Karl L. Posted August 25, 2013 Share Posted August 25, 2013 I bought a used Samsung Series 3 Chromebook (AKA the 2012 Samsung ARM Chromebook) about 3 weeks ago and have spent the majority of my free time since then trying to replace Chrome OS with Debian on the internal SSD. Although there is already a guide on the Debian wiki for almost this exact purpose, it makes use of binary blobs from Chrome OS and does not discuss replacing Chrome OS, only installing Debian on an SD card. That method works - and I used it verbatim to bootstrap my installation on the internal SSD - but as the author of the page admits it relies on unpackaged software with no source code available, which will potentially make the system difficult to maintain. Therefore I created a repository and packaged all of the required software not already in the Debian archive from upstream sources. I also wrote a few utilities of my own, which I also packaged and pushed to my repository, to fill in gaps in functionality not already covered by existing software. The result is a full installation of Debian Jessie (armhf) with the XFCE desktop environment and entirely packaged free software supporting it (with the exception of the proprietary Mali GLES library required for hardware graphics acceleration, which is packaged but obviously not DFSG free).Anyone else who has this hardware is welcome to make use of my rough installation guide below. If you find any bugs in my packages, have suggestions for improvements, or would like me to clarify something, please let me know in this thread. Although I can't promise that I will maintain this repository indefinitely, I always archive copies of software I write and package. Therefore if my repository is down or no longer contains some of the software referenced in this guide, feel free to PM me and I will try to offer a resolution. Without further ado, I present a rough guide for:Replacing Chrome OS with Debian Jessie on the Samsung Series 3 ChromebookThe Right Way 1. Follow the "InstallingDebianOn Samsung ARMChromebook" guide on the Debian wiki to install Jessie on an SD card or flash drive. This external image will in turn be used to install Jessie on the Chromebook's internal SSD. 2. Boot from the Debian installation you just created (Ctrl+U), and bootstrap the installation on the SSD. 2.1. Format ROOT-A (/dev/mmcblk0p3) as EXT4. mkfs.ext4 /dev/mmcblk0p3 2.2. Format STATE (/dev/mmcblk0p1) as SWAP. mkswap /dev/mmcblk0p1 2.3. Use gdisk to shrink STATE to 2147 MB (Start: 13.6 GB; End: 15.7 GB). The necessary procedure is explained in this tutorial. 2.4. Use gdisk to expand ROOT-A to 11.3 GB (Start: 2292 MB; End: 13.6 GB). gdisk /dev/mmcblk0 # Delete the partition and create it again with the desired size. # You are required to know how to do this in gdisk. # If you do not, read the tutorial linked in the previous step. resize2fs /dev/mmcblk0p3 2.5. Use cgpt to mirror the Chrome OS priorities for the partitions. cgpt show /dev/mmcblk0 cgpt add -i 2 -S 1 -T 15 -P 15 /dev/mmcblk0 cgpt add -i 4 -S 1 -T 15 -P 0 /dev/mmcblk0 cgpt add -i 6 -S 1 -T 15 -P 0 /dev/mmcblk0 cgpt add -i 1 -t data -l "STATE" /dev/mmcblk0 cgpt add -i 2 -t kernel -l "KERN-A" /dev/mmcblk0 cgpt add -i 3 -t rootfs -l "ROOT-A" /dev/mmcblk0 sync 2.6. Install Debian Jessie on ROOT-A. mkdir /mnt/rar mount /dev/mmcblk0p3 /mnt/rar -o rw,discard debootstrap --arch=armhf jessie /mnt/rar http://ftp.us.debian.org/debian nano /mnt/rar/etc/fstab # /etc/fstab: static file system information. # # Use 'blkid' to print the universally unique identifier for a # device; this may be used with UUID= as a more robust way to name devices # that works even if disks are added and removed.

mr_gigabyte Posted October 14, 2013 Share Posted October 14, 2013 a there are some missing links but most important is the debian link https://wiki.debian.org/InstallingDebianOn/Samsung/ARMChromebook gives an error on jessie.. Nonethe less, Im willing to try this using my current arch build but Im a bit confused on your partition for mmcblk0, are all the partitions 1-6? Because I, staring at 12 on mine..

