I am on 64 bit but I imagine that 32 bit should be the same:

Code: Select all

root@porteus:~# uname -r
3.17.4-porteus
Maybe you should try fanthom's advice. He usually very rarely miss the bull's eye.

For the kernel compilation here is the howto:

That's simply hillarious.
Asking which kernel has Porteus when it was explicitly mentioned in my post before that it is porteus-3.17.4.
Recommending to check fanthom's solution, which requires modesetting when OP stated that without "nomodeset" (i.e. with modesetting) his machine boots into black screen.
Asking that maybe it's Nvidia when OP clearly said in his 1st post it is Intel.
Repeating that xrandr thing again.
Bunch of zombies.

Where did you find i915.nomodeset=1 option in my post?

Also, if you will try other kernel mode setting options which I already posted above in the thread, make sure not to use them alongside "nomodeset" or else it loses any sense.

If you don't like edit porteus.cfg file each time you need to try new option, just point selecting cursor in boot menu at boot mode you want, then press TAB to show boot options editing line and type any additional options you want to be used in this session. Then press enter.

No, it's not possible. Therefore guys who provide kernel updates to Porteus do it in vain (http://forum.porteus.org/viewtopic.php?f=75&t=4788), because users contingent which Porteus has is not capable of implementing correct solution even if it is pushed in their face.

Hi
porteus 3.0 has kernel 3.13.6
porteus 3.0.1 has kernel 3.14.15

http://dl.porteus.org/i486/archive/

If e.g. 3.0.1 will work, than you can try 3.1 with this older kernel by
replacing the kernel-module and vmlinuz.

It is rather straight forward if you use the isomaster utility. This link covers my experience with replacing the kernel:

Another option might be this link: http://forum.porteus.org/viewtopic.php? ... 881#p34881

Aye indeed, no idea how that got past me. Also about i915, that was either me doing a typo while posting, or a typo while setting the boot parameter. Either way, i915.modeset=1 unfortunately didn't work either. And I actually edit the boot parameters on the loader, it certainly is easier than editing porteus.cfg when you're just trying things out.

Thanks for that. 3.0.1 booted properly with no black screens. After that I followed Ed's advice and swapped the kernel with that from 3.0.1, and everything booted beautifully!

Thanks everybody for all your help and sticking around. It was definitely frustrating, and I probably became a bother at one point or another, but I'm just glad that Porteus finally works. Case closed!

How come with such tendency it still has no place in FAQ?

@sunny: maybe you should write a howto about searching on the net and on the porteus forum. Yet, in a few posts you seem to have developped some techniques that could be apparented to some superior ninja knowledge.
