Red Hat Bugzilla – Bug 185820
nv driver doesn't display mouse cursors
Last modified: 2008-05-06 20:27:15 EDT
Description of problem:
Mouse pointer is not visible when running x-windows. The mouse function works
(it tracks properly and the buttons can be pressed) but the pointer/arrow is not
This issue occurs when using the FC5 core nv driver on an Nvidia 6100 integrated
graphics motherboard (AsRock K8NF4G-SATA2).
(note: When using a standard PCI external graphics card (NV GeForce 5750 or NV
Geforce 6600GT, the cursor is visible)
Version-Release number of selected component (if applicable):
Fedora Core 5 test 3
AsRock K8NF4G-SATA2 - Motherboard w/Nvidia 6100 integrated graphics
AMD Sempron 64 3000+
Reproducible always using NV graphics driver (Autodetected in FC5t3) with a
motherboard using the Nvidia 6100 integrated graphics chip. Run X-Windows
(Gnome or KDE) and the mouse pointer will not be visible (the mouse will track
and buttons can be pressed however)
Steps to Reproduce:
1. Install FC5t3 on a Motherboard w/Nvidia 6100 integrated graphics (AsRock
K8NF4G-SATA2 for example). nv graphics driver will be autodetected
2. Run X-windows (GNOME or KDE)
3. Mouse cursor is not visible
Mouse cursor not visible
Mouse cursor visible
To confirm it was a graphics driver issue. I used the same motherboard with
an add-in PCI graphics card instead of the integrated 6100 graphics (I used both
a Geforce 5750 and Geforce 6600GT). The mouse cursor was visible with these

Xorg startup log
I'm seeing the exact same problem in FC5, except my motherboard is an Asus
A8N-VM which uses the same chipset and same integrated graphics chipset
described above. I've attached my X.org log in case this gives any clues. Also,
I don't know if it's related, but when I boot FC5 (x86_64) on this motherboard I
get a lot of ACPI related errors (I will file a kernel bug for this). I boot
with acpi=off to make things more stable, but even like this the mouse cursor
doesn't show when using the nv xorg driver. The mouse is operational, i.e. I can
see icons highlight etc. when I rollover them, I just can't see the pointer. I
have to use the vesa driver for now to get my mouse to show up properly.
I found a workaround to make the cursor/pointer work with the nv driver for the
time being... Add the following line to the "Device" section of /etc/X11/xorg.conf
Option "HWCursor" "off"
Turning HWCursor off at least made the mouse pointer display correctly again,
though the typing cursor/caret looks a little distored (i.e. there is weird gaps
in the vertical flashing bar). Definitely something buggy going on behind the
Here's a link to an article which talks about the ACPI issues with this board in
more detail and also talks about mouse and sound issues, it also links to a
patch for the ACPI issues:
As for the sound issues, it seems the Alsa project has created a fix in their
latest CVS code, probably will come out with the next release of their stable
tarballs. Hopefully we'll see that new alsa in FC5.
The article suggests turning off legacy USB support in the BIOS to get the mouse
working properly. I tried this and the mouse still doesn't work with HWCursor on
with the nv driver, even with legacy USB support disabled.

This is still unresloved (xorg-x11-drv-nv-2.1.3-1.fc8) on Fedora 8 Test 2 with
latest updates installed.
