Estoy ejecutando un Lenovo T14 gen 1 AMD con Ubuntu 20.04 y kernel 5.8.0-rc7, el controlador AMD 20.20 está instalado. Mi objetivo es ejecutar 2 pantallas con la base Lenovo Thunderbolt3 (la actualicé ayer con una computadora con ventana), que está conectada al puerto tb3 de la computadora portátil. Las pantallas que estoy usando son Dell de 27" y Dell de 34", ambas conectadas a través de DP.
En este momento tengo que tener ambas pantallas conectadas para que la de 34" funcione en resolución completa; de lo contrario, solo funcionará en 2560x1440. Al intentar activar la pantalla de 27", aparece el siguiente error en syslog:
Aug 14 10:16:30 Vmax /usr/lib/gdm3/gdm-x-session[2308]: (EE) AMDGPU(0): failed to set mode: No space left on device

¿Cómo puedo deshacerme de los errores y hacer que esta configuración funcione?
Respuesta1
La versión AMD no tiene Thunderbolt, por lo que no funcionará con la base TB3.

Misma computadora portátil, mismo problema, en Manjaro Linux
Linux thinkpad-t14 5.7.19-2-MANJARO #1 SMP PREEMPT Fri Aug 28 20:22:12 UTC 2020 x86_64 GNU/Linux
Lo resolví usando un cable HDMI en lugar de un convertidor USB-C a HDMI para conectar mi monitor externo. Probablemente compraré un divisor HDMI y espero que mis dos monitores externos funcionen desde la salida HDMI de la computadora portátil.
Espero que ayude

Estoy usando una base enchufable Thunderbolt 3/USB-C junto con un adaptador Sabrent USB-C dual HDMI. Tengo teclado, mouse, etc... conectados al dock, junto con un solo monitor. Cuando se usa USB-C en lugar de Thunderbolt en la base, impulsará dos monitores de 1080p o un solo monitor 4K; en TB3, impulsará ambos. Lo extraño que me encuentro y que no puedo solucionar es que el monitor no se activa con el teclado, mouse, etc... Tengo que desconectar y enchufar la conexión USB-C. Opté por el conector USB-C magnético para poder hacerlo fácilmente. El dongle USB-C Sabrent funciona desde el modo de suspensión. Conecté ambos monitores y pude hacer que AMD FreeSync (que no estoy seguro de que sea exactamente) apareciera en mi pantalla, ya que los monitores lo admiten.
