Only black screen on the external monitor with intel-virtual-output

Hello,

I tried to install bumblebee on my Lenovo W520 with this tutorial:
http://www.unixreich.com/blog/2013/linu … ly-solved/

I can activate my external monitor with "intel-virtual-output" and the monitor is switching on. But I can only see a black screen.
In the settings of gnome I can see my external monitor and configure it - but it shows nothing.

Have you any ideas?

Thanks a lot!

Re: Only black screen on the external monitor with intel-virtual-output

Hi karol,

the downgrade of xf86-video-intel fixed my problem nearly.

After booting and typing "modprobe bbswitch && optirun true && intel-virtual-output", my Gnome Shell crashes.
If I now login again, I can activate my external monitor with "intel-virtual-output".

Any ideas to activate the monitor without crashing the gnome shell?

Thank you!

Re: Only black screen on the external monitor with intel-virtual-output

Hi,

Same problem here on my Lenovo W530.
Intel-virtual-output used to work fine but since it got upgraded the virtual output stays black.

I tried downgrading the xf86-video-intel package but there is a dependency conflict.

Available packages:

   1) xf86-video-intel-2.99.916-3-x86_64.pkg.tar.xz (local)
   2) xf86-video-intel-2.99.916-3-x86_64.pkg.tar.xz (remote)

Why don't you use 'downgrade glamor-egl' too?

Re: Only black screen on the external monitor with intel-virtual-output

Sorry, I forgot to mention that I already tried to downgrade it.
But glamor-egl somehow conflicts with xorg-server so pacman wants to remove xorg during the downgrade.
And I don't really feel comfortable by downgrading or removing xorg. :-)

Why not? There are unofficial repos that have xorg15 and older: https://wiki.archlinux.org/index.php/Ca … positories

Re: Only black screen on the external monitor with intel-virtual-output

I think that I am having a similar problem on a ThinkPad W530 ( details in thread https://bbs.archlinux.org/viewtopic.php?id=192298 ), did you thwfreak find a solution? How could I debug what is broken to try to get it working with the later versions as well?
