for me could be a issue with the drivers or with shared memory allocation.
First test you can do is to do a spin with the intel driver present on
ppa:xorg-edgers. Here you can find the the newest opensurce intel
driver. The closed Intel Driver is not available at the moment for the
13.10 family. Lubuntu ship with 2:2.99.904-0ubuntu2, they have
sudo apt-add-repository ppa:xorg-edgers/ppa && sudo apt-get update &&
sudo apt-get dist-upgrade
Try with both SNA and UXA. You can revert to stock drivers using
ppa-purge (present on this ppa) if you like.
Second test you can do is try to add to your xorg.conf VideoRam to see
if the problem is the buffer size:
sudo lspci -vv | grep Region
and look for something like
Region 0: Memory at d8000000 (32-bit, prefetchable) [size=256M]
Region 1: Memory at e0380000 (32-bit, non-prefetchable) [size=512K]
Convert the first value in Kb (in this example 256*1024=262144) then
subtract the non-prefetchable value (use the largest you find if more
than one is present)
Then your new xorg.conf should be like this one:
Identifier "Intel Graphics"
Option "AccelMethod" "uxa"
If something goes wrong enter in recovery mode and delete the
xorg.conf. All should work to normal.
It's good have a look on Launchpad too to see if there are open bug
similar to what you exposed here.
Is up to you now. We'll wait some news.
