Describe the bug
drmModeGetResources failed when start, it error in 11.0.0 Preview 2, but work in 0.10.18

To Reproduce

public static void Main(string[] args) => BuildAvaloniaApp()
            .StartLinuxDrm(args, scaling: 1);

Expected behavior

I am getting this same issue as well

System: Radxa model rock 3
Mali g52

Operating system: Debian bullseye

Kmscube is running fine

[AndreSteenbergen]

Maybe this helps. This is the output from kmscube

[AndreSteenbergen]

Could this be a problem for us as well?
ardera/flutter-pi#13

when I look into /dev/dri/* I see card0, card1, renderD128 and renderD129

[AndreSteenbergen]

I get a different error now when I specify the card to use. I don't have an ssh connection to the SBC. But when specifying /dev/dri/card0 I get a EGL_BAD_MATCH error.

at CreateWindowSurface. Maybe that helps

Is a picture of my screen

The card search order got changed by #7749

I think it is now somewhat random since it enumerates cards in filesystem order.

We should probably rewrite our code to scan cards in numeric order and to pick the first one that actually works instead of the first one we can get a file descriptor for.

As a workaround, pass the correct card to the card parameter of StartLinuxDrm

[AndreSteenbergen]

I did I get the above error now: EGL_BAD_MATCH now. I am debugging why I am getting that particular error

[AndreSteenbergen]

        using (var x = new DrmCard(Card))
        {
            try
            {
                var y = x.GetResources(true);
                y.Dump();
            }
            catch 
            {
            }
        }

Now gives:

    Connector
        DSI-1
            Id: 154
            Size: 217, 136 mm

            Modes
                800x480

work in 11.0.999-cibuild0033386-beta when set card0

I'm use Lubancat 2, RK3568

[mghcool]

I have the same problem

[mghcool]

我使用的是 Lubancat 2、RK3568

你目前解决这个问题了吗？能不能说明一下我也用的鲁班猫2

[Coloryr]

这边建议你换板子，鲁班猫2的固件bug很多
然后渲染不用GPU的，巨卡
你去dev/dri看看card有那些
我去年看只有card0是工作的

那rk3568用drm效果如何？

走GPU的话就很好

[mghcool]

我找到问题了，是因为使用gbm_surface_create是输入的图像格式不对，应该从XR24改为AR24

将
Avalonia.LinuxFramebuffer.Output.LibDrm.GbmColorFormats.GBM_FORMAT_XRGB8888 { get; } = FourCC('X', 'R', '2', '4');
改为
Avalonia.LinuxFramebuffer.Output.LibDrm.GbmColorFormats.GBM_FORMAT_XRGB8888 { get; } = FourCC('A', 'R', '2', '4');

这样就可以正常运行。
我使用ildasm将Avalonia.LinuxFramebuffer.dll反编译成il文件，修改上述位置后再用ilasm将修改的il打包成dll文件，将原来程序的替换掉就可以正常运行了

[Coloryr]

我用rk3566的orangepi 3B没这问题，估计还是lubancat的驱动问题
