My rocket lake CPU (i11900k) on a Z590 Asus motherboard will only boot dual monitors on 5.10.0-1023-oem. Kernels below that will boot a single monitor (display port) if I enable i915.force_probe=NNNN. Kernels above 5.10 such as 5.11, 5.12 and several other variants including some of the nightlies and drm-intel-next will NOT boot. They hang on boot at "fb0: switching to inteldrmfb from EFI VGA"
I am a bit of a newbie but let me know how I can help. If you need logs tell me how to get the ie what command. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1905466 Title: drm/i915: Drop force_probe requirement for Rocket Lake Status in linux package in Ubuntu: Triaged Status in linux-oem-5.10 package in Ubuntu: Invalid Status in linux source package in Focal: Invalid Status in linux-oem-5.10 source package in Focal: Fix Released Status in linux source package in Hirsute: Triaged Status in linux-oem-5.10 source package in Hirsute: Invalid Bug description: [Impact] drm/i915 currently requires using i915.force_probe=NNNN to load the driver on RKL, but we should drop the requirement from this kernel so that machines being tested don't need to work around it locally. [Test case] Enable in the kernel, boot it on RKL, see that graphics use the native driver. [What could go wrong] Only affects RKL, so it's possible that RKL hw that would fail to boot with the native driver would regress, compared to fallback driver. But we've had this enabled for oem-5.10 since the start, and there are no RKL related fixes not already found in 5.11, so it should be safe to enable.
