Sorry for my bad English, I've a problem during the boot of Ubuntu 18.04 Bionic Beaver.
When I boot the first option of the grub "Ubuntu", a black screen appears and
says: [ 0.004000] 1.55 No iqr handler for vector [ 0.004000] 2.55 No iqr handler for vector [ 0.004000] 3.55 No iqr handler for vector
Or something like that and takes a long time to start the OS, then I can perfectly use it, my laptop is a Lenovo G50-45. I have had problems with the privative drivers, really I'm a newbie in Linux, but this problem makes me annoying.
If you have a link in this forum o another please share me the results or if you know how to resolve it, IDK please.
