Hello to everyone.
I've installed a qemu / kvm debian buster / armhf VM on top of my jetson nano / arm64. This is the procedure that I have used :
stage 1 : I've created this script for the installation :
installer-buster.sh :
qemu-system-aarch64 -M virt -m 2048 -smp 2 -cpu host,aarch64=off -enable-kvm \
-kernel /home/zi/Desktop/Work/I9/Arm32/debian10-buster/installer/vmlinuz \
-initrd /home/zi/Desktop/Work/I9/Arm32/debian10-buster/installer/initrd.gz \
-drive if=none,file=hda-buster.qcow2,format=qcow2,id=hd \
-device virtio-blk-device,drive=hd \
-netdev user,id=mynet \
-device virtio-net-device,netdev=mynet \
-nographic -no-reboot
stage 2 : I've created this script for the booting :
booting-buster.sh
qemu-system-aarch64 -M virt -m 2048 -smp 2 -cpu host,aarch64=off -enable-kvm \
-kernel /home/zi/Desktop/Work/I9/Arm32/debian10-buster/vmlinuz-4.19.0-14-armmp-lpae \
-initrd /home/zi/Desktop/Work/I9/Arm32/debian10-buster/initrd.img-4.19.0-14-armmp-lpae \
-append 'root=/dev/vda2' \
-device usb-ehci -device usb-kbd -device usb-mouse -usb -serial stdio \
-device virtio-gpu-pci,virgl=on,xres=1920,yres=1080 -display sdl,gl=on \
-drive if=none,file=/home/zi/Desktop/Work/I9/Arm32/hda-buster.qcow2,format=qcow2,id=hd \
-device virtio-blk-device,drive=hd -netdev user,id=mynet \
-device virtio-net-device,netdev=mynet \
-bios edk2-arm-code.fd \
-no-reboot
What's the problem ? Problem is that when the login screen is shown,my mouse and my keyboard don't work. Investigating I think that I've found the reason. This is the content of :
/etc/gdm3/daemon.conf
# GDM configuration storage
# See /usr/share/gdm/gdm.schemas for a list of available options.
[daemon]
# Uncomment the line below to force the login screen to use Xorg
#WaylandEnable=false
# Enabling automatic login
# AutomaticLoginEnable = true
# AutomaticLogin = user1
# Enabling timed login
# TimedLoginEnable = true
# TimedLogin = user1
# TimedLoginDelay = 10
As you can see it tells that Wayland should be enabled. I suspect that this is the reason why my mouse and keyboard don't work with a qemu and kvm Buster VM. Anyway,I've tried to do how it suggests to do,uncommenting the line below to force the login screen to use Xorg :
WaylandEnable=false
but it didn't work anyway. My mouse and keyboard still don't work. This time I can see the error message :
buster login: broken atomic modeset userspace detected, disabling atomic
so. How can I fix this bug ?
