Step by step Guide: Screen rotation after Diablo upgrade
 

Pros: It works
Cons: You will NOT be able to uninstall the 5.2008.43-7 upgrade on the modified booting OS. I have no idea what does that mean to the tablet, now or future. I did mine on a MMC boot, and the internal flash 5.2008.43-7 upgrade is NOT affected,i.e., what you did to OS on MMC boot, in general does not translate to the OS in flash system. In general...

Prequalification:
- 5.2008.43-7 upgraded
- advanced-backlight installed

Enable Extras-devel
- AppManager>Menu>Tools>Application catalogue...
- New
- Cat name: maemo Extras-devel
- Web address: http://repository.maemo.org/extras-devel/
- Distribution:
- Components: free non-free
- Disabled:
close AppManager.

X Terminal
~ $ gainroot
( substitute cmd1-3 with cut and past from below)

/home/user/ # cmd1)
size 1529986
/home/user/ # cmd2)
size 694854
/home/user/ # cmd3)

unpacking....

/home/user/ # reboot
Disable extras-devel
AppManager>Menu>Tools>Application catalogue..>Edit extras-devel and checked the Disabled square.

done

cmd1) = cmd2) = cmd3) = Credits: The above are all copied from wiki (http://wiki.maemo.org/Rotation)

My N810/N800 are both booting from /MMC1.

The 770 setup is MMC boot with 48 MHz clone, http://www.internettablettalk.com/fo...mmc+boot+speed.
The 770 does NOT work, it does flip, but it also messed up the touchscreen, the hardware button works though.....anyhow, I cannot make it work. It is still fun to see it flips.

:D Great job!

You beat me to it :p

I had the thought this past weekend that I should post a quick rotation guide... I'll have to give this a try when I get home...


Silly question: What does the "size" command do? I don't remember having to use it before....

Thanks
Snoshrk

Re: Step by step Guide: Screen rotation after Diablo upgrade
 

The size is the output from the xterm when the commands are issued. It is for cross-checking to make sure things are going allright. I am pretty impress with the rotation, even video rotates!

Hey Bun...

Tried this last night.... can you edit cmd1 & cmd2 so that they do not have the "..." in them? A straight cut&paste on the tablet choked on the hidden bits.

:)

Re: Step by step Guide: Screen rotation after Diablo upgrade
 

I have an upgraded N800, and I remember that installing screen rotation took me only 1 click ....

I dont remember the exact thread, but I'm sure it's very easy

Re: Step by step Guide: Screen rotation after Diablo upgrade
 

This is what i use
root then

paste into xterm step;1
apt-get install advanced-backlight osso-software-version-rx44-unlocked

paste into xtermstep2
maemo-mini-curl -o kernel-diablo-flasher_2.6.21-200842maemo1rotationfast_all.deb http://outpo.st/rotate/kernel-diablo...onfast_all.deb
maemo-mini-curl -o xserver-xomap_1.3.99.0~git20070321-0osso20083801rotation_armel.deb http://outpo.st/rotate/xserver-xomap...tion_armel.deb

reboot ok

Re: Step by step Guide: Screen rotation after Diablo upgrade
 

Does the 5.2008.43-7, Feature upgrade (unlocked) still show up as an available update in Application Manger?

Re: Step by step Guide: Screen rotation after Diablo upgrade
 

***** Very Important: ******

Install the correct version for your device:

N800 rx34

N810 rx44

N810W rx48

Code snippets from the wiki, might be a little easier to cut & paste on the tablet...:D

Re: Step by step Guide: Screen rotation after Diablo upgrade
 

@Snoshrk: Thanks for pointing out the obvious, the original post has its URL html format shortened into "..." and causing the trouble as you have kindly pointed out in above post. It is now working, one can point, cut and paste. Thanks,

bun

Re: Step by step Guide: Screen rotation after Diablo upgrade
 

Yes somewhat, if running OS 30-2, 4.2008.36-5 feature upgrade is still showing as an available update in AppManager under Check for updates.

No. After one installed the rotation modification, 5.2008.43-7 feature upgrade under Show installed app, it now show an icon like a broken installed app, a red with 3 black squares. If click, it said "Unable to uninstall..." I guess its from using a hacked version ("unlocked"). Please some guru elaborate here... Thanks

Re: Step by step Guide: Screen rotation after Diablo upgrade
 

How do you navigate when rotates sideway? Say, you are now rotated sideway, and your app selection is outside the screen, how do you choose your app? It is NOT a problem if rotates upside down. Overall, the rotation apps run very smooth, has not seem any hichup so far and the rotation is eye blinking, thanks for everybody works on this rotation app.

