I installed 4.15.0-56-generic to a bionic VM, with the -modules and -modules-extra packages. I went into /var/lib/modules/4.15.0-56/ and did a search for hibmc_drm. There was no mention apart from a header Makefile. The module was not built and not present on amd64.
I did the same for 5.0.0-22-generic in a disco VM, and the module was not built and was not present. 4.15.0-56-generic has been installed to a amd64 based Huawei server which was having the issues explained in this bug, and since the module was not present, the screen was not "blurry" when a desktop environment was installed and viewed from the remote access tool used by Huawei. To ensure that ARM64 still has the kernel module built, I also downloaded linux-modules-extra for 4.15.0-56-generic for ARM64. The hibmc_drm module is still present in /var/lib/modules/4.15.0-56/kernel/drivers/gpu/drm/hisilicon/hibmc This means that Huawei's arm64 based servers will not be affected by the change. The fixes solve the problems of the video mode not being right for amd64 based platforms, and does not cause any regressions for ARM64. I am happy to mark this as verified. ** Tags removed: verification-needed-bionic verification-needed-disco ** Tags added: verification-done-bionic verification-done-disco -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1762940 Title: hibmc-drm Causes Unreadable Display for Huawei amd64 Servers To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1762940/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
