The output looks correct in both versions. There's the driver and it creates a console. So it's got to be in the driver logic. There have been several changes recently in how such output to BMCs are handled. Under /sys/class/drm/, there should be 2 directories called card1-VGA-1 and card1-Vritual-1, right? Can you please provide the output of cat /sys/class/drm/card1-VGA-1/status cat /sys/class/drm/card1-VGA-1/modes cat /sys/class/drm/card1-Virtual-1/status cat /sys/class/drm/card1-Virtual-1/modes ? Is it possible for you to run the very latest kernel v6.12-rc1 on the machine? -- You are receiving this mail because: You are on the CC list for the bug.

From: 6.11.0-1-default, where the BMC VGA shows no output:

``` localhost:~ # ls /sys/class/drm/ card0 card0-VGA-1 card0-Virtual-1 version localhost:~ # cat /sys/class/drm/card0-VGA-1/status disconnected localhost:~ # cat /sys/class/drm/card0-VGA-1/modes

There's no monitor attached, so this is correct.

localhost:~ # cat /sys/class/drm/card0-Virtual-1/status connected localhost:~ # cat /sys/class/drm/card0-Virtual-1/modes 1920x1440 1856x1392 1792x1344 1920x1200 1920x1200 1600x1200 1680x1050 1680x1050 1400x1050 1400x1050 1600x900 1280x1024 1440x900 1440x900 1280x960 1360x768 1280x800 1280x800 1280x768 1280x768 1024x768 800x600 800x600 848x480 640x480

Hence the BMC is marked as connected. So this output is also correct. Do you know if the BMC supports such high resolutions? I could imagine that the console picks one of the high-res modes and the BMC cannot handle it.

localhost:~ # ```

From an older 6.10.5 that I happened to have on that system:

``` localhost:~ # uname -ra Linux localhost 6.10.5-1-default #1 SMP PREEMPT_DYNAMIC Fri Aug 16 11:15:41 UTC 2024 (30fd964) x86_64 x86_64 x86_64 GNU/Linux localhost:~ # ls /sys/class/drm/ card0/ card0-VGA-1/ localhost:~ # cat /sys/class/drm/card0-VGA-1/status connected localhost:~ # cat /sys/class/drm/card0-VGA-1/modes 1024x768 800x600 800x600 848x480 640x480

This is also correct. Before 6.11, there was no virtual connector and only XGA was supported by default.

```

I'll try to grab 6.12, will take a little longer to build it.

Great. v6.12 will again do away with the virtual connector for the BMC and handle it internally in the VGA. But it will be implemented differently and provide more resolutions. -- You are receiving this mail because: You are on the CC list for the bug.
