I tried system-config-mouse on a couple of computers, but it didn't appear to change xorg.conf , even though I changed my choice of mouse. The change worked during the current session, but had disappeared when I logged in again. Have I misunderstood the purpose of this command? -- Timothy Murphy e-mail (<80k only): tim /at/ birdsnest.maths.tcd.ie tel: +353-86-2336090, +353-1-2842366 s-mail: School of Mathematics, Trinity College, Dublin 2, Ireland
