Post Live Installation Login Fail

Postby houtje » 2020-01-30 09:28

So, yesterday I installed Debian 10 (first time user) successfully from the live setup (the non-live didn't work because the GRUB installation failed)

Everything worked great, but I had to find a fix for the screen tearing issue of my GPU. I did find the fix (manually create and edit the /X11/xorg.conf file to specify display parameters (I'm using a UHD display over displayport, perhaps that could have caused an issue). But before I found the fix, I tried all sorts of stupid shit and ended up breaking Debian. But, lesson learned, and today I'm doing a fresh install.

BUT...

I followed exactly the same installation procedure I did yesterday, but for some weird reason when I first boot from the fresh installation, the login screen shows my REAL name in stead of the username and it doesn't accept my password. I have taken keyboard settings into account (I'm from Belgium) trying to type in Qwerty in stead of Azerty (which was used to create the PW).

BUT... as I'm writing this, I finally managed to login :)

This *seems* to be the fix: in Debian Live, before installing Debian to your boot device, you have to set the keyboard layout to correspond to the one you're going to use in the installer. In the installer itself you then apply the same keyboard layout.

Then, if you boot, there shouldn't be an issue with the password. Then, first time in Debian, you should AGAIN re-set the keyboard layout once again.

This is really weird.

I'm not even sure if I fixed it... because when I run a sudo command in Konsole, it prompts the following message:

We trust you have received the susual lecture from the local system Administrator. It usually boils down to these three things:
- respect privacy
- think before you type
- with great power comes great responsibility


So yeah... this is different from yesterday's install and I don't know why because I'm using EXACTLY the same USB stick to boot into Live as yesterday. I mean... I have no idea what sorcery this is.

So I don't really know if I can trust the install I currently have... should I perhaps use a different USB stick, download the .iso again and try it again?

The whole reason why I'm re-installing Debian is so that I can be confident that all my packages are stable and not corrupt... I want to have a stable system. This is going to be my editing workhorse and I'm done with Windows 10. But I'll be using it professionally, deadlines are holy, so stability is paramount.

Anyway, hi, I'm Wouter, nice to meet you all and to become a part of this :)

Hi and welcome to the forums!

You're post is not clear as to what to problem really is.
Did you eventually install Debian, or are you just running it from the live session...?

This shouldn't make any difference, although I would advise you to use the main installer (not Calamares) because the latter doesn’t cover all the advanced features of the debian-installer.

We trust you have received the susual lecture from the local system Administrator. It usually boils down to these three things:
- respect privacy
- think before you type

This is normal and appears the first time you use 'sudo'.

Info we need from you:
- system specs
- preferred Desktop Environment to install (from what I can tell KDE?)
- The partitioning scheme/configuration you use
- Errors you get/got during installation

- i7 hexacore, x99s sli plus, 16GB DDR5, gtx970
- KDE Plasma (haha, awesome you deduced it from so little information!)
- GPT I would assume because the mobo is UEFI?

this is what sfdisk returns:

- The error I was getting with the netinstall was that the GRUB boot loader couldn't be written to the disk, it failed. The live installation process installed flawlessly (besides the keyboard thing but I managed to figure it out by conforming the keyboard settings within the live session itself)

during boot I always get a small notice, something about the CPU cores being unable to be identified or something among those lines. But in reality, the system runs really smooth and I can run heavy tasks without it behaving weirdly. I'm a Davinci Resolve user and that's a fairly hefty application. Compared to how it ran on windows, there is no real difference... it does load faster on linux though. But I'll have to actually do a project with it in Linux to really be able to put it to the test.

In any case, I'm pretty happy with the system so far! One thing that is difficult about Debian (but also why I chose it) is that it is a bit more difficult to find solutions. But I understand this is because we don't want to trade quick solutions for stability.

I even got Samba to finally work lol. This is important because the system will be connected to a 10G Freenas box.

There is a 10G NIC in the mail and I'm already wondering about how I'm going to get that installed! It's an intel chip sfp+ interface and it has linux driver available from the website... but is that even safe to install in a debian environment? Is there a way we can backup the system quickly before trying wonky shit? Also, is it safe to leave "contrib" and "non-free" into the /sources.list ? Or is it good practice to remove that after you're done?

Hehe, a lot of question, sorry :D

There are no risks in keeping your 'contrib' and 'non-free'.

Installing proprietary drivers from the manufacturer's site is not recommended. You should first look and see if the kernel recognizes the device after plugin:
Code: Select all
lspci

Look for 'Ethernet controller' in the output.

Regarding your question about backups, there are several possibilities and you will have to determine for yourself which one best suits your needs.
Some examples:
- rsync
- tar
- ..
