Kubuntu 18.04 64 bit gets stuck at Try Kubuntu

[lordamit]

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!

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?

If a reburn doesn't fix it then perhaps, for your hardware, there is a bug in the ISO.

Yesterday I read an article about how much faster "Clean Linux" (a distro) was over Ubuntu, and several other distros. I downloaded the 5.4Gb Live img and checksummed it. I used THEIR dd command to burn it to an 8GB USB stick. Took 1,042 seconds.
When I rebooted and selected it I saw the USB light flicker, but then my system booted. So, I tried a power down, 30 second pause to let capacitors drain, and then a power up. The lights flickered again, but my Neon started up. Bad burn?

Then I tried Etcher-electron to burn it and verify the burn.
Same problem. "mmmm ..." I thought, "maybe my USB stick is too small?".

I burned the img onto a 64GB USB stick using Etcher, which verified the burn, as it usually does.
From a cold boot I saw the USB stick light flicker and my Neon booted again.

At that point I'd wasted an hour. With my six year old MBR boot system it looks like Clean Linux isn't going to boot.

In your situation you've successfully installed it, but at the login screen it locks up when you either enter your credentials or try to use the keyboard to open a TTY. This suggests a video chip driver problem. Use the recovery option to log in as root with remounting your file system to change it from ro to rw. Log into your user account and see if "startx" or "startkde" gives you a working desktop.

If it doesn't then you can use lshw or lsmod to see what video driver is being used, and modifno for that driver to see what settable "parm" it has.

Yes, never removed the ISO. But rechecked anyway.

[GreyGeek]

We have to start at the beginning. Did you checksum the ISO?

[lordamit]

Hi,
I tried installing Kubuntu, and it installed fine in a new SDD.
However, now after I enter credentials - it freezes in a black screen with a logo.
I tried to switch to tty - didn't work. I tried switching to tty without entering password - didn't work and froze.

I actually already have both Windows and Linux mint 18.3 installed in dual mode. Additionally, I can not spare any drives for a seperate setup. Moreover, It seems like currently support for Primus laptops in 18.04 LTS series is not well enough based on this https://devtalk.nvidia.com/default/t...stributions-/2
I can wait fo r the next point release (18.04.01 or 18.04.02) to see how it goes.

That was my experience with Kubuntu 18.04. During the after the initial install I was notified of proprietary device drivers and the NVidia 390 was offered as the recommended option. I accepted and the installation proceeded. When it was done the Nvidia config GUI was incomplete. After researching the problem I noticed that the installation didn't include the Bumblebee and Prime apps, I added them, 34 packages in all, and rebooted. That fixed the problem.

I downloaded the 64bit Version.
Verified the sha-256 checksum.
Burned it on DVD and installed it on USB with Universal-USB-Installer-1.9.6.8.
DVD and USB startup on "try kubuntu" with the same result.

Windows 10 64bit is currently installed. Before Windows 10 I had installed Suse 42.1 64bit on that system.

Edit: Same problem with Xubuntu 18.04 64bit.
Edit2: No problem with LMDE 2 mate 64bit.

Unfortunately there's nothing helpful in the pic, Did you use the correct architecture (32 vs 64 bit) and verify your burn was good?

[torb1]

Just my short feedback for kubuntu 18.04.
I wanted to try it on an old Intel Dual Core PC. Got stuck (see picture enclosed)



Windows 10 is working. Had no problems with Suse 42.1.

Hello All,

I am using Acer Nitro 5 Laptop (https://ryanscomputers.com/acer-nitr...-product-view2), which has intel graphics and Nvidia graphics. I have downloaded Kubuntu 18.04 LTS 64 bit using Torrent, set up a USB stick using the ISO and rebooted computer to go to the installation screen.
Checking disk for defects yielded no errors.
After I was presented the options

1. Try Kubuntu
2. Install Kubuntu

If I select Try Kubuntu, it immadiately freezes. Nothing works. Except the hard power button of course.

If I select Install Kubuntu, it can proceed to the keyboard layout, conencitivity and other options. Understandably, I didn't complete this step. I did not want to take the risk of installing it considering the factor that it might freeze after installation and booting!

If this is relevant, I am using Linux Mint 18.3 Cinnamon 64 bit currently, and it works out of the box for my laptop. Installing the necessary drivers from device manager works well and does not require me to setup anything or modify any files.

Please let me know if there is any other information I can provide to help you understand why it is freezing. Thanks, and looking forward to installing Kubuntu 18.04 LTS ASAP.

had the same thing happen to me about 8 months ago on this laptop. I decided to try 3 different distros including a Win 7 disc all with the same result. Replaced the (failing) HDD, problem solved.

You could always try and install it anyway to a partition without wiping Mint or installing grub over your current grub. The problem might not return from an updated installation.

Well, now you know your USB ISO is Ok.
IF I read the specs of that Nitro5 correctly it comes with Free Dos installed, not Windows, which you overwrote with Mint. But, you want to try KDE.
IF you don't want to overwrite your Mint installation an option is to use parted and peel back a 100GB or so to make a partition on which you can install Bionic in dual boot mode. If it works out you can leave it that way. If you decide to dump Kubuntu you can use parted to give that partition back to Mint. If you decide to dump Mint because you've proven that Kubuntu works well on your rig, you can reinstall it to the entire HD. IF you do that then I suggest using the manual mode, create a 10Gb swap partition, and give the rest to / with Btrfs as the root file system.
