{{TOCright}} |
|||
This is a page for notes and test results for the http://dev.laptop.org/~cjb/rawhide-xo/ development builds. |
|||
== What is it? == |
|||
A "spin" of [[Fedora]] rawhide (the development version of Fedora 11 Linux) incorporating recent [[Linux]] software packages, the [[Sugar]] desktop UI ''and'' a more conventional Gnome desktop. |
|||
As such it is sort of a replacement for the cutting-edge [[joyride]] [[OS images]] that OLPC used to produce. See [[Future releases]] for the change in plans. |
|||
As such builds are very raw and often ''may not work at all''. |
|||
=== Build contents === |
|||
Each nightly Fedora Rawhide build e-mails a list of its packages and sends it to [https://www.redhat.com/archives/fedora-devel-list/ fedora-devel-list]. |
|||
Rawhide-XO is an adaptation of the nightly Fedora Rawhide. It uses kickstart files (see <tt>.ks</tt> files, see http://dev.laptop.org/git/projects/fedora-xo/tree/) to customize the build for the different images it provides. |
|||
== Resources == |
|||
* [http://dev.laptop.org/~cjb/rawhide-xo/ preliminary images] |
|||
* [http://dev.laptop.org/git/projects/fedora-xo/ sources] |
|||
* [https://www.redhat.com/archives/fedora-olpc-list/ mailing list] |
|||
* [irc://irc.freenode.net#fedora-olpc IRC] |
|||
== Installation == |
|||
The images page http://dev.laptop.org/~cjb/rawhide-xo/ has installation instructions. |
|||
=== USB/SD image installation === |
|||
The <tt>.bootable.gz</tt> image writes a partition table as well as the contents of a 2GiB partition to your USB or SD card. |
|||
It does this regardless of the actual size or previous partitioning of the memory card. |
|||
Note the card must be 2 Gibibytes, which is substantially bigger than 2,000,000,000 bytes; |
|||
many 2GB cards only store 1.91 x 1024 x 1024 bytes. |
|||
You can instead use the [http://fedorahosted.org/liveusb-creator/ Fedora LiveUSB Creator] to create a live USB or SD from one of the <tt>.iso</tt> files. |
|||
== Basic user guide == |
|||
On first boot at the login screen, you can choose either Gnome or Sugar from the drop-down list at the bottom. You want to login as "liveuser", or wait for automatic login. |
|||
=== Sugar === |
|||
If you start the Gnome desktop (the default), you need to exit to switch to Sugar. |
|||
(Sugar commands like <tt>sugar</tt> are available to you in Gnome, but running them under another desktop manager is '''not''' recommended.) |
|||
To return to the "first boot" login screen from Gnome, in Terminal, run [[su -l]] then run as [[root]]: |
|||
init 3 |
|||
log in as liveuser, then run as root |
|||
init 5 |
|||
it will stop GNOME and restart gdm |
|||
In the Sugar desktop, to set the keyboard to match the XO-1's keyboard, start [[Terminal Activity]] and enter |
|||
setxkbmap -model olpc |
|||
The AltGr key will now work to insert the special characters on some of the keycaps. |
|||
See [[Keyboard shortcuts]] for keys in Sugar (e.g. Alt+Shift+F brings up the Frame) |
|||
and http://en.flossmanuals.net/Sugar for general Sugar instructions. |
|||
=== Accessing NAND Flash === |
|||
If you boot rawhide-XO off USB or SD, the XO-1's internal 1GB of NAND flash storage is left unmounted. But this storage is available as the <tt>mtd0</tt> device. To make this accessible at the path <tt>/mnt/''my_nand''</tt> you could as [[root]] enter the command |
|||
mkdir /mnt/my_nand && mount -t jffs2 mtd0 /mnt/my_nand |
|||
== Differences from OLPC images == |
|||
''Many of these are probably shared with "Sugar on a Stick" SoaS-2 images, and should be on a common page.'' |
|||
* the default user is liveuser, not olpc |
|||
* liveuser can't use [[sudo]] to run commands as [[root]] (but can run [[su -l]] to become root). |
|||
* many olpc commands missing, such as olpc-netstatus |
|||
* different file system |
|||
** /efi instead of /ofw |
|||
** /home/liveuser instead of /home/olpc |
|||
== Known issues == |
|||
* On the XO-1, you must hold down the checkmark <nowiki>'</nowiki>'''√'''<nowiki>'</nowiki> gamepad key at boot, otherwise boot will hang with the XO guy on white. |
|||
* Keyboard map alert. |
|||
* Can't choose Gnome or Sugar after desktop login |
|||
* You can't choose an English or American OLPC keyboard in the keyboard chooser on the "first boot" login screen. |
|||
* No power management until you install [[Ohm]] |
|||
* The stock Fedora kernel does not play sound, hence (probably) why totem crashes. [https://www.redhat.com/archives/fedora-olpc-list/2009-March/msg00136.html how to replace with the OLPC kernel] |
|||
See [https://bugzilla.redhat.com/showdependencytree.cgi?id=461806&hide_resolved=1 Fedora on XO tracker bug dependency tree]. |
|||
Also see [[{{TALKPAGENAME}}]] for user reports, and [http://wiki.sugarlabs.org/go/Sugar_on_a_Stick/Getting_Involved/Testing Sugar Labs testing reports] for the similar SoaS-2 images. |
|||
=== Kernel differences === |
|||
The OLPC OS Images contained a customized kernel; its differences with the stock Fedora 11 kernel include: |
|||
* open firmware interface (arch/x86/kernel/ofw.[ch]) |
|||
* geode GPIO driver (used by DCON and suspend/resume) |
|||
* dcon driver (drivers/video/olpc_dcon.[ch]) |
|||
* suspend/resume code (arch/x86/kernel/olpc_pm.*) |
|||
* parts of the HGPK touchpad: drivers/input/mouse/olpc.c |
|||
* working sound drivers |
|||
== Reporting bugs == |
|||
* You should file bugs with the Sugar desktop and activities in the [http://dev.sugarlabs.org/ Sugar Labs bug tracker]. You can check with the sugar-devel list before or after. |
|||
* Bugs with the Fedora "rawhide" distribution and its behavior on the XO-1 should be filed in the [https://bugzilla.redhat.com Red Hat Bugzilla. You can check with the Fedora-OLPC list before or after. |
|||
:* product "Fedora", version "Rawhide", pick relevant component. |
|||
:* After creating your bug, edit it to add '''461806''' in the "Blocks" field to link it to the [https://bugzilla.redhat.com/show_bug.cgi?id=461806 FedoraOnXO tracker bug]. |
|||
: ''Note: the product "Fedora OLPC" is discontinued. Any bugs filed against this deceased product should be filed against Fedora if they are still valid.'' |
|||
== See also == |
|||
* [http://sugarlabs.org/go/Sugar_on_a_Stick Sugar on a Stick]. "SoaS 2" are similar development builds based on Fedora 11 ("Rawhide"). |
