Oh, I found alternative way that works for GRUB menu resolution and console resolution, too, and no need to create /etc/X11/xorg.conf.
Edit /etc/default/grub accordingly: GRUB_GFXMODE=1280x1024,auto GRUB_GFXPAYLOAD_LINUX=keep,text You may want to or have to use a different resolution than 1280x1024. Thereafter "sudo update-grub" and reboot.
