@Jerry Kao This is standard Ubuntu 14.04.05 LTS. For some reason the Nvidia driver doesn't create the egl group for my computer, for example:
$ update-alternatives --config x86_64-linux-gnu_egl_conf There are 2 choices for the alternative x86_64-linux-gnu_egl_conf (providing /etc/ld.so.conf.d/x86_64-linux-gnu_EGL.conf). Selection Path Priority Status ------------------------------------------------------------ * 0 /usr/lib/x86_64-linux-gnu/mesa-egl/ld.so.conf 500 auto mode 1 /usr/lib/x86_64-linux-gnu/libhybris-egl/ld.so.conf 400 manual mode 2 /usr/lib/x86_64-linux-gnu/mesa-egl/ld.so.conf 500 manual mode However the gl group is normal: $ update-alternatives --config x86_64-linux-gnu_gl_conf There are 3 choices for the alternative x86_64-linux-gnu_gl_conf (providing /etc/ld.so.conf.d/x86_64-linux-gnu_GL.conf). Selection Path Priority Status ------------------------------------------------------------ 0 /usr/lib/nvidia-370/ld.so.conf 8604 auto mode * 1 /usr/lib/nvidia-370-prime/ld.so.conf 8603 manual mode 2 /usr/lib/nvidia-370/ld.so.conf 8604 manual mode 3 /usr/lib/x86_64-linux-gnu/mesa/ld.so.conf 500 manual mode That's why this update broke my Optimus and I am stuck in Intel mode. Like I said it's a Nvidia Quadro K3100M system which is not quite common. Could that be related? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1642662 Title: SRU request: handle EGL alternatives and use different drivers for the LTS stacks To manage notifications about this bug go to: https://bugs.launchpad.net/hwe-next/+bug/1642662/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
