I assume you mean how to increase the number of bits per pixel, which would in fact result in a larger colormap and stop the sudden color-switch when netscape loads itself up. X defaults to eight bits per pixel (bpp) - you can change that default, but first pick a value for bpp that you're comfortable with. To test values, switch out of X to a text console and do: startx -- :1 -bpp n Where n is one of 8, 15, 16, 24, or 32. Note that the higher you go in terms of bpp, the worse your resolution gets. Test out this X screen (this screen, by the way, will open on virtual console 8, so you can use Ctrl-Alt-F8 to switch to it; Ctrl-Alt-F7 gives you your regular X session) Once you find a value for bpp that you like (I use 16 bpp at 1152x864 quite happily with a mere 2 MB of video memory) add the following line to /etc/X11/XF86Config, in the "Screen" section, right after the Driver line that mentions which X server you're using: DefaultColorDepth n where n is the value you picked. For example, since I use the SVGA server, a piece of my /etc/X11/XF86Config looks like this: Section "Screen" Driver "SVGA" DefaultColorDepth 16 Device "Primary Card" Monitor "Primary Monitor" Then just restart the X server (If you're using xdm, logging out of your X session and doing a Ctrl-Alt-BackSpace should do the trick) -- TO UNSUBSCRIBE FROM THIS MAILING LIST: e-mail the word "unsubscribe" to [EMAIL PROTECTED] .
