Tenemos una estación de trabajo en nuestro grupo que tiene una placa base KNPA-U16 y una GPU AMD RX560 que funciona la mayor parte del tiempo. El Sistema Operativo es Kubuntu 20.04 y la versión del kernel 5.8.0-59.
Ahora el problema aparece cuando no utilizamos la estación de trabajo durante un tiempo y luego intentamos acceder a ella desde delante. El comportamiento es el siguiente: la pantalla aparece durante un breve período de tiempo (varía entre ~0 y 10 segundos) y luego se vuelve negra. Como dije, el tiempo varía, una vez incluso pude iniciar sesión antes de que la pantalla se oscureciera. Ya no hay posibilidad de despertarlo después de ese evento. Sin embargo, se puede acceder a él a través de ssh.
El registro del kernel muestra lo siguiente:

Tuvimos el problema desde hace mucho tiempo (~ 1 año, visible en el registro de eventos de SMBIOS) e intentamos algunas cosas:
- Sacar la tarjeta gráfica de la ranura PCIe y volver a enchufarla
- Instalación de un nuevo kernel
- Instalación de los controladores propietarios amdgpu
- Desactivando todas las configuraciones de suspensión en Kubuntu pudimos encontrar
- Usando pcie_aspm=apagado
- Usando una pantalla diferente (DVI/Display port)
- Cambiar algunas configuraciones del BIOS relacionadas con PCIe
Sin embargo, nada de lo que hacemos parece cambiar nada. Lo que hace que sea tan difícil solucionar este problema es que sólo aparece si la PC no se utiliza durante algún tiempo. Así que es realmente complicado probar cualquier cosa.
¿Alguien tiene una idea de cuál podría ser el error o dónde podríamos empezar a buscar según el registro?
Actualización, probamos la tarjeta gráfica en una PC diferente con Windows y funcionó bien. Luego instalamos Win 10 en la misma PC y también funciona sin problemas. Entonces parece ser la combinación GPU + placa base + KDE neon. Linux parece permitir algún tipo de estado de ahorro de energía que no va bien con la placa base. Sin embargo, buscamos mucho y no encontramos ninguna opción de hibernación que no hayamos desactivado.
