You can try setting `i915.enable_psr=0` at boot (the "add i915.enable_psr=0 into your kernel boot parameters" part of the comment I linked to and posted) or set the enable_psr parameter on the i915 kernel module.

The Fedora docs cover setting module parameters.[1] This is how setting the kernel module parameter manifests on my system:

    $ sudo grep -iR i915.enable_psr /etc/modprobe.d
    /etc/modprobe.d/i915.conf:options i915 enable_psr=0

    $ sudo cat /etc/modprobe.d/i915.conf 
    options i915 enable_psr=0

Assuming you use the default GRUB 2 boot loader, the Fedora docs also cover setting the kernel boot parameters.[2]

I'm not sure why it doesn't have an effect on my system. When I add the i915.conf to /etc/modprobe.d/ and reboot my system the PSR is still active:

    [root@fwk ~]# cat /etc/modprobe.d/i915.conf
    options i915 enable_psr=0
    [root@fwk ~]# cat /sys/kernel/debug/dri/1/i915_edp_psr_status
    Sink support: yes [0x03]
    PSR mode: PSR2 enabled
    Source PSR ctl: enabled [0x80000226]
    Source PSR status: SLEEP [0x30000114]
    Busy frontbuffer bits: 0x00000000
    Frame: PSR2 SU blocks:
    0 0
    1 0
    2 0
    3 0
    4 0
    5 0
    6 0
    7 0

It also has no effect when I append i915.enable_psr=0 to GRUB_CMDLINE_LINUX in /etc/default/grub and reboot.

Mine's confirmed disabled, so I'm stumped:

    $ sudo cat /sys/kernel/debug/dri/1/i915_edp_psr_status
    Sink support: yes [0x03]
    PSR mode: disabled
    PSR sink not reliable: no

I'd raise a proper support request[1] with Framework then, who are generally more responsive and thorough with these kinds of problems than most laptop tech support (they put me down this path to start with).

May I ask you what security features you have enabled? Mine looks like this:

    [root@fwk ~]# fwupdmgr security

     fwupd plugins:                 Untainted

I was wondering whether maybe one of those (maybe the kernel lockdown) prevents me from switching the PSR mode?
