Description Vivek Dasmohapatra 2015-02-17 17:57:34 UTC 
Some users are reporting that when using the 01.org backports on Ubuntu 14.04 and Fedora 20:

  https://01.org/linuxgraphics/node/442

We didn't see this behaviour in our testing, and apparently only some
users are seeing it.

The list of packages which u14.04 upgrade list is:

i965-va-driver
intel-gpu-tools
libdrm-intel1
libdrm-nouveau2
libdrm-radeon1
libdrm2
libegl1-mesa
libegl1-mesa-drivers
libgbm1
libgl1-mesa-dri
libgl1-mesa-glx
libglapi-mesa
libgles1-mesa
libgles2-mesa
libopenvg1-mesa
libosmesa6
libva-drm1
libva-egl1
libva-glx1
libva-tpi1
libva-wayland1
libva-x11-1
libva1
libwayland-egl1-mesa
libxatracker2
va-driver-all
vainfo
xserver-xorg-video-intel

And the f20 upgrade list is:

drm-utils
intel-gpu-tools
libdrm
libva
libva-intel-driver
libva-utils
mesa-dri-drivers
mesa-filesystem
mesa-libEGL
mesa-libGL
mesa-libGLES
mesa-libOSMesa
mesa-libgbm
mesa-libglapi
mesa-libwayland-egl
mesa-libxatracker
xorg-x11-drv-intel
xorg-x11-drv-vmware
xorg-x11-server-Xorg
xorg-x11-server-common

Which leads me to believe there's a problem in xserver-xorg-video-intel/xorg-x11-drv-intel as that looks like the likely common component in both.

You need upstream kernel and ddx as both contain fixes for the issue.

(In reply to Chris Wilson from comment #1)

Do you happen to know when the fixes went in, roughly?
Comment 3 Chris Wilson 2015-02-18 09:53:20 UTC 
3.15-3.16 had some bugs with not updating the cursor size correctly, iirc. And in the ddx, the last arbitrary cursor size bug was fixed in 2.99.915.
