I was having trouble printing from KDE apps, so I fired up the control center, which gave me the choice of 'generic UNIX LPD system', CUPS, and a few others. Since there's a CUPS server on my network that all non-KDE apps on the same computer are happily printing to, I selected CUPS. The control center showed 'initialising manager' or some such phrase, and then became non-responsive, so I had to resort to kill -9 tactics. I then tried again, but this time the printer configuration immeditely went to 'initialising manager' - non responsive. Fine, killed it again, deleted the corresponding config file in ~/.kde, tried again, and everything was back to square one.
I then made a catastophic mistake: I went into administrator mode, and there tried to select CUPS, thinking there was perhaps a privilege problem somewhere. This led to the same non responsive configuration screen. I thought I could fix this the same way as before, but no such luck. I can't find the blasted configuration file that I need to delete for a renewed attempt at configuring a printer. I'm now completely stuck. I can't fix or remove the configuration file manually, and the configuration tool hangs, at least in administrator mode.
Given that this is a Redmont style problem, I could try the classical Redmont fix, and delete everything that so much as smells of KDE and re-install, but that really goes against the grain, not to mention that it will take a day of compiling.
Does anyone out here know which file I should vent my by now considerable anger on, to at least get back where I started? Or even what the name of the offending file is, so that I can have 'find' hunt it down for me?
