Hi Greg,
I know that doing anything with graphics within virtual machines is not always a brilliant idea, but I have seen Chimera work in VirtualBox and I wanted to get to the bottom of why mine doesn’t…
I’ve got the latest graphics driver on my host (and I run Chimera successfully on it anyway). I’ve run the commands you suggested, with the following output
$ gdb $CHIMERA/bin/python2.7

I guess the lack of libgfxinfo.so is fairly significant, and I assume that the result from bt is all part of the problem?

Hi Chris,
So what are you trying to do with Chimera inside a virtual machine? Presumably, you're not trying to use it graphically because virtualized graphics performance is usually abysmal. Chimera benefits immensely from direct access to the graphics hardware. So
that leaves using Chimera as a server, and for that the headless version of Chimera is usually better -- the headless version uses a software implementation of OpenGL and thus avoids any driver issues.
That said, this bug is still likely to be related to OpenGL support in VirtualBox. Make sure the computer that VirtualBox is running on has an up-to-date OpenGL graphics driver. It doesn't matter what VirtualBox does if the underlying system has a bad graphics
driver.
To confirm that the bug is in the graphics driver, get a backtrace of where the error occurs by using gdb as follows in a Terminal window (and assuming there is a symbolic link to the chimera binary on your path):
% export CHIMERA=`chimera --root`
% export LD_LIBRARY_PATH=$CHIMERA/lib
% gdb $CHIMERA/bin/python2.7
(gdb) break_exit
(gdb) run $CHIMERA/share/__main__.py --debug
(gdb) bt
The '%' and '(gdb)' parts are the shell and gdb prompts, respectively. The output from the bt command will probably be in Chimera's molecular drawing code (as opposed to drawing the UI). If you need help interpreting the chimera backtrace, you can send it
to me.
HTH,
Greg

Hello all,
I'm trying to run Chimera on VirtualBox. The installation completes fine, but when I try and run the program (cd to the bin directory and run
./chimera) I see
X Error of failed request: BadDrawable (invalid Pixmap or Window parameter)
Major opcode of failed request: 72 (X_PutImage)
Resource id in failed request: 0x480006a
Serial number of failed request: 1382
Current serial number in output stream: 1388
I've tried enabling / disabling hardware virtualization & 3D acceleration, but to no avail. Although people do seem to have problems with chimera on a virtualbox, it normally seems to be a problem with OpenGL, which this doesn't seem to
be.
Has anyone seen this error before? Is there anything else I'm missing? I can’t even work out if it's a hardware, VirtualBox, or OS problem…
System:
VirtualBox 4.2.4
Guest additions 4.2.4
Guest OS: Ubuntu 12.04
Host OS: Windows 7 professional
Thanks in advance!
Chris