Karl L. Posted October 14, 2013 Author Share Posted October 14, 2013 a there are some missing links but most important is the debian link https://wiki.debian.org/InstallingDebianOn/Samsung/ARMChromebook gives an error on jessie.. How so? I clicked every link in my guide a few minutes ago, and they are all still active. Although the guide on the Debian wiki has been updated slightly since I posted this tutorial, it still looks intact. I admit that I didn't follow the guide exactly the first time I used it (mostly because I installed Jessie on a flash drive instead of an SD card), but my deviation was slight. I have no reason to believe it doesn't work as-is. Nonethe less, Im willing to try this using my current arch build but Im a bit confused on your partition for mmcblk0, are all the partitions 1-6? Because I, staring at 12 on mine.. You are correct. There are twelve partitions. However, it is not necessary to use all of them for this procedure to work. On the contrary, I would prefer to start with a clean partition table and create only the partitions we absolutely need (which is technically four - firmware, kernel, boot, and root). However the Chromebook's firmware assumes the factory partition layout on the internal disk, and it would be far more effort than it's worth to install modified firmware to change that assumption, in my opinion. Therefore my guide instructs you to repurpose the existing partitions and set the appropriate flags to notify the firmware of the nominal changes (from its perspective).

Ignacio Posted October 18, 2013 Share Posted October 18, 2013 You're guidelines seems SO interesting that I'm ready to replace ChromeOS with debian. However, the link for the tutorial on gdisk seems to be broken. I've never used gdisk and I'm a little afraid of messing things up on the chromebook's ssd. From what I've read on the web, it seems that I have to delete the partition and create it again. Could you be so kind and explain that procedure a little further?

Karl L. Posted October 19, 2013 Author Share Posted October 19, 2013 You're guidelines seems SO interesting that I'm ready to replace ChromeOS with debian. However, the link for the tutorial on gdisk seems to be broken. I've never used gdisk and I'm a little afraid of messing things up on the chromebook's ssd. From what I've read on the web, it seems that I have to delete the partition and create it again. Could you be so kind and explain that procedure a little further? I fixed the broken link you pointed out, but after taking another look at the tutorial, I decided it would probably be a good idea for me to elaborate anyway. After all, partition and filesystem manipulation can be a little scary, even for those of us with more experience, so it doesn't hurt to be thorough. My instructions below correspond roughly to sections 2.1-2.5 in my opening post. I included a few extra commands which don't modify the procedure in any way, but should give you a better understanding of what is actually happening. Also note that I generated the output you see below in a virtual machine (in the interest of not reformatting my Chromebook again just for the purposes of this tutorial) using a virtual hard disk imaged with the Chrome OS recovery image for my Chromebook. Therefore while the partition table should be reasonably similar to one on an actual Chromebook, don't take it as canonical. Without further ado, every command I entered to modify the partition table and filesystem (in order), along with their unabridged output, is below. root@T1008:~# gdisk -l /dev/mmcblk0 GPT fdisk (gdisk) version 0.8.5 Partition table scan: MBR: protective BSD: not present APM: not present GPT: present Found valid GPT with protective MBR; using GPT.

Ignacio Posted October 20, 2013 Share Posted October 20, 2013 Thanks so much for your response. I'm going to try it tomorrow after work. If you don't mind, let me ask you about Flash: I've read many posts on how to make it work with Chromium and PepperFlash from ChromeOS. Have you had the chance to try it? TIA, Ignacio Link to comment https://www.neowin.net/forum/topic/1173005-replacing-chrome-os-with-debian-jessie-on-the-samsung-series-3-chromebook/#findComment-596038209 Share on other sites More sharing options...
Karl L. Posted October 20, 2013 Author Share Posted October 20, 2013 I do not use Flash anymore, even on i386 and AMD64. Therefore I have not tested it on my Chromebook under Debian. However from what I understand, you should be able to launch Chromium with the Pepper Flash Player plugin, like you suggest, without too much effort. You will need a copy of /opt/google/chrome/pepper/libpepflashplayer.so and /opt/google/chrome/pepper/pepper-flash.info from your original Chrome OS installation to make this work. If you don't have that installation anymore (presumably because you replaced it with Debian), you can also extract the files you need from the recovery image.

