From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

You may be pretty heavily discounting the influence of gravity.
I do not think that risk of collision based on current trajectory is the only thing to consider.
I'm not an astronomer so I might be wrong, but wouldn't the gravitational influence of stars from Andromeda in the Milky Way still be negligible, again because of much empty space there is?
Gravity is not just attraction to the closest thing but also the heaviest thing.
As the galaxies “pass” each other, all stars will be attracted to the dense cores of each galaxy. That is going to change the trajectory of individual stars and, as an aggravate effect, the overall shape and distribution. Unless the galaxies are aligned on the same angle, this is going to drag stars off the primary plane.
As the galaxies approach, the arms will stretch out to each other. As they pass through each other, the planes will tug on each other, and after they “exit”, the arms will reach back.
All this new motion will disrupt the natural shape and trajectory of the galaxy as a whole. Depending on the momentum, it could get pulled back and the whole process could happen again ( and again ) with greater disorder each time.
