How to rotate screen AND input (consistently)

[riveravaldez]

Hi,

I'm on Debian 11 in a ThinkPad X220 Tablet (convertible)
and I need to rotate the display (both physically and GUI)
which I do with:

$ xrandr --output LVDS-1 --rotate inverted

But then the input (trackpad/mouse, stylus, touchscreen, etc.)
doesn't rotate accordingly, so it gets unusable...

I've been reading different recommendations online
but can't figure out which would be the best/proper/simpler
approach to achieve this reliably (that hardware input
stays consistent with the GUI in display when rotated).

What should I do? Any hint?

Thanks a lot!

Sad, it's long gone and the contents are virtually lost. It was very
tutorial resource so, I just miss. I have several page printed out on

compilação - Plugin Coppelia

[Leonardo S. S. da Rocha]

Pessoal, boa noite. Preciso de uma orientação. Tem um plugin
disponível no github que estou precisando para grid map usando python
e o simulador CoppeliaSim. Ela está neste link[1] mas se olharem, no
diretório binaries/linux, verão um arquivo (libsimExtGridMap.so) que é
o que eu estou precisando. No entanto, foi complicado errado ou o
autor commitou o arquivo errado, não sei ao certo. Preciso desse
arquivo para rodar o mapeamento feito por um robô no simulador
Coppelia com código Python. A questão é que eu abri uma issue no
repositório e o upstream me informou que eu preciso compilar a
biblioteca e construir o arquivo binário, conforme pode ser visto
aqui[2]. A questão é que não faço ideia de como fazer isso. Alguém tem
algum material que possa me auxiliar nessa tarefa?

That apt-mark is incredibly useful too. Could have saved myself hours
of working through packages working out which ones can be uninstalled.

Just done (after first checking the list of packages it would change)

apt-mark auto $( apt-mark showmanual | grep ^lib )

Then set libreoffice-writer and libreoffice-calc back to manual

And then apt-get autoremove --purge found another four libraries I could
remove. Only 800K of diskspace extra by this point but still, nice to
have when you've only got 4GB to play with.

I shall work through the full list of manually installed packages
flipping those I don't explicitly want to auto - that might find some
more that should be removed too.

Many thanks!

The way to track down a problem like this is to start by adding the
specified "is not going to be installed" packages to the install command
line, with the exact specified versions, and repeat the command.

You'll either get a specific message explaining *why* the "is not going
to be installed" happened, or get more packages listed for "is not going
to be installed". If the latter, rinse and repeat. If the former, the
"why" message will probably help you figure out what needs to be done.

In this case, since you're starting out with a "remove" command rather
than an "install" command, you're going to want to reverse it for
simplicity's sake. That means the second command in the cycle will be
something like (a non-linewrapped version of):

# apt-get install libjbig0- libreoffice-core-nogui=1:7.0.4-4+deb11u1
libreoffice-core=1:7.0.4-4+deb11u1

The trailing '-' on the package name turns the install action into a
remove action for that specific package. You can also use a trailing '+'
to do the reverse, but as in this case you're going to be specifying
more install actions than remove actions, it makes more sense to do it
this way around.


You'll probably also want to make note of your manually-installed
package list before getting started, since this process will wind up
marking the packages you name as manually installed.

The manually-installed package list can be gotten by running

$ apt-mark showmanual

and if you redirect that into a file you'll have a copy for later reference.

An interesting view. I think of ~/.xsession as being the correct,
traditional and well-tested file for a user to customise an X session
begun with startx or xdm. It never fails to work for novice users.

I think of ~/.xsessionrc in terms of the what is in the changelog for
xorg:

  * Add support for $HOME/.xsessionrc. Closes: #411639
This file, if present, will get sourced during the start of your
X session. This allows you to set session-wide environment variables
easily for things like locale information. Patch adapted from one by
Yves-Alexis Perez. Thanks also to Holger Levsen and Osamu Aoki for
advice.

