You can try a site like justwatch.com to see if the film is available on a streaming sire you could use.
You can also search for rentals online so you can pay for it.
You can look on eBay or similar for cheaper second hand copies.
Or piracy.
Ctrl + alt + backspace is the shortcut for killing X (which manages the desktop display) which will then restart.
This is the closest equivalent to the windows shortcut which restarts the graphics subsystem. It does not restart the drivers on windows, instead it reinitialises the display after flushing things.
However note that In linux, killing X will also kill all the programs running which depend on it. You will essentially restart your entire session. This is due to how X works and there isn’t an alternative.
Note some distros disable the shortcut be default now and you have enable it first. You will need to google your distro. I believe Ubuntu disables it, and possibly Gnome on all systems? I use neither, that is just from googling so may be wrong.
I am not aware of a Wayland equivalent.
You can also switch TTY using (Ctrl + alt + F1 to F8) to switch to a different “teletypewriter” - basically a full screen terminal display. You can login and then run commands including killing X and even restart the graphics drivers here. You could make a script that does this which you can run in a TTY if needed. You can’t restart graphics drivers while X is running on the GPU; X has to be killed first.
A well written summary of the finales plot and its flaws. Its full of spoilers in case people haven’t see it yet.
Personally I think Doctor Who needs a long rest and a fresh start if it returns. I’d even suggest a hard reboot.
This current season has looked good but been a mess, and the finale is an incoherent mishmash of ideas and set pieces. There is far too much fan service and far too many ideas being crammed in that it just doesnt make sense.
The show has been in trouble for years. Both Ncuti Gatwa and Jodie Whittaker were good actors ill served by the writing. Peter Capaldi was also a good actor served by uneven writing but the show was still good.
Now its just a mess with convoluted plots, far too much fan service, and an inability to make an over arching season long plot work. Judging by the finale Gatwa leaving was probably unexpected and Billie Piper’s casting seems like a desperate stop gap while RTD decides what to do next (in the 2 year gap already expected because he is making a spin off series this year into next).
I wouldn’t be surprised if the Disney deal comes to an early end and Doctor Who is shelved for years while they decide what to do next.
