Configuring org.conf to use only one screen solved the issue.

Configuring xorg.conf to use only one screen solves the issue.

Xorg.0.log for session with only one screen configured

This is Xorg.0.log from start of session with only one GPU configured.

Clearly this is a workaround, but I can use the whole gnome desktop.
The problem seems due to IGPU+DGPU

After reproducing the problem, please run 'bt full' at the gdb prompt and attach the output of that.
