I couldn't find a Cotton Candy-specific forum. Perhaps someone here will have advice. My apologies if I'm off-topic.

I'm using Linaro on the FXI Cotton Candy. At least every few hours, it experiences an X server crash, which logs me out.

Here is an example syslog message from the time of the crash:

Nov 20 08:27:46 linaro-ubuntu-desktop gnome-session[3350]: Gdk-WARNING: gnome-session: Fatal IO error 11 (Resource temporarily unavailable) on X server :0.#012

A brief search online suggests this may be a problem with the video driver. But I'm not sure. I will be very glad of any assistance.

The crash is intermittent and difficult to reproduce. It seems to happen when I'm 'doing something', e.g. opening a new window, clicking a link or scrolling in Firefox, resizing a window, or viewing a photo attached to email. It does not seem to crash when the machine is idle.

I'm running Linaro (Ubuntu-beta-20130309.zip from FXI's Web site), which I reinstalled earlier this week then did 'apt-get update' and 'apt-get upgrade', and configured in various simple ways (e.g. software firewall, wireless networks, software installations using apt). The X server crash has happened before and after the reinstallation.

Without a swap file, there were some out of memory problems. I added a swapfile, which removed the out of memory problems. The X server still crashes.

I've also emailed FXI support but have not yet heard.

Thank you very much, in advance,

Daniel
