Rainey Posted November 25, 2011 Share Posted November 25, 2011 I installed Lion, ran EDP 2.2 and all was good, didn't use sleep enabler as i know it caused issues with the 10.7.2 update. Installed 10.7.2 and now when i boot i have a black screen, i have read this is due to the DSDT, i have inserted the fix below BUT how can i perform this or resolve my issue from eiter -s on boot OR using the terminal in install mode OR running a linux live cd. Thanks for you advise Black Screen FIX (DSDT Injection): Replace: QUOTE "device_type" Buffer (0x0D) { "NVDA,Geforce" } with: QUOTE "device_type" Buffer (0x0C) { "NVDA,Parent" } Link to comment Share on other sites More sharing options...
arzolacub Posted December 13, 2011 Share Posted December 13, 2011 That fixis the problem indeed. You need to make the editting with a dsdt editor such as DSDTSE. That happens only with D830, not with other models like d630... This SHOULD be included in next edp version, I think. greetinds Link to comment Share on other sites More sharing options...

pud469 Posted February 18, 2012 Share Posted February 18, 2012 I had the same issue. I took a different approach. At first I though it was an EDID issue. I tried putting the EDID into the DSDT, but it didn't work. There were many possible reasons why this didn't work. So I tried with a vanilla DSDT and had no trouble getting to a desktop, but without graphics acceleration. Tried with graphics enabler and it worked great, it also listed the card as a Quadro NVS 140M 256 MB, without having to enter the specific information into the DSDT. As there were a few other issues without the other DSDT modifications, I chose to use the modified DSDT from here and restore the video section back to the original with "graphicsenabler=yes" in the org.chameleon.boot.plist. Everything works great and the system profiler has the actual video card information listed per the injection of chameleon. I attached my modified DSDT, just remember to use graphics enabler.

alticavis Posted March 7, 2012 Share Posted March 7, 2012 I am curious. I have this black screen issue swell, but only intermittently. I can shut down, and restart, and most times it start working again. Will this fix work in my case aswell?? Link to comment Share on other sites More sharing options...
jeremynuss Posted March 7, 2012 Share Posted March 7, 2012 I've also experienced this issue. I found that it occurs after my laptop has been put to sleep, and after installing menutab for facebook. No other apps so far. . . If I put a -f switch at boot the system will load. Link to comment Share on other sites More sharing options...
