Hey All,

I was using Liquorix kernals for ages until 6.12 came out and now I cant see anything on the screen once it boots.
Kernal 6.11 works fine, I also tested XanMod works fine on 6.12 and 6.13 along with Stock 6.8 I have no issues.

Useing anything Liquorix 6.12 and above it boots as normal and shows the "splash" screen text and when it would typically show the Mint logo the screen goes dark and I get a no input signal on my monitor and never shows my desktop.

Tried simplifying my monitor setup and directly connected 1 monitor using a known good cable and same issue.

Any help or obvious errors in the logs I missed would be greatly appreciated as I would prefer to use the Liquorix kernal

Heres the inxi from Xanmod kernal as I dont have Liquorix 6.11 anymore

Along with the journalctl -b -l -k output : https://pastebin.com/kUU7kkZ3

Good bug report.

Try adding one more thing:

cat /var/log/Xorg.0.log | tail -n 50. Or just the whole file.

For display start failures, generally the actual error is in the last 50 lines of the xorg log.

Double check you don't have a hardcoded monitor location in xorg.conf file, or in sub files.

Since you have amdgpu, that gets rid of the main common cause for desktop failing to start but booting fine.

You should be able to ctrl + alt + f1 or f2 to the console screen, where you can login and grab the data on failure.

It's weird, but when I first ported over the first 6.13-1 for MX Linux, installed, and booted to it, I also got a black screen the first few times, with a little flashing dash cursor in the upper left. After a few hard resets and a boot to the 6.12 kernel, it cleared up and has never recurred on 6.13. This is also on amdgpu with a backported Mesa and firmware on top of Bookworm.

I saw this in a few other posts but I dont even get a cursor and I did try to change the TTY to get more info but does nothing like the screen just went into standby.

I was temped to setup an SSH connection to see if it actually boots up and see if I could pull anything.
Looking at the Xorg.0.log.old I think there might be something interesting.
It mentions no screens found and Screen 0 deleted because of no matching config section.

It looks like the Liquoix kernal doesnt find /dev/dri/card0 and then gives up where my current kernal sees my card is at /dev/dri/card1 and continues with that instead, I dont know if that makes sense or not just an observation between the 2 log files.

I put the full file on pastebin again - Xorg.0.Log.old --> https://pastebin.com/9eRFMnkE

If your previous boot was on Liquorix and you successfully boot into a different kernel, you can run sudo journalctl -k -b -1 to retrieve all the kernel logs from the previous boot.

Try and that and post it on some type of paste bin service for us to look at.
