I just hit the issue again, and in i915_display_info, the cursor is reported as visible, but it's not showing on screen: CRTC 47: pipe: A, active=yes, (size=1920x1080), dither=no, bpp=24 fb: 118, pos: 0x0, size: 1920x1080 encoder 106: type: DP-MST A, connectors: connector 117: type: DP-3, status: connected, mode: "1920x1080": 60 148500 1920 2008 2052 2200 1080 1084 1089 1125 0x48 0x5 cursor visible? yes, position (334, 6), size 256x256, addr 0x00880000 num_scalers=2, scaler_users=0 scaler_id=-1, scalers[0]: use=no, mode=10000000, scalers[1]: use=no, mode=0 --Plane id 30: type=PRI, crtc_pos= 0x 0, crtc_size=1920x1080, src_pos=0.0000x0.0000, src_size=1920.0000x1080.0000, format=XR24 little-endian (0x34325258), rotation=0 (0x00000001) --Plane id 37: type=OVL, crtc_pos= 0x 0, crtc_size= 0x 0, src_pos=0.0000x0.0000, src_size=0.0000x0.0000, format=N/A, rotation=0 (0x00000001) --Plane id 44: type=CUR, crtc_pos= 334x 6, crtc_size= 256x 256, src_pos=0.0000x0.0000, src_size=256.0000x256.0000, format=AR24 little-endian (0x34325241), rotation=0 (0x00000001) underrun reporting: cpu=yes pch=yes When it's showing, the cursor part of the above text is identical, apart form the 'addr' (including the plane with id 44). The intel_reg command just printed an error: Error: /usr/share/igt-gpu-tools/registers/gen8_interrupt.txt:1: ('GEN8_MASTER_IRQ', '0x00044200', '') Error: /usr/share/igt-gpu-tools/registers/skylake:1: gen8_interrupt.txt Error: /usr/share/igt-gpu-tools/registers/kabylake:2: skylake Warning: reading '/usr/share/igt-gpu-tools/registers/kabylake' failed. Using builtin register spec. but then printed some registers. Attaching for when it's visible, and invisible. Attaching dump --all too for good measure.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are on the CC list for the bug.</li> <li>You are the assignee for the bug.</li> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
