Gentoo - DisplayLinkManager crash

Hi lspintzyk,

Thanks for your quick reply.

Although lsmod shows the evdi module as loaded, there is no evdi device appearing:

Code:

# ls -la /sys/devices/evdi
ls: cannot access '/sys/devices/evdi': No such file or directory

So this is probably related to why I'm not seeing any evdi logging in dmesg.

I'll play around with getting the module to work and let you know how I make out.

It turns out my aggressive CFLAGS were causing the module to not work properly. If I can narrow down which ones are the culprit then I'll open an issue at the evdi repo.

Thanks again!

Turns out the module fails to initialise when compiled with LTO
