Hi Alberto on my machine NVIDIA Optimus setup is no working even with the latest version of "ubuntu-drivers-common" i.e.:(1:0.2.91.8), although it does work with older version of this package i.e. (1:0.2.91.4). I have noticed one difference in the xorg.config file generated by the new and old versions of gpu-manager. Basically when using NVIDIA GPU as the main one i.e. "prime-select nvidia" the old gpu- manager sets the "Driver" value for the "intel" device to "modesetting", but the new gpu-manager sets the "Driver" value for the "intel" device to "intel".
As far as I can understand by looking into the X server log setting the "Driver" value to "intel" instead of "modesetting" prevents the X server from correctly identifying the screen on my laptop giving a black screen on boot. Please see the file attached to this post for a comparison of xorg.conf files generated by the new and old gpu-managers. ** Attachment added: "Comparison of the xorg.conf files generated by the new(not working) and old(working) gpu-managers" https://bugs.launchpad.net/ubuntu/+source/ubuntu-drivers-common/+bug/1310489/+attachment/4308885/+files/gpu-manager_xorg.conf_files_comparison -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1310489 Title: xorg.conf overwritten by booting system To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-drivers-common/+bug/1310489/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
