<pre><span class="quote">>Just to check: When you boot with nomodeset, does any screen work?</span >
No, none of the external screens work. I had to login and run intel_reg_dumper
without seeing anything. Note that while the notebook is on the dock, the lid
is closed. The dock has a power button...
<span class="quote">>Also, does the BIOS manage to light anything up properly? At what point do you
>start to see the black screen (linux or boot-loader/grub or ...)?</span >
No nothing before the Kernel powers up any of the screens. Nor the bios, nor
grub. Without nomodeset on 3.14, I can see text messages of services starting
on VGA.
<span class="quote">>Can you try to remove any special options from grub like gfxmode or similar and
>let grub run in legacy vga mode?</span >
Current configuration:
linux /boot/vmlinuz-3.14.0-rc8+
root=UUID=135a331c-88e4-4131-8630-93fc16045d95 ro rd.md=0 rd.lvm=0 rd.dm=0
vconsole.keymap=us rd.luks=0 vconsole.font=latarcyrheb-sun16 quiet
What should I try?</pre>
