commit 97cf53cc2ad7ecfdd495133bad31d0ec7d939326 Author: Søren Sandmann Pedersen Date: Mon Oct 21 16:58:54 2013 -0400 ephyr: hostx_screen_init(): Fix bits_per_pixel and bytes_per_line When the depth of the Xephyr server matches that of the host X server, Xephyr simply uses the buffer associated with the XImage as its framebuffer. In this case, it is correct to get the bits_per_pixel and bytes_per_line values returned from hostx_screen_init() from the XImage. However, when the depth doesn't match the host, Xephyr uses a private framebuffer that is periodically copied to the XImage. In this case, the returned values of bits_per_pixel and bytes_per_line should be those of the private framebuffer, not those of the XImage.

[Desktop-packages] [Bug 635523] Re: Xephyr crashed with SIGSEGV
Sebastian Heinlein, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ . If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report: apport-collect -p xorg-server REPLACE-WITH-BUG-NUMBER Please note, given you already have done this in a prior release, performing this on a release prior to Trusty would not be helpful. Thank you for your understanding.
