If it is more then one account logged in at a time, it is because of the way console.perms works. If it is the second case, then it is a bug in console.perms resetting the permissions. The workings of console.perms gets complicated, but a brief description is that it gives permission for the user logged in at the local console to use specific devices and/or resources. These are normally resources that are can not easily be shared. Things like sound, floppy drives, CD/DVD ROM drives, video hardware. It also limits access to resources that should not normally be accessed remotely. Where it gets complicated is where you have more then one user logged in locally. Who gets access? For the most part, it is the first user that logs in locally. But with fast user switching, and more then one X server running on the local machine, changes are necessary. From what I understand, this is a work in progress. Mikkel -- Do not meddle in the affairs of dragons, for thou art crunchy and taste good with Ketchup!
