Error mdm is no longer supported in linux mint 19 please switch to lightdm

Mint 19.3 нет окна ввода логина

Всем доброго времени, обновил с Mint c 18 до 19 версии. Теперь нет графического окна входа. Если зайти в консоль и выполнить StartX все нормально запускается, если под иксами запустить настройки LightDM и настроить там автологин для пользователя, опять таки все работает рабочий стол запускается автоматом. Вопрос, как вернуть окно выбора пользователя и ввода пароля?

Что в логах? Покажи dmesg, для начала.

Step 2: Switch from MDM to LightDM Display Manager 5. The MDM display manager is not supported in Linux Mint 19, you need to install LightDM. To check your current display manager, run the following command.

/usr/sbin/mdm 6. In case the output shows “/usr/sbin/lightdm”, head over to Step 3. But if the output is “/usr/sbin/mdm” as shown in the above output, you need to switch to LightDM and remove MDM as shown.

$ sudo apt install lightdm lightdm-settings slick-greeter 7. During the package installation process, you will be asked to choose a display manager between MDM and LightDM, choose LightDM, and click Enter.

Choose LightDM Choose LightDM 8. Now remove MDM using the following command.

$ sudo apt remove –purge mdm mint-mdm-themes* 9. Next, reconfigure LightDM using dpkg-reconfigure command and reboot your system.

$ sudo dpkg-reconfigure lightdm $ sudo reboot

Изменить окно входа в систему с MDM на LightDM в Linux Mint 14

Многие пользователи Linux Mint предпочитают более удобное, убунтовское окно входа в систему — LightDM вместо MDM, установленное по умолчанию.

Сделать это не сложно. Откройте терминал (Ctrl+Alt+T), скопируйте и выполните следующую команду:

sudo apt-get install lightdm gnome-settings-daemon indicator-session unity-greeter ubuntu-mono light-themes

Во время установки появится два окна в терминале:

1. Окно с пояснением о дальнейшем выборе менеджера дисплея:

Ответьте утвердительно, нажав Enter.

2. В этом окне нужно выбрать менеджер дисплея, который будет использоваться по умолчанию:

Выберите LightDM, перемещаясь клавишами со стрелками вверх/вниз, а затем клавиша вправо/влево, до покраснения OK и Enter.

Во время входа в систему, по всему дисплею появляются белые точки, которые не всем нравятся. Желающие могут избавится от них, выполнив следующие команды в терминале:

sudo xhost +SI:localuser:lightdm
sudo su lightdm -s /bin/bash
gsettings set com.canonical.unity-greeter draw-grid false

Если вы работаете один/одна за компьютером, то желательно удалить гостевой вход в новом окне. Для этого необходимо подредактировать файл lightdm.conf. Откройте текстовый редактор с файлом, следующей командой:

sudo gedit /etc/lightdm/lightdm.conf

И в конец файла скопируйте и вставьте следующую строку:

Должно получиться как на снимке:

Нажмите Сохранить и закройте редактор.

Вот и всё. Теперь у вас другое окно входа в систему. Чтобы убедиться в этом, завершите сеанс.

How to Upgrade to Linux Mint 19

Linux Mint 19 code named “Tara”, is the latest release of the Mint project. It is a Long Term Support (LTS) release to be supported until 2023. Mint 19 ships in with updated software and enhancements and several new features as explained here.

In this article, we will show how to upgrade from Linux Mint 18, 18.1 or 18.2 to 18.3. Then we will show how to create a system snapshot using timeshift, switch system display manager to LightDM and upgrade to Linux Mint 19 from 18.x.

Requirements:

1. You should have experience with APT package manager and the command line.
2. You should be running Linux Mint 18.3Cinnamon, MATE or XFCE edition, otherwise, first upgrade to Mint 18.3 using the Update Manager, then you can upgrade to Mint 19.
3. Set your terminal to unlimited scrolling; from the terminal windows, go to Edit=>Profile Preferences=>Scrolling. Check the “Scroll on output” or “unlimited” option and click “OK”.

Upgrading to Linux Mint 18.3 From 18.x

As I said, first you need to upgrade to Linux Mint 18.3 from previous Linux Mint 18, 18.1 or 18.2 using upgrade tool as shown.

Go to Menu => Update Manager (if you are shown the update policy screen, select the policy you want and click OK), then click on the Refresh button to check for any new version of mintupdate and mint-upgrade-info.

In case there are updates for any packages, apply them by clicking on Install Updates. Once you have installed all updates, go to Edit => Upgrade to Linux Mint 18.3 Sylvia (this menu item only appears when your system is up to date) as shown in the following screenshot.

Install Updates Upgrade to Linux Mint 18.3

You will see the screen below telling you a new version of Linux Mint is available. Click Next and follows on screen instructions.

