Thanks Carlos Contreras-Martel and Lu Zuokun for pointing me to check
graphic driver problems (or update them from the vendor, by the way,
controller model Intel HD 4000). Taking some time with this today, I
still feel I will have to study further before making changes.
This poses me yet other question, though maybe it escapes the discussion
list scope, that I must search further: how (and where) different are
the resources used by the virtual machine compared to the host machine,
such that this graphical behavior is different.
Yours,
Jorge

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

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
