No DM/Session after UEFI update

I had a perfectly working system until i decided to update the UEFI on my motherboard.

After the UEFI update.  I boot directly into a grub prompt.  I used a live USB to rebuild grub entries and was able to boot into a tty1 with no GUI. Enable lightdm results in lightdm being displayed, but it always fails to start the xfce session.

If I shutdown completely, turn my pc on, log into tty1 then execute "startx /usr/bin/startxfce4" I can start the session and use my pc just like nothing ever happened.

I've tried different DM, i've switch to systemd-boot, added "exec startx /usr/bin/startxfce4" to .bash_profile, nothing works.  Only the exact steps above.

What is going on?

Re: No DM/Session after UEFI update

Sounds like a race condition. Try adding your display driver module to the initramfs (early KMS).

Re: No DM/Session after UEFI update

Adding it to the intramfs image? Is there a resource about doing that?

Edit /etc/mkinitcpio.conf and regenerate it?

Thanks i was looking at this:

https://wiki.archlinux.org/index.php/Mi … tcpio.conf

Should a UEFI update have effected any of that?  I did my other attempted repairs cause this?

Enable lightdm results in lightdm being displayed, but it always fails to start the xfce session.

What does the LightDM log say about that? Have you even checked the journal?

Not that I claim to know why starting it via your bash profile does not work... but per XFCE's wiki page, you should either just run

startxfce4

or

[...]or add

exec startxfce4

to Xinitrc.

Re: No DM/Session after UEFI update

I looked at the Xorg log.  It tries to load screen 0 and 1 but can't find either and unloads amdgpu.

I will look at lightdm log / journal tonight

Thanks for the help
