I've decided to report the issue here since it seems to be a kernel bug, and since Mint is based on Ubuntu where its kernels are built, I thought it'd be wise to report here and escalating to the LKML if necessary. Firstly, its display turns off when it boots, unless an external display is connected, in which case both displays work fine. But the backlight can't be controlled by typical programs (brightness buttons don't work, and xbacklight says 'No outputs have backlight property') apart from light (https://github.com/haikarainen/light); but that only works on kernels 5.15.*, not on 6.3.4, on that kernel only the brightness value changes, but to no effect. Upon bootup, I can see: uhci_hcd 0000:00:1a.0: Found HC with no IRQ. Check BIOS/PCI 0000:00:1a.0 setup! uhci_hcd 0000:00:1a.0: init 0000:00:1a.0 fail, -19 uhci_hcd 0000:00:1d.0: Found HC with no IRQ. Check BIOS/PCI 0000:00:1d.0 setup! uhci_hcd 0000:00:1d.0: init 0000:00:1d.0 fail, -19 at the top of the screen for a few seconds before the Mint splash screen takes over. The device's internal display turns off upon wake up from suspend, giving the following output in dmesg: PM: suspend entry (deep) Filesystems sync: 0.020 seconds Freezing user space processes ...

What I mean is the "icon" for it doesn't exist anymore, but moving the mouse around I can see some buttons display their shadows indicating that the mouse is above them and clicking the buttons works. Using SWcursor in Xorg "fixes" this issue, but the mouse becomes flickery and this is obviously a sub-optimal hack. I can consistently get the system to freeze by opening some specific websites in Firefox: any video on yewtu.be or youtube.com, amazon.co.uk and discord.com/app after some usage. It seems the thing they have in common is some sort of video playback, although autoplay is off, but the system freezes immediately once it finishes (and sometimes before it even does finish) loading the website. What's even more strange is that local video works, using mpv for example, and Blink based apps don't seem to suffer as much. Almost no freezes happen with Chromium and Freetube (which is Blink-based afaik), but the system does occasionaly freeze for several seconds, and then the internal display turns off, but is still "functional" in the sense that windows are still rendered on it and I can drag windows back and forth from it, but it is completely black, when using these apps. This happens incosistently and randomly, though. I have some errors for this experience after using Discord for a few minutes on chromium: radeon 0000:01:00.0: ring 0 stalled for more than 10248msec radeon 0000:01:00.0: GPU lockup (current fence id 0x000000000000c9f0 last fence id 0x000000000000caa2 on ring 0) radeon 0000:01:00.0: failed to get a new IB (-35) radeon 0000:01:00.0: failed to get a new IB (-35) [drm:radeon_cs_ib_fill [radeon]] *ERROR* Failed to get ib !

Identical artifacts seemed to appear in the exact same place on the exact same characters wherever those characters appeared. I've attached a few photos showing this. I've also noticed this in dmesg when the artifacts appeared: kauditd_printk_skb: 16 callbacks suppressed Not sure if it is related or not, but I've included this info just in case. All the logs and bugs have been observed on linux 5.15.0-72, but I've also installed 6.3.4-060304 from the Ubuntu mainline kernel PPA recently and observe similar/same bugs, and since this is quite an old code path, I doubt it has changed much, but I can try and recreate them again with the new kernel version if needed. --- ProblemType: Bug ApportVersion: 2.20.11-0ubuntu82.5 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: hashim 1083 F.... pulseaudio /dev/snd/controlC1: hashim 1083 F.... pulseaudio CasperMD5CheckResult: unknown CurrentDesktop: XFCE DistroRelease: Linux Mint 21.1 InstallationDate: Installed on 2023-05-28 (2 days ago) InstallationMedia: Linux Mint 21.1 "Vera" - Release amd64 20221217 MachineType: Apple Inc. iMac11,2 NonfreeKernelModules: zfs zunicode zavl icp zcommon znvpair Package: linux (not installed) ProcFB: 0 radeondrmfb ProcKernelCmdLine: root=UUID=1b8dcf89-8d16-46e1-a89d-8d9b8fd71bc2 ro quiet splash initrd=boot\initrd.img-5.15.0-72-generic ProcVersionSignature: Ubuntu 5.15.0-72.79-generic 5.15.98 RelatedPackageVersions: linux-restricted-modules-5.15.0-72-generic N/A linux-backports-modules-5.15.0-72-generic N/A linux-firmware 20220329.git681281e4-0ubuntu3.13 Tags: vera Uname: Linux 5.15.0-72-generic x86_64 UnreportableReason: This report is about a package that is not installed.
