update-alternatives #888

Open gdkrmr opened 7 years ago

gdkrmr commented 7 years ago

on Ubuntu 16.04, bumblebee testing and nvidia 3.75:

when choosing the nvidia gl driver from update-alternatives --config x86_64-linux-gnu_gl_conf, gdm gets stuck in a start-crash loop at startup, when choosing the mesa driver cuda applications do not work:

$ optirun ./simpleAssert 
simpleAssert starting...
OS_System_Type.release = 4.4.0-83-generic
OS Info: <#106-Ubuntu SMP Mon Jun 26 17:54:43 UTC 2017>

CUDA error at ../../common/inc/helper_cuda.h:1133 code=30(cudaErrorUnknown) "cudaGetDeviceCount(&device_count)"

Please report this to the nvidia-375 Ubuntu maintainers: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-375

I thought this was a bumblebee issue, reported it anyways to launchpad. CUDA applications crash with error code 999 if I configure the update-alternatives to the mesa driver, but then I get the boot loop if I forget to reconfigure before a reboot.

Also see here: https://github.com/JuliaGPU/CUDAdrv.jl/issues/50

I reported this here, because it started appearing after the last update of bumblebee (3/7/17, bumblebee and bumblebee-nvidia, each 3.2.1-100~xenialppa1 over 3.2.1-98~xenialppa1) from the ubuntu testing ppa (http://ppa.launchpad.net/bumblebee/testing/ubuntu). The last nvidia update was on 1/6/17.

There were only tiny changes, as the blacklist/dependency alternatives for new driver series (378, 381, 384) was added between those 2 versions. Nothing else changed.

You can see the commits here: https://github.com/Bumblebee-Project/bumblebee-ppa/commits/master

Given you are running 375, those changes do not affect your setup in any way.

that is strange, it is probably some issue with my configuration then.
