Are you guys booting with the persistence option ?

Thanks for all the email and host links guys !! I'll reply to you all tomorrow as its very late now and I need to get some sleep

Yep did everything like I did in the last version.. even did it 2 times to make sure I was doing it right.  Not sure what the problem is.

Aside from that, I love the changes you've made.

If you can create a bit for bit image file of an 8gb partitioned persistent stick running .2b, that would make a lot of people's lives a lot easier. The persistence doesn't work, even after modifying syslinux.cfg in the windows readable portion of the stick. In .2b there's no /media/x09sd9fj to unmount.

Is it possible to instead create a bin or img file that can be written bit for bit to an equally partitioned usb stick? There are sure to be a few windows based programs that allow for bit level cloning ala ghost.

I'll pay you or anyone else $50 for this tutorial/image file via paypal. I want to see LinuxCoin own.

I've just tested and persistence works fine ?



/dev/sr0 is my CD rom and /dev/sda1 is a quick harddisk I created in vmware and formatted to ext4 labeling live-rw

Follow the guide until you get to boot from linuxcoin. Next open up a root terminal and type

Code:

fdisk /dev/sd*

* = your HDD number. If you don't know what it is then type

Code:

df

And look for what drive is mounted as /live/image. That's the one you want.

next type

Code:

mkfs.ext4 -L live-rw /dev/sd*2

and wait for it to complete.

Then reboot and select LinuxCoin persistent and your golden

Getting a bunch of "deprecation warning" messages using phoenix, linuxcoin 0.2b ?

Seems to be just when I start it up?

'enqueue_read_buffer' has been deprecated in version 2011.1. Please use enqueue_copy() instead.

[drgr33n]

EDIT: Even easier way to use persistence on the way !! Literally just drop a file onto your flash media and your golden

Files are being uploaded now I'll link em when they are complete. Might take a while though because they total 3.5GB and I'm on a 3G connection.

I've tested and they work great !!

Thats due to pyopencl being updated to the latest version. It's nothing to worry about and really should be taken up with the author of phoenix

What is the problem? you make 2 partitions, one fat32 and put the linuxcoin image on it with unetbootin. The second, leave as free space. boot in default mode, follow the "old" guide..

if you have /dev/sda1 as the linuxcoin partition:

fdisk /dev/sda
n
p
2
enter
enter
w

shutdown, restart choosing persistent mode

mkfs.ext4 /dev/sda2 -L live-rw
enter
enter

sudo df

you should see:
/dev/sda1 ... /live/image
/dev/sda2 ... /live/cow

now shutdown, plug the usb stick into your pc and edit /live/image/syslinux.cfg and put the last 2 lines under persistent where the last 2 lines for default were. now it will be persistent mode by default

If you want persistence to be larger than 2GB follow this if not just format the whole flash media as fat32 and install with unetbootin and then download a virtual hdd from the links in the first post and extract it onto the root of your flash media (when all the ubn files are )

This is exactly what I have now too with v0.2b and I have not checked yet if I have persistence or not, I just mine for now and if I encounter the urgent need to have persistency, I will bother someone again.
The only real gain I had with persistence enabled was that it remembered the background and font color of the root terminal, and in v0.2b these settings are back to black/white again so if I have to reboot ever, I don't have to do any settings, all is setup for me, thanks to Gr33n 

So if you don't get persistence working, ask yourself: do I need it? Is all the effort that goes into making it work worth the time that you are now not mining? What settings is it remembering that you really need?

I just go to /opt/miners/phoenix and then run the miner, then I click AMDOverclockCtrl tool and set my clocks.
All done, nothing to do here for weeks. Until next LinuxCoin version comes out

Hi,

A Linux/LinuxCoin newbie here and just started installing LinuxCoin yesterday.

I have the same problem as some people here that version 2.0b does not work.

I have installed 2.0a by following the instructions and I am able to run with persistent.
Then I have another flash drive installed 2.0b and boot again with this newly created flash drive. I am not sure if I have persistent or not (I chose that option), but all the software are 2.0b version now

Another question:

I was running windows 7 64bit before. Now, it won't allow me to boot up windows again. When it boots, it give me some error message saying something like system file error, and the only way I can boot is using LinuxCoin now. Need some advice on how to boot up windows.

