Hi John,
I had struggled with this myself, and investigation revealed that it isn't
an R problem, but an X11 bug in Ubuntu. This is evident from plot(rnorm(10))
failing to perform. If you are seeing this, then it is because X11 does not
automatically detect Intel graphic cards. The solution is to edit your
xorg.conf file, changing it to something like (this is from my xorg.conf):
Section "Device"
Identifier "Intel Corporation Mobile 945GM/GMS, 943/940GML Express
Integrated Graphics Controller (rev 03)"
Driver "intel"
EndSection
Make sure you keep a copy of the original xorg.conf file while you're
experimenting.
Does this work for you? We can dig in deeper once we've identified where the
problem is.
