I tested this on a Dell XPS 15 9570. When using the kernel is 4.18.12-041812-generic, boot options: acpi_rev_override=5 acpi_osi=Linux scsi_mod.use_blk_mq=1 and selecting nvidia I don't get any graphical login.I have to switch to intel via the recovery root console.
When selecting intel, power consumption is between 8 and 9 W which means nvidia GPU is off. After standby the screen is corrupted. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gdm3 in Ubuntu. https://bugs.launchpad.net/bugs/1778011 Title: SRU: PRIME Power Saving mode draws too much power To manage notifications about this bug go to: https://bugs.launchpad.net/hwe-next/+bug/1778011/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
