Dear Jorge,
I got the same problem several month ago, coot works fluently in a virtual
machine of centos 5 or ubuntu but not in a host machine of the same OS.
Just 2 days ago, in order to run program more quickly, I convert the virtual
machine of Ubuntu 14.04 to a physical machine.
And it was amazing that coot ran smoothly, no matter space bar translation or
rotation.
I'm sure that this was caused by the hard drivers problem.
So, try to update your OS, the Linux core may update and support your graphics
card. Or you can search Linux hard driver of your machine.
By the way, my coot version is 0.8.1.
Best!

Dear all,
My machine has openSuSE 12.3, a lenovo ideadpad with 8 cores (4 are
virutal) and 8 GB memory.
For a number of coot versions in it (including the newest one), coot
answers slowly to rotating, but specially the space bar translate is even more
slow (from residue x to x+1 etc.).
Curiously, in either CentOS or even openSuSE in oracle virtualboxes (under
this openSuSE host), to which I liberate only 1 cpu and only 1 GB memory, it
goes much faster, at a very reasonable speed. How could be that? In principle I
thought that the multicore configuration of the host machine might be the
culprit.
So, for coot tasks, I have been using the virtual machine, but that is
impractical.
The closest to this problem I found was
https://www.mail-archive.com/coot@jiscmail.ac.uk/msg03787.html , but I could
not devise any trial to solve the problem. Even trying the
http://www2.mrc-lmb.cam.ac.uk/personal/pemsley/coot/web/docs/coot.html#Slow-Computer-Configuration
configuration did not solve the problem satisfactorily. I tried to
search wider, but could not find other suggestions. Should you have one, I
would be glad to try. Sincerely yours,Jorge