Linux Mint New Version

During the installation of upgrades, you will be asked whether to keep or replace configuration files, click on Replace as shown in the following screenshot.

Replace Configuration Files

After the upgrade is finished, reboot your computer.

Upgraded to Linux Mint 18.3

Once you have rebooted, you now have Linux Mint 18.3 running, and you are good to go.

Linux Mint 18.3 Running

Upgrade from Linux 18.3 to Linux Mint 19

1. This is an important and mandatory step, in case the upgrade process doesn’t go well and your system breaks, you can reclaim your system by restoring your latest system snapshot.

Create Linux Mint System Snapshot Using Timeshift

To install timeshift, open a terminal and run the following command.

2. Then go to the system Menu and search for Timeshift, then click on it. Choose the snapshot type and click Next. The timeshift will try to estimate the system size and determine attached storages.

Select Timeshift Snapshot Type

3. From the wizard, select a destination for your snapshots, then click Finish.

Select Linux Mint Snapshot Drive

4. Afterwards, click on the Create button to make a manual snapshot of your operating system.

Creating Linux Mint Snapshot

Once the creation of system snapshot is finished, move to the next step.

Step 2: Switch from MDM to LightDM Display Manager

5. The MDM display manager is not supported in Linux Mint 19, you need to install LightDM. To check your current display manager, run the following command.

6. In case the output shows “/usr/sbin/lightdm”, head over to Step 3. But if the output is “/usr/sbin/mdm” as shown in the above output, you need to switch to LightDM and remove MDM as shown.

7. During the package installation process, you will be asked to choose a display manager between MDM and LightDM, choose LightDM, and click Enter.

Choose LightDM

8. Now remove MDM using the following command.

9. Next, reconfigure LightDM using dpkg-reconfigure command and reboot your system.

Step 3: Upgrading to Linux Mint 19

10. To start, go to Menu => Update Manager (if you are shown the update policy screen, select the policy you want and click OK), then click on “Refresh” to update the APT package manager cache and click Install Updates to apply all updates.

Install Updates

If your system is up to date, proceed to install the upgrade tool by running the following command from a terminal.

11. Next, run the following command to simulate an upgrade and follow the on screen instructions.

This command will:

• temporarily, point your system to the Linux Mint 19 repositories and assesses the impact of an upgrade. Once the simulation is complete, it restores your old repositories.
• let you know which packages will be upgraded, installed, kept back and removed (you can reinstall them after the upgrade).
• also help you point out any packages that are preventing the upgrade, if there are any, remove them to proceed.

Linux Mint Upgrade Summary

12. If you are satisfied with the results from the upgrade simulation process, proceed to download the package upgrades as shown.

Download Mint Upgrade Packages

13. Now its time to apply the upgrades. This is a critical step that you should be careful about, it can’t be reversed, you can only go back by restoring a system snapshot (that is if you properly created one as shown above). Run this command to apply the upgrades.

Upgrading to Linux Mint 19

Sit back and wait for the upgrade to finish. Once it’s done, reboot your system, login and enjoy Linux Mint 19.

If the upgrade process didn’t go well as expected, for one reason or the other, restore your operating system to an earlier state, either from within Linux Mint, or by launching Timeshift from a live Mint session from a live USB or live DVD.

[SOLVED] How to change lightdm to mdm in MINT 19

[SOLVED] How to change lightdm to mdm in MINT 19

Post by Frank-95 » Fri Aug 03, 2018 2:06 pm

I was trying to change the login windows appearance but I really couldn’t find how. From the login window options I could find nothing to install new themes. Then I found out that I was using lightdm, which I had when I used ubuntu years ago and I just hated it. That was one of the reason why I passed to mint, to have mdm.

I’ve been using mint 18.3 with mate since some months, and recently moved to mint 19, and I’ve been completely disoriented when I’ve found out about the login windows manager change. May I ask why? It is almost unadjustable to user preferences and it does not support any themes.
So, is there a clean way to pass to mdm?
With my surprise I’ve also found out that mdm package in synaptic is not what I thought but a completely different thing.

At the moment is this the only way to get mdm? Why it is not included in the default repositories?

About an outdated instruction:

You are aware that the instruction, which you linked to, applied to Ubuntu 12.04, which reached the end of its supported life in April 2017. You should not assume that the same steps still apply on Ubuntu 18.04 / Mint 19, in particular as Mint has switched to LightDM as well.

About configuring LightDM and Slick Greeter:

• Section about «LightDM and Slick Greeter» illustrates how the Slick Greeter login screen can be configured. (Mint 18.2)
• Section about «Login Screen» illustrates improved configuration introduced in Mint 18.3

It will be your decision whether LightDM & Slick Greeter is something which you can get used to on Mint 19 or not.
