    Hi,

    is there something i can do to adjust the output on screen when booting efi?
    It seems that legacy booting is limited to a small resolution.

    For example when i boot and deploy via legacy screen contents are filling the screen.
    When i do this via EFI it seems the screen can run higher resolution and therefore the content is much smaller.

    Are there options to adjust this? Some Kernel Args?

    Regards X23

      @x23piracy Try adding nomodeset kernel parameter as a start. Does this help by any chance?

      Web GUI issue? Please check apache error (debian/ubuntu: /var/log/apache2/error.log, centos/fedora/rhel: /var/log/httpd/error_log) and php-fpm log (/var/log/php*-fpm.log)

        Yes there is a kernel parameter for that its the vga parameter.

        vga=792 This should be 1024x768x24
