Manjaro (KDE) not booting after BIOS splash screen - switching from old nvidia to 6900 xt

Hi everyone!
Very basic manjaro user here. I’ve already looked around this forum for a solution to my problem but could not find one cause other threads do not relate enough to my problem.

As from title, I just changed from a GTX 960 to a AMD 6900XT (Sapphire NITRO+ SE), and I get no graphical environment after boot, I can enter the BIOS but can’t go further. Nonetheless, I can obtain graphical output with live usb and I can see that propietary drivers are installed.

But I have no idea what I could do to solve the problem. Some other threads refer to modifying some parameters through TTY interface but I can’t enter it because my login credentials do not work (which could be a problem, in general). Also, others refer to uninstalling and re-installing drivers which I can’t do as I can’t apply any suggestion if code is not provided since I’m a noob.

Please can anyone dedicate some time to help me??
I thank you all a lot!

Hello,

If you can either chroot in or boot into runlevel 3
(see [HowTo] Resolve an unbootable Manjaro (black screen, login failed, cant boot, etc))
Then lets look at your drivers:

mhwd -l -li

If you have, for example video-nvidia then remove it:

sudo mhwd -r pci video-nvidia

Then maybe try to force reinstall the open drivers (this should be your only gfx profile):

sudo mhwd -f -i pci video-linux

Then reboot (systemctl reboot)

Thanks for the fast reply!

I could get to my system through chroot and I actually have some nvidia drivers installed (very confused now), but I can’t get rid of them due to some depencies required by cuda.

Please try to provide actual output when available.
(if needed see this: [HowTo] use public command-line pastebin services without installing anything!)

I suppose you have to remove some packages then (again I do not know what you have installed):

sudo pacman -Rns cuda

Then continue with the removal of drivers as above.

But I’m on this forum from another pc (since the one with the issue is not usable), does your guide still apply?

Anyway, I was stuck in a process and I hard rebooted the machine to start again (cuda removal didn’t work cause directory was not found), now trying to boot the pc stops at a command line saying:

[FAILED] Failed to start pkgfile database update.

Ok let’s start again, I rebooted through the live usb mode and now using terminal (instead of “Ctrl+Alt+F2” mode) so I can copy-paste the output from command line.

This is what I get with

mhwd -l -li

Sure…

Just to be clear … you have chrooted into the existing install? via, ex:

manjaro-chroot -a

You will need to have a working internet connection to install/update packages.
So just connect in your live session before continuing with the commands.

Yes, I chrooted with

manjaro-chroot -a

I am connected to my home Wi-Fi since the beggining of the process

Ok. Well lets sort the mirrors and resync:

sudo pacman-mirrors -f && sudo pacman -Syu

(this will query all mirrors globally unless you have set a custom list … add a number if you want to shorten the amount of queries, ex: sudo pacman-mirrors -f10)

Please report if it produces more errors or does not finish properly.

This is the output

sudo pacman-mirrors -f && sudo pacman -Syu

I am speed testing the Wifi connection and I get over 200 Mbps in download and 94 in upload

It appears there is some problem with resolving the mirror domains.
pacman-mirrors thinks you have no internet at all.

…I wonder … taking a known working german mirror … can you download/contact it using curl?

curl -O https://mirror.23m.com/manjaro/stable/core/x86_64/core.db

If the file does download … what are the contents?

less core.db

Here

curl -O https://mirror.23m.com/manjaro/stable/core/x86_64/core.db
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
  0     0    0     0    0     0      0      0 --:--:-- --:--:-- --:--:--     0curl: (6) Could not resolve host: mirror.23m.com
less core.db
core.db: No such file or directory

This shows again symptoms of no connection.
Are you behind some sort of firewall? You can confirm internet otherwise works?
Maybe there is a bad DNS configuration?

ping manjaro.org -c3
dig manjaro.org

I am live chatting with you, I can use my mail. I get facebook, youtube, basically anything…
Never had problems with the connection.

ping: manjaro.org: Temporary failure in name resolution
ping: manjaro.org: Temporary failure in name resolution

But you cannot in any of the other tests (did you do ping or dig?)
Are all of these mentioned connections through your browser?
(by default modern browsers use their own DNS)

EDIT. Ah theres the dig and ping.
They dont work either … and fail for the same reason (domain name resolution).
I am really starting to believe it is a DNS problem.
Have you configured that in any way?

Oh and another test … pinging IP’s directly (will do google)…

ping 8.8.8.8 -c3

No, but I’m starting to believing you as well, software manager can’t install anything for “No database found” and I guess it is the same problem.
What should I do?

PING 8.8.8.8 (8.8.8.8) 56(84) bytes of data.
64 bytes from 8.8.8.8: icmp_seq=1 ttl=116 time=5.92 ms
64 bytes from 8.8.8.8: icmp_seq=2 ttl=116 time=6.18 ms
64 bytes from 8.8.8.8: icmp_seq=3 ttl=116 time=6.06 ms

--- 8.8.8.8 ping statistics ---
3 packets transmitted, 3 received, 0% packet loss, time 2003ms
rtt min/avg/max/mdev = 5.923/6.054/6.180/0.105 ms

EDIT
This should have not worked, right?

First thing … please make sure your date/time/clock are properly set.

If there are still problems … we can set the DNS …

If you use Network Manager then you should be able to ‘configure network connections’ or open the connection properties (there are slightly different views depending on the desktop, etc)

In the IPv4 section; under Method; select “Automatic (Only Addresses)”; and input DNS servers
(cloudflare is 1.1.1.1 and 1.0.0.1)


It just further makes DNS problem likely as it cannot lookup the domain and translate google.com to 8.8.8.8 but it can go to 8.8.8.8 directly.

Date and Time were not correct :sweat_smile:
I hope that was not causing the entire problem.
Anyway I also set the DNS following your instructions

Set and applied … (you may need to restart the connection)…
So … how about dig or ping now?

ping manjaro.org -c3
dig manjaro.org

If it looks normal, without any more domain resolution errors …

Then continue on to pacman:

sudo pacman-mirrors -f && sudo pacman -Syu
ping: manjaro.org: Temporary failure in name resolution
bash: dig: command not found
