Hi all, I just did a clean install of FC20 on an AMD dual core system. I opted for the 32 bit version, as these workstations are used for multiple things (and I find that it’s just easier most of the time, though 64 bit may be where I need to go eventually). I installed Chimera Version 1.9, Build 39798 on Fedora FC20. When running chimera, my computer constantly freezes. Obviously I’m missing something. I’m not doing anything fancy - I use Zalman monitors connected to generic video cards. I can run coot fine - I don’t know about ccp4i (it seems to run, but I haven’t challenged it in any way). As long as Chimera is not running, my computer runs nicely. I have flash/etc… working fine. Any thoughts on where I should start here? This happens on 3 separate systems (that are essentially the same, but not identical clones). I’m assuming I missed something obvious in the install. Thanks Dave
