I am running Ubuntu 20.04 on an Alienware 17 R4 with an NVIDIA GeForce GTX 1070. I recently did a software update which caused the system not to resume after suspend so I changed the driver from proprietary tested to proprietary server (version 460 on both).
Now the system won't suspend at all. It basically reboots when suspending from the GUI or terminal. I've tried editing the GRUB file by adding:
mem_sleep_default=deep
to the GRUB_CMDLINE_LINUX_DEFAULT line editing the logind.conf file to no avail.
I ran dmesg in the terminal and received these errors:
[ 0.510392] tpm_crb MSFT0101:00: [Firmware Bug]: ACPI region does not cover the entire command/response buffer. [mem 0xfed40000-0xfed4087f flags 0x200] vs fed40080 f80

I've been at this all day and haven't found a solution. This is my work computer so I need this resolved quickly. Right now I have suspend on battery power turned off. Thanks in advance.
