apport information ** Attachment added: "ProcEnviron.txt" https://bugs.launchpad.net/bugs/1788113/+attachment/5178448/+files/ProcEnviron.txt
** Description changed: - If I try to switch to intel mode on my Zenbook Pro UX550 and then reboot, I end up without a graphical session. GDM does not start even if it seems to be trying to for many times. I see a systemd message that the dGPU could not be switched off. Also, I get a flickery screen on TTYs until GDM gives up with the screen alternating between the TTY and teh systemd textual log. Once that stops flashing I manage to prim-elect nvidia and reboot cleanly. This is certianly better than before teh update but it does not fix the situation fully. I am using bionic with all updates applied. - --- + If I try to switch to intel mode on my Zenbook Pro UX550 and then reboot, I end up without a graphical session.
