Thank you for your replys . Sorry I wasn't more specific and clear. My bad.
I'm a terrible writer To begin with, I had 9 desktops after cssu upgrade.
I did not have modified hildon before upgrade.
Nothind didn't go south at the upgrade prosess either.
My problem is that (after upgrade) I can use only 4 of 9.
I cannot select more to be active. Which is wierd. I noticed this when I made a custom .desktop file:
nine background images, but only four came into view.
(when I had all 9 desktops active)
That desktop selection menu should slide in the lower part of screen but mine doesn't anymore.
Portait and landscape mode works fine.
So does hardware key switching work fine from desktop to another.
Take a fresh cssu testing/thumb flash and you certainly would have all 9 desktops to be used.
I currently have *maemo8.2 cssu thumb.
