Re: [ccp4bb] COOT running slow after upgrading to CENTOS 6.4 from 6.3
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Dear Zhijie, this sounds like a graphics driver issue. You can use the command 'lspci | grep -i vga' to find out what graphics chip you have on the computer, and you should check /var/log/Xorg.0.log what driver is actually used. If it is an NVIDIA card and the system uses the nouveau kernel module, try and install the driver from the NVIDIA homepage.

Re: [ccp4bb] COOT running slow after upgrading to CENTOS 6.4 from 6.3
Hi Zhijie, our system administrator has warned me sternly against touching RHEL 6.4. The same might hold true for CentOS. I would be interested to hear from anyone running 6.4 successfully.

The computer with trouble have python upgraded to 2.7 from the python source code when it was running CentOS 6.3, could this be a problem?

[ccp4bb] COOT running slow after upgrading to CENTOS 6.4 from 6.3
Hello, We have a curious situation here: after upgrading CentOS 6.3 to 6.4, COOT runs slowly every time after the "go to atom" command is executed - every rotation of the molecules takes nearly 1 second to finish. But if the "go to atom" command is never sent then the speed is normal. A COOT running in a virtual machine windows XP on the same computer behaves OK though. It doesn't seem to be a conflict with the CentOS 6.4 either, because COOT on another computer with newly installed CentOS 6.4 runs perfectly fine. So I guess it might has to do with some libraries that COOT might use. The computer with trouble have python upgraded to 2.7 from the python source code when it was running CentOS 6.3, could this be a problem? Zhijie
