Setting display size of linux guest on VirtualBox
Recently I have initiated a jeos image with VirtualBox , after booting I had a small sized shell window , which wasn’t really friendly to use .
Basic installation of jeos dosn’t have any X related stuff installed so I have found that there is an option to set vga mode ( resolution and color depth ) while setting vga=XXX on kernel setup of grub boot loader .
In /boot/grub/menu.lst line that begins with kernel and add vga=### to it . This value needs to be in decimal.
For example : 1024×768 16bit mode code is 0×317 which is 791 in decimal notation , so we should add vga=791 to kernel setup .
Colours 640x400 640x480 800x600 1024x768 1152x864 1280x1024 1600x1200 -------+-------------------------------------------------------------- 4 bits | ? ? 0x302 ? ? ? ? 8 bits | 0x300 0x301 0x303 0x305 0x161 0x307 0x31C 15 bits | ? 0x310 0x313 0x316 0x162 0x319 0x31D 16 bits | ? 0x311 0x314 0x317 0x163 0x31A 0x31E decimal | d785 d788 d791 24 bits | ? 0x312 0x315 0x318 ? 0x31B 0x31F decimal | d786 d789 d792 32 bits | ? ? ? ? 0x164 ?
