Sane Scanner Resolution Configuration
by Stephen Morris
Hi,
Having installed imagescan from Epson, and installed sane and
xsane, and edited the imagescan config file to specify the network
settings of my printer all-in-one, I now have xsane finding my scanner,
but this has highlighted a problem.
Having run xsane it has created Epson:ET-3700.drc in path
~/.sane/xsane, which contains all the options used by xsane for
scanning. Two of the options are for the horizontal and vertical scan
resolution, which by default are set to 75. These options are reflected
in the xsane gui, but they are disabled so I can't alter them from the
gui, I have to edit the config file and specify the resolution I want in
there.
Where can I find documentation on the format of that xsane config
file, that would tell me how I get the list of resolutions the scanner
supports into that config file so that they are selectable by a dropdown
in the xsane gui?
regards,
Steve

whereis 'Users Settings Tool'
by Geoffrey Leach
The doc for Fedora 32 makes reference to a 'Users Settings Tool'
accessible (secretly) from the Settings tool. It does not appear to be
available. Any idea why? Or where there might be a similar GUI?

What is Portal and pipewire and Why Did They Start?
by Garry T. Williams
A few weeks ago I installed F32-KDE fresh on a workstation (a disk
drive failed). All of a sudden last night Portal service was started
(whatever that is). I did nothing that I know of to trigger this.
Furthermore, since updating after installing this system, that service
has never been started until now.
Directly after the Portal service started, I see error messages coming
from pipewire (whatever that is).
Can anyone tell me what this is all about and why it happens now?
(I'm especially concerned about why it started.)

reboot after upgrade? and best practice
by Anil Felipe Duggirala
hello everyone,
I would like to ask what is the best practice for upgrading (updating all packages, ie. "dnf upgrade") in my Fedora 32 Workstation. The Gnome Software graphical application provides a way for me to do this, but it can also be achieved in the command line. Do these two methods achieve exactly the same results? I would also like to plainly ask if in any occasion it is necessary or advisable to perform a system reboot after doing an "dnf upgrade". I have noticed that when the upgrade is performed with Gnome Software, a reboot is always performed after the upgrade.
thank you,

NFS opens simply by selecting with one click, I think SMB should do the same as it does in the other, ws2, Fedora-31, computer with Thunar?

But a new observation, In Thunar I selected File System and navigated through mnt to smb and dragged it over to the left panel where it happily resides next to NFS, both under Places in the right panel, below them is the smb I was talking about that does not open anything, the one above does open and provide the list of files.

Here is the "problem".
When you have the share mounted on /mnt/smb there should be *no* smb entry in the Left-Panel.
That is because Thunar is only "scanning" /media for local mounts. When a mount occurs under
/media Thunar will place an entry in the Left-Panel under Devices. It will *not* do that for mounts under /mnt.
If the share under /media is unmounted Thunar should remove the entry from the Left-Panel.
Why it is still there on you Thunar, I do not know. However, it is a useless entry. No amount of clicking on
it will be effective.
When I do a mount of the share under /mnt I do *not* have an smb entry on the Left-Panel.
I have shown that with images I've post online.
There should never be a need to drag and drop entries to the Left-Panel. As a matter of fact,
I think that will cause more confusion than ever since I think the action is actually creating a
short cut of some sort.
I really don't know how Thunar is currently showing things and I think the GUI has been confused
by the actions taken. I don't know how Thunar keeps track of where things may be.
I don't know how to "reset" Thunar. It *may* be helpful to post a screenshot of your Thunar
online.
I would consider either deleting the user "bobg" on ws1 and then recreating the user. Making sure
the uid and gid of the new user are 1000. Or I would change the name and uid/gid of bobg
and then make a new user bobg.
To me part of the problem/confusion comes from naming the share mount points and a system the
same as the protocol.

You can right-click on that SMB in Places and then select "Remove Shortcut".
