Lithium fails when starting Light Display Manager

I am trying to install Lithium (dual boot) on a new Asus Zenbook UM433DA-NH74. FYI, it has an AMD Ryzen 7 3700U processor and a Radeon RX Vega 10 integrated graphics processor.
During startup I get the following message:

[FAILED] Failed to start Light Display manager.
See 'systemctl status lightdm.service' for details.

Performing 'systemctl status lightdm.service' yields (here is everything since I am unsure what is important):

  Loaded: loaded (/lib/systemd/system/lightdm.service; indirect; vendor preset: enabled)
  Active: failed (Result: exit-code) since Sat 2020-09-12...
    Docs: man:lightdm(1)
 Process: 1338 ExecStartPre=/bin/sh -c [ "$(cat /etc/X11/default-display-manager 2>/dev/null)" = "/usr/sbin/lightdm" ] (code-exited, status=0/SUCCESS)
 Process: 1340 ExecStart=/usr/sbin/lightdm (code=exited, status=1/FAILURE)
Main PID: 1340 (code=exited, status=1/FAILURE)

Running /usr/sbin/lightdm yields:

** (lightdm:1407): WARNING **: 14:24: Error getting user list from org.freedesktop.Accounts: GBBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name org.freedesktop.Accounts was not provided by any .service files
** (lightdm:1407): WARNING **: 14:24: Could not enumerate user data directory /var/lib/lightdm/data: Error opening directory '/var/lib/lightdm/data': No such file or directory

This occurs both on live and disk installs.

Note that before this happens on disk installs, it asks for iwlwifi drivers, which I successfully apply

How do I fix this issue, or, are there any other diagnostics I can provide to help?

Thanks much.

Re: Lithium fails when starting Light Display Manager

The other OS, is that another Linux or Windows?
Can you boot live Ubuntu och plain Debian Live?

Have you examined linuxcompatability for your hardware? I guess it is rather new hardware.

Have you backports enabled and updated drivers/kernel from backports?

Re: Lithium fails when starting Light Display Manager

Hi,
got the exact same problem here on my new desktop PC. I am running bunsenlabs lithium only.
Str-Alt-F1 takes me to the terminal so the systems seems alright. Installing XDM does not fix the problem, but the error message is not posted during boot.

Installed Debian just to check - same results.

Ubuntu works however but I would really rather run bunsenlabs on this machine.

I kind of have the feeling that the graphic driver is causing this but I am not knowledgeable enough to investigate deeper.

Does anyone have an idea??

Thanks,
atzalan

Re: Lithium fails when starting Light Display Manager

Could you just try uninstalling lightdm and log in from the tty to see if X11 + openbox work fine.

Hmmm, why did you think xdm should be better than lightdm? Xdm I think, has not been updated since 2015...
Did you see boot error when lightdm was installed but they disaperade win running xdm? Do you run boot without splashscreen? (GRUB_CMDLINE_LINUX=" " in /etc/default/grub and update grub?)

Installed Debian just to check - same results.

You did not just try with live boot?

Ubuntu works however but I would really rather run bunsenlabs on this machine.

Then, there should bee linux support in more recent kernel/drivers. Try enable backport and install backport kernel / graphic driver.

I kind of have the feeling that the graphic driver is causing this but I am not knowledgeable enough to investigate deeper.

X-related errors gets into /var/log/Xorg.0.log.

You can also run hw-probe

Yes, It sounds like a driver issue. I believe rbh has already given you the solution with his backports answer. smile


You can try tthe steps outlined in the thread here:
https://forums.bunsenlabs.org/viewtopic … 86#p109586

Make sure to comment out the unstable line when done.

Because I found this solution in another forum for a similar problem and it was easy to try out.

However you are right. It is most definately to do with the video driver.
/var/log/Xorg.0.log showed

Cannot run in framebufer mode. Please specify busIDs for all framebuffer devices

lspci identifies the video card as

VGA compatible controller: Intel Corporation Device 9bc8 (rev 03)

What is the right firmware package to update? Is that firmwar-misc-nonfree?

Thanks again

Try:

inxi -xx -G

for specific graphics driver info.

You can update any/all of the firmware packages. They are standalone, and simply won't work if not called by your system.
 
Install the latest kernel from unstable or experimental, and upgrade any/all of the firmware packages that you need.

You seems to have droped essentiel output info from lspci.
Command "lspci -nn" on my machine, gives:

01:05.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] RS880 [Radeon HD 4250] [1002:9715]

The last part is [vendor:device] codes. I serched for "lspci vendor 9bc8" and found: https://pci-ids.ucw.cz/read/PC/8086/9bc8
Main -> PCI Devices -> Vendor 8086 -> Device 8086:9bc8 - UHD Graphics 630

Is that realeye your Graphic card?

What is the right firmware package to update? Is that firmwar-misc-nonfree?

You have given insufficent information to answer the question.

you ought to have a look at hw-probe, You just run it, and get a weblink to all information about your hardware.

Re: Lithium fails when starting Light Display Manager

If your graphic card is Intel UHD Graphics 630, it is supported in linux from kernel 5.2

Test first to install kernel and upgrade firmware from backports. See https://backports.debian.org/Instructions/ for howto.

Re: Lithium fails when starting Light Display Manager

Sorry, here is what I did:

echo deb http://deb.debian.org/debian buster-backports main contrib non-free | sudo tee /etc/apt/sources.list.d/buster-backports.list
sudo apt-get update
sudo apt install -t buster-backports linux-image-amd64
sudo apt install -t buster-backports firmware-linux firmware-linux-nonfree firmware-realtek

reboot and enjoy Bunsenlabs Lithium
