update on my progress.

 

i try to edit ATI4600Controllers with this hex

 

02 00 00 00 40 00 00 00 09 01 00 00 01 02 00 05 (LVDS)

10 00 00 00 10 00 00 00 00 01 00 00 10 10 01 06 (VGA)

00 08 00 00 00 02 00 00 00 01 00 00 20 00 02 01 (HDMI)

 

and use Shrike as the framebuffer. the result is there's an output on LVDS but it's corrupted.

Hi guys!

 

I've been installing Lion 10.7.2 on my Dell 1645 with ATI Mobility 4670 today and have some success.

 

I've managed to get it working but with output only via the HDMI port.

 

Not managed to get anything on the LVDS/laptop screen yet, i did try jvilla's lids connector info by modifying the next as per this post:

 

http://www.insanelymac.com/forum/index.php?showtopic=249642

 

I boot with GraphicsEnabler=Yes and AtiConfig=Flicker, If i use Shrike or Gliff then it panics on boot up.

 

Can someone send me their connector info and/or working 4600 kext?

I have had a stroke of luck using Shrike running 10.7.2 with ATY_Init. Been trying to get HDMI output but when it does output on HDMI I loose LVDS. Confusing.

 

Anyway if anyone wants to try shrike on LVDS this is what I used:

 

02 00 00 00 40 00 00 00 09 01 00 00 00 01 00 05 (LVDS)

Hi!

 

Thanks for registering and sharing matty.

 

Can you tell us what bootloader you are using and also share the rest of the contents of your /Extra folder, specifically any configuration files?

 

Thanks, looking forward to testing this out.

 

Thanks,

I'm just using the latest Chimera bootloader with GraphicsEnabler=No and an iMac11,2 system definition (although changing this seems to make no difference). No special contents, just a basic set up. Hope all goes well :)

Thanks matty! I just tried it and as I speak I'm typing this using the LVDS display on my Dell 1645 for the first time!

 

Awesome. Really appreciate you taking the time to post this matey.

This is what i settled on:

 

0000000 0200 0000 4000 0000 0901 0000 0001 0305 LVDS

0000010 1000 0000 1000 0000 0001 0000 0010 0206 VGA from GLIFF (As that worked before in previous testing)

0000020 0008 0000 0400 0000 0001 0000 1001 0101 HDMI

 

VGA + LVDS + HDMI all work fine, but you need cables in at boot time for VGA and HDMI.

VGA + LVDS = OK (if cables plugged in before laptop turned on)

HDMI + LVDS = OK (if cables plugged in before laptop turned on)

plugging in HDMI cable disables LVDS (if booted up without cable)

clicking 'Detect Displays' disables LVDS

 

I tried about 17 different combinations of encoder/transmitter values and could never stop LVDS disabling when HDMI cable was plugged in except when i changed the 'Features' settings of the HDMI entry (used 0x09) but then LVDS stayed on and HDMI continually tried to sync (garbage output)

 

I found that I could never get LVDS without ATY_Init, so that must have been what I was doing wrong before.

 

I should also mention that I'm able to get full resolution on the laptop display (1920x1080) and external monitor (1920x1200) at the same time.

I'm glad it worked for you. I have just been messing around with your set up and i believe I have fixed HDMI + LVDS (plugging cables in after boot). Not sure about vga, i have no monitor to check it with but i added yours anyway.

 

02 00 00 00 40 00 00 00 09 00 00 00 00 01 00 05 (lvds)

00 08 00 00 04 02 00 00 00 01 00 00 10 01 01 01 (hdmi)

10 00 00 00 10 00 00 00 00 01 00 00 00 10 02 06 (vga)

 

If you want to test it let me know how it goes :)

Hi Matty, thanks again! Yes i can boot without an HDMI cable attached now and when i plug it in the LVDS stays on and the HDMI monitor comes on and displays a picture! Nice!

 

However, booting without a VGA cable connected and then clicking 'detect displays' results in it detecting the monitor (name appears, etc) but no output on monitor. But at least the LVDS does not turn off when you click 'Detect displays' now. Very nice.

 

I'll poke that extra byte after the features byte and set it to 0 for vga to see if that helps. Did you find out the meaning of that byte or was it just a guess?

 

Also, are you using a DSDT file, and do you have sleep/audio/bt/lan/wifi working? I only have BT and wifi working (though I use a different wifi card that the one that came with the machine)

After grabbing my old VGA monitor out of the garage I think the LVDS+VGA (plugged in before boot) is now working again. Don't know what that byte was for really, just a guess.

 

02 00 00 00 40 00 00 00 09 00 00 00 00 01 00 05 (LVDS)

00 08 00 00 04 02 00 00 00 01 00 00 10 01 01 01 (HDMI)

10 00 00 00 10 00 00 00 00 00 00 00 00 10 02 06 (VGA)

 

Yes I am using a basic DSDT file, still trying to get sleep going, VoodooHDA for audio (tried this but i couldn't get it to work http://www.insanelymac.com/forum/index.php...32495&st=80 ).

BT with DellBluetoothHCI.1.2.pkg, Lan with BCM5722D.kext and working wifi (I also use a different wifi card, but I have had the Dell Wireless 1397 that came with my system working too). Battery icon working. And touchpad working with basic gestures + keyboard

I'm not too sure how different are systems may be because I believe you said you had the 1645 and I have the 1647. I have attached the kexts I use.

Thanks matty.

 

Cool that your VGA is working too, would be nice if it would work after boot but not the end of the world, hardly ever use that port anyway...

 

I've also got sound and BT working here, no sleep, not tried battery yet but will take a look at your dsdt file and the kexts you uploaded and report back when i've had the chance to test them.

 

Cheers!

Hello all, Hydrasworld, thanks for the info and your help. I've finally got my 1645 LVDS working after months of trying. Really appreciate all the hard work the people on this board and insanelymac have put in. One question Hydrasworld, did you ever get LVDS working on the 1645 on Snow Leopard? Do you think its possible?

 

Best wishes docdune

I didn't get LVDS working on 10.6.x, back then I didn't know about the connectorinfo hex editing. I *did* get output on my displayport monitor though, will full QE/CI on 10.6.something, 10.6.4 i think. Still works fine on 10.7.2 so I'm happy.

 

Glad you got LVDS working too! Please keep the thread updated with other hardware/drivers and things that you get working.
