Deteksi Grafik Ubuntu
Intel i915 driver module, which should recognise your graphics chipset, should be loaded in kernel by default. Probably that's why it's not listed in Additional driver.
What is the output of the command lsmod | grep i915? If it's returning i915 that means the module is already loaded and working.
If not then open /boot/grub/grub.cfg and check if the kernel line (the line which is started with linux /boot/vmlinuz..) has the parameter i915.modeset=1. If not or if the line has parameter nomodeset then open /etc/default/grub and edit the following line as
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i915.modeset=1" then reboot. See if that works.
