glitches and not working linux apps

[michal800106]

Hello I have problems with running linux applications on freebsd. I have build system (world and kernel) from drm-next branch.

And for example I have weird glitches in skype4 login window.

And I'm not able to login. I'm not a fan of skype app, but my company uses it and I want to use Freebsd as my main system - in work too.

I have loaded modules as below:

# kldstat

My graphic card:

vgapci0@pci0:1:0:0:     class=0x030000 card=0x84461043 chip=0x11c610de rev=0xa1 hdr=0x00
    vendor     = 'NVIDIA Corporation'
    device     = 'GK106 [GeForce GTX 650 Ti]'
    class      = display
    subclass   = VGA

In dmesg I see some errors:

As of freebsd/freebsd-ports@690be662c5ee this repo is out of date compared to graphics/drm-next-kmod which has #166 fixed. For non-graphical issues better report via bugzilla where you can CC emulation@ if it's related to running Linux apps.

net-im/skype4 was probably "retired" on 2017-07-01 by Microsoft while the new Electron-based client (similar to Chrome) still doesn't work due to missing Linux syscalls. Maybe @xmj knows more.

It's also worth noting that the user is reporting an issue with an Nvidia GPU which isn't part of the work that the drm-next branch is focused on. Closing out this issue as it does not apply to the code in the repo.
