After I upgraded by old Ivy Bridge machine Ubuntu 24.04, the machine won't boot into GNOME. However if I started from recovery mode and then resumed the boot, I can get into GNOME fine. After a bit of research, it seems for the i915 to work, the extra kernel parameter nomodeset needs to be added to the GRUB_CMDLINE_LINUX_DEFAULT in /etc/default/grub file. Indeed after, nomodeset is added, the machine boots into GNOME as it should be.
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset usbcore.autosuspend=-1"
Just a reminder, for the settings to become effective, don't forget to run updatre-grub2 after the changes!
Update 2024-07-28:
I finally managed to get DVI to work. The solution is a rather odd one. Instead of using UEFI, you simple switch back to the legacy BIOS. Voila, DVI is back and working as it should.
