HN second-chance bump just had to happen when I had a power outage... Back up now :)

GNU started with frustration over a cursed printer and a cursed proprietary driver for it. 2026, we are still dealing with this kinda thing.

This is why I have to run 2 GPUs on my work laptop. My 6 monitors are split 3/3 between the iGPU and the dGPU. Except the drivers are all trash so any time a monitor connects or disconnects there's about a 90% chance the displays stop updating and forces either a reboot or a restart of something up the software chain. What would be really nice is to find a way to keep my programs running some restarting the GPU drivers, which Windows can often do. I'll also note that I haven't had success with just more physical adapters. The drivers complain they can't create a CRTC for them.

Or get monitors that support daisy chaining (https://www.dell.com/support/contents/en-us/article/product-support/self-support-knowledgebase/monitor-screen-video/guide-daisy-chain-monitors https://www.dell.com/support/contents/en-us/article/product-...). P.S. There seems to be a list of monitors at https://www.jdhodges.com/blog/displayport-mst-lcd-list/ https://www.jdhodges.com/blog/displayport-mst-lcd-list/

  There's a hard limit of 4 displays on Nvidia, even if they're chained via MST - that is how I have a couple of them already. I don't have the PCI-e slots for a second GPU
