The last couple of weeks I have started to get random crashes of the X server - it dies with SEGV. It occurs every few days or so and has no obvious trigger. I think it started about the same time as the update to 3.5 kernel (tho may be unrelated). Bug filed here: https://bugs.archlinux.org/task/30921 When it happens the X session ends and I am back at kdm prompt. gene
