Using GRUB_GFXMODE=640x480 and creating the /etc/modprobe.d/nf file, but with no results - it keeps starting at 800圆00Ĭan anyone help on this? I am currently using Debian 9, can move to another version in case of incompatibilities.ĮDIT: as requested, here is the output of #cat /proc/cmdline:īOOT_IMAGE=/boot/vmlinuz-4.9. I installed Ubuntu 14.04 LTS amd64 desktop on VirtualBox 4.3.26 which is running on OSX10.10 (amd64) and the only option for screen resolution is 640x480. Modify it to required resolution: GRUB_GFXMODE=1024x768Īdd the following: GRUB_GFXPAYLOAD_LINUX=keepĮdit "/etc/modprobe.d/nf" and add vboxvideo Reboot I followed the suggestions found at edit /etc/default/grub I used the systemctl set-default multi-user.target command to make the VM start on framebuffer, but it seems it cannot go below 800圆00 resolution.Īll tutorials and guide I can find are related to starting the guest VM at high resolution modes, while I cannot find anything tackling with my issue. In order to port an embedded project from an ARM target to Linux/x86, I have to create a Debian VM (I'm using Virtualbox right now) which starts in framebuffer mode with 640x480 resolution.
