     there's a regression in the xf86-video-nouveau driver that came up
     in
     1.0.3 that causes the desktop to bounce around in virtualbox
     whenever
     using HW acceleration in cinnamon and gnome 3, but not in fallback
     or
     cinnamon 2d, only happens in virtualbox and not the host, I've
     confirmed
     it was the graphics driver on the host because it happened with the
     1.0.3 driver but not the 1.0.2.
     anyone else having this problem? I'm using GeForce GTX 560 Ti

     Hi Pouar
     Can you open a bug, following these instructions [1]
     Ideally you can try bisecting the issue - there are only 10 changes
     that may have caused the issue
     Cheers

     I just did

     by I just did I meant the bug report, not the bisecting, I have zero
     experience with driver programming, much less graphics driver
     programming, so I wouldn't know what to look for, I signed up for
     this mailing list to keep track of the different driver issues and
     bugs and their progress

You don't need to have any experience in driver programming to bisect this bug.

git clone git://anongit.freedesktop.org/git/nouveau/xf86-video-nouveau/
cd xf86-video-nouveau/
./autogen.sh
make

If you can compile successfully, do:

1) git bisect start xf86-video-nouveau-1.0.3 xf86-video-nouveau-1.0.2
2) make && sudo rm /usr/lib/xorg/modules/drivers/nouveau_drv.so && sudo cp src/.libs/nouveau_drv.so /usr/lib/xorg/modules/drivers
3) Restart X. Try to reproduce the bug.
4) If you can't reproduce it - do "git bisect good", if you can - do "git bisect bad".
5) Go to 2). After ~4 compiles it will tell you about first bad commit - this
is what we want to see.
