It’s Ctrl+Alt+L, not Ctrl+Shift+L, in both Mint and Ubuntu.

If that still doesn’t work you should find a keyboard shortcuts utility in the menu where you can check/define any necessary shortcuts.

Oh, I figured it out. It’s a bug, I think.

Let me explain. I use the Dvorak keyboard layout in Linux. But for the keyboard shortcut to work, I have to press the Qwerty equivalent of the L key (which corresponds to the key which has the L key printed on my keyboard.) I was pressing the key that has the «P» letter printed, because the P key is L key in Dvorak. I remember that Ubuntu also has the same thing, so I went into the Keyboard Shortcut utility and changed the shortcut to Ctrl+Alt+P instead.

That’s a workaround. Wish the developers would fix this bug.

I checked Mint 19 Xfce 64-bit in a VirtualBox VM; indeed Ctrl-Alt-Del is the standard screen-lock shortcut (note, in a VirtualBox VM Ctrl-Alt == «Host Key», by default Right-Ctrl).

But. if you check Settings -> Keyboard -> «Application shortcuts» you find it invokes xflock4 which is supposedly the «command line» you spoke of. If indeed that does nothing neither then will Ctrl-Alt-Del / Host-Del. Xflock4 is a simple shell script: less $(which xflock4) . xscreensaver-command nor gnome-screensaver-command is installed by default on 19 Xfce but light-locker-command is. Did you happen to uninstall light-locker? Does a direct light-locker-command —lock report anything usable?

After you install xfconf, does xfconf-query -c xfce4-session -p /general/LockCommand report anything other than ‘Property «/general/LockCommand» does not exist on channel «xfce4-session»‘? It should not by default so if you have anything set there try and reset it with xfconf-query -c xfce4-session -p /general/LockCommand -r .

Hope this helps: need to be off to bed for now.

Afaict, the permissions to execute the «xflock4» shell script are set to «Root», exclusively. However, even when trying to execute it with sudo, xflock4 still does nothing — your very own experience; obviously, there’s a bug in there somewhere . This finding applies to both LM19-xfce & LM18.3-xfce. Even activating the «Lock Screen» option in Xfce’s whisker-menu (Whisker-button > right click > Properties > Commands Tab > Lock Screen Option), configured to execute «xflock4», does nothing. However, i’ve successfully tried from a terminal screen xfce’s native «xfce4-session-logout —logout» command. It works just fine . saves my session, presents the login screen, and upon my login restores the state of my open apps. Can you try.

and see if it works on your system?

PS: on my LM19-xfce test system, i edited whisker’s «Lock Screen» command using the foregoing (new) syntax, and it works just as well as when run from the terminal. As a temp workaround, its easy to add a button to your panel Iif that’s what you want). Good luck!

Another place to look would be:

Power Management > Advanced Settings > uncheck Lock on Resume

(KDE version at least)

Screen Lock activation time

Screen Lock activation time

Post by kanichiro » Thu Nov 07, 2013 12:55 pm

Hello,
I installed Linux Mint last week after using Ubuntu and Ubuntu Studio for the past 6 plus years. So far I really like Linux Mint. However, I have two issues that I cannot seem to fix.
* The Screen Lock activates in about 7 or 8 minutes.
* I am not able to access either my iPad, or my iPhone from Linux Mint (I was able to access both from Ubuntu & Ubuntu Studio).
I run a duel-boot system (Windows 7 Pro/Linux Mint).

For this post, I’ll stick to the lock Screen time.
* In Power Settings I have «AC Power» set to a 30-minute lock.
* In «Battery» the timeout is set to 10-minutes.
* The Screen Saver is set for 45-minutes.

As I stated, my screen locks around 7 to 8 minutes, even with the above settings.

Any all help would be gratefully appreciated!

I’m running Linux Mint 15 (Olivia) with the MATE desktop.

I unchecked, and then rechecked the selections for «Activate the Screen Saver when computer is idle,» and Lock Screen when screensaver is active.» For whatever reason, the timeout now works properly. A glitch I suppose.

Дети нашли уязвимость в экране блокировки Linux Mint, случайно нажимая клавиши

На прошлой неделе разработчики проекта Linux Mint исправили довольно опасную уязвимость, которая позволяла обойти скринсейвер и без ввода пароля выйти на рабочий стол.

Согласно баг-репорту на GitHub, этот неприятный баг был обнаружен двумя детьми, играющими на компьютере своего отца.

«Несколько недель назад дети хотели хакнуть мой компьютер, поэтому нажимали на все клавиши, пока я стоял позади и смотрел, как они играют», — написал пользователь под ником robo2bobo.

Согласно баг-репорту, двое детей нажимали случайные клавиши как на физической, так и на экранной клавиатурах. Это в конечном итоге привело к сбою заставки Linux Mint, что позволило им получить доступ к рабочему столу.

«Я думал, что это уникальный инцидент, но им удалось сделать это во второй раз», — добавил пользователь.

По словам ведущего разработчика Linux Mint Клемента Лефевра, проблему в конечном итоге отследили до libcaribou, компонента экранной клавиатуры (OSK), которая поставляется с Cinnamon, оболочкой для среды рабочего стола в Linux Mint.

Конкретно, ошибка возникает при нажатии клавиши ‘ē’ на экранной клавиатуре.

В большинстве случаев баг приводит к сбою рабочего стола Cinnamon, но если экранная клавиатура открывается из заставки, то вместо этого происходит сбой заставки, позволяя пользователю получить доступ к основному рабочему столу.

Лефевр сказал, что баг ввели в основную ветку в октябре прошлого года с патчем для другой уязвимости CVE-2020-25712. С тех пор были уязвимы все дистрибутивы Linux Mint, использующие Cinnamon версии 4.2 и более поздних версий.

Патч выпущен 13 января 2021 года. Сейчас разработчики Linux Mint планируют добавить настройку, которая даст возможность пользователю отключать экранную клавиатуру, что облегчит устранение будущих ошибок в этом компоненте.
