I have ignored that the whole time: Sep 21 09:38:30 hermann kernel: ACPI Warning: \_SB_.PCI0.PEG_.VID_._DSM: Argument #4 type mismatch - Found [Buffer], ACPI requires [Package] (20130823/nsarguments-97) Sep 21 09:38:30 hermann kernel: ACPI Warning: \_SB_.PCI0.PEG_.VID_._DSM: Argument #4 type mismatch - Found [Buffer], ACPI requires [Package] (20130823/nsarguments-97) Sep 21 09:38:30 hermann kernel: ACPI Warning: \_SB_.PCI0.PEG_.VID_._DSM: Argument #4 type mismatch - Found [Buffer], ACPI requires [Package] (20130823/nsarguments-97) Sep 21 09:38:30 hermann kernel: ACPI Warning: \_SB_.PCI0.PEG_.VID_._DSM: Argument #4 type mismatch - Found [Buffer], ACPI requires [Package] (20130823/nsarguments-97) Sep 21 09:38:30 hermann kernel: ACPI Warning: \_SB_.PCI0.PEG_.VID_._DSM: Argument #4 type mismatch - Found [Buffer], ACPI requires [Package] (20130823/nsarguments-97) Sep 21 09:38:30 hermann kernel: ACPI Warning: \_SB_.PCI0.PEG_.VID_._DSM: Argument #4 type mismatch - Found [Buffer], ACPI requires [Package] (20130823/nsarguments-97) Sep 21 09:38:30 hermann kernel: ACPI Warning: \_SB_.PCI0.PEG_.VID_._DSM: Argument #4 type mismatch - Found [Buffer], ACPI requires [Package] (20130823/nsarguments-97) Sep 21 09:38:30 hermann kernel: ACPI Warning: \_SB_.PCI0.PEG_.VID_._DSM: Argument #4 type mismatch - Found [Buffer], ACPI requires [Package] (20130823/nsarguments-97) Sep 21 09:38:30 hermann kernel: ACPI Error: Field [TBF3] at 270336 exceeds Buffer [NULL] size 262144 (bits) (20130823/dsopcode-249) Sep 21 09:38:30 hermann kernel: ACPI Error: Method parse/execution failed [\_SB_.PCI0.PEG_.VID_.GETB] (Node 0xfffff800044ef740), AE_AML_BUFFER_LIMIT (20130823/psparse-553) Sep 21 09:38:30 hermann kernel: ACPI Error: Method parse/execution failed [\_SB_.PCI0.PEG_.VID_._ROM] (Node 0xfffff800044ef780), AE_AML_BUFFER_LIMIT (20130823/psparse-553) Sep 21 09:38:30 hermann kernel: ACPI Warning: \_SB_.PCI0.PEG_.VID_._DSM: Argument #4 type mismatch - Found [Buffer], ACPI requires [Package] (20130823/nsarguments-97) I'm no ACPI expert, but could this message inform me about some ACPI issues with selecting the right device/display socket? I can also provide an ACPI dump, if requested and secure. Oliver
