Changing bootloader resolution and grey apple screen.
« on: April 23, 2011, 06:51:22 AM »
First I edited the boot.plist file in the /extra folder to include my native resolution 1366x768x32 but the bootloader looks the same. Then I found Lizard and the themepark section so I downloaded a theme with the same resolution and put it in the theme folder. Lizard reads the correct resolution under both basics and theme tabs. Also checked the boot.plist and the background image on full screen is the correct resolution but when I reboot I still get a low res boot screen. Get the same thing when using 1080 resolution theme on an external 1080 monitor. I think it might be the graphics card it has nvidia 420m 1gb optimus card (and yes it works full res on both internal and external once osx loads). Maybe it needs to load the card drivers before full res? Or do themes go full resolution before the system loads no matter the card? Also how can I get rid of that apple grey screen the only guides I found date from 01-06 so pretty useless. I saw a chameleon page that said next bootloader would support this and even has a picture but can't find how to anywhere.

Hello nullr1,

First, this really belongs in the questions sub-forum. =).

Second, there's sort of 2 parts to getting native res during the boot process. First there's within Cham UI, then there's the apple grey loading screen. For the latter, setting it in boot.plist is the way to do it, whether you do it using Lizard app or manually. To set the resolution within the Cham UI, well it depends on the version of Chameleon. If you have a very early version of RC5 or RC4 or less, you'll want to set it within the plist of the theme folder itself. For newer RC5 builds, you don't have to do anything, as it reads the resolution from the same apple.boot.plist from above.
Example entry:

For BOTH of these to work, the graphics card itself needs to support the resolution you want as a VESA standard. This is independent of the OS and does not use any card specific drivers. If it doesn't support the res via VESA then neither will work at all. This may be what is happening here. Have you tried going into graphics info within ChamUI options? Does it list the resolution you want there? If that doesn't get you started on the problem, then you may want to check out:

Regarding the apple grey screen, I'm not sure I understand, you want to get rid of the entire loading section of the bootup process? If you mean the color of the background, then no, you cannot change it, at least not technically. Cham allows you to change the apple icon it uses, you could swap out that image, with an image that is the entire size of the screen resolution, allowing you to have what ever background you'd like. The image is boot.png within the theme folder.
