X windows:

	(I have an ATI-PCI Mach-32 accellerator with 1Mb memory)

This always takes more time than you think, in fact can be the most
problematic part of a Linux installation. It's one of the more
challenging things when you install LINUX for the first time, the
largest amount of questions on the newsgroups is about installing X
windows. Part of this is due to enormous degree of configuration options
that come with the current hardware (monitors, graphics accellerators). 

Also, some HOWTOs or books tell you to make a template of the XF86Config
file with the "ConfigXF86" program, but I've now heard several times
from people they had more success with the xf86config program. Also, run
the SuperProbe program to see if it comes up with some good suggestions.
Also be sure, if your monitor is a multi-sync, to enter a wide enough
range setting for the horizontal and vertical syncs, this way the X
server can most likely find more modes. It did for me.

The middle mouse button: Although my mouse worked fine in 'Microsoft
Mode' I could only talk to the middle mouse by emulation (there is
an option for this in the XF86Config file). However, it really becomes
awkward to have to hit those left and right mouse buttons at pretty 
much the same time. So here was my fix:

Although not installed within slackware, I found the relevant
information in the manual page of XF86Config(4/5). Here is what worked
for me (I have a 3-button noname mouse on a serial port that works fine
as Microsoft in emulation), but as usual, your mileage may vary.

Section "Pointer"
    Device "/dev/mouse"
    BaudRate 1200
    SampleRate 150

# Old:
#    Protocol "microsoft"
#    Emulate3Buttons

# New: (this will give access to the middle mouse button)
# some people don't need ClearDTR, others also need the other Clear...)
    Protocol "mousesystems"
    ClearDTR
EndSection  



I've heard from somebody else, for whom this didn't work, that they
had to hold the left mouse button while starting up X (with startx),
and that brought the middle mouse button (in mousesystems protocol) to 
live!

What I haven't gotten to work yet:

- 16 bit color. It's supposed to be able to, perhaps not with my 1Mb
  memory.  Somebody claimed that, except for the Cirrus cards, SVGA
  servers only work in 8 bits mode.
