I posted to the newbie list about my troubles about a month ago and
didn't get much help.
I had xfree86 3.3.6 working *ok* on my little compaq elite lte 4/75cx
under Debian Potato. I could get 640x480 at 8 bits per pixel.
When I went to xfree86 4.2 (upgraded to Woody), I had trouble at first
getting xfree to display anything but 340x240. Then I figured out that
it would only do 640x480 at 4 bits using the vga driver.
When I asked about this on the newbie list, the only answer I got was
"try vesa or frambuffer" without any other explanation.
I took me a while to figure out what that ment and to get a kernel with
all the framebuffer support setup right.
Now, here's what I get:
When I set the xfree driver to vesa in XF86Config:
(II) VESA(0): initializing int10
(II) VESA(0): Primary V_BIOS segment is: 0xc000
(II) VESA(0): VESA BIOS not detected
(II) UnloadModule: "vesa"
(II) UnloadModule: "int10"
(II) UnloadModule: "vbe"
(II) UnloadModule: "vgahw"
(II) Unloading /usr/X11R6/lib/modules/libvgahw.a
(EE) Screen(s) found, but none have a usable configuration.
Fatal server error:
no screens found
So much for vesa. I kinda figured this laptop was too old for vesa support.
When I set the driver to fbdev and use the same resolution settings that
worked for vga (640x480x4):
(II) FBDev: driver for framebuffer: fbdev, afb

Sometimes I get a "Caught signal 8. Server aborting". Signal 8 is a
floating point exception. That baffles me.
When I set the driver to fbdev and request a 640x480x8 resolution, I get:
(II) FBDev: driver for framebuffer: fbdev, afb
(II) Primary Device is: ISA

Sooo... Does anybody have any other suggestions, or am I stuck with 4
bpp if I want to use 4.x on this machine.
