Description of problem:
I have a Toshiba Portege laptop. All ACPI stuff works fine in kernel 2.6.12-1.1398_FC4. I used the fnfx ( http://fnfx.sf.net ) daemon that came with FC4 for Fn keys.
Recently, I upgraded to kernel 2.6.13-1.1526_FC4. Now, when I switch the display to an external monitor or LCD projector and switch back, the cursor disappears.
I have a simple USB optical mouse and a Synaptics Touchpad,
usb 2-1: new low speed USB device using uhci_hcd and address 2
input: USB HID v1.10 Mouse [USB_PS2 Optical Mouse] on usb-0000:00:1d.0-1
model: 1, fw: 6.2, id: 0x88a0b1, caps: 0xa04713/0x0
The cursor disappears completely. However, when I move my mouse, icons get highlighted ( as if the cursor is over them ). On double clicking, the icons work. This means that the driver and device is working fine. Only the cursor is missing.
I am also running xorg-x11 version 6.8.2, release 37.FC4.49.2
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.Switch the display to an external monitor or LCD projector
2.Move the mouse
3.The cursor would have disappeared.
Actual Results: The mouse cursor disappears.
Expected Results: The mouse cursor should have been on screen.

2.6.14-1.1637_FC4 has been released as an update for FC4.
Please retest with this update, as a large amount of code has been changed in
this release, which may have fixed your problem.
The problem seems to have been fixed in 2.6.14-1.1637_FC4
A lot of other issues with ACPI also seem to have been fixed. The stuff is
working really well.
Thanks a lot.
