OK, from what I've read this does work, but requires specific configuration |
| 9 |
in the kernel, in the xorg.conf and the target (DE) desktop environment to |
| 10 |
work. Also there are several ways to achieve this multi-head system and the |
| 11 |
final outcome is sometimes constrained by a variety of factors. No |
| 12 |
doubt this will be a "project" for you. |

Exact specification of the video cards, your DE, and which method you |
| 17 |
choose will be needed to google for specific examples and receive help |
| 18 |
from others. |

Yes, let's start with gentoo's page on this: [1] |
| 24 |
|
| 25 |
Here are some additional links that, once you read them, you'll have |
| 26 |
a basis and resources to cut snippets into a highly customized xorg.conf |
| 27 |
file. [2] |
| 28 |
|
| 29 |
Also, do you want one big virtual screen across the (2) monitors, |
| 30 |
or do you want them to display form different applications? Also |
| 31 |
do you want a second keyboard and mouse so it can also be used |
| 32 |
like a second workstation at times? I saw a few sites that talk |
| 33 |
about how to switch between modes. So define exactly what you want |
| 34 |
to do and verbosely list your hardware. Then google for specific |
| 35 |
code snippets and cobble together your xorg.conf. Then we can |
| 36 |
hack away at that, based on any additional features that your |
| 37 |
chosend (DE) provides (features or management of hardware). |
| 38 |

Last, folks are raving about multihead monitor support with LXQT |
| 40 |
which used QT5, but that all seems to be very news. |
| 41 |
|
| 42 |
Once you figure this out, give some feedback to the gentoo docs |
| 43 |
team to enhance [1]. BGO would be keen for new information |
| 44 |
on multi headed options. |
