Bom dia pessoal.
Estou com um problema para usar duas telas com o Ubuntu 22.04.3 LTS.
Até ontem tudo funcionava normalmente, conforme as telas a seguir:
Do nada, ao ligar o notebook (um lenovo thinkpad e14) o monitor samsung (um modelo antigo - syncmaster 932bwe - com vga mesmo) não apresentava a segunda tela, apesar de reconhecê-la.
Realizei todos os testes de hardware: o monitor está funcionando (liguei em outro pc), o cabo vga também (liguei em outro pc), o adaptador hdmi → vga também (liguei em outro note), a saída hdmi do note também (liguei na tv).
Não fiz nenhuma atualização ou alteração de sistema ou hardware. Testei alterações da taxa de atualização e outras resoluções bem como testei com Xorg também e nada.
O drive de vídeo é o VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Lucienne (rev c2).
O kernel é o Linux 6.8.0-90-generic #91~22.04.1-Ubuntu SMP PREEMPT_DYNAMIC Thu Nov 20 15:20:45 UTC 2 x86_64 x86_64 x86_64 GNU/Linux:45 UTC 2 x86_64 x86_64 x86_64 GNU/Linux
Alguém teria alguma ideia do que poderia estar acontecendo?
Consigo apenas essas informações no syslog:
