Kubuntu 18.04 hangs in logoscreen
 

Hi,

I have a problem with an Asus all-in-one with touchscreen ASUS A41.

During boot it stops with the kubuntu logo.

I tried to get to the commandprompt but virtual terminals are disabled so no Shift-F2.
Even Grub is configured so that the machine starts immidiately in Kubuntu.

If I start from CD cann I change the grub-settings so I can get a command-prompt?

The problem seems a known one and cause by NVidia and a particular kernel-version, so I hope that apt update and apt upgrade will solve it.

The only information I could get out of the system is the following screenshot.

Please give me some hints on how I get to a command-prompt.

Thanks in advance,
Jan

Does Ctrl-Alt-F1 not give you a virtual terminal?

No it does not, I guess I disabled it because the user is likely to experiment and blow his POS this way.

When I use Ctrl-Alt-F2, or F3 etc I only get a blinking cursor.
No reaktion on ctrl-C, ctrl-Z, ctrl-Y, ctrl-Backspace.

Have you tried holding down the Shift key (try both left and right separately), the Esc key, or the Spacebar key at boot-up to try and force the Grub menu to show?

Hi,

I tried Ctrl-Alt-F2 on my notebook and it gives me a nice login to the commandprompt,
what I do not get on the system with the problem.

I have not yet done the recommended actions. The Shiftkey did not work last time, Esc or
Spacebar I have to try.

I have been searching if I can change grub by booting from CD but after changing etc/default/grub
it is expected to run "sudo update-grub" which is pretty hard if the system itself does not boot into a
commandprompt.

Any ideas on this?

If you have the Kubuntu install live medium, you can boot off that and then chroot into your system. That done, you can run programs like update-grub.

See, for example, https://help.ubuntu.com/community/LiveCdRecovery

Hi hydrurga,

a big thanks, in the link is exactly what have been looking for and did
not find.

I need to update/upgrade so I get the new graphic drivers because the
old ones let the system hang.

As english is not my mothertongue, I did not think of "LiveCdRecovery".

No problem Jan. Let us know how you get on.

Hi,

I will, the notebook that I wanted with dualboot Kubuntu/Win10 is running fine thanks to this forum.

Jan

Hi again,

I have the machine here. (Kubunti 18.04)

I managed to get to a root prompt, but when I want to run "apt update" and "apt upgrade"
a lot of errors occur because the repo-links cannot be resolved.

What could have caused that?

I see a file resolv.conf (coloured red) that I cannot edit as root.

Also I get a notification in the terminal "DEPEND" is yellow.

[DEPEND] Dependency failed for /boot/efi
[DEPEND] Depandency failed for Local file System
[DEPEND] Dependency faild for File System Check on /dev/disk/by-uuid/D72-EBA4.


Some hints?

[edit]

Following done after reading the fora:

/etc/resolv.conf already existed but was a link to a file in /run/systemd/resolve/ and I could not write to it.
I had to delete the link then recreate /etc/resolv.conf with the dns servers.

Then the chroot methode from the ubuntu wiki, but still getting that certain (most, still running) repos-links does not get resolved.
This is driving me insane.

I am running Kubuntu for many years now myself with little problems.
Never saw that a live-cd does not connect to the internet.

At last I have made an identical resolv.conf for the live-cd and the chroot(ed) system then it started downloading the updates.
Now hoping that it will help to start the system and does not hang in the startlogo again . . .

I have started the system about 20 x in recovery-mode.

I am a bit out of options, all recovery-menu-items do not help
me get beyond the kubuntu startlogo.

The network in recovery-mode is not working properly.

All searches in Internet resulted in exactly zero recent answers.

Seems this machine (Asus A4110) can only be a windows-machine.

We will have to reconsider what to do now.

I assume you ran command: sudo apt-get update then: sudo apt-get upgrade from within the chroot? If not, you may have upgrded the CD portion running in ram and not the installed Kubuntu.

According to Asus site, the specs for your system suggest it has Intel HD graphics, not Nvidia. I have posted a comment in another thread today where a member started getting similar issue with Debian and Intel HD graphics, this member was able to get it to the desktop by adding "nomodeset" as a boot parameter/argument. This would be done through one of the recovery menu options, I don't use Kubuntu, so you may have to check with Ubuntu/Kubuntu users on how to add this argument if you don't know how. Give it a try.
If it works, you can edit /etc/default/grub file once booted to add it there and then run command: update-grub. Just post a copy of the file in a code box if you need help with that part.

Thank you Brains,

clearly I updated from within the chroot, at least that part did work.

Considering Nvdia, you are right, just had another one with Nvidia problems that turned out to be the hardware which is soldered fix, so a new PC.

I will try "nomodeset", remember it from many years ago.

The system hangs in

[OK] Manage, Install and Generate Color Profiles.

after that nothing happens.

Hi,

in the end the user wants all kind of things that are difficult to realize in Linux,
because they are specific for Windows.

After two crashed harddisks and the main software being available for both Linux and Windows,
I decided to put him on windows 10 pro.

One system is now running, the other needs to get a new SSD build in.

It is hard to meet expectations that are beyond realistic, then he should have his windows
and use that.

The thread can be marked closed.
