lightdm - Graphics problem on new lubuntu install

I've just install Lubuntu 13.04 32-bit on an old machine. When I boot, I essentially get no GUI. I have a cursor, and very poor 8-bit colour background, but no windows or buttons etc. I believe this is just a login screen, but I just can't tell.




Switching to tty1 (I think that's what it's called) via Ctrl + Alt + F1, I can login, and run programs as I would expect. Everything seems to be working except the GUI. It doesn't appear to be running lxde, only lightdm, but I think that's to be expected due to the fact I haven't logged in yet.



Unfortunately, I'm struggling get wifi to connect from the command line, so I can't run updates yet, although it was connected during install, so I think some were done then.



Any help in diagnosing and solving the problem would be appreciated. Which logs should I check? What other information would be useful?
