[sane-devel] Fwd: Re: scanning only 75 dpi

[Gerrit Borgers]

hello

I tried to install "sane-utils 1.0.21" as *.deb (because of the version 
number) instead of "sane 1.0.14-9" as I found in the "synaptic": package 
adress:

https://launchpad.net/ubuntu/natty/i386/sane-utils/1.0.21-9ubuntu1

without success (no progress in installing for 1/2 h

+++++++++++++++++++++++++++++++++++++++++++++
here my results from this morning:

Ubuntu 10.10 Kernel 2.6.38-8

Ubuntu 11.04 Kernel 2.6.35


SuSE 11.3 Kernel 2.6.34-12

SuSE 11.4 Kernel 2.6.37-0,5


Printer/Scanner Lexmark X1270 (2 different printers)

** 300 dpi runs "interlaced"

* may be similar with Lexmark X11**, lexmark X12**



    *

      Downgrading xsane .998 to xsane .997 on ubuntu 11.4 with *NO
      POSITIVE* result

    *

      scan.logs are all different and big (~ 14000 lines)

    * The "connection" between
      - "u 11.04", "s 11,4" and
      - xsane .997, xsane .998, skanlite
      has changed, maybe caused by different memory management between
      xsane / scanlite
      and Linux
