I looked into /var/log/Xorg.0.log and found that Xorg's automatic configuration was indeed working just fine with my card. But then it hit me that I was using a modularized kernel I had built specifically for my old laptop which did not include the video module for the card on the system I was testing all this with...I'm very embarrassed to say
. So, I promptly put in a more adequate modularized kernel and now, with the right kernel module for the card, TC (or more precisely, MC + Xorg) booted up with a working mouse pointer (which didn't have before, with the missing kernel module), but still no icons. Looked in /etc/sysconfig and - of course! - no icon file in there (due to the scatter mode install). So, all I had to do at this point was to create an /etc/sysconfig/icon file with text "wbar" and - voila'! - now Xorg works perfectly fine on this system.
Scatter mode as you might say is perhaps the hard way to go about it, but let me tell you, it's the only way to to look under the hood and really learn how the system works...and there's that great feeling of exultation when you do and are able to overcome little obstacles, one by one.
Very much worth the effort, IMO. I'm pretty sure you can relate to it.
So, all I have to do now is to recreate those changes listed at reply # 27 to achieve the end result I was aiming for. Let's see how it goes... The more I learn about TCL, the more fascinating and elegant I find it to be...
