Public bug reported: Hi, I have a problem after a kernel update on ubuntu 24.04 arm64. In a few words up to kernel 6.8.11 everything works well and I can change the screen resolution. Starting from kernel 6.8.31 (linux-generic), I cannot do it anymore. I tried manually installing several kernels (for instance 6.8.4-060804-generic) and even linux-generic-hwe (6.11.x). I did many tests by changing the configuration and following the advice of the mate community https://ubuntu-mate.community/t/ubuntu-mate-24-04-screen-resolution-fixed-to-1024x768-with-last-kernel-update/. However, I came to the conclusions that is something related with ubuntu (gnome or mate is indifferent). Indeed, I tried with: Debian 12.11 with kernel 6.1.x and mate desktop: no problem (expected). Debian 13 daily build with kernel 6.12.x and mate desktop: no problem. Fedora 42 workstation with kernel 6.14.x and gnome desktop: no problem. Ubuntu 24.04 server with kernel 6.8.x and 6.11.x: problem (works only up to kernel 6.8.11). Ubuntu 25.04 with kernel 6.14.x and gnome desktop: problem.
I have to mention that my device SoC, Qualcomm Snapdragon 8cx gen 2, is the only one in the series (gen 1, gen 3 and gen 4 https://bugzilla.kernel.org/show_bug.cgi?id=218512) that is not supported by the linux kernel. So the only solution I have found to use my device is to use hyper-v on windows 11 (virtualbox does not work on arm on windows https://www.virtualbox.org/manual/topics/Introduction.html#host-guest- matrix).
