Weyland is the project to remove X11 from Linux.
http://en.wikipedia.org/wiki/Wayland_(display_server)
Ubuntu chiefs have said they support Weyland and aim to include it
in the next release (April 2011 == version 11.04 == Natty Narwhal).
Fedora developers apparenly said that they are likely to adopt
Weyland too.
I don't know if packages in R such as rgl would need changing to
work with Weyland, or perhaps R itself, if at all. However it seems
that Linux is moving away from X11.
If X11 calls aren't supported in Wayland, then rgl won't work there.
The Wayland people will need to write a replacement for the glx
interface to OpenGL, and an rgl user will need to write the code to use
this in rgl (i.e. equivalents of the x11gui.* and x11lib.* files in the
rgl sources). rgl is designed to work on multiple systems (currently
Windows, Cocoa in OSX, and X11), but it's not trivial to implement a new
one.

Mentioned it here because the issue in this thread appears to be
X11 specific. X11's days seem to be numbered if I understand
correctly.

I hope those names mean something to Rainer, because they mean nothing to
me.

Hi
rgl crashes my R session, when resizing the rgl graphic window.
I am using Ubuntu Maversick, with dual monitor setup. If I disconnect
one monitor, I can resize it "a little bit", but it still craches if I
enlarge it to much.
I assume that the problem has to do with allocated graphic memory in
the
kernel, but why is R crashing completely, and not evn giving the usual
crash options?
Cheers,

After executing
library(rgl)
example(rgl)
and resizing the graph window, R crashes witrh the following message:
drmRadeonCmdBuffer: -22. Kernel failed to parse or rejected command
stream. See dmesg for more info.
from dmesg:
[ 7349.471959] [drm:r100_cs_track_check] *ERROR* [drm] Buffer too
small
for color buffer 0 (need 413696 have 262144) !

(256 4 0 404)
[ 7349.471967] [drm:radeon_cs_ioctl] *ERROR* Invalid command stream !
Those messages look like they're coming from your graphics driver,
not
from R. So rgl may be doing something it shouldn't do, but you'll
probably have to diagnose what that is. It's unlikely to be
reproducible on another system.
That's what I fear as well - could you give me any tips on how to
proceed to identify the problem?
It might help to know which line of code in rgl actually triggered the
error, but debugging X11 code is tricky. The function that likely
triggered the problem is X11WindowImpl::setWindowRect in
rgl/src/x11gui.cpp; it makes calls to X11 functions that do the actual
work.
