I have the following problem: When rotating molecules or volumes the whole computer freezes for a while. Sometimes recover and will freeze again after a few more molecule movements. Sometimes the whole system crash, the blue screen appear and a whole reboot is needed. The problem most likely is graphic card related. I did reported it before and was suggested to change the driver. I did but it did not solve the problem. My system currently is as follow: Chimera 1.2422 Windows XP service pack-2 Dell Precision 530 with Dual Xeon 1.4 GHZ processors and 1 GB RAM Graphic Card: NVDIA Quadro 900 XGL Video BIOS version 4.25.0027.05 ForceWare version: 78.01 Before I had: ForceWare version 91.36 So both of these video driver had problems. I wonder if anybody has experienced something similar and found the right driver. Thanks Hernando
Hi Hernando, I think we have a Quadro 900 XGL in the lab which has not caused the computer freezes you observe. I'll look when I am at the office tomorrow (Tuesday) and check which driver that machine is using. It is possible that the graphics driver problem is only seen on dual processor or dual core systems, because the processors can simultaneously contend for use of the graphics. I do not see any Quadro 900 XGL problems reported on our graphics driver bug web page: http://www.cgl.ucsf.edu/chimera/graphics/graphicsbugs.html#cards Tom
I have had similar problems on a macintosh G5 (dual 2.5 GHz, Nvidia GeForce 6800 Ultra DDL graphics card). It sometimes suffers from a progressive slowdown of command execution over 5-10 minutes of use and eventually becomes unusable. Save session, quit, restart program, restore session fixes the problem temporarily. Evan Sadler On 8/20/07 12:11 PM, "Tom Goddard" <goddard@cgl.ucsf.edu> wrote:

If there is progressive slowdown, then there might be a memory leak that we are unaware of. Please use chimera's Report a Bug dialog (in the Help menu) and replace the blue text "(Describe the actions that caused this problem to occur here)" with a description of what kind of data you're looking at and which tools and commands you use to manipulate the data. And please include your email address so we can ask for more information when we can't reproduce the bug (and let you know when it is fixed). Ideally, you'd attach a command script that replicates the bug, but some information is better than none. Greg Couch UCSF Computer Graphics Lab
Hi Hernando, I tested our Quadro 900 XGL graphics with Chimera 1.2422 with a map and PDB model (1a2p pdb and xray density ~170^3) and saw not problems in about 5 minutes of use. Tried both Linux (Fedora core 7) and Windows XP. The Windows driver version was Forceware 91.36 (7/12/2006). The Linux driver version was 96.31. The machine has a single Xeon processort, 2.8 GHz and video bios version 4.25.00.22.03. It is dual display. I noticed in Windows there are quite a few Nvidia "performance and quality settings" (right click on desktop, Properties, Settings, Advanced, Quadro 900XGL tab). Ours were set to use global driver settings and the defaults (restore button grayed out). Tom
Hi Tom, I changed the driver to 96.36 and it seems to work better. However, still the computer sometimes slow down and freezes for a while when moving a molecule (pdb: 1ii6) with the mouse. It seems to happen in particular when rotating the molecule with the mouse after zooming in (by clicking the right mouse button and moving the mouse). Thanks Hernando Thomas Goddard wrote:

Hi Hernando, I tried rotating, moving, zooming, coloring, sphere, wire, stick, ball and stick, ribbon on 1ii6 on our Quadro 900 XGL system and it never paused even briefly. Tom
Hmmm. Maybe is because my system has two processors?. In any case the problem does not seem unique to chimera. I tried GoogleEarth which also uses OpenGL and completely froze my computer. Hernando Thomas Goddard wrote:

Hi Hernando, You might find a solution by changing the Nvidia driver performance and quality settings. Right click on the desktop, select Properties, Settings, Advanced, Quadro 900 XGL to find these. Generally you would want to change the settings to lower performance. The bugs seem to usually be in the graphics driver optimizations, and perhaps your case is related to having multiple processors. Tom
Try running a memcheck on it for several hours. Or if you can reduce the speed of your RAM in the bios to the next slowest increment (e.g. from DDR400->DDR333). hsosa@aecom.yu.edu wrote:

Here is an update with the problem that I had with my nvidia Quadro 900 XGL running chimera and freezing the system. It was a hardware problem with the card (it seems that the fan was not working and something got burned ??). At the beginning only OpenGL applications such as Chimers or Google Earth were causing trouble freezing the system. Eventually display problems appeared all the time regardless of the application. I replaced the card (for an ATI Radeon 9550) and now everything seem to work fine Thanks for the previous suggestions Regards Hernando . Thomas Goddard wrote:
