I just downloaded the latest 2.2.26 kernel for BL3 and tried it in BL3 and
BL2. Unlike David's 2.4.31 kernel, it does work with Xvesa. (I could not
test on this video card with plain X).

It has networking support. Mine does not (to save space).
Does Xvesa require networking support? If so, why?


zgv still does not work: mmap error in paged screen memory.

Since I have no USB devices that will work with 2.2.26,

You don't? Did you try your usb-storage device? Do you have
a non-storage device which does not work with 2.2.26?

I have no idea how to use a USB mouse in linux but will try ours if someone explains how. I did not try the camera because you said usb-storage did not work right, but I will try tomorrow if you want.


I will stick with 2.2.16 until someone can figure out the zgv
(svgalib) problem with 2.2.26.

The problem is with svgalib using an old mmap call, which has
been dropped in 2.2.26 (sometime before then).

Maybe the libvga and libvgagl from SW91 will fix svgalib in BL2,

They will.

Okay, I will install the svgalib package from SW91. I really need to get a few computers put back together first and fix a major scsi problem (three devices, all with problems, maybe caused by one bad device).


but zgv for BL3 is statically compiled and would need to be replaced.

Is there a dynamic zgv for libc5? Or a dynamic seejpeg? Doesn't SW4
have one?

Yes for seejpeg. I don't know about zgv. Why is the static version not working with the 2.4.31 kernel?

I could try using the static zgv with SW91 (live CD).

It will not work.

So the problem has nothing to do with how you compiled the kernel.


Maybe the later kernel simply dropped support for svgalib?

Nope. It works for me with a newer version of svgalib.

I also could not get lynx to compile for it.

Does lynx even work with svgalib?

I goofed, I meant ghostscript 8.50 not lynx. It compiled for X okay.

One could skip svgalib and use xli and links -g under X, which does work
with 2.2.26.

But it is larger.

Regarding David's 2.4.31 usb-storage kernel that won't work with svgalib
(zgv) or any form of X in BL2:

It might be a lot simpler just to use your small usb-storage kernel for
downloading pictures and reboot to the regular 2.2.16 (or 2.2.26 - if it
works with everything now on my computer).

I should have asked how often you need to transfer pictures. Would
you really need to use X/sound at the same time?

Not if I can get svgalib/zgv working so I can check that the photos are really there and not corrupted before I delete them from the camera.


Same problem with BL3 X-vesa, which is statically compiled (against
uClibC?). Unless David can compile a 2.4.31 kernel that will work with
the SW71 (and SW40) svgalib

I can't.

and X, and with Xvesa, and does not require a
later libc than SW81,

It will not require a new libc.

David, could you try out any kernel you compile to make
sure it works with Xvesa from BL3?

It will work if networking is set to Y.

The minimal kernel will be handy if it can be put onto a 2-floppy BL3 set to use on other people's computers. Does your kernel mount DOS and Windows file systems?

I will work on the svgalib upgrade.
And try 2.2.26 kernel with usb-storage devices (and maybe a mouse, but it is simpler to use the PS/2 adaptor).

David
