First of all, good work in getting this far! I'm currently trying to get my 5650 to work properly on my Sony Vaio VPC-EC3M1E.
What I did so far:
- Installed OSX Retail 10.6.3 using Nawcom's boot-CD (0.3.1)
- Combo-updated to 10.6.7
- Before reboot, installed the necessary kexts from Lion
- Replaced my boot file with the one from the first post
- Installed Chameleon RC5 r748 (with Kabyl support) using #####
- Installed SwitchResX and created a custom resolution of 1600x900 (native resolution for my LVDS)
If I boot with GraphicsEnabler=yes, I have native resolutions and full QE/CI on my HDMI output (1920x1080) and my external monitor (1280x1024). Unfortunately, the internal LVDS remains black.
Under System Profile, my card is correctly shown as an ATI 5000.
Based on the above posts, I tried to get my LVDS to work as well using different framebuffers. So far, I've tried Eulemur, Hoolock, Vervet, Baboon, Langur, Nomascus and Madison. All result in either a black LVDS or one with a weird-looking 'white cloud'. Booting goes fine though, since I can always VNC into the operating system. In all cases, available resolutions are 1024x768, 1280x1024 and 1680x1050. For some reason, the custom resolution in SwitchResX doesn't show up anymore. Also, if I check my video card under System Profile it shows 'ffff...' etcetera.
Can anyone point me in the right direction here? Any help would be much appreciated!
EDIT: Played around a bit more and made some progress. I extracted my screen's EDID based on a guide elsewhere and edited the DisplayProductID-717 file. If I boot in verbose mode, my card is identified as a 5650 Nomascus. Unfortunately, using Nomascus as a framebuffer doesn't work (leads to a deadbeef error).
Using Hoolock leads to my external monitor being identified as main, with nothing on the laptop screen. The closest I got was using Baboon as a framebuffer. It correctly identified my external monitor as an extended desktop, but the laptop screen still shows white lines, blocks, etcetera. I was able to VNC into OSX though and noted that all the correct resolutions are shown! Yet if I change them, the screen just flickers a bit.
The native resolution of my laptop screen is 1600x900. I read that maybe another solution is required for screens larger than 1440x900? Anyhow, hope someone can help me out!
