I have tried to install SLED 12 SP 1 on a Dell Inspiron 3531 but without success because, even if the installer was displayed correctly, the desktop never appeared at first boot.

I tried to google it without finding a how-to. I will try again next week so perhaps someone here could have any tip to make it a success ?

I currently have Linux Mint 18 Mate running on the laptop but for professional reasons I would like to switch to SLED.

Thanks for any advice
