Elementary OS 8 Login Issues

[Cotywio]

Hello,

Apologies as I'm not sure which repo I should report this in, upon downloading the Elementary OS 8 Early Beta (at least March 7th - 12th) I am having the following issues:

1. When I click into "Try Demo Mode" I get the following message:
   

2. When I install via the option to wipe the entire disk, with no encryption and with/without third-party drivers, I'm able to get here:
   

3. If I type in my password, it brings me to this screen, all black except for the panel icons. If I move my mouse to hover over the icons, they disappear and I can no longer see anything.
   

   Not sure if this is helpful, but including .xsession-errors found in my user profile:
   a.
   

If I try via Pantheon (Wayland), I receive a completely black screen with no panel icons at all.

Platforms tested on (booting in EFI mode):

• VirtualBox
• Dell Inspiron Laptop
• Dell Latitude 3410 Laptop
  Media created with Rufus & BelenaEtcher with similar errors for both.

Thank you!

I too have this problem and I've noticed others at Reddit hoping for a solution also. That said, isn't "DISPLAY=:0.0" the correct environment variable?

Switch to tty1 (Ctrl+Alt+F1) enter your username and password, then execute coredumpctl debug gala > backtrace.txt and upload backtrace.txt here please

[Cotywio]

Ran this and I'm receiving a "No match found." message with no data in backtrace.txt

[lenemter]

Hm... Then can you please debug it manually?

1. Switch to tty1 by pressing Ctrl+Alt+F1
2. Install gdb (sudo apt install gdb)
3. Run DISPLAY=:0 gdb gala
4. In gdb prompt run set logging on
5. Then run -r --display=:0
6. Gala will crash
7. Run bt

After all of this please send the gdb.txt file from your home directory

Received some output there, attached! Thanks for the help with this. :)

I put something about this out on Mastodon, and the official Elementary page responded, apparently something is broken on the Ubuntu end as of now.

[m3justchris]

Can anyone confirm if this has been fixed yet?

Not entirely sure, I downloaded the ISO as of two days ago, and couldn't get past an initial black screen on a few different systems.
