Re: Mouse Support in Kernel 2.6.8

[Dinesh Ahuja]

I have observed something which I would like to share
with you. Do we need to change XF86Config file when we
are migrating from Kernel 2.4 to 2.6.8 ?

Whenever I boot my system [ either in Kernel 2.4 or
2.6.8], I am prompt by kudzu to configure/
unconfigure the following hardware devices:

1. LGI|8051
2. Generic PS/2 Wheel Mouse

If I configure LGI|8051 only [not Generic Mouse
because If I configure Generic Mouse, then I donot get
Mouse Support in Kernel 2.4] in my Kernel 2.4, then
everything works fine and I get mouse support. But If
try to do the same thing in Kernel 2.6.8 [ i.e
configure LGI|8051 and don't configure Generic PS/2],
then my Kernel gives error in launching X Server and
error is as follows:
xf86OpenSerial can't open device /dev/ttyS1

My XF86Config contents are as follows:
# XFree86 4 configuration created by
redhat-config-xfree86
