Android emulator freeze my whole system when it can't connect to adb daemon

Issue

I recently changed my computer and took the opportunity to move from Mageia to Fedora. But I can't do any Android development anymore because, as stated in the title, starting any AVD makes the whole system to freeze (screen, mouse and keybord) if the AVD can't connect to adb daemon. The only thing I can do is hard shutdown.

The problem here is adb daemon is always started when I try to launch an AVD as the service is enabled by default, so that shouldn't happen.

What I've been able to collect so far is a few logs in a file by lauching the emulator from command-line. All it says before freezing is:

emulator: INFO: GrpcServices.cpp:301: Started GRPC server at 127.0.0.1:8554, security: Local
emulator: ERROR: AdbHostServer.cpp:102: Unable to connect to adb daemon on port: 5037

But, if I manually restart the adb service just before lauching the AVD, I don't experience the freeze. Instead, I get the following errors before the AVD crashes:

cannot add library .../android-sdk-linux/emulator/qemu/linux-x86_64/lib64/vulkan/libvulkan.so: failed
added library .../android-sdk-linux/emulator/lib64/vulkan/libvulkan.so
cannot add library .../android-sdk-linux/emulator/lib64/vulkan/libvulkan.so.1: full

My best guess here is there's something bad going on with the graphic card. Something I am seemingly the only one to exprerience as I couldn't find any relevant result on internet. I must mention here that I've already tried to run several AVDs in multiple API versions, both software and hardware rendered graphics and I always get the same result.

My system configuration is

• AMD Ryzen 9
• Nvidia GeForce RTX 2070 using the Nouveau drivers
• kernel 5.11.

Solution

If anyone ever stumbles upon this question facing the same issue than me, that was solved by getting rid of the Nouveau drivers and using Nvidia's proprietary drivers. A handful of other disturbing bugs on my computer were solved by doing just that.

I really don't understand why some Linux distribution still strongly advise to use the Nouveau drivers over Nvidia'as when they have a such a really poor support of the GPUs...
