Hi,

I notice a regression report on Bugzilla [1]. Quoting from it:

Hello I have been having problems for some time now with displaying any linux distribution with the new kernal. The only thing that can fix it are older kernals.

I can't describe it very well, so I'm attaching some pictures, but it's like whenever anything happens on the screen, it pushes the upper left half up from the bottom. But it only goes to a certain extent, after that it just shakes around and jumps back a bit. Also, for example, the firefox icon is not where it is displayed, but where it should be (I tried it with touch).

I think it has something to do with the framebuffer, because an usb stick with just the arch iso show the same issue in the tty.

The hardware is a Huawei Matebook E 2022. Cpu: Intel® Core™ i5-1130G7 Graphics: Intel® Iris® Xe

Example under Manjaro that worked was with the linux-lqx-6.1.0.lqx2-1-x86_64.pkg.tar.zst kernal 22-Dec-2022 14:44 154507169 from https://repo.blacksky3.com/x86_64/linux-lqx/old/

Kernals above that Version dosent work, Example with 6.1.1-lqx1-linux-lqx: ` $inxi -F System: Host: Johannes Kernel: 6.1.1-lqx1-linux-lqx arch: x86_64 bits: 64 Desktop: GNOME v: 43.5 Distro: Manjaro Linux Machine: Type: Detachable System: HUAWEI product: DRC-WXX v: M1010 serial: Mobo: HUAWEI model: DRC-WXX-PCB v: M1010 serial: UEFI: HUAWEI v: 1.30 date: 06/29/2022 Battery: ID-1: BAT1 charge: 27.8 Wh (66.0%) condition: 42.1/42.1 Wh (100.0%) volts: 11.9 min: 11.5 CPU: Info: quad core model: 11th Gen Intel Core i5-1130G7 bits: 64 type: MT MCP cache: L2: 5 MiB Speed (MHz): avg: 1395 min/max: 400/1801 cores: 1: 897 2: 1046 3: 962 4: 1801 5: 1801 6: 1801 7: 1801 8: 1052 Graphics: Device-1: Intel Tiger Lake-UP4 GT2 [Iris Xe Graphics] driver: i915 v: kernel Display: wayland server: X.org v: 1.21.1.8 with: Xwayland v: 23.1.1 compositor: gnome-shell driver: gpu: i915 resolution: 2560x1600~60Hz API: OpenGL v: 4.6 Mesa 23.0.3 renderer: Mesa Intel Xe Graphics (TGL GT2) Audio: Device-1: Intel driver: N/A Device-2: Intel Tiger Lake-LP Smart Sound Audio driver: sof-audio-pci-intel-tgl API: ALSA v: k6.1.1-lqx1-linux-lqx status: kernel-api Server-1: PulseAudio v: 16.1 status: active Network: Device-1: Intel Wi-Fi 6 AX201 driver: iwlwifi IF: wlp0s20f3 state: up mac: f4:b3:01:b7:c6:6d Bluetooth: Device-1: Intel AX201 Bluetooth driver: btusb type: USB Report: rfkill ID: hci0 state: up address: see --recommends Drives: Local Storage: total: 476.94 GiB used: 9.65 GiB (2.0%) ID-1: /dev/nvme0n1 model: PCIe-8 SSD 512GB size: 476.94 GiB Partition: ID-1: / size: 468.09 GiB used: 9.65 GiB (2.1%) fs: ext4 dev: /dev/nvme0n1p2 ID-2: /boot/efi size: 299.4 MiB used: 288 KiB (0.1%) fs: vfat dev: /dev/nvme0n1p1 Swap: Alert: No swap data was found.

`

Distros I testet: Ubuntu 20.04.2 results in Blackscreen/poweroff Fedora 38 (Bug as I mentiond) Manjaro (Bug as I mentiond) It all works fine when you start from grub2 in Rescue mode.

That all is very new to me, so I am sorry if I did something wrong. I mean, I reported that bug first at the wrong place.. Anyway

Best regreds Johannes

See Bugzilla for the full thread and attached pictures that demonstrate this regression.

Anyway, I'm adding it to regzbot:

#regzbot introduced: v6.1..v6.4 https://bugzilla.kernel.org/show_bug.cgi?id=217666 #regzbot title: screen shakes on Intel® Iris® Xe

(also Cc'ing stable list because it also occurs on v6.1.y, but not in v6.1 mainline).

Thanks.
