12.04 really unstable for me

[type3]

Hi all, I upgraded to 12.04 and it's really unstable. The desktop freezes or crashes back to the login screen randomly. Happens after 5~10mins usage. Sometimes only running Chrome or Amarok.

Any ideas? Any logs I should look at? Or should I just upgrade to 12.10?


Thanks.

Post the content of /var/log/dmesg and your setup such as cpu, video card, memory, desktop or laptop. That would be a help. Did you upgrade via cd or usb and did the checksums of your download matches? Are you using proprietry video drivers. 12.04 has been a very stable release on a wide variety of machines so what you are experiencing is very unusual.

Also test a new user and see if they have the same problems

Occasionally, upgrades of a previous release to a new release don't go well.

I usually install a new release of Kubuntu when it is Alpha, and ride it through to release. I didn't do that for 12.04. I waited until it was released and installed then installed it because I am going to stay with it until it expires in about four years. By then this laptop may have expired, and so might I.

My experience with it on my previous Acer, which was purchased about the time 12.04 was released was that it was rock solid. When I purchased this Acer V3-771G in August I installed the latest upgrade of 12.04.1 on it and it has been rock solid as well. Perhaps doing a fresh install of the latest binary release will give you the stability you want?

I didn't know laptops expire!

I'll give that a go.

I'm in two minds whether to do that or the upgrade.

You didn't tell us what version you upgraded from. Also, do you have custom/third-party repositories and/or applications in use/installed?

I upgraded from 11.10. No custom repositories I don't think but I'll check.

Another clue: when the desktop freezes I can still move the mouse, but the gui is completely unresponsive.

did you try adding a new user like @james147 said ?

Not yet, but I will try it. I've also just uninstalled the graphics driver and installed another one ('version current' -> 'post-release updates'). Will see how that goes.

Just out of curosity, is the keyboard still working? Can you CTL-ALT-Fkey (i.e.: CTL-ALT-F1) to another command line session and login? If so, this will tell you that the underlying system is still running and just X has hosed itself up.

Cheers,

Uninstalling and reinstalling the nVidia driver seems to have done the trick! Thanks for all the good suggestions.
