Hi I'm using VNC to run an application called XWinNMR on a SGI. As I got it, accessing applications from a SGI requires 8 bit color. My local RH8.0 laptop runs with 24 bpp. Using the "vncserver -depth 8 -cc 3" options should get Xvnc going with 8 bpp with Pseudocolor. Many on this mailing list have reported that this works well. My problem is that the program still have problems displaying the colors. The colors look ok, but are flickering on the screen. Starting vncviewer tells me that I'm using Truecolor (!): ---------- [tormod@pc-52-161 tormod]$ vncviewer VNC server supports protocol version 3.3 (viewer 3.3) VNC authentication succeeded Desktop name "tormod's X desktop (pleiades:1)" Connected to VNC server, using protocol version 3.3 VNC server default format: 8 bits per pixel. Colour map (not true colour). Using default colormap which is TrueColor. Pixel format: 32 bits per pixel. Least significant byte first in each pixel. True colour: max red 255 green 255 blue 255, shift red 16 green 8 blue 0 Using shared memory PutImage ---------- But running "xdpyinfo" from Xvnc tells me that I'm using Pseudocolor ? The question is: Am I running Truecolor or Pseudocolor ? If I am _really_ using Truecolor, can I override the default ? If I am _really_ running Pseudocolor, I assume the problem lies within the XWinNMR program. Here's the output from xdpyinfo: > name of display: :1.0 > version number: 11.0 > vendor string: AT&T Laboratories Cambridge > vendor release number: 3332 > maximum request size: 4194300 bytes > motion buffer size: 256 > bitmap unit, bit order, padding: 32, MSBFirst, 32 > image byte order: MSBFirst > number of supported pixmap formats: 2 > supported pixmap formats: > depth 1, bits_per_pixel 1, scanline_pad 32 > depth 8, bits_per_pixel 8, scanline_pad 32 > keycode range: minimum 8, maximum 255 > focus: window 0x80000e, revert to PointerRoot > number of extensions: 7 > BIG-REQUESTS > MIT-SHM > MIT-SUNDRY-NONSTANDARD > SHAPE > SYNC > XC-MISC > XTEST > default screen number: 0 > number of screens: 1 > > screen #0: > dimensions: 1600x1000 pixels (542x339 > millimeters) > resolution: 75x75 dots per inch > depths (1): 8 > root window id: 0x25 > depth of root window: 8 planes > number of colormaps: minimum 1, maximum 1 > default colormap: 0x21 > default number of colormap cells: 256 > preallocated pixels: black 1, white 0 > options: backing-store YES, save-unders YES > largest cursor: 1600x1000 > current input event mask: 0xd0001d > KeyPressMask ButtonPressMask > > ButtonReleaseMask > EnterWindowMask > SubstructureRedirectMask > PropertyChangeMask > ColormapChangeMask > number of visuals: 1 > default visual id: 0x22 > visual: > visual id: 0x22 > class: PseudoColor > depth: 8 planes > available colormap entries: 256 > red, green, blue masks: 0x0, 0x0, 0x0 > significant bits in color specification: 8 > bits >
