Hello once more,
I have been using Ubuntu 12.04 LTS as my only operating system on a nice two year-old computer for about 2 months now. I've seen while certainly Linux is better than Windows in lots of aspects, Unity causes some problems. But that's OK, the Ctrl+Alt commands deal with that fine.
Suddenly, on this normal day, I get a black screen with the cursor on the center and the words (approximately):
: unable to handle kernel on the bottomeleft corner of the screen. I had to pull the plug, nothing else worked.
So here's what I was doing: about five minutes ago (at the time of this writing), I was running Chrome with lots of tabs open, one terminal window with VIM, Google Earth (which BTW is better on Windows, plus there's confusion when you try to close it, it doesn't seem to maximize all the way) and Virtual Box. I tried to start my WinXP VM and a small message box appears, saying "trying to create process". Then I go to Switzerland in Google Earth, see a couple of things, and close it.
I go back to the VM creation of process dialog: It never goes beyond 0% though, so I close it; bjut it still tries, so I go to the terminal and kill the Windows XP window and with it the dialog box. Then I see "aborted" below the virtual machine's name, which is logical. I click to start, and it does so immediatly and normally. A little after I go back to Chrome (XP takes a while to start), I see the error.
Is this reported? Is it an Ubuntu, Linux, Google Earth, Virtual Box problem? How? How can I fix it? Also, this may be relevant: a few days ago, I followed various instructions to stop the cryptswap mounting problem on boot (I encrypted my home folder on installation). Why did this happen? Is it related to any of the stuff I mentioned? Or is it some other problem?