Ignacio Posted October 22, 2013 Share Posted October 22, 2013 Hi there. I'm right now in the middle of the installation but I'm presented with this error: xserver-xorg-video-armsoc : Depende: xorg-video-abi-12 pero no es instalable It looks like there's a dependency on one of your packages on a missing package in debian Any sugggestions? TIA, Ignacio Link to comment https://www.neowin.net/forum/topic/1173005-replacing-chrome-os-with-debian-jessie-on-the-samsung-series-3-chromebook/#findComment-596044051 Share on other sites More sharing options...
Ignacio Posted October 23, 2013 Share Posted October 23, 2013 First try installing was almost perfect. Besides the problem with the missing dependency mentioned in my previous post, I could install Debian. However, after booting up the computer I got a message in post saying that the ChromeOS was missing and I needed to reinstall it using my backup. I'm going to give it another try shortly. Since my partition layout was different than yours I could not follow your instructions as you suggested. I could not recreate p3 as you instructed and I could not do a resizefs on p3. May that be the reason why the computer is complaining at boot-time? TIA, Ignacio Link to comment https://www.neowin.net/forum/topic/1173005-replacing-chrome-os-with-debian-jessie-on-the-samsung-series-3-chromebook/#findComment-596045081 Share on other sites More sharing options...
Ignacio Posted October 23, 2013 Share Posted October 23, 2013 After restoring ChromeOS to its original state, I could follow your instructions and install it following your guidelines. I download installed from your repo the armsoc xorg driver using dpkg -i --force-depends, but I can't make X work. The log says: module ABI major version (12) doesn't match the server's version (14) Any help, please?

Karl L. Posted October 24, 2013 Author Share Posted October 24, 2013 After restoring ChromeOS to its original state, I could follow your instructions and install it following your guidelines.

The log says: module ABI major version (12) doesn't match the server's version (14) Any help, please? TIA, Ignacio The X server in Jessie has been updated since I built that package. The Xorg ABI changes with every major release, so each driver built against it needs to be updated every time the Xorg core is updated to a major new version. I just updated xf86-video-armsoc (which builds the xserver-xorg-video-armsoc binary package) to the latest upstream version, patched it for the XServer 1.14 ABI, built new binaries, and uploaded it to my repository. You should be able to install the package now. Let me know if you run into any other such regressions.

Ignacio Posted October 24, 2013 Share Posted October 24, 2013 I have applied your update, and it works now. Do you think it would be wise to put the xserver packages on hold to prevent updates unless there's and update on your driver? I believe there's a way to create binary dependencies in deb packages so, in this case, if they were declared in your driver, no updates to xserver would be applies until there's a new version of your driver. I haven't done that, but I could investigate it for you if you want. Thanks so much for your great work.

Ignacio Posted October 24, 2013 Share Posted October 24, 2013 First thing I noticed after login is that there seems to be no HW accelerated graphics. Playing video is quite painful, I haven't even tried setting pepperflash. Are you running it under the same conditions?

Xorg 1.15 will not be released, not to mention packaged, until early next year, and X receives security updates often enough to make unequivocally sticking with an older version potentially dangerous. I will update xf86-video-armsoc again when new versions of X are released. Although I had to make some minor code changes which have not yet landed upstream in this case, next time it will likely be as simple as recompiling the driver against the new Xorg ABI. APT (apt-get, aptitude, or your other front-end of choice) will give you the option to either remove the broken driver or stay upgrading the X server until the conflict is resolved when Xorg 1.15 is eventually pushed to Jessie. Therefore you can avoid breaking X at that point by not upgrading it for a few days until I upload the new driver and the conflict is automatically resolved. First thing I noticed after login is that there seems to be no HW accelerated graphics. Playing video is quite painful, I haven't even tried setting pepperflash. Are you running it under the same conditions? Thanks, Ignacio Graphics are accelerated, but you only have partial 3D acceleration. Unfortunately there is no support for the Mali T604 in Mesa, and ARM's proprietary DRI library (at least the one that ships with the Chromebook) only partially supports 3D acceleration. Chrome OS works around this limitation by drawing everything in an OpenGL window using the completely functional OpenGLES acceleration. If you are interested in more details, read Ubuntu Bug #1085596.

