this is my second version of Ubuntu, 11.04 worked really well for me, and I was really excited about 11.10... until I installed it.
I started by using the upgrade button in the upgrade app, but found that the new version was unstable - Firefox would crash every few minutes, I would be logged out very suddenly for no known reason, and so I decided to do a clean format and install, believing that this may fix the problem. Unfortunately, it seems that the problem is with 11.10 itself, as Firefox, Chromium, and various other programs crash for no reason, flash crashes and I still get chucked out of Ubuntu. Is there any way I can make this more stable, or should I just give in and go to 10.04?
In fact, Chromium just crashed while I was typing this up. What can I do?
UPDATE
Hardware: HP Pavilion with a Snapper MoBo, Running BIOS 3.08, with a 2.66GHz Celeron (32-bit), 2GB SDRAM with a GeForce 5200 GFX Card
GPU is running the latest driver, according to the additional drivers app.
UPDATE #2
Memtest returned a pass without errors, so it appears that the RAM is clean.
UPDATE #3
I thought I had it cracked - for a few days, everything worked fine, now just about every program is subject to random shut downs, the desktop vanishes a lot, the unity start menu thing disappears all the time when I'm using it and in Gnome, the desktop keeps crashing out - much as Windows explorer might do if it had some problems. I've decided to go back to 10.04 as there doesn't seem to be a way to get back to 11.04. Failing that, it's back to M$ - I don't like it, but at least it works.
