X_CreateColormap error rdesktop, xlock on 3 head nvidia display
 
I've seen a few postings with some similar issues, but I haven't seen any solutions yet. I get the following errors:

> xlock
X Error of failed request: BadValue (integer parameter out of range for operation)
Major opcode of failed request: 78 (X_CreateColormap)
Value in failed request: 0x0
Serial number of failed request: 64
Current serial number in output stream: 70

> rdesktop -u <user> -d amr -a 24 -g 3100x1100 -r sound:remote <machine>
X Error of failed request: BadValue (integer parameter out of range for operation)
Major opcode of failed request: 78 (X_CreateColormap)
Value in failed request: 0x0
Serial number of failed request: 7
Current serial number in output stream: 8

I don't get the errors when running in dual monitor mode.

Any ideas?

Thanks,

# Three possible sources for finding the BusID of the video cards

### Video Cards entry in /var/log/XFree86.0.log
#(--) PCI: (11:3:0) nVidia Corporation NV34 [GeForce FX 5200] rev 161, Mem @ 0xbc000000/24, 0xb0000000/27
#(--) PCI:*(64:0:0) nVidia Corporation unknown chipset (0x00fe) rev 162, Mem @ 0xb9000000/24, 0xc0000000/28, 0xba000000/24

### Run hwinfo --pci |less and then search for nvidia or whatever video card you are using
# AGP Video Card
# SysFS ID: /devices/pci0000:00/0000:00:04.0/0000:40:00.0
# SysFS BusID: 0000:40:00.0

# PCI Video Card
# SysFS ID: /devices/pci0000:00/0000:00:03.0/0000:01:00.2/0000:0b:03.0
# SysFS BusID: 0000:0b:03.0

### Change the 40:00.0 to decimal and enter this as the BusID, 64:0:0
### Change the 0b:03.0 to decimal and enter this as the BusID, 11:3:0

### Run lspci do the same thing as the hwinfo section above

The problem went away when I disabled xinerama. Of course, this gave me three separate desktops, which I don't want. I was able to use Twinview on two displays. So at the moment, I have two displays sharing a desktop and the third dislay with it's own. This current configuration does not seem to show the x_createcolormap issues, but it is not exactly what I was looking for.
