Hello, I have an USB mouse which works fine under X and GPM. Sometimes I need to plug my mouse into the PS/2 conector, so I use an original adaptor USB->PS/2. Under X I only set /dev/psaux protocol IMPS2 and my mouse works perfectly. Under GPM my gpm server oops saying: Jul 25 23:11:08 notas gpm[827]: write_ps2: 1 0, 8 Jul 25 23:11:08 notas gpm[827]: PS/2 mouse failed init Jul 25 23:11:08 notas gpm[827]: oops() invoked from gpm.c(1019) Jul 25 23:11:08 notas gpm[827]: mouse initialization failed: Inappropriate ioctl for device I run it as gpm -m /dev/psaux -t exps2 originally I run it as gpm -m /dev/input/mice -t exps2 I use gpm version gpm 1.19.6 included in debian woody distribution kernel 2.4.19-rc3 from ftp.kernel.org libc6 2.2.5-10 included in debian woody distribution Thanks for your help Michal
