FB stands for flashbang.. and THE LAST B IS A TYPO! HAHA!!
Ok, stop laughing. There currently is a bug in Linux servers that everything will appear dark.. a lot of people don't know this, but buy a Flashbang grenade, and throw it so it flashes you.. that will fix the darkness problem (yes it sounds fake, but.. yes). This bug should be fixed in B6.5C (which currently is only for Windows servers, but the Linux port should be out in a few days)..so hang tight.
