when I first read your post, I thought it doesn't apply to my linux
installation. But then I tried to run X with -bpp 24 and just got
strange colors (apparently, it's only 8, 16, and 32 bits that are
suppoted by my card/monitor/linux combo).
Now with -bpp 32 I get the same error message as you when starting IDL.
Since linux is spreading more and more, it may be helpful to offer the
solution in the newsgroup, therefore, I kindly ask the abovementioned
experts to help me out as well. Please find the relevant xdpyinfo output
attached below. IDL does wok with color depth 8, but then I only have 62
colors even when nothing else is running (using fvwm2). With netscape
started prior to IDL) you get into that colortable-not-updated problem
discussed in a different thread.
Thanks,
Martin.
