted to install Teapot's Intrepid build.

I got as far as the reboot step, and got the error message:

KERNEL PANIC - NOT SYNCING: VFS: UNABLE TO MOUNT ROOT FS ON UNKNOW-BLOCK(0,0)

I am indeed using an SD card, so if anyone has any other advice, I'd appreciate it.

To Teapot who made Ubunto on the XO work and Mavrothal and the others who have done so much to support it, THANK YOU, THANK YOU, THANK YOU!  You have turned a nearly useless (to me) "toy" into an extremely capable and very useful device.

I first ran across the http://wiki.laptop.org/go/Ubuntu_Intrepid_for_the_XO page several months ago but (as a linux noob) I was daunted by the vast and rambling forum thread discussing installation.  I noted at the time a cry for help buried at the bottom of the wiki page, asking for somebody to put together a summary of the instructions as "nobody should have to read a 30+ forum thread just to make sure they're installing it right."  That told me I wasn't alone in wanting to try Ubuntu on the XO but feeling out of my depth to even get started.  But, having played around a bit recently with Ubuntu and OpenSUSE on an old Dell laptop, I figured I had nothing to lose but time in digging through the posts to try and figure this out.

Having spent a few days doing just that, I wanted to try and help other potential Intrepid users who were overwhelmed by the size of the forum thread.  I took the posted installation instructions, along with some important updates, extras and fixes, reorganized it a bit, and added it to the wiki.  I'd appreciate it if some of the more knowledgeable users review the wiki post to ensure I haven't messed anything up.  I do intend to continue following this thread to keep the wiki current and flesh it out with additional information. as needed.

Robo ... where did you add it to the wiki?

[RoboRay]

Hmm... I just checked it on a different computer and it's not there, but it does show up on the one from which I added it.  My changes are visible under Edit History, although they aren't showing up on the main page.

I guess they run a strange wiki.  I'll try to figure it out.

I found the problem. I had created a new user, and I was logged in as that user, who was not a member of group video. When I added the user to group video everything worked.

Thanks.

If you did it more that once and you follow EXACTLY the instructions try to give as many details as possible of what you did, eg in what machine, cards, all the steps, etc. Tell us if any messages appeared during the installation process.
As you can see this is not a common problem... so try to give enough details of what you did so someone may reproduce it(!!!)
My first guess would be some problem with the SDcard formatting.

[grey-haired-xo-user]

hello all! first of all thank you very much for teapots ubuntu and all the support. its an amazing little system and great for my first linux steps.

i encountered a problem though:
 after logging in, the xfce4-panels had disappeared.
they were only small grey stripes in the upper left corner. i right clicked one of those, and set all the preferences again, but it is not like the original anymore. (no firefox-icon above,no networkmanager on the bottom right..)

1. how do i reset the xfce4 panels back to its original states?

2. is there a way to disable wireless networking on startup?

(and, if you find the time:)

3. how do i stretch fullscreen games like NetPanzer to actual fullscreen?

thanks so much in advance,
Horst

1. how do i reset the xfce4 panels back to its original states?

If they are ersed they are gone... You can only reinstall from the original or remake them (right click-> add to panel.)

2. is there a way to disable wireless networking on startup?

(and, if you find the time:)

Menu->Settings->Startup applications

3. how do i stretch fullscreen games like NetPanzer to actual fullscreen?

You don't. Teapot's version does not support multiple screen resolutions.

[RoboRay]

Ok, it looks like the additions I made to the http://wiki.laptop.org/go/Ubuntu_Intrepid_for_the_XO wiki are finally showing up correctly.  I would still appreciate it if somebody with more linux and OLPC knowledge than myself reviews the wiki to make sure I didn't screw anything up.

[Adrienne]

If you did it more that once

I skipped the vital step of trying the reboot again. Thanks for the help.

Is the link to the torrent file for olpc intrepid working?

http://mars.illtel.denver.co.us/~abelits/torrents/OLPCFiles-intrepid-20081130.tar.bz2.torrent

I get a error message when I try to get the torrent, I've been able to use this link a few times before successfully, does anyone else have a alternative?

It would appear that the server (mars.illtel.denver.co.us) is down. Let's hope that is a temporary problem and teapot did not give it up altogether...
Give it a day first and then let's consider plan B (people with the original files may put them up elsewhere)

[RoboRay]

I've got the original file, as do others, no doubt.  I'm sure we can get a new torrent up and running pretty quickly, even if Teapot isn't available to do it.

That said, if we do have to create a new torrent, this might be a good time to roll in some updates, like Firefox 3.5 and some of the various little fixes and tweaks that have come along.
