For #44 Aaron's suggested patch, it seems patch have been included after 4.15.0-46. The testing 18.04.2 iso with 4.15.0-48 kernel seems the system would be hang on language selection after select install server of grub screen. So it seems this hibmc_drm would caused another this hang issues too. This hibmc_drm driver can only work for ARM64, as I know, chip vendors don't have any intend/interesting to make this drm/kernel driver to work for x86.

@Aaron Ma I want to test your patch. But seems it would patch with error. I guess, the new 18.04 source code have been change to: list_add_tail(>list, _list); instead of: - list_add(>list, _list); + list_add_tail(>list, _list); Does it mean this patch have been already merged in our new source.

summary for workaround via kernel parameter to blocker loading: modprobe.blacklist=hibmc_drm **prevent load during install To add "modprobe.blacklist=hibmc_drm" kernel parameter in grub when boot from d-i iso (press ‘e’ key and then press F10 or ctrl+x ( those key was noticed on the screen).

[Kernel-packages] [Bug 1762940] Re: Ubuntu 18.04 d-i install screen becomes blurry on Huawei server in EFI boot mode
Dann, For the wanland issues, I understood it as comments in #15, that is: Blur screen for GDM login was caused by wayland, it can be fix by force to use Xorg in /etc/gdm3/customer.conf to uncoment WaylandEnable=false Is this right for your wanland issues on D05? In 18.04, we found 2 issues on Huawei X86 server. One is screen blur during d-i install on UEFI model in Language selection screen, but it works for legacy bios model. The other is after start GUI (x-window or Ubuntu desktop). After we sucessfully installed 18.04 in legacy bios model on X86 Huawei server, I tried to start X-windows via apt-get install ubuntu-dekstop and reboot, we would get this blur screen again. This seems caused by this wanyland and can be fixed by this "WaylandEnable=false". As I know, this wayland issues have been happened for D05 but I don't think D05 have above issues during install. -- 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/1762940 Title: Ubuntu 18.04 d-i install screen becomes blurry on Huawei server in EFI boot mode Status in linux package in Ubuntu: Triaged Status in linux source package in Bionic: Triaged Bug description: For all(as I know) Huawei servers, the vga adapter are embed in the iBMC chips.

[Kernel-packages] [Bug 1762940] Re: Ubuntu 18.04 d-i install screen becomes blurry on Huawei server in EFI boot mode
This looks to me as if Ubuntu (the kernel, Wayland, and/or the X server, depending on when the problem occurs) is delivering a video mode that the display device can't handle. (With VGA, the display should deliver its capabilities to the computer via EDID, but this doesn't always work correctly.) Thus, the first question is what that "display device" is. The screen shots look like a remote KVM of some sort. Is that the BMC's built-in screen-sharing tool, a network-accessible KVM hardware device (like a Raritan or Avocent), or something else? If possible, I recommend testing in person with a plain monitor plugged directly into the computer, at least as a diagnostic procedure. If that works, then it's likely that the issue is either a matter of a restrictive set of video modes in the remote-access tool, miscommunication between the remote- access tool and the kernel/Wayland/X, or both. Also, if a physical monitor is plugged into the server while it's being accessed remotely, it's conceivable that the kernel/Wayland/X is taking its cues about video mode from the physical monitor rather than from the remote-access tool, thus creating a mismatch. If the problem is caused by the remote access tool, or by an interaction between that and the kernel/Wayland/X, then updating the remote access tool's firmware may fix the problem. Note that the video mode used can vary depending on the kernel version, X vs. Wayland, EFI vs. BIOS boot mode, and other factors. Such variables likely explain why earlier kernels worked but newer ones don't. As a workaround, it might be possibly to forcibly reconfigure the system to use a video mode that will work with the display device. Unfortunately, there are a lot of different ways to do this, depending on the subsystem involved. For instance: * Kernel parameters can set the kernel's video mode. Unfortunately, there are a lot of possibilities even here, including, but not limited to: * nomodeset * video=vga16fb:off * vga16fb.modeset=0 * video=efifb:width:640,height:480 * Try Googling "kernel video mode setting" or something similar for additional possibilities. * X configuration * If you can get X working, even temporarily, you can use the GUI setup tools to change the resolution. * The xrandr tool can be used to probe and set video options; see https://www.x.org/wiki/Projects/XRandR/ * I've not kept up with text-mode (manual) X configuration, but you may be able to find some documentation on how to get it to change video mode. Start here: https://help.ubuntu.com/community/VideoDriverHowto#Xorg.conf.d * Wayland configuration * I'm even less of an expert on this, so I suggest you try Googling "wayland set resolution" or something similar. Finally, note that Ubuntu server certification doesn't cover display devices, so this is NOT a certification blocker. -- 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/1762940 Title: Ubuntu 18.04 d-i install screen becomes blurry on Huawei server in EFI boot mode Status in linux package in Ubuntu: Triaged Status in install-package source package in Bionic: New Status in linux source package in Bionic: Triaged Bug description: For all(as I know) Huawei servers, the vga adapter are embed in the iBMC chips.
