| − | - Установите пакеты драйверов NVidia. Для приемлемой производительности установите проприетарные драйвера, подключив источник non-free и запустив настройку через XFDrake.
| + | |
| − | - Добавьте своего пользователя в группу bumblebee (если эта группа не существует,
| + | |
| − | создайте ее и перезапустите демон bumblebeed после этого).
| + | |
| − | - Возможно потребуется войти и выйти из системы, для применения изменений. Перегружаться не нужно.
| + | |
| − | - Приложения теперь можно запускать с префиксом "optirun" для запуска на видеокарте Nvidia. Например так:
| + | |
| − |
| + | |
| − | "optirun glxgears".
| + | |
| − | | + | |
| − | Отличие в работе можно заметить в росте числа кадров по сравнению с нормальным режимом.
| + | |
| − | | + | |
| − | Если это не срабатывает, то:
| + | |
| − | | + | |
| − | * Запустите optirun with the --debug commandline line parameter (as in:
| + | |
| − | "optirun --debug glxgears", for example), and it should provide some
| + | |
| − | meaningful error message as to where the problem is.
| + | |
| − | - If the bumblebeed daemon could not be reached, stop the daemon and
| + | |
| − | manually run it (as root), also with the --debug parameter. It should
| + | |
| − | print a lot of helpful info and error messages. Also make sure you are
| + | |
| − | added to the bumblebee group!
| + | |
| − | - If the GPU could not be started, make sure nvidia drivers are
| + | |
| − | installed properly and power management is working correctly. A reboot
| + | |
| − | might help as well (this restores some internal PCI values that may be
| + | |
| − | corrupted).
| + | |
| − | - If X could not be started, you may have to edit the
| + | |
| − | /etc/bumblebee/xorg.conf.nvidia file. Some errors will also
| + | |
| − | specifically tell you that you need to do this and tell you exactly
| + | |
| − | what to change there.
| + | |
| − | - Still having trouble? Ask for help in #bumblebee on irc.freenode.net
| + | |
| − | | + | |
| − | If after a reboot the whole screen is upside-down and/or garbled:
| + | |
| − | You installed nvidia drivers through some other means than the
| + | |
| − | Mandriva packages - this overwrites the Intel hardware acceleration
| + | |
| − | with non-compatible files. Un-install them and replace by the Mandriva
| + | |
| − | packages. If that doesn't fix the problem, you may have to
| + | |
| − | force-reinstall the Intel drivers and xorg files with urpmi
| + | |
| − | --replacepkgs (do a search for packages containing libGL.so,
| + | |
| − | specifically!). It is possible to use the latest official nvidia
| + | |
| − | drivers as well, but it requires a lot of manual configuration. You
| + | |
| − | need to backup the intel-compatible files and move the nvidia versions
| + | |
| − | to a new directory (for example /usr/lib/nvidia-current), then move
| + | |
| − | the intel files back to their original location. The directory that
| + | |
| − | contains the nvidia-compatible files needs to be put in
| + | |
| − | /etc/bumblebee/bumblebee.conf as well.
| + | |
| − | | + | |
| − | If you want to use nouveau instead:
| + | |
| − | The version of nouveau in Mandriva is not recommended for Optimus
| + | |
| − | configurations, so you may want to manually compile and install a
| + | |
| − | newer version (the more recent, the better). Then change the line
| + | |
| − | "Driver=nvidia" in /etc/bumblebee/bumblebee.conf to "Driver=nouveau".
| + | |
| − | That should be all you need to do. When using nouveau, bbswitch is no
| + | |
| − | longer required for power management and vga_switcheroo can be used
| + | |
| − | instead (enabled by default if bbswitch is not installed), but an
| + | |
| − | extremely recent development version kernel is required for it to work
| + | |
| − | on all models, so this is not advised. Keeping bbswitch installed
| + | |
| − | should allow the nouveau drivers to work with power management on all
| + | |
| − | Optimus model laptops. In the future vga_switcheroo should/will
| + | |
| − | surpass bbswitch in functionality, so the option to use it is there.