Karl L. Posted October 24, 2013 Author Share Posted October 24, 2013 Or just save yourself the hassle and get "Chrubuntu" :) Although ChrUbuntu is an easy way to install Ubuntu natively on a Chromebook, it is not equivalent to my method. The principal difference is that ChrUbuntu is designed to install Ubuntu onto an external device (such as a flash drive or an SD card) so it can be dual-booted with Chrome OS, whereas my tutorial details how to install Debian (although it could just as easily be applied to Ubuntu) to the Chromebook's internal SSD, completely replacing Chrome OS. As far as I know, the tutorial I posted in the opening post is the only one of its kind. The method is not particularly easy, and could probably be automated similarly to ChrUbuntu. Therefore it is not intended for the casual user. Its primary advantage is that the OS will run much faster from the internal SSD than from a flash drive or SD card. However, like you noted, there are some serious downsides to consider.

Karl L. Posted November 17, 2013 Author Share Posted November 17, 2013 hi xorangekiller i have a problem with a "wget -q https://dl.dropboxusercontent.com/u/62647756/repos/apt/debian/keys/xorangekiller.asc -o- | apt-key add -" line i get "gpg: no valid OpenPGP data found" !! The GPG key I use to sign my repository has not changed, nor has its location relative to the repository. However, I notice that the command you quoted is not the same as the one that appears in my tutorial. You replaced the uppercase "O" at the end of the wget command line with a lowercase "o". Since wget options are case-sensitive, as is true of most utilities, it is not surprising that the command you quoted does not work. You are told that there is no OpenPGP data to be found because that is exactly the case. Try the following command (which is the same as the one which appears in the tutorial in my opening post) instead. # wget -q https://dl.dropboxusercontent.com/u/62647756/repos/apt/debian/keys/xorangekiller.asc -O- | apt-key add - i've try gpg --import xorangekiller.asc and it seemed to work but I get errors during apt-get update Although you successfully imported my public key into your GPG keyring using gpg --import, that is not relevant to APT. APT keeps its own keys in /etc/apt/trusted.gpg and /etc/apt/trusted.gpg.d. Therefore apt-get is not able to verify the signing key of my repository in your case because APT does not have my public key. If you wanted to isolate downloading the key and adding it to your APT keyring into separate commands, you could do so as follows: $ wget https://dl.dropboxusercontent.com/u/62647756/repos/apt/debian/keys/xorangekiller.asc # apt-key add xorangekiller.asc $ rm xorangekiller.asc Link to comment https://www.neowin.net/forum/topic/1173005-replacing-chrome-os-with-debian-jessie-on-the-samsung-series-3-chromebook/#findComment-596108175 Share on other sites More sharing options...
vlotho Posted November 18, 2013 Share Posted November 18, 2013 actually, I had not thought about the capital o :) . the key is imported. at the end of the command it says "ok", by cons in the update, I still have errors on the deposit "unstable".

Karl L. Posted November 18, 2013 Author Share Posted November 18, 2013 It sounds like apt-key added the repo key to your APT keyring this time. The only thing it is supposed to print after a key has been successfully imported is "OK". That said, I have absolutely no idea how to interpret you new problem. I will try to help you, but you need to be precise! Based on the resolution of your last issue, my advice is to double-check that you typed everything correctly. This is Linux. Case matters. Spacing matters. My guide has been tested numerous time. It is unlikely that it has any major flaws in its current incarnation. (Although software is revved, and I am only human; so I'm not so foolish as to claim my guide is absolutely bulletproof.)
