I've got a new system and am experiencing instability with it, so in need of narrowing down possible causes. After updating the bios, I still experience lockups. so I'm now running with just 1 harddrive installed and am wanting to see if that helps things or not.

Now my specific question today is an issue seen in powering up things this morning. I ran into this error msg popped up "Ubuntu 12.04 has experienced an internal error" and it was assocated with /usr/bin/Xorg.

Consulting older questions asked about this, I examined the /var/log/Xorg.0.log file but did not see any error lines (EE). Just wondering if people have suggestions on things to try, files to examine, or just what I might try to do to further debug this. I think my system is working fine now, even with this happening, but one never likes to see errors like this.

Have you considered the previous log file at /var/log/Xorg.0.log.old? – Lekensteyn Jun 4 '12 at 17:56

Sounds like it could be a graphics card driver issue. You could try using updated drivers by adding the xswat ppa:

sudo apt-add-repository ppa:ubuntu-x-swat/x-updates
sudo apt-get update
sudo apt-get dist-upgrade

If that fails to work, you may have to provide some more specific hardware information to help solve the problem - i.e. what graphics card you have, what other components such as wifi/networking cards (can sometimes cause problems) - if you are at all unsure about what hardware you have, you could use

sudo lspci


sudo lshw -html > hw.htm

(the last command writes hardware info to a html document).

Of course, don't forget to reboot after upgrading drivers. – Joshun Jun 9 '12 at 21:22
