 crushing-smite | I mean, if there is a GPU involved, otherwise, it's just a vnc client | 10:46:35 |
| crushing-smite | * I mean, if there is a GPU involved, regardless of, it's just a vnc client | 10:46:44 |
| crushing-smite | as if I was streaming over the net | 10:47:04 |
 K900 | No, if you pass through a GPU, you'll get no output on SPICE | 10:47:08 |
| crushing-smite | so, a defficiency of a protocol | 10:47:10 |
| K900 | You'll only get output on the monitor connected to the GPU | 10:47:26 |
| crushing-smite | how did people get image from gpu passthrough in the days before looking glass? | 10:48:05 |
| K900 | Because SPICE only works with the virtualized QEMU GPU | 10:48:09 |

how did people get image from gpu passthrough in the days before looking glass? They switched the input on their monitor | 10:48:17 |
| crushing-smite | so, directly plugged? | 10:48:25 |
| K900 | You still need to have the monitor plugged into the GPU | 10:48:46 |
| K900 | Even with Looking Glass | 10:48:49 |
| K900 | Because it needs to be rendering somewhere | 10:48:57 |
| crushing-smite | should have sucked back then | 10:48:55 |
| crushing-smite | oh, really? | 10:49:03 |
| K900 | Yes | 10:49:08 |
| crushing-smite | Can I have a virtualized dummy? | 10:49:15 |
| K900 | No | 10:49:18 |
| K900 | The GPU is physical | 10:49:23 |
| K900 | So you can't connect virtualized things to it | 10:49:29 |
| crushing-smite | So, I really need a second monitor to use looking glass? | 10:49:31 |
| K900 | You can buy a dummy HDMI plug off Aliexpress or something | 10:49:38 |

So, I really need a second monitor to use looking glass? No, you can connect both GPUs to the same monitor | 10:49:46 |
| K900 | If it has multiple inputs | 10:49:50 |
| K900 | And then just use the input from the host GPU | 10:49:56 |
| crushing-smite | Then looking glass is not accessing the GPU memory, it is accessing the actual physical screen's buffer? | 10:49:58 |
| K900 | The actual physical screen's buffer is in the GPU memory | 10:50:09 |
| crushing-smite | but not exactly acccessible until there's a physical plug, right? | 10:50:27 |
 @atemu12:matrix.org | crushing-smite: It's recording the physical screen and passing that recording through shared memory AFAIUI | 10:50:43 |
| K900 | It doesn't exist until there's a physical plug because the GPU doesn't see any displays connected to it | 10:50:46 |
