Kubuntu 18.04 64 bit gets stuck at Try Kubuntu

Hi,
I managed to solve this. Detailed instructions are over here https://amitsealami.github.io/blog/p...vidia-optimus/ in my personal blog - but in short, I had to install using nomodeset, installed the nvidia drivers using ubuntu-drivers auto install, removed the nomodeset and now can use intel/nvidia graphics.

Excellent work!
Would you mind posting your solution here, so that it will be around in case you drop your web page?

I most certainly will! Here it goes.

Here is what you gotta do.

• When you insert the live usb, and it starts booting - before the Try/Install option shows up, frantically start pressing F6. Yeah, apparently a hidden keyboard action that allows you to switch to the text based options. You might see options such as check for defects, troubleshooting - etc.
• Press F6 again, and a menu shows up. Enable nomodeset, and then go for start
• It will hopefully start using basic graphical capabilities. You should be able to install now.
• After installation is complete, do the usual routine of removing usb, reboot, view the grub
• Check in the grub entry by pressing e and seeing whether the nomodeset is there or not. It should be there since you installed it using nomodeset
• Continue and login. You will notice that the graphics is significantly lagging.
• Open a terminal, update the package list by sudo apt update
• Here comes the magically command. sudo ubuntu-drivers autoinstall.

This command will automatically install the required nvidia drivers.
After this, you should reboot your computer, and you need to edit the grub to remove nomodeset permanently. So,

• open terminal, sudo nano /etc/default/grub
• there should be two lines like: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nouveau.runpm=0" GRUB_CMDLINE_LINUX="nodemodeset"
  make it like:
  GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nouveau.runpm=0" GRUB_CMDLINE_LINUX="" and save it
  
• time to select your graphics driver. There are two options, Nvidia and intel. You should change to intel when you need to save power.
  
• sudo prime-select intel
  
• and you will see that it is remaking the initramfs image, rewriting the grub and other things.
  
• reboot, and you will see that the lagging stopped. if you want to switch to your nvidia graphics, use
  
• sudo prime-select nvidia, reboot. Using this is not recommended as it will significantly increase the battery consumption.

This should be all!
