Aparentemente sua máquina tem uma placa de vídeo on-board e outra externa. Entre na BIOS e desabilite a on-board e veja se resolveu.
Colegas,
Estou com uma dúvida que talvez possa ser idiota.
Estou tentando instalar o DisplayLink no Debian e estou com problemas.
Após ler muita coisa na rede, fui tentar ver quais drivers xorg-xserv
eu poderia remover. Fiz o seguinte:
# lspci
00:00.0 Host bridge: Intel Corporation Haswell-ULT DRAM Controller (rev 0b)
00:02.0 VGA compatible controller: Intel Corporation Haswell-ULT Integrated Graphics Controller (rev 0b)
00:03.0 Audio device: Intel Corporation Haswell-ULT HD Audio Controller (rev 0b)
00:14.0 USB controller: Intel Corporation 8 Series USB xHCI HC (rev 04)
00:16.0 Communication controller: Intel Corporation 8 Series HECI #0 (rev 04)
00:1b.0 Audio device: Intel Corporation 8 Series HD Audio Controller (rev 04)
00:1c.0 PCI bridge: Intel Corporation 8 Series PCI Express Root Port 3 (rev e4)
00:1c.3 PCI bridge: Intel Corporation 8 Series PCI Express Root Port 4 (rev e4)
00:1c.4 PCI bridge: Intel Corporation 8 Series PCI Express Root Port 5 (rev e4)
00:1d.0 USB controller: Intel Corporation 8 Series USB EHCI #1 (rev 04)
00:1f.0 ISA bridge: Intel Corporation 8 Series LPC Controller (rev 04)
00:1f.2 SATA controller: Intel Corporation 8 Series SATA Controller 1 [AHCI mode] (rev 04)
00:1f.3 SMBus: Intel Corporation 8 Series SMBus Controller (rev 04)
01:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL810xE PCI Express Fast Ethernet controller (rev 07)
02:00.0 Network controller: Qualcomm Atheros QCA9565 / AR9565 Wireless Network Adapter (rev 01)
03:00.0 Display controller: Advanced Micro Devices, Inc. [AMD/ATI] Topaz XT [Radeon R7 M260/M265 / M340/M360 / M440/M445 / 530/535 / 620/625 Mobile]
Veja que aparecem duas linhas relacionadas a vídeo:
00:02.0 VGA compatible controller: Intel Corporation Haswell-ULT Integrated Graphics Controller (rev 0b)
03:00.0 Display controller: Advanced Micro Devices, Inc. [AMD/ATI] Topaz XT [Radeon R7 M260/M265 / M340/M360 / M440/M445 / 530/535 / 620/625 Mobile]
Quando listo os pacotes xserv-xorg instalados, aparece:
# dpkg -l | grep xserver-xorg
ii xserver-xorg 1:7.7+20 amd64 X.Org X server
ii xserver-xorg-core 2:1.20.7-4 amd64 Xorg X server - core server

ii xserver-xorg-video-vesa 1:2.4.0-2 amd64 X.Org X server -- VESA display driver
ii xserver-xorg-video-vmware 1:13.3.0-2
A minha dúvida é:
Qual é a placa de vídeo e qual o drive que deve permanecer instalado?
aliás, o que eu posso desinstalar para evitar possíveis conflitos?
Além disso, ainda há instalado:
# dpkg -l | grep AMD
ii amd64-microcode 3.20191218.1 amd64 Processor microcode firmware for AMD CPUs
ii firmware-amd-graphics 20190717-2 all Binary firmware for AMD/ATI graphics chips
# dpkg -l | grep intel
ii intel-media-va-driver:amd64 19.4.0r+dfsg1-1 amd64 VAAPI driver for the Intel GEN8+ Graphics family
ii intel-microcode 3.20191115.2 amd64 Processor microcode firmware for Intel CPUs
ii libdrm-intel1:amd64 2.4.100-4 amd64 Userspace interface to intel-specific kernel DRM services -- runtime
Obrigado.
