My Dell laptop has an Intel Graphics HD 3000 driving a 1600×900 LCD. However, For some reason, Ubuntu 13.04 and 14.04 won't let me set the resolution above 1024×768. Can anyone offer any advice? Thanks!

After discovering recently that 14.04 was affected too, I did some more digging and discovered a few things:
nomodeset
is the immediate cause of the problem; I only did this because the laptop in question wouldn't boot otherwise.noacpi
instead solved the video issue, but caused other problems. In particular, only one CPU was detected, when two (or four with HyperThreading) would otherwise be seen.acpi_osi=Linux acpi_backlight=vendor
instead fixed almost all of the problems; the only remaining issue was excessive fan noise.
