Just upgraded from Maverick 10.10 to Natty 11.04 and went smoothly even with the new Unity desktop.

But when restarted from shutdown, the screen was jumbled and was only just able to restart (the screen jumbled but could just make out the dialog boxes. Then logged in in safe mode. Ever since, have only been able to run in the 'old' Ubuntu without features mode. I have an oldish HP/Compaq nc6000 with 20Gig disk and 675Meg memory.

I guess it's a bug, but wondering how or what went wrong since it seemed to run fine just after the install.

I'd suggest the machine isn't powerful enough to run Unity properly. Ubuntu as Canonical's flagship, is really aiming for the higher end market and leaving owners of low powered machines to try to figure out things for themselves.

If you want to stick with Ubuntu, or its variants, my recommendation would be to run Ubuntu Classic which is the old Gnome 2.32 or try a lighter flavour like Lubuntu which by all accounts is not a bad OS.

Personally I'd ditch Ubuntu, and the reason is it wont work on my laptop anymore without major fiddling, and put Debian on it.

EDIT: did you install Unity or Unity2D? Unity2 is for lower spec machines and it might be a better option if you are set on Ubuntu.

Appreciate the prompt reply. Yes, newbie to technical stuff but strong advocate of Ubuntu. Yes, currently running Gnome 2.32 as you suggested. Unity - not sure of the version, but much prefer the 'old' Ubuntu Classic environment anyway, even though we have iMac back home. Ubuntu has been fantastic for me for over 3 years. I'll take a look at Debian as you suggested. Also Lubuntu.
Thanks again for the tips.
