Just been tinkering with my fluxbox window manager and been reading the FAQ.
According to the FAQ you need to edit the .xinitrc/.xsession script (depending upon your distro I guess) to get thinks like xclock to startup automatically.
Well I can't find either of these files anywhere on my computer.
I also did:
Failed to load groupfile:
BScreen::BScreen: an error occured while querying the X server.
another window manager is already running on display :0.0.
Blackbox::Blackbox: no managable screens found, aborting
Fluxbox: Unknown error.
I did this because I was interested in the fancy transparent menus but could not find the option in the fluxbox-menu. fluxbox -i should say RENDER if the option is available. Not sure why it tells me that blackbox is running.
