[MIFit] on Ubuntu 10.04 x86_64 and ATI Radeon display drivers

[shekum]

Hello,

I recently downloaded MIFit for Linux and the program runs well apart
from the Canvas areas and Navigator canvas sections of the GUI not
displaying correctly. MIFit loads the structures perfectly fine, but
when it comes to displaying the structure in these two areas, MIFit
will temporarily display the structures as I click and rotate/zoom/
translate but will stop displaying the two sections, after a variable
period of time.

I believe I've narrowed down the problem to something that has to do
with the ATI graphics drivers because when I uninstall them proand run
MIFit and Ubuntu in the low graphics option, the problem disappears.

Do you have any suggestions, apart from trying various drivers because
I've already tried it out with the proprietary fglrx driver, as well
as RadeonHD (MIFit doesn't even start) as well as ATI's new driver but
none of them work as well as running Ubuntu in the low graphics mode.

Thanks,
Shekum

What happens if you close the Navigator before loading a file? Does it
still stop displaying after a period of time?

If the problem goes away with the Navigator closed, I think that would
be the best solution. If not, I can create a preference setting which
will disable it completely.

I've tried closing all windows, the navigator, the ramachandran plot,
the log and model windows, but I believe it's a video driver thing,
and I'm going to wait to see once ATI release the stable/tested
version to see if it'll be fixed. Till then, I've begun using the
Windows version of MIFit, and I haven't run into display issues there.
However, for some reason the electron density rendering seems to be
different from what XFit does, and models fit in XFit loaded onto
MIFit tend to cause different Fo-Fc calculations. Do you know what the
reason for that may be?

Thanks for your help!

How is the electron density rendered differently than XFit, and how are the Fo-Fc calculations different?

I do not have XFit and therefore can't do a comparison. If there is a defect in MIFit, please let me know the details and I will attempt to correct it.

Could we use email instead? That way I can also forward you jpegs of
what I'm talking about.

Please use the issue tracking on the MIFit project web site: http://code.google.com/p/mifit/issues/list

You can attach jpegs to the issue report.

Thanks,
