Hey gentoo friends,

I just installed gentoo and I followed the installation guide step by step :)
After the installation was completed, I rebeooted into gentoo and got a green screen :(
I reinstalled everything again... and I get the same error/green-screen again... I really don't know how to fix this.

Here is a little video how it looks like:
https://www.icloud.com/sharedalbum/#B0DJtdOXmJq6m9f

I installed it like the manuale said. I have a x64 computer.
Some configuration I did during the installation:

  • CFLAGS="-march=native -O2 -pipe -mtune=native"
  • MAKEOPTS="-j3"


I installed the kernel as follow:

  • emerge -av gentoo-sources
  • ls -l /usr/src/linux (just for checking)
  • emerge -av genkernel
  • genkernel all


As "tools" i just installed "emerge -av dhcpcd".
Nothing else. So I think my system is pretty clean. Maybe I have to install something elese, too?
But I really don't know how to fix this... help :(

Thank you!! :)

Hi, ChocoFruit. Welcome to Gentoo. :)

The first bad habit you need to unlearn is that, for all practicall purposes, you never need to reinstall: Gentoo is essentially always repairable.

Second, thanks for the video. At the point you are, the console editing keys should be active. Could you scroll back using Shift-PgUp and maybe capture some pictures of the previous few screens. Some things went by so fast at the end of the video that I'm not sure the actual failure symptom is visible.

Finally, from what I saw in the video, I think you're close. ;)

- John

Hey John,

Thank you very much for your quick help :)
I tryed to go up by using Shift-PgUP, but it didn't work. It feels like it is frozen. They keyboard itself works because I can toggle the Num-key. Also Ctr+Alt+Del (for restart) doesn't work. So I have to press the restart button on my pc.
I extracted some photos.
You can watch them here: https://www.icloud.com/sharedalbum/#B0DJtdOXmJq6m9f
To see them in full size, you need to click on them^^
The first photo is the last one before the "green-screen" comes. Then the photos get "earlier"...
So after "Waiting for uevents to be processed..." it somehow failed...
I also googled it. It seems to be that there are many reasons why this can happen.

I have a NVIDIA GTX760, so i found this:
http://superuser.com/questions/802847/nvidia-gtx650-ti-1-gb-nvidia-drivers-boot-udev-fail-on-gentoo
But I didn't installed any other drivers. (Just the one "genkernel all" did)

I think it has something to do with my hardware and drivers... (But I am a noob, so :D )
The thing I don't understand: The installation CD just boots fine. Can't I make a gentoo like on the CD?

Hmm. Looks like from the video that the current kernel may have a problem with its driver support for your video card. We could try installing the nVidia proprietary driver. If you want to do that, chroot into the installed system from the install CD:
  • Reboot into the install CD.
  • Mount your partitions as described in the Handbook under Mounting (only; don't do anything else from that section).
  • Chroot into the installed environment as described in the Handbook under Copy DNS Info through Entering the new environment.
After that, you can install any software you want. In this case, do:
Code:
emerge -va nvidia-drivers
and follow the bouncing ball. After you're done, cleanly exit the chroot by following the handbook at Rebooting the system, remove the installation CD and retry your boot.

By the way, the above gives you a handy tool in your toolbox: how to enter a damaged installation and poke around. ;)

Finally, you are making a Gentoo like the one on the install CD. It's just that kernel and software versions differ depending on when the install CD was built.

- John

Thank you very much! :)
When I did so, after entering "emerge -va nvidia-drivers" I got a lot of missing things and blah... I need some days to work myself through this :)
I hope I can fix it this way...

You should never do this: emerge -va nvidia-driver. The video driver should be pulled in by VIDEO_CARDS variable. In short, if you emerge something to fix your system, always use emerge -1, this way it will not be recorded in the world file.

I solved it now by compiling my own kernel and not using "genkernel all" :)
Today I installed the nvidia driver and kde and everything looks fine until now :)
Thank you very much! :oops:
