No graphic interface since last update

Hello,

my laptop is buggy since I updated it two days ago. The last one I did was two months ago. The laptop is a XPS 15 9560. I still have access to terminal mode via tty,

As I suspected a graphic driver issue, I looked a bit in that way, tried to disable GPU with bumblebee, acpi_call, but there's no changes. I tried to change a bit my Xorg.conf, nothing. And in the Xorg.log nothing there are no errors, just warnings. (it's the same for dmesg).

I also tried to rollback updates by using archive repositories, but it doesn't work either.

I'm a bit lost now, where should I look next ?

Here is my xorg log : https://dpaste.com/3EJXVVWA2

I would have shared output of journalctl too but the output is too large to be uploaded

Try adding i915 to your initramfs: https://wiki.archlinux.org/index.php/Ke … _KMS_start

As for the journal, it's seldom useful to post the entire journal, a single boot shouldn't be too large though

sudo journalctl -b #For the current boot

Even with i915 module it doesn't work.

I found another pastebin like that accepts larger files, here is the output of journalctl -b : https://termbin.com/hy9w

Re: No graphic interface since last update

That journalctl -b output is far from complete,
check https://wiki.archlinux.org/index.php/Li … in_clients for alternatives.
(pay attention to the green tipbox)

Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.

clean chroot building not flexible enough ?
Try clean chroot manager by graysky

Re: No graphic interface since last update

I tried other clients but few were working for me. I retried with wgetpaste but splited the file to be under size limit.
Here are the two parts :

I'm still trying to share it into one part

Thanks for the greenbox advice

Re: No graphic interface since last update

If I disable gdm, how should I start it when my system is booted ?

When I run "X" with my non root user I get that error => "(EE) parse_vt_settings: Cannot open /dev/tty0 (Permission denied)"
When I run "sudo X" I got a black screen, it's similar as the behavior when gdm is enabled. Should I paste the log of xorg in that scenario ?

I'm still trying to figure out if I got a kernel or a xorg issue

login as root, then run systemctl start gdm.service

Re: No graphic interface since last update

Thanks, but the result of that leads to the same issue : black screen (with the underscore cursor blinking)

Good news : I restored a graphic interface.
For that I installed kde, enabled sddm service, and now I got something working.

Bad news : Working but not entirely, I'm not able to launch terminal (in kde, ttyX works fine), maybe other things are broken too.

And I would like to understand what's wrong with gdm. Because right now I can't trust my computer, I feel like it can fail at anytime.

So far, I think that it is not about Kernel configuration, it is not about X (with sddm Xorg and Xwayland are running), so it is maybe about gdm's config ? But I don't remember that I modified that, in fact I never made that, so I can't have a better guess yet.

EDIT : Even if I installed KDE it seems that I booted with GNOME

Re: No graphic interface since last update

The line #WaylandEnable=false was already uncommented.

I tried to comment it and boot with gdm again, but I still got black screen.
