PS2 mouse fails after upgrade when using 2.4 kernel
Last modified: 2007-11-30 17:10:46 EST
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
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
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
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.
I just saw in another bug that 2.4 support is going to be dropped
completly from FC3, so I'm closing this.
Created attachment 102118 [details]
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!
