Nouveau/ru

nouveau — это открытый драйвер для графических карт NVIDIA.

Ограничения
Being an open source project running on what is largely proprietary hardware, there are some limitations inherent to Nouveau that are not applicable to the closed-source nvidia-drivers. That said, Nouveau is constantly evolving, so these limitations are subject to change over time.

Udev
If NVIDIA's proprietary driver has been installed, it will have installed a udev rules file in. When attempting to use the nouveau driver without disabling that rule file, the X11 log file fill up with a block of messages like this repeating every 10ms:

To prevent this (without uninstalling the package), simply remove/move/rename the udev file  so that is no longer taken up by udev (see Advanced Configuration of udev). Note that the next time nvidia-drivers is updated, that file will be re-installed, so consider unmerging nvidia-drivers.

xorg.conf
X server разработан для работы «из коробки», поэтому нет необходимости вручную редактировать файлы настройки. Сервер сам должен определить и настроить устройства - мониторы, клавиатуры и мыши.

However, the main configuration file of the X server is the file.

Ограничения
Some of the current issues or draw-backs compared to the closed-source are stated below:


 * Performance (especially 3D performance) on the same card/chipset may be significantly worse than using nvidia-drivers.
 * Attempts to run at higher refresh rates (i.e. above 60 Hz) may fail.
 * Using advanced features from various NVIDIA cards (e.g. multiple-display capabilities of Quadro cards without SLI) may not function correctly.

Проблемы встречающиеся при использовании нескольких мониторов
When the screen freezes often with possible EDID probes while using dual monitors/displays, try adding  or   (enable or disable respectively) to the  or  command line options, substituting the name of the monitor listed within  or. (ie. CRT-1, VGA-1, LVDS-1, DVI-1, ...)

For instance, on a Dell Inspiron 8100 laptop with a connected external display connected via the laptop's external VGA port, a possible command line is:. The EDID (DRM) probe on the external VGA connected display is still causing freezing during nouveau/drm load for the author, but at least it's usable if the display is connected after grub is loaded and prior to the nouveau/drm modules loading. And with the prior mentioned command line LVDS/VGA resolutions, the displays are cloned and centred with somewhat correct resolutions for cloned displays.

NVIDIA Optimus
When using a laptop with NVIDIA's Optimus technology (usually found in laptops built in 2010 and later), everything will be passed through the integrated graphics controller (usually Intel) before it gets to the discreet video card (NVIDIA), which can cause a lot of otherwise unexplained problems when enabled. There are a few ways to handle this, but the simplest is to disable Optimus through the BIOS (normally accessed by pressing during boot). This will result in increased power consumption (decreased battery life, increased running temperature), as the NVIDIA card will now be handling all of the work all of the time.
