Please note: I'm writing this on a J2ME SE Hazel, so I'll make this short, but the spelling nor the styling won't be great.
Ubuntu 12.04 LTS Wubi install on M$ Windows Vista (don't ask why).
2.2 GHz 1 core AMD CPU, approx. 744 MB RAM.
Unity was slow because of the ram, so I installed lubuntu-desktop, was happy with it for 2 months, until today.
To get the wifi working, I had to install some kind of additional driver (through the settings window).
LAN doesn't work, but that's a different topic.
I had a couple of programs running: pidgin, skype, keepassx (I think) and, most importantly, the settings manager.
In it I clicked "Language Manager" (or something like that). It said it needed to update some translations, so I clicked ok, and continued messing with the settings.
And then it happened. The screen turned to console.
It was full of text, and at the bottom there said something like kernel panic, going to text console. Alas, i haven't got a photo.
After finding out that the kernel panic is something like the win blue screen, I hard rebooted.
On booting the wifi didn't work. I triedthe troubleshoot guide in the ubuntu help, in vain.
I tried vista, doesn't work there neither. In the device manager it shows a warning icon on it, and simply says device unable to load (code 10).
Please don't say at this point that it's not an ubuntu problem, and that I should ask it somewhere else. Ubuntu created this problem, so I will at least try it here.
If you want more info, just ask.