Thx!

This works fine - can't get to edit syslinux.cfg in root mode as to allow saved changes, though.  Any Ideas?

Hi drgr33n,

starting screen in 0.2b gives

user@linuxcoin:~$ screen
Directory '/var/run/screen' must have mode 777.

this is on a usb key after enabling persistence (and removing kexec and that annoying read x < /dev/console inside /etc/init.d/live-boot.sh)

best regards.

Whoops look like you may of wrote to the wrong disk bud in no way does Linuxcoin touch your hdd. Load up Linuxcoin and post the results of typing the following into a root terminal.

Code:

df -h
Fdisk /dev/sda
p
q

And I'll help you out more.

[drgr33n]

Forget the old tutorials guys and read the first post again. It's as simple as 123 to install Linuxcoin with persistence. No os swap no two partitions. Just format your drive as fat32 forget about partitions. Download a filesystem image from the link in the first post and extract it to your flash media. Reboot and select Linuxcoin persistent.

You don't need to edit syslinux and you dont need to get technical lol just use the image files unless you are comfortable with using Linux to format your partitions. I worked hard getting this right so you didn't have to mess about and get your hands dirty

Dang you can fix by changing the permissions on that file for now.

Code:

chmod 777 /var/run/screen 

To the second issue ?? I may be being thick to lack of sleep but I didn't get what annoying thing ?

[TheVirus]

Booted to .2b and tried to login, it fails. I tried user/live, user/user, live/live, live/user. Nothing works, neither on the main login window or a different TTY.

Edit: Rebooted to Default and then again into Persistent mode and it brought me to a desktop. Not sure what happened.

drgr33n,

if you want to be able to reboot a rig from remote and be sure that it is fully re-initialized (maybe because you find it hanged with a kernel trap), you need to:

- remove from /etc/init.d/live-boot the request that reads "remove USB key and press enter to reboot", this is the annoying thing and to accomplish this you have to remove the line "read x < /dev/console" which is the command that stops the re-boot waiting for a key

- change /etc/default/kexec where it says: LOAD_KEXEC=true, put false instead, so that you always do a cold reboot. A sudo coldreboot does the same thing, but if you're remote and issue a sudo reboot for error... dang, system locked


BTW, is Catalyst 11.6 installed?

New issue: Running in persistent mode and enabled encryption on the user's home directory. I also changed the auto-login script in inittab. I rebooted and was prompted with the desktop with the missing background/menu items. It seems to have auto-logged in as the user. I logged out and logged back in as the user using my own password, so far so good. I checked TTY1 and saw that the root user is logged in. Furthermore, the user is logged in on other terminals.

This isn't very secure if root auto-logs in at reboot. Kind of defeats the purpose of having a user.

[spiccioli]

drgr33n,

btw, a

Code:

sudo chown -R user:user /opt/miners

and

Code:

sudo chmod 777 /opt/miners/phoenix/*.py

needs to be issued to be able to run phoenix, at least, I don't know if the other miners need this too, but it should not pose any harm.

Ok makes sense I'll probably revise this iso as I think
I rushed a little to get it out and overlooked a couple of things.

Yes the catalyst is at 11.6 some report it working others say it doesn't. What cards ? And just checking but you did enable overdrive first right ?

New issue: Running in persistent mode and enabled encryption on the user's home directory. I also changed the auto-login script in inittab. I rebooted and was prompted with the desktop with the missing background/menu items. It seems to have auto-logged in as the user. I logged out and logged back in as the user using my own password, so far so good. I checked TTY1 and saw that the root user is logged in. Furthermore, the user is logged in on other terminals.

This isn't very secure if root auto-logs in at reboot. Kind of defeats the purpose of having a user.

This is normal behaviour. When gdm auto logs in it actually uses a gdm account. That's why when you log back in you have no icons because gdm doesn't have permission to Access your home directory. And admins still logged in because you swiched to telinit 1 I assume. Doesn't matter root doesn't have a password and when you reboot if you disabled autologin you will be met with the login screen and root won't be logged in on any terminal. Well unless you open one

I would recommend creating a new account and dropping user all together.
