amsk98 TwinCitiesTransplant thank you
You're welcome. I came to the forum looking for an answer to my problem, and since it seemed to be the same as yours I thought I'd chime in on this thread. Hopefully we can noodle our way to a solution that works for us both (and to any other users who might be having a similar problem).
I followed your instructions and mesa-amber replaced mesa as you described, but I still wasn't able to get to a DE on the live USB. When I restarted sddm with Wayland, it gave me a black screen for several seconds and then the same
Plasma Failed To Start message popped up. Out of curiosity, I cycled through the other virtual terminals (Ctrl-Alt-F-keys) and saw a black screen on terminal 3. I switched back to TTY2 and did a
who, which showed me that the live user was logged into both TTY2 and TTY3:
live tty2 2022-06-30 20:03
live tty3 2022-06-30 20:06
Ctrl-Alt-F3 just showed me a black screen (I had regular terminal login prompts on TTY4-TTY6), so I switched back to TTY2 to see what was happening with
w. Rather than writing it down, I started a
script session and got this result from
20:11:37 up 8 min, 2 users, load average: 0.13, 1.01, 0.64
USER TTY LOGIN@ IDLE JCPU PCPU WHAT
live tty2 20:03 1.00s 0.24s 0.01s script /mnt/home/bne/Desktop/typescript30a
live tty3 20:06 8:42 21.75s 0.16s /usr/lib/telepathy/mission-control-5
I then edited sddm.conf as before and restarted sddm, and I got the same black screen with the mouse pointer as in my previous experiences. Back on TTY2,
w was showing me the same thing as before on TTY3, and when I Ctrl-Alt-F3 to TTY3 I got a black screen at first, and then a mouse pointer appeared after several seconds.
I'm not trying to add to the complexity of the problem. I'm reporting the TTY3 thing because I didn't expect to see anything there, and I don't know if that's expected behavior. It could be a red herring.
I don't know if this is helpful to you at all. If you want me to repeat these steps and try to capture some more logs, feel free to let me know and I'll try to grab it.
