This seems to be a common error particularly for nVidia users at 1440x900: bug 67826.
Try changing the resolution in usplash.conf (sudo nano /etc/usplash.conf
then sudo update-initramfs -u
) to something simpler, eg. 1024x768.
Or just apt-get remove usplash
completely; it's not exactly an essential part of Ubuntu. (The ubuntu-desktop
metapackage relies on it, but there's little harm in removing that.) Since xsplash comes up so quickly now for me in 9.10 I dropped usplash and don't really see any disadvantage. It'll probably be gone in 10.04 anyway.
Not really. There is a mechanism in apt for downgrading packages called 'pinning', which could theoretically be used, but downgrades in general aren't officially supported or particularly well-tested. So if you're worried about getting problems while upgrading, you should be even more concerned if you want to downgrade.
The best four ideas if you want to keep a stable system:
(1) wait. A fair number of upgrades come through the pike in the first few weeks after an Ubuntu release, since suddenly the number of installations and the variety of hardware and application use goes up radically. You'll have better odds of upgrading without trouble if you give it a month, even two. Also by then any problems that won't be fixed in this release cycle will be better documented and may have unofficial workarounds.
(2) Install a trial installation. Can you make room on your hard drive for a small fresh install? (Give it about 5GB, for the base and your most crucial apps). Play with it for a while and see how it goes. If it works, backup and upgrade your old system. Then you can see which one works better (upgraded or fresh). I always do this, since it lets me see how things work on my hardware without any disruption. It's pretty safe to resize partitions these days (but do backup, and if it's NTFS, defragment first).
(3) Try the live CD. It's not the real deal, but it may give you an idea of the things you won't have problems with.
(4) You can of course backup your whole partition with something like PartImage before you upgrade. This will also give you a path to replace your new install with your old one.
But really, just don't go for the bleeding edge. You value the stability of your system more than that.

Check this page on Ubuntu site. It talks specifically about upgrading 9.04 to 9.10. (Also make sure you do not install it in production. I think its in beta)