TIA,

bun

Re: Step by step Guide: Screen rotation after Diablo upgrade
 

:confused:

I use portrait rotation with several websites like gmail, greader etc. (hard buttons to the top N800) and the Minimalist theme of TMO (wow that just doesn't flow like itT)

When you say app selection...what do you mean? The left hand side of my screen stays on the left and the right side spills off the screen when rotated to portrait.

Re: Step by step Guide: Screen rotation after Diablo upgrade
 

Thanks Bun. First, I have not seen you around here in a while and had hoped you had not abandoned us! Second, rotation is a wonderful thing to have, so the more advertisement the better!

I tried to do my part a while back, and even uploaded necessary debs when they had been pulled from the ssse2.net/rotate site (they might be back now).

Re: Step by step Guide: Screen rotation after Diablo upgrade
 

Thanks for the kind words. Just getting a little bit busy on my day work.

I just installed digia @web. They have an onscreen button to rotate the screen, one does not have to get off full screen to get to the task bar to rotate screen, it is very cool. To install digia @web, enable extras-devel and install via appManager.

bun

Re: Step by step Guide: Screen rotation after Diablo upgrade
 

So, how do I select the Extras? In this case, I know i can use the Dpad, but not always possible, is there any function to move the screen, so one can get to the selection button?

TIA,

bun

Re: Step by step Guide: Screen rotation after Diablo upgrade
 

please someone wit the knowledge elaborate on that becase I was thinking the same exact thing. Another thing is how do I uninstall if I wanted to because i need to know how to undo all the crazness that I do to my tablet. thanks

Re: Step by step Guide: Screen rotation after Diablo upgrade
 

Uninstall.........umm :confused:

How about a COMPLETE backup, and just slap it back on when attempting "uninstall"?
It works for me.

Re: Step by step Guide: Screen rotation after Diablo upgrade
 

As I understand it, your cmd3 modifies the kernel, and the reverse cloning procedure will only restore the rootfs. If you really want to get back to the place where you started, you will have to reflash the kernel as well. See http://wiki.maemo.org/Updating_the_t....2FN800.2FN810 .

It used to be the case that you could not reflash just the kernel if your PC runs Windows - you had to reflash all the firmware at once. This might have changed with the new Linux/Mac/Windows flasher-3.5 . The wiki unfortunately does not clarify this point.

Re: Step by step Guide: Screen rotation after Diablo upgrade
 

Thanks for the new info on the flasher-3.5. Will try some time.

The backup mentioned above is a link to here, is a different beast, it is a complete retore of everything back to the place where you started. It saved my butt more than many many times :)

Re: Step by step Guide: Screen rotation after Diablo upgrade
 

Thank you, bun. I have edited my post to read "reverse cloning" instead of "backup". I wrote "backup" originally because that was the term you had used in the post that I was quoting. I realise that the procedure is different from the GUI Backup application, and that readers might be confused by a different use for the same word.

The fact remains that the cloning (or reverse cloning) copies the rootfs only. It does not restore the kernel to the state it was in before execution of the dpkg command in your OP. The only way to restore the kernel is by reflashing it.

Regarding a restoration of the rootfs to the internal flash, Fanoush suggested a procedure for backing up a clean, unused copy of the rootfs on /media/mmc1, using mkfs.jffs2. (This is different from the cloning procedure, in that it does not create a bootable partition.) The backup can be restored to the internal flash by using flash_eraseall and nandwrite commands. See Fanoush's post
http://talk.maemo.org/showthread.php?p=33348#post33348 .

Fanoush also bundled the relevant utilities in his initfs_flasher. You will find mkfs.jffs2, flash_eraseall and nandwrite in there, and also sumtool. There are posts by Fanoush and nhanquay in the forum, explaining how to use sumtool to create a faster-booting rootfs from the backed-up file.

The relevant commands for restoring the internal flash can be run from a bootable partition on either SD/MMC card.

The advantage of this procedure over the "reverse clone" is that the resulting rootfs on internal flash is completely unchanged since the backup was created. The disadvantage is that it takes up a lot of space on your media card.

BTW, I came to the present thread after following the wiki to enable rotation. I had just written a post suggesting that someone should rewrite the wiki to make the process more accessible to users, and then I discovered that you had in effect already done it. Congratulations to you as usual for your valuable work.
