Aloha list, I have installed Fedora Core 4 Test 2 on a spare box that I will eventually be using for a firewall+router. Right now it is a test box for the new FC4 release. This box has had RH7.2 and RH 9 on it in the past and the mouse worked fine with those installs. I am having trouble getting FC4 to recognize and use the mouse, and this is a new problem. I have tried just about every combination available in system-config-mouse to no avail. Many combinations error out with an error something like 'inputattach: cannot set line discipline'. Other combos do not error out and mouse services appear to start OK, but the cursor on the screen (text screens and X) does not respond to the mouse. The mouse is a two button Logitech First Mouse P/N 811327-00. I have also tried a Logitech MX 310 USB/PS2 mouse and that one doesn't work here either although the MX 310 mouse is working quite well on my FC2 system that I am writing this note from. Any ideas would be greatly appreciated. Mahalos in advance, Ben
