I've just installed Ubuntu on my PC as a dual-boot OS with Win 7. It works fine, except when I boot it hangs for about 20 seconds on the login screen before letting me type in my password.
System specs: Ubuntu 12.04.1 AMD 4170 quad-core CPU 16 Gb Corsair RAM Radeon 7850 graphics card
Not sure what logs to check to try and find the problem. All suggestions welcome.
