>>Hello linux-user,
>>However I can get Xwindows to run on my computer. I use Xfree1.0Y (I read somewhere that Xfree1.2 will give better result with the trident, so somebody told me I needed to downloaded Xbin1.2, but this was aparently not Xfree1.2). The server reports a trident with the supported clocks, the monitor shows at first a scrambled picture than a black screen. The server does not respond to the ctrl-alt-backspace and does not hang the computer either. Do I use the wrong clocks or is the server not properly i
1. Xfree1.0Y was an alpha test release never meant for public consumption.
Many bugs (server numlock, etc) have been fixed in Xfree1.1 and Xfree1.2,
and many new features have been added (ie, switching to multiple
graphics / text virtual consoles, banked mono server for mono
to 1600x1200, etc)
2. The clock detection code is *not* reliable, and is highly
dependant on how loaded the system is. So, instead you
should use the clocks given in the trident doc file.
3. The *SAMPLE* Xconfig file in /usr/X386/lib/X11/Xconfig has a number
of different clocks specified for each mode. The highest one will
be used if there is a conflict, and if your monitor can't sync to
it, it won't work. Try commenting out the higher-clocked lines.
4. Also, comment out some of the other resolutions. Try your
BASIC, VESA 640x480 first.

Xfree through 1.2 doesn't work with Tridents in interlaced mode,
later beta / alpha releases do work, and no I don't have the
addresses as to where to get them. Join the X11 channel on
Linux-activists.

No. The "minimum requirement of 8megs" is merely a sugestion.
In 8M, you won't see a lot of paging and response will be
very good.
Before I bought more memory, I ran X11 (mono, although the color
server would run) in 4M of memory.

Linux doesn't run out of swap gracefully. It gets slower and slower and
slower until it dies. IMHO, you need at least 12M of virtual memory -
make a larger swap partition, or add swapfiles (these are slower, with
only 4M of memory you'll do some paging and you want this to be fast),
After you have more swap, you'll be able to run X in either color or
mono, but I wouldn't recommend the former.
Hints on getting it to run fast :
1. Use a swap partition, not a file.
2. Make a kernel tuned for your system - you can eliminate
50-100K of unpageable kernel.

That's irrelevant. It is MUCH faster though :-)

Add more swap space, and it will work fine.
