    Question Acer Travelmate 2420 blue screen upon boot (iDeneb 1.3)

    Hello all,
    I have recently installed iDeneb 1.3 upon my Acer Travelmate 2420. I figured that it would work (SSE2, 2GB RAM, 40GB HDD, 1.7GHz centrino). The install goes fine, I've selected the ICHx fix, StageXNU kernel, and the AC'97 audio driver. When I boot the system, i get the grey apple logo with the spinny thing, then the screen turns light blue, and then completely freezes. There is no cursor on the screen, I cannot toggle caps lock on and off (my test to see if anything is working), I cannot adjust screen brightness nor can I disable the touchpad or kill the backlight (which all can be done prior to the apple logo disappearing).

    I am able to boot the system successfully into single user mode, but not into safe mode or with the -f boot option.

    Any help would be greatly appreciated.
    Chris

    Well, I've done that, but no errors. I've got the same damn blue boot screen. I installed the OS on my other computer to see what it should do, and upon first boot it had a grey background. The most I get out of it on boot is some hard drive activity and then nothing. Most of the time it freezes right after the apple logo disappears.

    It took a few tries and a couple hours of googling, but yes, it turned out to be the drivers. Thank you muchly for the tip-off

    Well, assuming your computer is using the Intel GMA900 graphics set, Leo4All has a link on the main page to the place to get the graphics drivers I'm using. It can be a bit tricky to get them installed, so here's what I did (starting from install):

    1. Formatted drive HFS+ Non Journaled (IMPORTANT FOR NEXT STEPS AS KNOPPIX CANNOT WRITE TO A JOURNALED PARTITION)
    2. Made sure no GMA950 .kexts were checked.
    3. Waited for system to install
    4. Checked to see if there was any graphics output (if there is skip to step 15 or 16)
    5. Booted with no graphics output (just a blue screen) with the welcome tune playing
    6. Powered off the system, booted my Knoppix Live Linux DVD (available at this link.)
    7. Mounted the hda2 partition, enabled write access (right click, change read/write mode)
    8. Opened Konsole, typed in
    Code:
    sudo konqueror
    9. Typed in the address bar /media/hda2/System/Library/Extensions/
    10. Minimized Konqueror, opened IceWeasel, went to Leo4All, and clicked the download link at the bottom of the large post about the GMA900.
    11. *NOTE* This step required multiple tries for me. Seems that writing to HFS+ with Knoppix is temperamental. If it refuses to write, reboot and try again. It's best to save the downloaded files to a flash drive as if you have to reboot, all changes are lost! *END NOTE* Unzipped the two .kexts to the desktop, and dragged them into the Konqueror window we opened in step 9.
    12. If they wrote successfully (prompted for overwrite of AppleIntelIntegratedFramebuffer.kext), reboot. If unsuccessful, reboot and go back to step 6.
    13. Boot OS X with the -s boot option.
    14. Run the following commands
    Code:
    /sbin/fsck -fy
    /sbin/mount -uw /
    cd /System/Library/
    chmod -R 755 Extensions/
    chown -R root:wheel Extensions/
    touch /System/Library/Extensions
    reboot
    15. Your computer should now boot successfully, with full QE/CI (Quartz Extreme and Core Image) support!
    16 (Optional). Open Disk Utility (In /Applications/Utilities) and enable Journaling.
    This whole process took me about a day to figure out. If everything goes according to plans, it should take about an hour (after install). There are some slight mouse artifacts, but they in no way make the system harder to use.

    If there was graphics output and you are not just installing updated drivers, then you do NOT and SHOULD NOT follow this tutorial. This is only for if you have a GMA900 card.
    I am not responsible for any damage you do because of these steps. They worked for me, and the worst you can do is install unnecessary .kexts which may or may not cause your system to hang on boot. If you do manage to screw it up this way, PM me and I'll address your issues.
