Q. I’m using Gnome under Ubuntu Linux and my numeric keypad is disabled. Pressing numlock key does not work any more. I’m not able to use numbers or special symbols from numeric keypad. Reboot does not help or using different keyboard does not help. However, numlock only works if I switch to text console by pressing CTRL+ALT+F1. Now, I’m dam sure this is related to X.org or Gnome. How do I fix this problem?

Q. Physical Address Extension (PAE) refers to a feature of x86 and x86-64 processors that allows more than 4G bytes of physical memory to be used in 32-bit systems. The x86 architecture presently uses only 36 bits out of 52 bits possible. On x86-64 processors, PAE is obligatory in native long mode; currently 40 bits are used out of 52 bits possible. How do I find out if my Linux kernel supports 36-bit or more physical addressing?
