This archive contains answers to questions sent to Unidata support through mid-2025. Note that the archive is no longer being updated. We provide the archive for reference; many of the answers presented here remain technically correct, even if somewhat outdated.

Li, You have: default visual id: 0x23 visual: visual id: 0x23 class: TrueColor depth: 16 planes available colormap entries: 64 per subfield red, green, blue masks: 0xf800, 0x7e0, 0x1f significant bits in color specification: 6 bits It appears you are running a Xfree86 server, so I'm guessing Linux. You can configure your depth through the "linuxconfig" script and select the 8 bit (256 colors) mode. Also make sure you are not running GNOME. Use KDE, TWM or FVWM.
