Could you provide more information on your configuration,
like graphics card, ... also try disabling DRI (comment out
the line about dri in xorg.conf).

Also remounting you /var partition with sync option might
help to get further information in the log.

Please use xorg at lists.freedesktop.org insted of
xorg-modular. It's no longuer alive maybe we should kill it.
It was used during modularisation of Xorg.
