The installer correctly found my PS/2 mouse on my sparc64/PCI system, and configured XF86Config appropriately. Yet it did not detect that I also had a PC Keyboard, thus XF86Config was left with "sun" as the keyboard type which obviously didn't work. A quick hack solution (which would work fully) would be to put: XkbRules "xfree86" XkbModel "pc101" XkbLayout "us" Into XF86Config's keyboard section if a PS/2 mouse is found, because to my knowledge there is no way to have a PS/2 mouse in an Ultra/PCI system and not have a PC Keyboard attached as well.
I believe Matt has fixed this. Matt if not, please reopen.
The problem is still there in the current build.
Dave: I think I have fixed this, it is hard to test because we don't have a box locally. I switched the test from strcasecmp to strcasestr looking for "ps/2" as the mouse type, as I am assuming that it may be getting set to something like "generic3ps/2" or something similar in mouseconfig -- if we could see /etc/sysconfig/mouse it would be nice. In any case, please give Xconfigurator 4.1.6 a whirl, and report back.
