OK, I'll try to disable them, and we'll see if it changes anything.
This is now tracked as
https://labs.riseup.net/code/issues/10808.
Not sure if I can easily disable that boot animation, and to be honest
I won't focus on it initially, since it's a once-per-boot annoyance,
that does not impact UX once the desktop is started. That specific
animation might also, quite simply, be slow because at that time, the
system is doing *lots* of setup work that includes heavy CPU and
I/O usage.

OK. The good news is that I have access to a X200 so I can test there.
I'll also check if one can allocate more memory to the graphics
adapter, perhaps it could improve things a bit.
How much RAM in that X200?

Thanks. I guess our frontdesk will forward me the debugging info you
sent us so I can check what's happening (there's not much I can do
without that info).

Yes, it would be sad if X200 -class hardware, provided it has enough
RAM, was not usable in Tails anymore already. (It will happen some
day, but right now feels too early.)

FYI older versions of Tails don't ship a desktop that uses moderately
advanced graphics functionality (OpenGL), while GNOME Shell does.
Quite possibly, these "other distributions" don't rely on such
features either. If video drivers were outdated or buggy when it comes
to OpenGL handling, one would not notice it on older Tails, and
possibly not on other distributions. That's where my hypothesis that
drivers may be at fault came from.

Happy new year for you too! :)
