Hi all,
I just brought my machine up with FreeBSD-2.1.0-RELEASE. it is a
pentium 133, 16MB memory, sony 17se monitor, and ATI mach64 framebuffer.
I was told [locally] that the XFree86 server distributed with FreeBSD
would not work with this monitor/framebuffer, so I loaded the X Inside
Accelerated X server we have. I start up the X server in 1024x768
8bit color mode and the X server immediately occupies over 10M of memory
[this is 75% of my real memory! :-[ opening an emacs and netscape
immediatly puts me into thrashing mode :'(
I'm wondering if there's anything I should check to reduce memory usage?
is there another XFree86 X server that will support this monitor/framebuffer
with less memory usage? is FreeBSD+X11 usable on a 16M machine?
here's a 'ps' just after xinit with only the default xterm up:
USER PID %CPU %MEM VSZ RSS TT STAT STARTED TIME COMMAND
root 11006 11.7 74.6 1812 10576 ?? S 3:11AM 0:01.40 /usr/X11R6/lib/X11/AcceleratedX/arch/FreeBSD/Xaccel :0
I've attached a copy of my /etc/Xaccel.ini file and a xdpyinfo dump
in case any of that is useful in debugging my setup.
thanks for any suggestions!
danny
