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 Desktop Packages, which is subscribed to xserver-xorg-video-amdgpu in Ubuntu. https://bugs.launchpad.net/bugs/2091205 Title: Screen garbled after screen returns from suspend Status in xserver-xorg-video-amdgpu package in Ubuntu: New Bug description: When power management turns off the screen, and I wake it I get a garbled screen. There's a divider in the middle and green streaks from the right margin and the middle divider over the garbled background image. I added a picture of the garbled display as an attachment. I am able to login blindly, and removing and inserting the HDMI connector from the computer restores the image. I also have a shellscript that I can activate with a keyboard shortcut that uses xrandr to turn the output off, wait two seconds and turn it on again and that also restores the image. AMD 7840U with built in Radeon 780. I have tried increasing VRAM memory to 2 GB. I tried adding "amdgpu.sg_display=0" to the boot parameters to no avail. What can I do to help debug this problem? I have the same CPU/GPU combo in my T14s laptop, but haven't got the problem there.
