this discussion. I believe I answered some questions about how to fix it there...
First off you will have check what kernel version you have (this is done by doing "uname -r" in terminal). It is required that you have at least >=2.4.20. If you don't have a the latest kernel there are two options:
1. Either you download the latest kernel (actually 2.4.20 is a prerelease but I believe that there shouldn't be any problems with it).
2. Or you recompile your own kernel, doing the appropriate changes according to
this page (or you might aswell download 2.4.19 and compile).
If you
do have a good kernel you will have to load the "visor"-module in your kernel (this is done by su:ing and then using "insmod" to load the module). Probably you will also have to load some other module to get it working (me for instance had to load "usbserial" aswell).
Why upgrading your kernel when the visor module exists in them all? Well, the visor module, which is used to communicate with your Tungsten doesn't have the fingerprint of the Tungsten T (which makes it impossible for the module to recognize the Tungsten).
After loading that module (or after you've compiled it into your kernel, however I wouldn't suggest that) you will then need to download the
pilot-link package (either as RPM or you may also download, compile and install by yourself).
Then you'll have to choose a GUI and my suggestion is that you use "jpilot" (which you'll have to download separately) which I am using as it works perfectly although I have not got my mail going yet.
If you get mail running on your Tungsten I'd be happy if you tell me how to do it.
