Error al inciar GDM

Esta sección aplica si ves uno de los siguientes mensajes de error al arrancar Tails:

Error starting GDM with your graphics card: name of your graphics card [id] (rev number). Please take note of this error and visit https://tails.net/gdm for troubleshooting.

1. Identifica el nombre, ID, y numero de revisión (si existe) de tu tarjeta gráfica.

   Por ejemplo, si tu mensaje de error empieza con:

   Error starting GDM with your graphics card: NVIDIA Corporation [10de:0a6c] GT218M [NVS 3100M] (rev a2)

   • El nombre es NVIDIA Corporation GT218M [NVS 3100M].
   • El ID es [10de:0a6c]. El ID es único con respecto al modelo de tu tarjeta gráfica, no es único de tu computadora.
   • El numero de revisión es a2. Tu tarjeta gráfica puede no tener numero de revisión.

2. Mira si tu tarjeta gráfica aparece en la lista. Por ejemplo, puedes buscar por su nombre o ID en esta página.

   • Si tu tarjeta gráfica está listada, mira si hay alguna solución documentada para hacerla funcionar en Tails.

     If the workaround doesn't work, we are sorry that Tails does not work well on this computer. Our best hope is that a future update of Linux drivers will solve the problem.

   • Si tu tarjeta gráfica no está listada, por favor contacta a nuestro equipo de ayuda por email.

     Menciona en tu correo:

     • Cual versión de Tails estás tratando de iniciar.
     • El nombre, ID y número de revisión, si tiene, de tu tarjeta gráfica.

     Puedes enviarnos una foto del mensaje de error como aparece en tu pantalla.

3. Si tu problema se soluciona en una versión futura de Tails, dínoslo para que podamos actualizar esta página.

AMD Radeon HD

Tarjetas gráficas afectadas

Any graphics cards in the Radeon HD family might be affected.

Solución

Si la computadora tiene otra tarjeta gráfica integrada, intente configurar la computadora para usar esa en lugar de la tarjeta gráfica AMD. Por ejemplo, usando esta opción de arranque:

• modprobe.blacklist=amdgpu
• modprobe.blacklist=radeon

AMD Radeon R9

Tarjetas gráficas afectadas

Solución

Adding radeon.dpm=0 to the boot options might fix the issue.

Familia AMD Radeon RX 400

Tarjetas gráficas afectadas

Solución

Adding amdgpu.dc=0 to the boot options might fix the issue.

Other possibly affected graphics cards

Other graphics cards in the Radeon RX 400 series might be affected.

AMD Radeon RX Vega family

Tarjetas gráficas afectadas

Graphics cards in the Radeon RX Vega series, as found in some AMD Ryzen processors, might be affected.

Solución

Try starting Tails using the following boot option:

iommu=soft

Intel

Tarjetas gráficas afectadas

Various Intel graphics card, including but not limited to:

Solución

Try starting Tails using the following boot option:

    i915.force_probe=MODEL

… replacing MODEL with the 4 characters you see after 8086: on the error message.

For example, if you see an error about 8086:4c8a, use this boot option: i915.force_probe=4c8a.

Multiple graphics cards

If the error message lists multiple graphics cards:

• If possible, plug in the monitor into the motherboard's Intel graphics card, as opposed to the external Nvidia or AMD/ATI graphics card.

• Explicitly select one of the two graphics adapters in the BIOS instead of letting the system choose one automatically. If this does not solve the problem, try selecting the other graphics adapter.

• Try starting Tails using the following boot options. You should try only one of these boot options per start attempt.

  • modprobe.blacklist=nouveau
  • nouveau.modeset=0

Other issues

Black screen with switchable graphics computers

Some computers with switchable graphics (such as Optimus) fail to choose a video card and end up on a black screen. This has been reported for MacBook Pro 6,2, MacBook Pro 10,1 Retina, MacBook Pro 15-inch (early 2011) and might affect many others.

Hay varias soluciones posibles para este problema:

• Explicitly select one of the two graphics adapters in the BIOS instead of letting the system choose one automatically. If this does not solve the problem, try selecting the other graphics adapter.

• For the Mac computers, it is possible to use a third-party application, http://gfx.io/, to force integrated graphics only through macOS. Then restart in that special mode that works with Tails.

Virtual machines with virt-manager, libvirt and QEMU

See the dedicated troubleshooting documentation about graphics issues in Tails running inside a virtual machine with virt-manager.

Virtual machines with VMware

To improve support of Tails running inside a virtual machine with VMware, install the open-vm-tools-desktop software package as Additional Software in Tails.

Probing EDD error

Use these instructions if Tails failed to start and displayed the following error:

    Probing EDD (edd=off to disable)...

1. Follow our guide for editing boot options.

2. For the guide's "Modify the boot options as needed" step, type edd=off to add this option to the command line.

Display artifact when starting Tails on Intel display

If you see screen tearing and color artifact shift through display with an Intel graphics card, try this:

1. Right-click on the desktop
2. Click Display Settings
3. Change the refresh rate to a different value.
   For example, setting the refresh rate to 48 HZ fixed the problem on Tails 5.9 with this hardware: Gemini Lake N4100 (Intel Graphics 600).
