After having a look at drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c in linux-hwe-6.5 version 6.5.0-45.45~22.04.1, I find this line:
status = dc_validate_global_state(dc, dm_state->context, false); As far as I can tell, this is the exact line changed in https://git.kernel.org/stable/c/6266b3a312b7f69c883c2d7c82d85772464421d2 mentioned above, as a fix that might solve this issue. I'll try to build and test a kernel with this fix in place, but am unsure if I will be able to test with an unsigned kernel on the machine in question. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2070096 Title: [amdgpu] Graphics driver issue: Display goes black for a second at random: [drm:link_enc_cfg_validate [amdgpu]] *ERROR* link_enc_cfg_validate: Invalid link encoder assignments - 0x1c To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-oem-6.5/+bug/2070096/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
