I installed Xubuntu Beta 2 18.04 two days back from now. It came with Linux Kernel 188.8.131.52. After updating all the packages it installed 184.108.40.206. Then I rebooted the system.
I installed Nvidia drivers for my Nvidia 1050Ti card and it installed 390.48 drivers in my system. When I rebooted, system never booted. So, I tried to boot into the recovery mode so I could remove Nvidia modules, but when the screen opened with menus, then the keyboard stopped working. It seemed as if system hung up.
So, I restarted using the earlier kernel which didn’t had Nvidia modules and using that I was able to boot into XFCE, and then I removed all the Nvidia modules using “sudo apt-get remove --purge nvidia*”.
After rebooting I was able to boot using the kernel 220.127.116.11 again.
I googled for this, and someone said that “this bug” is fixed in 390.48 but that’s what Ubuntu installed in the first place.
I thought may be the problem was with kernel so, I updated to 4.15.17 kernel using “UKUU” utility but the same problem persisted. Again after installing drivers system didn’t booted.
I can’t move on to kernel 4.16 as my WiFi drivers doesn’t support that kernel version as of yet.
