Description Hans de Goede 2004-07-21 20:57:07 UTC 
When booting a 2.4 kernel after an upgrade to FC2 or FC3-test, the
mouse doesn't function, because of the usage of /dev/input/mice for
2.6 kernels instead of /dev/psaux and IMPS/2 instead of the real mouse
protocol.

X
=================================================================

For X this can be fixed by making /dev/input/mice, IMPS/2 the
CorePointer, and the original mouse config AlwaysCore

The current upgrade-path replaces the CorePointer config by
/dev/input/mice, IMPS/2. Resulting in a config with both the
COrePointer and the AlwaysCore extra mouse pointing to
/dev/input/mice, since /dev/input/mice as AlwaysCore already was
present for USB support.

If you change the original mouse to AlwaysCore and the AlwaysCore
config there for USB to CorePointer, then X works fine under both 2.4
and 2.6.

gpm
=====================================================================

GPM is rather harder to fix, this because the upgrade changes
/etc/sysconfig/mouse. My suggestion don't touch /etc/sysconfig/mouse,
this should contain info about the real mouse, not the way the kernel
reports it.

Next modifiy /etc/rc.d/init.d/gpm to check what kernel is running:
-2.4 just use the info in /etc/sysconfig/mouse
-2.6 if its a PS/2 mouse use /dev/input/mice, IMPS/2, other wise
continue as usual.
Comment 1 Hans de Goede 2004-07-21 21:10:05 UTC 
I just saw in another bug that 2.4 support is going to be dropped
completly from FC3, so I'm closing this.

modfied gpm start script to work with both 2.6 and 2.4

I'm attaching a modified gpm startscript for people still wanting to use 2.4
mixed wirh 2.6, note you should also manually downgrade to the FC2 modutils!
