Ubuntu 20.04 simple-scan brightness and contrast controls have no effect

[tkbuntu]

Ubuntu 20.04 simple-scan. The Brightness and Contrast controls have no effect. No matter how I position the sliders the scan image remains the same, ie, a dark background. It is as if the controls are not 'connected'.

Ubuntu 20.04 is up to date. The scanner is a Cannon LiDE60.

I have 19.10 in another partition. Simple-scan works as expected. Ditto for 18.04.

Regards.

Please run application with command:

`simple-scan -d`

and attach the output.

It seems that it is duplication of the upstream issue:

 Hello,

me again.
the first file I sent you had perhaps more activity than you need, or want, it is verbose.  I actually scanned a document, deleted the scan, changed the brightness and contrast controls and did a scan again, at least two times.
The v2 file I am attaching now contains only - run simple-scan  -d, did no scan a document, changed the brightness and contrast controls, closed simple-scan.
Regards,Tony

I have found a workaround that kind of works ... The problem is with the sane library, so it has to be downgraded. I restored /usr/lib/x86_64-linux-gnu/sane/libsane-genesys.so.1.0.27 from my previous Ubuntu 18.04 installation and linked it instead of the current version, and that's all, it works for me in Ubuntu 21.10.

# ls -l /usr/lib/x86_64-linux-gnu/sane/libsane-genesys.so.1
lrwxrwxrwx 1 root root 25 Dez 10 22:52 /usr/lib/x86_64-linux-gnu/sane/libsane-genesys.so.1 -> libsane-genesys.so.1.0.32

# cd /usr/lib/x86_64-linux-gnu/sane
# ln -fs libsane-genesys.so.1.0.27 libsane-genesys.so.1
# ls -l libsane-genesys.so*
lrwxrwxrwx 1 root root 25 Jan 4 16:56 libsane-genesys.so.1 -> libsane-genesys.so.1.0.27

You can try to download the libsane-genesys.so.1.0.27 from here https://ubuntu.pkgs.org/18.04/ubuntu-main-amd64/libsane1_1.0.27-1~experimental3ubuntu2_amd64.deb.html

[Martin Sorgatz (martin-sorgatz)]

I have an old computer with Ubuntu 18.04 LTS where simple scan works fine with an HP Envy printer/scanner.
Now I got a new computer and installed 20.04 LTS where the simple scan shows this issue with the same scanner.

The downgrade of libsane-genesys.so from 1.0.29 to 1.0.27 (I took it from the old computer) does not help on 20.04.
Maybe there are some more bugs in libsane that are already fixed in Ubuntu 21.04?
So I copied the complete /usr/lib/x86_64-linux-gnu/sane/ directory from 18.04. to the 20.04 installation as "sane-old", including the libsane.so.1.0.27 from the directory level above.
I created a shell script that starts simple-scan with LD_LIBRARY_PATH=/usr/lib/x86_64-linux-gnu/sane-old.
But it did not work. I checked the process which libs are loaded (using sudo pldd <pid>).
It loaded mostly the libs from sane-old, but there were still two of the original libs:
.../sane/libsane-ricoh2.so.1
.../sane/libsane-escl.so.1

Then (in /usr/lib/x86_64-linux-gnu) I renamed the "sane" directory to "sane-hidden".
Now (without LD_LIBRARY_PATH) no more original lib from the original subdirectory is used any more (except the top level libsane.so.1 from 1.0.29).
=> Now brightness and contrast can be applied as expected!

Thank you for the information!
I will try this.
Kind Regards

 Hi Martin,
thank you for sharing your exxperience.  Seems you had a more difficult time than Swissz, but found a solution.
I will test on a non prodduction 20.04 and see how it goes.
