Dear Coot community,

I encountered some problems using Coot on fedora core 10. I installed the
binaries, and upon starting, the system crashed just in the moment when the
Coot window appeared. I have a ATI radeon X1650 graphics card. When I switch
from the standard radeon to the ATI fglrx graphics driver, the system does
not crash anymore, but Coot quits with the following error message:

The program 'coot-real' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadRequest (invalid request code or no such operation)'.
  (Details: serial 661 error_code 1 request_code 143 minor_code 19)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the --sync command line
   option to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)
coot-exe: "/usr/local/bin/coot-Linux-i386-fedora-10-gtk2-python/bin/coot-real"

core: #f
No core file found.  No debugging

Any hints how to solve this problem?

coot-version: /usr/local/bin/coot-Linux-i386-fedora-10-gtk2-python/bin/coot-real platform: /bin/uname

when you say "the system crashed" I understand that this means that the operating system ceases to work, with a kernel panic message or similar on the console, X server dead, and not pingable (and no ssh login) from other machines? If so, then this is not a bug in coot, but rather in the "standard radeon" graphics driver. As this driver is probably a part of FC10, you could try to find a fix by looking into Fedora's Bugzilla, or posting on the Fedora mailing lists. It is hard to say whether this bug is related to the crash of coot when using the ATI fglrx driver. Check out the ATI pages ; link given at It would be nice if you could improve that section of CCP4 wiki based on what you find out. P.S. As you know we've been using NVidia graphics cards in my lab, without such problems ...
