I tried updating the amdgpu firmwares from the linux-firmware package from git.kernel.org. This didn't help. The display is still garbled after it returns from power-save of the display (not the computer suspending).
Firmware versions on linux 6.8.0-50 before my upgrade (and kernel upgrade); VCE feature version: 0, firmware version: 0x00000000 UVD feature version: 0, firmware version: 0x00000000 MC feature version: 0, firmware version: 0x00000000 ME feature version: 35, firmware version: 0x00000027 PFP feature version: 35, firmware version: 0x0000002f CE feature version: 0, firmware version: 0x00000000 RLC feature version: 1, firmware version: 0x0000007f RLC SRLC feature version: 0, firmware version: 0x00000000 RLC SRLG feature version: 0, firmware version: 0x00000000 RLC SRLS feature version: 0, firmware version: 0x00000000 RLCP feature version: 1, firmware version: 0x0000000f RLCV feature version: 0, firmware version: 0x00000000 MEC feature version: 35, firmware version: 0x00000023 IMU feature version: 0, firmware version: 0x0b012900 SOS feature version: 0, firmware version: 0x00000000 ASD feature version: 553648327, firmware version: 0x210000c7 TA XGMI feature version: 0x00000000, firmware version: 0x00000000 TA RAS feature version: 0x00000000, firmware version: 0x00000000 TA HDCP feature version: 0x00000000, firmware version: 0x1700003c TA DTM feature version: 0x00000000, firmware version: 0x12000016 TA RAP feature version: 0x00000000, firmware version: 0x00000000 TA SECUREDISPLAY feature version: 0x00000000, firmware version: 0x00000000 SMC feature version: 0, program: 0, firmware version: 0x004c4100 (76.65.0) SDMA0 feature version: 60, firmware version: 0x00000010 VCN feature version: 0, firmware version: 0x07113000 DMCU feature version: 0, firmware version: 0x00000000 DMCUB feature version: 0, firmware version: 0x08003700 TOC feature version: 0, firmware version: 0x0000000b MES_KIQ feature version: 6, firmware version: 0x00000073 MES feature version: 1, firmware version: 0x00000052 VPE feature version: 0, firmware version: 0x00000000 VBIOS version: 113-PHXGENERIC-001 firmware versions after me replacing the firmwares in /lib/firmware/amdgpu with the ones from https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux- firmware.git/ and kernel upgrade to 6.8.0-51 ; VCE feature version: 0, firmware version: 0x00000000 UVD feature version: 0, firmware version: 0x00000000 MC feature version: 0, firmware version: 0x00000000 ME feature version: 35, firmware version: 0x00000028 PFP feature version: 35, firmware version: 0x00000030 CE feature version: 0, firmware version: 0x00000000 RLC feature version: 1, firmware version: 0x00000080 RLC SRLC feature version: 0, firmware version: 0x00000000 RLC SRLG feature version: 0, firmware version: 0x00000000 RLC SRLS feature version: 0, firmware version: 0x00000000 RLCP feature version: 1, firmware version: 0x0000000f RLCV feature version: 0, firmware version: 0x00000000 MEC feature version: 35, firmware version: 0x00000028 IMU feature version: 0, firmware version: 0x0b012900 SOS feature version: 0, firmware version: 0x00000000 ASD feature version: 553648359, firmware version: 0x210000e7 TA XGMI feature version: 0x00000000, firmware version: 0x00000000 TA RAS feature version: 0x00000000, firmware version: 0x00000000 TA HDCP feature version: 0x00000000, firmware version: 0x17000042 TA DTM feature version: 0x00000000, firmware version: 0x12000018 TA RAP feature version: 0x00000000, firmware version: 0x00000000 TA SECUREDISPLAY feature version: 0x00000000, firmware version: 0x00000000 SMC feature version: 0, program: 0, firmware version: 0x004c4100 (76.65.0) SDMA0 feature version: 60, firmware version: 0x00000015 VCN feature version: 0, firmware version: 0x0911600c DMCU feature version: 0, firmware version: 0x00000000 DMCUB feature version: 0, firmware version: 0x08004800 TOC feature version: 0, firmware version: 0x0000000b MES_KIQ feature version: 6, firmware version: 0x00000073 MES feature version: 1, firmware version: 0x0000006e VPE feature version: 0, firmware version: 0x00000000 VBIOS version: 113-PHXGENERIC-001 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2091205 Title: Screen garbled after screen returns from suspend To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-amdgpu/+bug/2091205/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
