Hi, Made few tests and searches in SSDT files and find 3 methods : \_SB_.PCI0.P0P2.PEGP._STA : supposed to give actual status of the discrete card \_SB_.PCI0.P0P2.PEGP._OFF : disable the card \_SB_.PCI0.P0P2.PEGP._ON : enable the card
I made tests and I have more or less win .... #on intel (i915) card without any switch echo '\_SB_.PCI0.P0P2.PEGP._STA' > /proc/acpi/call cat /proc/acpi/call 0xf -> I assume that means that the card is active ... lspci |grep VGA 00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 02) 01:00.0 VGA compatible controller: ATI Technologies Inc Manhattan [Mobility Radeon HD 5000 Series] echo '\_SB_.PCI0.P0P2.PEGP._OFF' > /proc/acpi/call cat /proc/acpi/call 0x1 echo '\_SB_.PCI0.P0P2.PEGP._STA' > /proc/acpi/call cat /proc/acpi/call 0x0 -> I assume that means that the card is disabled (buggy acpi on this laptop didn't give rate information so it's difficult to be sure) lspci |grep VGA 00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 02) 01:00.0 VGA compatible controller: ATI Technologies Inc Manhattan [Mobility Radeon HD 5000 Series] (rev ff) -> difference before the disable, confirmation that it's disabled ? (I assumed so...but when I passed this command at first I thought that there wiil be no ATI line....) echo '\_SB_.PCI0.P0P2.PEGP._ON' > /proc/acpi/call cat /proc/acpi/call 0x1603103c echo '\_SB_.PCI0.P0P2.PEGP._STA' > /proc/acpi/call cat /proc/acpi/call 0xf -> same status as before first disable good point (I think) lspci |grep VGA 00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 02) 01:00.0 VGA compatible controller: ATI Technologies Inc Manhattan [Mobility Radeon HD 5000 Series] -> the same as before tests so good thing BUT : if i try to switch on ATI, black screen with blinking "_".... Someone have an idea about what I made wrong ? last thing that I do not understand, why vga_switcheroo speaks about "VGA switcheroo: detected switching method \_SB_.PCI0.GFX0.ATPX handle" I didn't find anything in SSDT/DSDT about this.... Can I assume that vga_switcheroo do not work on my laptop (even if it thinks that it works...) ? Last thing : ls /proc/acpi/video/ GFX0 PEGP I assume that PEPG is the ATI card and GFX0 the integrated one. Am I wrong ? Sorry for all this question, but If someone can help me, I'll thank him a lot !!!!!