Why can I not uninstall this package?

[Tim Woodall]

I have an old eeepc that I've just upgraded to bullseye. It was getting
very limited on diskspace so I've been going through removing packages
that I no longer require or in some cases, appear to be very old
versions that have been left lying around.

I've now got things under control. However I've hit the following weird
case that I don't understand:

eeepc:/var/lib/dpkg/info# apt-get remove libjbig0
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 libreoffice-base-core : Depends: libreoffice-core-nogui (= 1:7.0.4-4+deb11u1) 
but it is not going to be installed or
  libreoffice-core (= 1:7.0.4-4+deb11u1) but it 
is not going to be installed
 python3-uno : Depends: libreoffice-core-nogui (= 1:7.0.4-4+deb11u1) but it is 
not going to be installed or
libreoffice-core (= 1:7.0.4-4+deb11u1) but it is not 
going to be installed
E: Error, pkgProblemResolver::Resolve generated breaks, this may be
caused by held packages.


This makes no sense to me. apt rdepends libjbig0 lists a handful of
packages none of which I have installed.

libreoffice-core is installed (and the version that is being asked for)

If I remove python3-uno then that problem goes away (until I reinstall
it). I don't want to uninstall libreoffice-base-core.

I haven't yet tried using dpkg to remove the package.

How can I debug what has gone wrong here?

This is a very old debian install that has been updated over the years.
The oldest files I still see in /var/lib/dpkg/info are:

That's not how I'm understanding him. I think he wants something like
https://www.mailscanner.info/ on the gateway, which would pass things
on to and from the MUAs transparently.

If I understand your first line correctly you are connecting directly with
your MUA to connect to the imap server of mail.com.
In this case you have to scan with your MUA.

I am not familiar with mail.com. But do they scan and set any header
based on the scan?
In that case you might to create a imapsieve filter on the imap server
to sort suspicious mail into a spam folder.

There are install CDs with non-free firmware included.

During install, you can choose to add firmware from another
disk or USB stick

Can you describe "does not boot up" more thoroughly? Where does
it stop?

You say the system does not boot up, and yet then you say you're able to
log in.

Perhaps what you mean is that the system does not boot up into a graphical
system, but that you are getting to a login prompt?

If so, after logging in, what happens if you run "startx"?

I have been trying to install Debian on an older computer using the CD1 install.
The installation runs through to completion but the system does not boot up.I 
have tried several times with the same result.
I am able to log in and look at the log file where it informs me that some 
firmwareneeds to be updated. (red warnings)  I have a CD with the firmware but 
how do I install it if the system will not boot?
It seems to me that if the system can install it should be able to run as all 
of the peripheralsneeded are available.  Then I can install the updates.

It looks like the last time it was online with content was
approximately
29 Feb 2020:

something is odd, I see a post on the https://aboutdebian.com/ page 
dated 2021-10-10



I see that as of that date, the site had not been updated for Buster
which by that time had been released nearly half a year earlier.

After that the Web archive shows a blank page and captures from last
month show nothing Debian related.

Intercepting IMAP and SMTP transparently is plausible, but if
you're using SSL/TLS encryption - and you probably are - not easy.

Mail can be scanned:
- by an MTA when it arrives via SMTP
- by an MTA calling a plug-in after the mail has arrived
- by an MTA calling a plug-in while delivering to a mailbox

- by an MUA after it picks up mail

What are your actual restrictions? Tell us more about your
situation.

For instance, if one of your MUAs is a phone running an email
client pointed at mail.com, you will need to convince it to
accept your own SSL certificate authority -- and even then, this
will only work when your gateway is routing network traffic for
the device.

On the other hand, running a mail server that grabs your mail
from mail.com (with your username and password) and then makes
it available to you via IMAP and SMTP is relatively easy, but
does require changing your MUA connections from mail.com to your
mail server.
