Hi Gordan,
If you want to retain the output on serial console, please add kernel command "console=ttyS0,115200" at the grub config. If you want to see the kernel boot at both serial and vga, add "console=tty0" (for vga) along side with "console=ttyS0,115200". The output from VGA will come after kernel configure the video card.
nomodeset does not help to retain serial output, it just means that you want to use X drivers, instead of kernel modesetting.
Best regards,
Chuong.

When the kernel boots and the fb driver initializes and the initramfs starts, the output disappers from the serial console. This seems to correspond to the display output switching to a different mode. It is present during u-boot, Tianocore and grub, however. Is there a way to tell the kernel to not change the mode so that full control via the serial line can be retained? I tried "nomodeset" which I think should do this by disabling modesetting, but it has been ineffective. Is there a way to achieve this? _______________________________________________ Arm-dev mailing list Arm-dev@centos.org https://lists.centos.org/mailman/listinfo/arm-dev
