I just installed 12.1 but my laptop can’t handle gnome3. It runs fine in fallback the first time. But when I try to log in again, the default login screen is gnome3. I can login if I select “other” and type my username and password. Is there some way to revert to the fallback login screen on startup? Thanks for any help with this.
Have you done >user >System Settings >Info >Graphics >Forced Fallback Mode >On ?
I have a similar problem on an old laptop. If I login to gnome 3, it logs me in just fine. But then it crashes as soon as I try to do anything. So it doesn’t stay up for long enough to switch to fallback.
I think this will work: Log into icewm at the login screen. Then open a terminal. Then run the command:
gsettings set org.gnome.desktop.session session-name gnome-fallback
The logout of icewm, and try a gnome login again. It should put you in fallback mode.
If that does not work, then try:
Reboot the system. On the grub boot screen, type in “nomodeset” (without the quotes) in the kernel parameter line.
That should allow you to login to gnome in a stable fashion.
When in, use System Settings → System Info → Graphics
and set the “force fallback mode” to On.
Hi
Check the Release Notes

Thanks for your replies. I seem to have found a workaround. I was using passwordless login (or whatever it’s called). I turned that off and now I don’t have the problem anymore. Now my only issue is trying to get my orinoco onboard wlan to work.
