morkb Posted April 25, 2011 Share Posted April 25, 2011 Hi all, I have a hp notebook with hybrid graphic card, one is intel hd 4500 if i remember well and the other is ati mobility 5470 I cannot switch off the intel graphic from bios no option at all (if I read well it's because GPU is integrated in CPU) I have a dsdt.aml that Mald0n kindly made me My question is....is there a way to switch off integrated intel graphic card or make it seen as secondary card instead of primary through dsdt.aml? As there are some kind of drivers for ati but there is no drivers at all for intel and SL is limited to 1024 x 768 and obviously no hardware acceleration Many thanks Marco Link to comment Share on other sites More sharing options...

morkb Posted June 9, 2011 Author Share Posted June 9, 2011 ..yes I found on linux some method.. look at these..from a linux website Please keep providing DSDT.dsl information in this bug report: This is the list of calls to turn off the switchable graphics card in Linux so far: \_SB.PCI0.P0P1.VGA._OFF \_SB_.PCI0.OVGA.ATPX \_SB_.PCI0.OVGA.XTPX \_SB.PCI0.P0P2.PEGP._OFF \_SB.PCI0.MXR0.MXM0._OFF \_SB.PCI0.PEG1.GFX0._OFF \_SB.PCI0.PEG1.GFX0.DOFF \_SB.PCI0.XVR0.Z01I.DGOF \_SB.PCI0.PEGR.GFX0._OFF If you haven't tried the switchable graphics feature in Linux yet, have a look at your DSDT.dsl file. With a bit of luck, you may be able to identify one of the methods above. i tried \_SB.PCI0.PEG1.GFX0._OFF \_SB.PCI0.PEG1.GFX0.DOFF in my dsdt..but didn't work...anyway I'm not an expert in dsdt..so probably I made 99% for sure an error bye Marco Link to comment Share on other sites More sharing options...
bluegeek Posted December 20, 2011 Share Posted December 20, 2011 Hello, Any advances on this? I also want to disable the integrated graphics using the DSDT. Thanks. Link to comment Share on other sites More sharing options...

bluegeek Posted August 27, 2012 Share Posted August 27, 2012 In my HP G72 there's a BIOS tool to disable Hybrid/Switchable Graphics. Link to comment Share on other sites More sharing options...
