Hi All, New laptop uses nvidia optimus. Able to get in to X using 2.6.35, but doesn't appear to be possible to use the nvidia card using vgaswitcheroo.
Some details: U35JC 1.0 00:02.0 VGA compatible controller [0300]: Intel Corporation Core Processor Integrated Graphics Controller [8086:0046] (rev 18) 01:00.0 VGA compatible controller [0300]: nVidia Corporation Device [10de:0a70] (rev a2) Biggest problem with this laptop at the moment is that it seizes when trying to suspend, most likely due to gfx issues. There are a lot of symptoms of what appear to be acpi issues (?) : 1. I have two /proc/acpi/video/GFX0 directories: [ 7.836571] ------------[ cut here ]------------ [ 7.836582] WARNING: at /build/buildd/linux-maverick-2.6.35/fs/proc/generic.c:583 proc_register+0x103/0x1e0() [ 7.836585] Hardware name: U35JC [ 7.836588] proc_dir_entry 'video/GFX0' already registered % ls -1 /proc/acpi/video/ GFX0 GFX0 2. Some kind of ACPI execution error: [ 7.999440] ACPI Error (psparse-0537): Method parse/execution failed [\_SB_.PCI0.GFX0._DSM] (Node f702a978), AE_AML_OPERAND_TYPE [ 7.999523] failed to evaluate _DSM: 12291 [ 7.999557] ACPI Error: Needed [Buffer/String/Package], found [Integer] f6950870 (20100428/exresop-590) [ 7.999561] ACPI Exception: AE_AML_OPERAND_TYPE, While resolving operands for [OpcodeName unavailable] (20100428/dswexec-445) [ 7.999566] ACPI Error (psparse-0537): Method parse/execution failed [\_SB_.PCI0.GFX0._DSM] (Node f702a978), AE_AML_OPERAND_TYPE [ 7.999621] ACPI Error (psparse-0537): Method parse/execution failed [\_SB_.PCI0.PEG1.GFX0._DSM] (Node f703fba0), AE_AML_OPERAND_TYPE [ 7.999681] failed to evaluate _DSM: 12291 I've still got win7 installed if that helps to collect any acpi diagnostics.
