This sounds like a video driver issue on the client. It's probably using the default Vesa driver. Unfortunately, I've been away from ltsp too long to remember what you need to change it to, and how to change it. Jim McQuillan j...@ltsp.org Hi! If that is the problem, there is a guide here: https://help.ubuntu.com/community/UbuntuLTSP/AtomIon Pls report back and tell us how you're doing! I suppose you're using FAT Clients?
