Since Ubuntu 12.04, I've tried every version available on my work desktop and they've all had the same bug/problem: My system freezes at seemingly random times and it is completely unresponsive (can't even ssh into it from another computer). I really enjoy the Ubuntu experience except for this bug, but it is happening as much as 3 times per day. I do not believe it's a hardware problem because arch linux runs smoothly as does windows 7.
On irc, someone told me that most hard freezes like this are because of the graphics drivers. So I switched from nvidia-current back to the default driver and I still see the problem (but possibly less frequently).
My question is, where can I find more information about this freeze? What log files should I be looking at? I can't seem to find anything obviously wrong in my syslog, dmesg or x11 logs. Is there a way to turn the log level up? Would there even be anything to log if it's a hard freeze?
Essentially, I'm just asking for information on how to better troubleshoot my issue so I can search for similar questions / bug reports and to actually understand whats going on. I know it's completely irresponsible for me to expect you guys to magically fix this, but I am kind of hoping its a configuration problem and the simple answer is to turn of feature xyz.
Thank you in advance, jflowers
