I have an Acer V5-472 with intel HD4000 graphics chipset and a built-in 1366*768 display.
I have installed ubuntu 13.10 amd64 in legacy boot mode with an external monitor.
Installation showed no problems, I can boot from HDD and log into my system.
The internal display doesn't work and I have to use an external monitor.
I have tried the following (found in other threads) to no avail:
Setting grub option "acpi_backlight=vendor" or "acpi_osi=Linux" or both.
Installing the intel HD drivers for Linux from their homepage.
Running in circles, screaming and shouting.
The internal display lights up (I can change the brightness with Fn-Left and Fn-Right) but that's all.
When I boot, I get a purple splash screen and from then only the external monitor works.
I read somewhere that this might be a problem with kernel 3.11? Has anybody ubuntu running on an Acer V5-472? Should I change ubuntu version or use 32-bit instead? In general, how can I get the internal display to work?
Edit: The settings->display dialogue shows the internal display correctly with supported resolution of 1366.
