I just installed Kubuntu (latest version) on dual boot with Windows 8.1 on my ASUS laptop. My boot manager is rEFInd.
I installed Kubuntu without grub (using ubiquity -b) and it installed and worked fine.
Kubuntu prompted me to install the latest drivers for my Nvidia GTX860M (my laptop also has Intel Integrated Graphics). I installed them, rebooted, and now I am stuck on the boot screen, prompting "Wait for Plymouth screen to quit". I cannot access the desktop nor the terminal (using alt+F2).
1 time out of 10, I manage to access the home screen on KDE. When I log in into my session, the screen just freezes (mouse/keyboard not responding).
I googled the issue, but all the solutions rely on using the terminal and editing the grub config file (but I am not using grub).
Would a workaround be possible using my live USB distribution ? Also, how can I make sure Kubuntu installs the proper drivers for my GTX ?
Note that the install is fresh, so I really don't mind erasing it if I have to, even though it would be better not to.
Thank you very much for your help.
