I up-graded from 9.04 to 9.10. The result was devastating. Almost nothing worked well.

I am using a Sony VAIO, 2.0 MHz, 250 GB hard disk, 4 MB memory, etc.

Under Ubuntu 9.10, it runs like my old PB 450 of years ago. A bit of investigation shows the about half the people that upgraded have problems.

This brings back the old Windows days. I really don't want to be reminded of my Windows days.

I formatted the partition and installed 9.04 again.

That's my story...what's yours?

No visual difference, just use a Desktop
wallpaper / background by your choice,
to get what you like.

And copy the Ubuntu 9.04 /etc/X11/xorg.config,
..... which you of course keep as a backup .....
to Ubuntu 9.10 /etc/X11/ to get the resolution,
you are used to.

Then you shouldn't notice, that you are using
a different Ubuntu.
... Or was it another problem ? ?
.....

I repeat : Extremely slow, just horrible results across the board.
I have been using Ubuntu for a couple of years or more and this was the worst experience I have ever had.
I'll just stay with 9.04 until the experts fix it.

No, I don't see that.

Sound went completely and utterly awful. Not playing, loud noises, pops and crackles, utterly terrible. I admit I upgraded early, but the problems didn't go away when official release came. It didn't take me long to trace the problem to pulseaudio. It's a cool bit of software, but frankly it's gross over-engineering for the majority of users and should not be included by default. I removed it, but upgrades put it back again.

That's when I decided to jump ship. I had other minor niggles with Ubuntu too, and was losing confidence in it. I'm now using Arch Linux, and very happy indeed.

All right cantab, I am going to take a look at it. Thanks for the heads up.

I use fedora, so I have no problems at all
