Ubuntu: Ubuntu 12.04 on Intel NUC5CPYH



Question:

I have installed Ubuntu 12.04 on intel NYC5CPYH using usb. Display was good when booted from live disk, but after installation it is giving an error of low graphics mode and after this it freezes. There is no way even to go to console. Is there any way I can get graphics settings when booted via live usb stick and use it to solve the low graphics issue. The monitor in this case is a 48" LED tv.


Solution:1

I have the same NUC. You will need a reasonably recent kernel that supports Intel HD Graphics (Braswell) which is inbuilt in your NUC's CPU (Intel Celeron N3050) - I think support was added in 4.2, but it could be also 4.1. These kernels are not available in standard repositories for Ubuntu 12.04, so you will have to head over to http://kernel.ubuntu.com/~kernel-ppa/mainline/ and select one of the 4.x kernels, download the .deb packages relevant to your system (in your case, amd64 of the "generic" variety, low-latency is not normally recommended) and install them with dpkg -i. For example:

wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.5-wily/linux-headers-4.5.0-040500-generic_4.5.0-040500.201603140130_amd64.deb  wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.5-wily/linux-image-4.5.0-040500-generic_4.5.0-040500.201603140130_amd64.deb  sudo dpkg -i linux-headers-4.5.0-040500-generic_4.5.0-040500.201603140130_amd64.deb  sudo dpkg -i linux-image-4.5.0-040500-generic_4.5.0-040500.201603140130_amd64.deb  

After installing the packages, run sudo update-grub and reboot. The graphics should work fine now.
