I've bent my system bad. When I boot, it comes up in the CLI -- not in slim, to XFCE. It does the regular login and the .bashrc tricks, and startx starts XFCE just fine.
I was trying to get my router to copy its config to the TFTP dir, and I did something from how-tos on the 'Net (all kinds of different suggestions) that told something not to start the GUI. I'm sorry, but I don't know enough to say about what I did or what's broken. Anybody have any ideas better than a reinstall? Or questions to ask? Knowing what to do to get TFTP going would be nice too. It used to work flawlessly, but now the dir on my disk and all my backups show /tftpboot empty. And the router docs (a Cisco) don't have much to say about it. It looks like I have the TFTP dir misconfigured on my disc, and it's been years since I got things working. -- Glenn English
