I'm trying to capture a window image using xwd on a GLX window with overlays. I get the following error
[hancockd@robotics3 xwd]$ xwd > output.xwd
X Error of failed request: BadValue (integer parameter out of range for operation)
Major opcode of failed request: 91 (X_QueryColors)
Value in failed request: 0xc35e57
Serial number of failed request: 2111
Current serial number in output stream: 2111
Throught some investigation and modifying the xwd source code I believe the visual where the trouble occurs
is in the following visual
visual:
visual id: 0x3c
class: TrueColor
depth: 16 planes
available colormap entries: 64 per subfield
red, green, blue masks: 0x7c00, 0x3e0, 0x1f
significant bits in color specification: 5 bits
The problem seems that before the colors array is sent to XQueryColors it is using 64 as the number of colors.
The 5 bit colors only seem able to handle 32 colors. This visual is from an NVIDIA GeForceFX 1000 with the
NVIDIA driver. Is this a valid Visual configuration? Is this something xwd should handle? Is this something
NVIDIA should fix?
Any help would be appreciated.
