Tails not starting at all

Mac

This section lists known problems with specific hardware.

Tails does not start at all on Mac models that use the Apple M1 chip and on many other Mac models.

Apple does not prioritize collaborating with Free Software projects. Their newest hardware is usually very hard for Free Software developers to get working with Linux, and thus Tails. PC hardware tends to be more open and work better with Linux.

PC

This section lists known problems with specific hardware.

Dell Latitude E5250

Does not start on Tails USB sticks.

Dell Latitude E6430 and E6230

Does not start on USB sticks.

Com versões de BIOS A03 06/03/2012 (e A09, A11, e A12)

Mensagem de erro: Invalid Partition Table!

Pode ser contornado (ao menos com BIOS versões A09, A11, e A12): apenas aperte enter e o sistema vai continuar a inicializar.

HP Compaq CQ60-214DX

Tails 3.3 não inicia.

HP Notebook BCM943142HM

Does not start Tails 4.13.

HP Pavilion 15-ab277ca

Tails 3.3 reinicia durante a inicialização e nunca termina de inicializar com sucesso.

HP ProBook

Com UEFI habilitado, ao escolher um dispositivo de boot, selecione Boot From EFI File e então Filesystem Tails e EFI/BOOT/bootx64.efi.

Aquela alternativa funcionou para, pelo menos, os seguintes modelos do HP ProBook:

• 5330m
• 4330s
• 6560b

System76 Oryx Pro

This machine does not start from a Tails USB stick: the Linux kernel included in at least Tails 3.11 to 3.13.1, inclusive, does not support the hardware USB controller.

Tails not starting entirely

Mac

This section lists known problems with specific hardware.

MacBook Air Retina 2018 and 2019

To start Tails successfully, add the following boot option when starting Tails:

modprobe.blacklist=thunderbolt

Still, the trackpad and keyboard might not work. You can use an external mouse and keyboard.

MacBook Pro 16,1 (A2141)

The computer freezes then automatically restarts. An error message appears saying that the computer was restarted because of a problem.

To prevent this from occurring, add the following boot option when starting Tails:

amdgpu.dpm=0

PC

This section lists known problems with specific hardware.

"Soft lockup" error

On some laptops, Tails starts with the following error:

soft lockup - CPU#N stuck for Ns

To start Tails successfully, try to add the following boot option when starting Tails:

acpi_rev_override=1

Microsoft Surface Laptop 3

The keyboard and mouse do not work on this laptop. If you find a workaround, please let us know.

Microsoft Surface Laptop 4

The keyboard and mouse do not work on this laptop. If you find a workaround, please let us know.

Networking issues

Wi-Fi not working

See troubleshooting Wi-Fi not working.

Problematic Wi-Fi interfaces

Check in this section if there is a workaround to get your Wi-Fi interface work in Tails.

To know the model of your Wi-Fi interface:

1. Open Terminal and execute the following command:

   lspci -v | grep "Network controller"
   

88W8897 [AVASTAR] 802.11ac Wireless

On some computers with a Marvell Avastar 88W8897 Wi-Fi adapter, such as some Microsoft Surface Pro models, Tails fails to connect to Wi-Fi networks.

If you experience this problem, you can try to disable MAC address anonymization that sometimes fixes it.

RTL8723BE PCIe Wireless Network Adapter

On some computers with a RTL8723be Wi-Fi adapter, Tails might fail to discover Wi-Fi networks, provide unreliable Wi-Fi connections, or have poor Wi-Fi performance.

You can try to add the following boot options when starting Tails until you find a combination that works for you. The exact combination of options that works depends on the computer:

• rtl8723be.fwlps=0 rtl8723be.ips=0

• rtl8723be.ant_sel=1

• rtl8723be.ant_sel=2

• rtl8723be.ant_sel=1 rtl8723be.fwlps=0 rtl8723be.ips=0

• rtl8723be.ant_sel=2 rtl8723be.fwlps=0 rtl8723be.ips=0

Broadcom Wi-Fi network interface needing broadcom-sta-dkms

Algumas interfaces Wi-Fi da Broadcom precisam de um driver wl, fornecido pelo pacote Debian broadcom-sta-dkms, para funcionar no Tails.

O driver wl não foi incluído no Tails porque ele é um software proprietário.

Your device requires the wl driver if it is in the list of devices supported by the broadcom-sta-dkms package on the corresponding Debian wiki page. If you find your device in the list of supported devices, then it is impossible to use your Wi-Fi card in Tails.

Lenovo Legion Y530

Wi-Fi adapter does not work.

To fix this issue, add the following boot option when starting Tails:

modprobe.blacklist=ideapad_laptop

RTL8821CE

The Realtek RTL8821CE Wi-Fi adapter is not supported in Linux yet.

This problem is tracked by Debian bug #917941.

Problems connecting to the Tor network

See troubleshooting connecting to Tor.

Other hardware issues

Touchpad configurations

Acer C720 - Cypress APA Touchpad

synclient FingerLow=5;
synclient FingerHigh=5;

Lenovo IdeaPad 3 Touchpad

This touchpad does not work by default. To fix this problem, add the following boot option when starting Tails:

pci=nocrs

Lenovo ThinkPad 11e

Tails might be unstable and stop working regularly on some Lenovo ThinkPad 11e laptops, such as the 2015 model.

To fix this problem, add the following boot option when starting Tails:

intel_idle.max_cstate=1

USB devices are not working on some GIGABYTE motherboards

To workaround this issue, you can try to:

• Use other USB ports. For example, use USB 2 ports instead of USB 3 ports and vice versa.

• Enable these 3 options in the BIOS

  • xHCI handoff
  • EHCI handoff
  • IOMMU controller

• Add the following boot option when starting Tails:

  amd_iommu=on iommu=pt
  

• Disable IOMMU in the BIOS then enable it again.

Some of these workarounds might disable some of the USB ports.

Graphics corruption in Tor Browser and Thunderbird

On some computers, Tor Browser and Thunderbird are displayed incorrectly:

• The application window is initially empty and white.
• The icons and menus only appear when hovered by the mouse.
• The contents of the window is only displayed in stripes when scrolling.

To workaround this issue, add the following boot option when starting Tails:

intel_iommu=off

This problem affects at least the following computers:

• MacBookPro11,5
• other MacBooks with a Radeon R9 graphics adapter

Acer Swift 3

In order to allow Tails to use all available memory, start Tails from the F2 EFI setup firmware entry.

Other issues

Bluetooth devices don't work

Bluetooth não é habilitado no Tails por razões de segurança.

Tails fails to start or behaves weirdly after an automatic upgrade

Sometimes, after an automatic upgrade, your Tails might either:

• Fail to start. Often after the message:

  Loading, please wait...

• Behave weirdly. For example, your keyboard does not work or you cannot connect to a network.

To fix this problem, you can update your Tails manually.

Tails does not erase video memory

Tails doesn't erase the video memory.

When you restart your computer after using Tails, it might briefly display the last screen that was displayed in Tails.

If you shut down your computer instead of restarting it, the video memory will erase itself automatically after some time.
