Hi Nico, we have buyed a bunch of IMPS/2 mice from Fujitsu Siemens Computer. When I start gpm version 1.20.0 or 1.20.1 on them I get in 4 of 5 cases the following error and of course the mouse is not working after that. faui02e:~# /usr/local/bin/gpm -Rimps2 -m /dev/psaux -t imps2 === ERROR ===: [/tmp/gpm-1.20.0/src/mice.c(1755)]: imps2: Auto-detected unknown mouse type 250, assuming standard PS/2 It is a IMPS/2 mice with 5 buttons (or 3 buttons and a wheel). If you insist I can send you one via snail mail. The following patch solved the problem for me: diff -ruN gpm-1.20.1.orig/src/mice.c gpm-1.20.1/src/mice.c --- gpm-1.20.1.orig/src/mice.c Tue Dec 24 23:57:16 2002 +++ gpm-1.20.1/src/mice.c Mon Nov 10 12:52:20 2003 @@ -1888,7 +1888,7 @@ gpm_report(GPM_PR_INFO,GPM_MESS_IMPS2_AUTO); return type; } - if (id != GPM_AUX_ID_PS2) { + if (id != GPM_AUX_ID_PS2 && id != 250) { gpm_report(GPM_PR_ERR,GPM_MESS_IMPS2_BAD_ID, id); } else gpm_report(GPM_PR_INFO,GPM_MESS_IMPS2_PS2); Greetings, Thomas -- Thomas Glanzmann ++49 (0) 9131 85-28725 Department of Computer Science IV Martensstrasse 1 D-91058 Erlangen Germany University of Erlangen-Nuremberg http://wwwcip.informatik.uni-erlangen.de/
