Not using any desktop environment. Not using any login manager. Using Debian stretch inside VirtualBox.
Initially during boot the usual grub configuration [1] works for me. The screen resolution get increased from to 1024x768. However, as systemd continues booting, I see "Set console font and keymap". Right before the virtual console (tty1) appears, the resolution is reset to a lower 800x600. The window size decreased. My questions: 1) What changes the tty screen resolution later in the boot process? console-setup.service? 2) How to prevent the screen resolution from being changed or how to change the screen resolution by the program that changes it (console-setup.service?)? fbset does not work at all inside VirtualBox. Error message: ioctl FBIOPUT_VSCREENINFO: Invalid argument Cheers, Patrick [1] GRUB_GFXMODE=1024x768x24 GRUB_GFXPAYLOAD_LINUX=keep or GRUB_GFXPAYLOAD_LINUX=1024x768x24
