I've got two problems:
My laptop does not wake up when it is suspended and it shows these messages in a black screen:
[349.417870] ACPI Error: [\_SB_.PCI0.LPCB.H_EC.ECWT] Namespace lookup failure, AE_NOT_FOUND (20170531/psargs-364) [349.417881] ACPI Error: Method parse/execution failed \_TZ.FN04._OFF, AE_NOT_FOUND (20170531/psparse-550) [349.417963] ACPI Error: [\_SB_.PCI0.LPCB.H_EC.ECWT] Namespace lookup failure, AE_NOT_FOUND (20170531/psargs-364) [349.417970] ACPI Error: Method parse/execution failed \_TZ.FN03._OFF, AE_NOT_FOUND (20170531/psparse-550) [349.418041] ACPI Error: [\_SB_.PCI0.LPCB.H_EC.ECWT] Namespace lookup failure, AE_NOT_FOUND (20170531/psargs-364) [349.418047] ACPI Error: Method parse/execution failed \_TZ.FN02._OFF, AE_NOT_FOUND (20170531/psparse-550) [349.418114] ACPI Error: [\_SB_.PCI0.LPCB.H_EC.ECWT] Namespace lookup failure, AE_NOT_FOUND (20170531/psargs-364) [349.418121] ACPI Error: Method parse/execution failed \_TZ.FN01._OFF, AE_NOT_FOUND (20170531/psparse-550) [350.802831] ACPI Error: [\_SB_.PCI0.LPCB.H_EC.ECWT] Namespace lookup failure, AE_NOT_FOUND (20170531/psargs-364) [350.802934] ACPI Error: Method parse/execution failed \_TZ.FN00._OFF, AE_NOT_FOUND (20170531/psparse-550) [350.925661] ACPI Error: [\_SB_.PCI0.PEG0.OFSV] Namespace lookup failure, AE_NOT_FOUND (20170531/psparse-550) [350.925780] ACPI Error: Method parse/execution failed \S_B.PCI0.PGOF, AE_NOT_FOUND (20170531/psparse-550) [350.925880] ACPI Error: Method parse/execution failed \S_B.PCI0.PEG0.PG00._OFF, AE_NOT_FOUND (20170531/psparse-550) [350.928692] NVRM: Xid (PCI:000:04:00): 79, GPU has fallen off the bus.
I've tried to disable the suspend mode when I close the lid, modifying the
/etc/systemd/logind.conf
file and the/etc/UPower/UPower.conf
file but none of those worked.
What should I do?
