I recently got a new laptop and installed 12.04.1 on it. I am have some annoyances and issues and I want to see if I can find the root cause (and maybe submit bug report/patches). Where would I begin to debug a problem? I am sure it depends heavily on what type of problem I have but are there any general places to look?

My first issue is when the screen turns off for power-save, it does not come back on. My workaround is to suspend and then wake it up. When I unlock it after it wakes up, I can see that the keys I pressed to wake it up were registered by the active application. So the computer is alive, just the screen is not on.

My second issue is the USB-to-Ethernet adapter turns off after a while. The connection drops and the light turns off. If I unplug it and plug it back in, Ubuntu recognizes it and enables the wired connection.

The third problem is the WiFi is disabled after a suspend. I have to click on the network manager and enable wireless before it will pickup the wireless networks. The last couple days this one hasn't happened, so something could have fixed it.

Any pointers for debugging theses issues? I am a computer engineering student and I know programming and have some knowledge of Linux but not too much.

Welcome to Ask Ubuntu! Our site works best in a Q&A format. As such, we try to limit one question per post. Could you please split this post into multiple questions? Thanks! – WarriorIng64 Sep 17 '12 at 12:02
@WarriorIng64 I feel this is one question. I am asking how to debug theses, I am not asking them to be debugged for me. If I cannot figure it out myself, I will then ask specific questions. I was hoping for locations of log files, things to look for in said log files, tools to use, etc. – TwistedTech Sep 17 '12 at 21:16

You specifically mentioned three separate issues you would like to try to debug. It is easier for us to help you with these if they are each posted as a separate question, since then a person who might be knowledgeable about one or two of them would not feel compelled to know how to address all three before they can post an answer. It also helps other visitors with similar issues find relevant information quicker without also having to wade through other things they don't need to. – WarriorIng64 Sep 18 '12 at 4:13
