cldx v. 15 video display doesn't load on Lenovo ThinkPad W520

I installed v. 15 on a separate partition. After rebooting the grub appears but the screen stays black after that.

Any suggestion to correct this will be appreciated.

Thank you for your timely response. I downloaded the Spec sheet but am unsure about what instructions I need to add to the bootloader in order to obtain a working, visible display. Arch and Debian derivatives (as well as Fedora and openSUSE are installed on the same machine but this problem doesn’t occur.

Thanks in advance, once again.
