Red Hat Bugzilla – Bug 143893
with ACPI=OFF synaptic touchpad not detected/useable
Last modified: 2015-01-04 17:14:32 EST
Description of problem:
The system is a Compaq R3000z (Athlon64) with multi-boot systems
installed. WinXP is installed in hda1 (squoze down), a minimal FC3
i386 in hda3, swap as hda2, FC3 i386 everything install in hda5 and
FC3 x86_64 everything install in hda6. The problem occurs with both
i386 and x86_64 systems.
The synaptics touchpad works fine with WinXP. It also works fine with
ACPI=ON for both i386 and x86_64 (comes up as a "generic" PS2
two-button input device).
However, booting with ACPI=OFF, the synaptic touchpad is not detected.
Version-Release number of selected component (if applicable):
FC3 with all "current" updates applied including kernel 2.6.9-1.698_FC3
I am closing this NOTABUG. With the latest BIOS upgrade from HP (F33
or SP29481.EXE) I am able to have both the snaptic touchpad and USB
mouse work with acpi=on which is a better solution.
