Nouveau - Mar 2015 - [Bug 89620] New: Nouveau driver for Nvidia card GeForce GT 550M]

https://bugs.freedesktop.org/show_bug.cgi?id=89620

            Bug ID: 89620
           Summary: Nouveau driver for Nvidia card GeForce GT 550M]
           Product: xorg
           Version: unspecified
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: high
         Component: Driver/nouveau
          Assignee: nouveau at lists.freedesktop.org
          Reporter: grgoffe at yahoo.com
        QA Contact: xorg-team at lists.x.org

I presume that the nouveau driver is responsible for drawing the mouse pointer.
My pointer seems to be redrawn constantly producing what Windows used to call
"Tails". Multiple images of the mouse pointer. Additionally, there
seems to be
some wild pointer because data from somewhere else in memory sometimes appears
with the mouse pointer.

There appears to be no messages related to this behavior in the dmesg buffer.

Occasionally I get a segfault. I have Xorg.0.log files and their corresponding
dmesg buffer files available if needed.

This is a Fedora 21 x86_64 system with a kernel at 3.18.8-201.fc21.x86_64

Sounds like you are seeing a software cursor. Can you include dmesg for your
system as well as your Xorg.0.log?

Hi,

This problem appears to have been resolved. Here are the kernels on my system:

/vmlinuz-3.19.3-200.fc21.x86_64
/vmlinuz-3.19.2-201.fc21.x86_64
/vmlinuz-3.19.1-201.fc21.x86_64

The last one causes the problem but the "-2" and "-3"
kernels it's gone.

The kernel MIGHT not be the solution though because I tried and failed to
install the latest NVIDIA driver. The installation fails due to missing fields
in some Kernel structures. NVIDIA-Linux-x86_64-346.47.run is the filename. I
can't figure out what they may have modified to effect this problem. They
did
put "nouveau" in a file in /etc/modprobe.d. The filename and it's
contents are:

 nvidia-installer-disable-nouveau.conf
# generated by nvidia-installer
blacklist nouveau
options nouveau modeset=0

Do you see anything here of interest? Do you need more info? Let me know.

Thanks for your help with this.

There a several things of interest especially to you:

1) this is a optimus notebook with a software mux -> the iGPU draws the
cursor
2) you are missing the nouveau driver for X

i tend to close this as invalid...

As far as I know the driver IS present. This problem seems to have gone away
with a newer kernel.

Which laptop are you talking about? Mine is an Asus n53sn.

OP says that the problem went away with a fresh kernel.
