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). 1: https://framework.kustomer.help/contact/support-request-ryon9uAuq https://framework.kustomer.help/contact/support-request-ryon...

May I ask you what security features you have enabled? Mine looks like this: [root@fwk ~]# fwupdmgr security Host Security ID: HSI:3 (v1.8.10) HSI-1 CSME manufacturing mode: Locked CSME override: Locked CSME v0:16.0.15.1810: Valid MEI key manifest: Valid Platform debugging: Disabled SPI BIOS region: Locked SPI lock: Enabled SPI write: Disabled Supported CPU: Valid TPM empty PCRs: Valid TPM v2.0: Found UEFI platform key: Valid UEFI secure boot: Enabled HSI-2 IOMMU: Enabled Intel BootGuard: Enabled Intel BootGuard ACM protected: Valid Intel BootGuard OTP fuse: Valid Intel BootGuard verified boot: Valid Platform debugging: Locked TPM PCR0 reconstruction: Valid HSI-3 Intel BootGuard error policy: Valid Intel CET Enabled: Enabled Pre-boot DMA protection: Enabled Suspend-to-idle: Enabled Suspend-to-ram: Disabled HSI-4 Intel SMAP: Enabled Encrypted RAM: Disabled Runtime Suffix -! Intel CET Active: Supported Linux kernel: Untainted Linux kernel lockdown: Enabled Linux swap: Encrypted fwupd plugins: Untainted I was wondering whether maybe one of those (maybe the kernel lockdown) prevents me from switching the PSR mode?
