All must upgrade! Posted Dec 12, 2025 21:48 UTC (Fri) by alspnost (guest, #2763) [Link] Whoop, first point release for 6.18 LTS - which means it's fully production ready, and the whole world should upgrade to it immediately, right? Actually, I suspect there could be a huge .2 patch coming along, as that's what often happens. Liquorix has released a 6.17.12 build, so they're obviously holding out for 6.18.2 before jumping... Something changed in amdgpu that broke it for me Posted Dec 12, 2025 22:19 UTC (Fri) by dskoll (subscriber, #1630) [Link] (1 responses) I still have video problems, but this time I did create an issue in what I hope is the right place. Something changed in amdgpu that broke it for me Posted Dec 15, 2025 20:19 UTC (Mon) by dskoll (subscriber, #1630) [Link] So, just to close this out... it seems that the amdgpu driver had set an overly-restrictive maximum pixel clock if you used a DisplayPort-to-HDMI passive dongle. As per the issue I'm hopeful this will be fixed in a forthcoming kernel. Anyway, for now I am running a patched kernel and all of my monitors work fine with kernel 6.18.1.
