Re: Running Debian in a chroot

No, just install KDE normally, in maemo, I think.

Yes, install KDE on your tablet from your tablet OS, then start KDE and chroot to Debian from KDE (from the KDE terminal) or make KDE desktop icons that run Debian chroot apps.

Re: Running Debian in a chroot

I'm confused again. I partitioned and formated my 4gb memory card that I keep in the internal slot of my N800, it is setup as follows.
/dev/mmcblk0p1 - fat, for general file storage
/dev/mmcblk0p2 - ext3, where I installed the large debain bootstrap. by quole

Now when I run the /sbin/debian script (as root) it fails from mounting /dev/mmcblk0p2 to the end. I did change that line in the script to match my partitions.
But
When I copy and paste each line from the script it works fine and I chroot into debian.

I'm totaly lost. Why will the script work when I paste it line by line but not when run? Yes I did chmod +x /sbin/debian.

Re: Running Debian in a chroot

If you have already mounted your partition, you will get an error about the mount failing, but that's a meaningless error (it has already mounted, it can't do it again), and the script should proceed normally. What errors are you getting after the failed mount?

Re: Running Debian in a chroot

I get the same weather it's munted or not

Code:

/home/user # debian

Setting up the chroot...

and it does not chroot.

here is the script, copied ffrom the wiki

Code:

echo "Setting up the chroot..."

export CHROOT=/opt

mount -o bind /proc $CHROOT/proc

###

# Actually chroot.

echo "Everything set up, running chroot..."

chroot $CHROOT $*

Re: Running Debian in a chroot

Ok, first thing to do is find those two kernel modules, mbcache.ko and ext2.ko. You might need to become root and then:

Code:

cd /

find . -name "mbcache.ko"

Wherever you find mbcache.ko, you'll probably find ext2.ko. Change the directory in those two insmod lines to match the directory where you found the modules. Then try it all again.

Also, the weird spacing in your error messages suggests that there may be something weird happening in the text file you made for the script. Did you use Windows to make the file? You might need to make it again in Linux. It would be best if you used a tablet editor like leafpad to do it.

Re: Running Debian in a chroot

I think I've got it fixed. qole, I did use notepad in Windoze, I was thinking about that on my way into work today (I hate M$). So I used leafpad and made a new debian script, that did not work, but the formating in the errors was correct. So I got to wondering if formating it in ext3 was the problem, but I was able to do it before. I decide to start from scratch, I reformated as ext2, reinstalled, and now everything seams to be fine.

Thanks for all the help.

Does installing KDE on the tablet's os take a lot of space?
Can someone post setp by setp directions for installing KDE?

I've used Linux for many years, mainly as a tinker rather than a true hacker.

Re: Running Debian in a chroot

Thanks, XL1200c, for figuring it out!

Of course, I'm an idiot. My script loads the kernel module for the ext2 file system (the second "insmod" line), but you had said in your post that you were using the ext3 file system. The answer was right in front of me. It probably would have worked if you had just changed the ext2.ko in that line to ext3.ko ... I'm sorry. Well, we'll know for next time... :o

As for getting KDE installed, there is really lots and lots of information on doing that. Many long, detailed help threads. In fact, there's a whole section of ITT devoted to KDE on the tablets.

Re: Running Debian in a chroot

I love this thread. It's really excitin, I'll join your guys fun in awhile.

....

1.35G per PB and the lowest I get was 1.42G Free space, installation still went thru.
I am not aware where can one find a setp by setp directions, I do have one step by step here, http://www.internettablettalk.com/fo...ad.php?t=20884
________________________________________
I repartiton my MMC boot to make 2.4 G partition on the rootfs. I then dl kde-installer-v3.deb from http://penguinbait.com/, the 5th one from top, kde-installer-v3 (boot from SD only), and click on the .deb file, it will automatically install under app manager. It took 40 min for my N810. Reboot, and KDE will be under Extra. Warning: do not turn off tablet while on KDE. Always log out KDE before turn off tablet.

Edit: need more FAT space, re-do another one, with rootfs 1.9 G and free space of 1.47 G, works, installation 45min

Hope this helps,
