I was working with Comsol and the simulations were big so Ubuntu (18 LTS) was stopping in the middle of the simulation with the cursor locked and I had to turn the laptop off with the power button. This happened several times until finally the laptop did not boot instead it shows the grub menu. From there if I choose to boot normally there comes a black screen and nothing happens even in
If I choose the recovery mode it works a little bit until it stops again at a screen with some lines of code. I cant put the picture of the screen here without reputation but the last line reads something like:
[ 1.971959 ] ehci-pci 0000:00:04.1: irq 17, io mem 0xd3389200
I also tried booting from USB which goes to the black screen even with the
nomodeset. Similarly if I try to install a new one it goes to the black screen even in
My laptop is a MacBook 2008 model which is why the comsol simulations were so heavy for it.
