Hello,

I've just installed a sunblade-150 with solaris-10. Problem is with X-
Display being veryslowto scroll even the terminal in windowing
environment with half the screen displaying old contents and rest with
new and after 1-2 seconds it goes normail when I scroll. Can someone
help me how to fasten the fresh rate or get rid of this veryslow
scroll issue in X

        I don't have a SB-150, nor any experience with ones displaying
that slow behavior, but I have a few questions which might help others
lead to a solution.

1) You answered this one -- the memory.

2)      What window manager are you using?  Solaris 10 gives the
        choice of Gnome or CDE (before going into what is packaged
        in the Software Companion CD).  Of the two, Gnome is much more
        resource hungry, so you might improve the speed by switching
        to CDE -- in spite of their warnings that CDE might go away
        soon.  It won't go away from your current install at least.

3)      What framebuffer are you using?  I'm not sure whether the
        SB-150 has a built-in framebuffer, or whether you are using one
        in either a UPA slot or a PCI slot.

        O.K.  Looking at my FEH, (which only covers the SB-100, not the
        SB-150) it appears that there is a built-in framebuffer, and
        only  PCI slots for other framebufers.

        The choices appear to be (from an on-line FEH page for the
        SB-150):

        XVR-100 Graphics Accelerator (64MB)
        XVR-600 Graphics Accelerator
        XVR-500 Graphics Accelerator
        PGX64 8/24-Bit Color Frame Buffer
        XVR-100 Graphics Accelerator (32MB)

        With the last three described as "supported by can no longer be
        ordered with the system.

        I suspect that any of these would be faster than the built-in
        one which is what I suspect that you are using.

4)      What resolution are you set to?  fbconfig lets you select the
        resolution (among other things) and you may get faster operation
        by selecting a lower resolution.

        Good Luck,
                DoN.

O.K. You've answered the questions of how much memory and the
unasked one of how fast a CPU, but not what window manager (Gnome vs
CDE) and what framebuffer (graphics card). I'm not sure whether
"prtfru" will work on a SB-150 to tell you -- and you have to interpret
which Sun part number is the framebuffer. (Or are you using the built-in
one -- the VGA connector on the system board instead of a VGA or 13W3 on
a PCI card somewhere in the system.

If all else fails -- open the box, pull the framebuffer, and
note the 501-???? or 370-???? barcode number on it. It looks as though
prtfru only identifies the system board, the CPUs, and the DIMMs, and
ignores the PCI cards -- at least without options.

If you need the number of a PCI framebuffer translated to a
model -- post it and whe can probably look it up. (Or it likely will
match one of the five which I posted -- except that I didn't bother
typing the barcode numbers when I had them in front of me. :-)

Note that the barcode number may or may not have the '-' after
the first three digits, and there will be more digits after the next
four. Thost last digits make up the serial number of the card.

If you're running Gnome as your window manager, log out and log
back in selecting CDE instead and you will probably find it to be a much
faster system.

Good Luck,
DoN.
