I'm running efl-1.19.0 and e-0.21.7 under Debian unstable. Since upgrading the Linux kernel from latest 4.10 to 4.11 I cannot run "su" under X any more. "su" on console works perfectly though.
su: Authentication failure
~$ sudo ls
sudo: effective uid is not 0, is /usr/bin/sudo on a file system with the 'nosuid' option set or an NFS file system without root privileges?
Also, the Cpufreq module cannot set the cpu power state setting.
This issue has already been reported on e-users mailing list and has also been discussed on a gentoo forum without a solution: https://forums.gentoo.org/viewtopic-p-8064594.html
I'd be happy to help debug this issue or provide more information about my system.
