Yesterday I started qubes-dom0-update and it installs kernel-4.19. Looks great!
But it is not starting graphical login anymore.
I did sudo dnf downgrade kernel and it didin't work.
I had to change grub to fix.

Do you see text login available? Maybe on tty2 (alt+ctrl+f2)? You can
login there and see lightdm service status (`sudo systemctl status
lightdm`), which is responsible for the graphical login. If it's failed,
what it says there (you should have few log lines there)?
It would be also useful to check X server log - /var/log/Xorg.0.log -
especially if you see any error message at the end.

You should be able to choose older version in grub menu.

I'm having the same problem.

Linux console is working fine, lightdm is also working correctly IMO. Nothing out of the ordinary in /var/log/Xorg.0.log nor /var/log/lightdm/ligthdm.log. But /var/log/lightdm/x-0.log has some errors https://hastebin.com/apamuvazey.txt
as do dmesg https://hastebin.com/tijufefego.txt (only errors attached)
Both are radeon related (I have Radeon HD 7790).

Sergio do you also have a radeon card?

That's what works for me, no problems at all on 4.14.74-1 kernel.

Yes. Mine is RX-560.
I already installed the amdgpu and vulkan drivers, but it still not working with kernel 4-19. Works fine with 4-14 and the drivers too.

Yes, It fails because the video driver. My card is a radeon rx-560 but there was no radeon driver installed. It was working with vesa driver.
Now I already installed it but the error continues when I choose kernel-4-19 on grub.
The testing repository was enabled in my yum repo cfg.

Don't worry, it is working fine with kernel-4.14. If you need, there is some log files bellow.

Yes, that was what I did and I change to automatically boot the kernel-4.14.

I love Qubes! Thank you!!

rx 560? Have you tried adding 'amdgpu.dc=1' to the kernel parameters?
hd7790 should work fine using the old radeon driver though.

Yes. It is working with kernel 4-14 and this boot option, thank you!
