Public bug reported: [Impact] Intel TGP dekstop cannot detect second monitor.
[Fix] Remove an IRQ setup routine and re-order some other IRQ setups. [Test] 1. Boot up the system with single monitor connected. 2. Hotplug second monitor. With the fix applied, the system can detect the 2nd monitor correctly. [Where problems could occur] This fix removed some special handling for early gen Core, so HPD on those old Core systems might be affected. ** Affects: hwe-next Importance: Undecided Status: New ** Affects: linux-oem-5.10 (Ubuntu) Importance: Undecided Status: Invalid ** Affects: linux-oem-5.10 (Ubuntu Focal) Importance: Medium Status: Confirmed ** Tags: oem-priority originate-from-1933585 stella ** Also affects: linux-oem-5.10 (Ubuntu Focal) Importance: Undecided Status: New ** Changed in: linux-oem-5.10 (Ubuntu) Status: New => Invalid ** Changed in: linux-oem-5.10 (Ubuntu Focal) Status: New => Confirmed ** Changed in: linux-oem-5.10 (Ubuntu Focal) Importance: Undecided => Medium ** Tags added: oem-priority originate-from-1933585 stella -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-oem-5.10 in Ubuntu. https://bugs.launchpad.net/bugs/1935853 Title: Fix second monitor hotplug on Intel TGP PCH Status in HWE Next: New Status in linux-oem-5.10 package in Ubuntu: Invalid Status in linux-oem-5.10 source package in Focal: Confirmed Bug description: [Impact] Intel TGP dekstop cannot detect second monitor.
