Appendix L. Known Issues. OpenGL and dlopen() There are some issues with older versions of the glibc dynamic loader (e.g., the version that shipped with Red Hat Linux 7.2) and applications such as Quake3 and Radiant, that use dlopen(). Please see Chapter 4, Frequently Asked Questions for more details. Multicard, Multimonitor In some cases, the secondary card is not initialized correctly by the NVIDIA kernel module. You can work around this by enabling the XFree86 Int10 module to soft-boot all secondary cards. See Appendix D, X Config Options for details. Interaction with pthreads Single-threaded applications that use dlopen() to load NVIDIA's libGL library, and then use dlopen() to load any other library that is linked against libpthread will crash in libGL. Load the library that is linked with libpthread before loading libGL.Link the application with libpthread. The X86-64 platform (AMD64/EM64T) and 2.6 kernels If you are using a 2.6 x86_64 kernel, it is recommended that you upgrade to a 2.6.11 or later kernel.

Graphing a custom Data Query - www.mad-hacking.net. In the previous section we examined how to create a new Custom Data Query to enable us to query the LM-SENSORS-MIB::lmTempSensorsTable for temperature information. In this section we shall explore how to produce graphs of this information. Creating a new Graph Template Before Cacti can generate a graph for a Data Query it needs to know how that data should be presented. As we discussed in the Basic Cacti Concepts section of this document that description is referred to as a Graph Template.

We can display a page containing a list of all the currently available Graph Templates by clicking the Graph Templates entry on the Cacti main menu. Figure 4.1 As you can see in Figure 4.1 [The Graph Templates page], above, the Graph Templates page includes is a link labelled Add which will enable us to create a new Graph Template describing how we would like Cacti to graph the temperature data we obtained in the previous section.

This guide demonstrates how to enable the open source radeonhd driver. Version: 11.2+This applies to openSUSE starting from 11.2. Supported hardware Here is a complete list of hardware supported (taken from the radeonhd man page in 12.2; package: xorg-x11-driver-video-radeonhd, version: 1.3.0_20100512_80ba041. For the list maintained by the mainstream project site, see the External links): Enabling Radeonhd If your device is supposed to be supported, you can follow this procedure to enable the radeonhd driver. Disable KMS Add nomodeset to your kernel boot options to disable KMS; radeonhd doesn't support it.

Оригинал: Image Processing with OpenGL and ShadersАвтор: George Koharchik Дата публикации: 22 Ноября 2010 г. Перевод: А.Панин Дата перевода: 22 Декабря 2012 г. При помощи технологии OpenGL и библиотеки GLUT вы можете ускорить процесс обработки изображений, используя всю мощь видеоадаптера вашей системы. Видеоигры в течение многих лет используют все возможности видеоадаптеров. Сегодня даже программные продукты, не работающие напрямую с графикой (такие, как Mathlab) начинают использовать возможность выполнения сложных математических расчетов при помощи видеоадаптера. Вы также можете использовать эту возможность.

В этой статье приводятся примеры использования шейдеров OpenGL для обработки изображений. Изображения выдаются устройством, использующим интерфейс Video4Linux (V4L2). Программа Glutcam получает данные от устройства V4L2 и отправляет устройству с поддержкой технологии OpenGL для их обработки и вывода. Устройства Video4Linux2 Вторым важным моментом является выходной формат. OpenGL. Wiki - RadeonFeature.

Lizards. AMD/ATI Catalyst fglrx & fglrx legacy news Explanations of Hell During June, with the version 12.6 (8.980) AMD decide to drop support for legacy radeon chipset from its main fglrx package and drop the time based release cycle. So now if you are the owner of radeon hd2xxx to hd4xxx chipset family you will have to use the -legacy- version of fglrx, and consequently if you have a radeon hd5xxx or above, you have to use the standard fglrx driver. Then start the hell. After getting the new developed script from Sebastian Siebert, I will be able to offer the two versions. Unfortunately the two drivers can’t coexist in the same repository, the legacy drivers wants to install in place of normal one.

I need your help to spread those informations around the internet, and be sure that every user that need this driver know where and how to use it right. Release note about 12.6 and legacy 8.97.100 Both version can handle kernel 3.4 and 3.5 Sebastian Siebert warn us about the state of legacy Quick Résumé. Welcome to PowerTOP | PowerTOP.

Download ATI Radeon Linux Display Drivers 12.8 / 12.11 Beta 11 for Linux - ATI/AMD Radeon Linux Display Drivers. AMD Catalyst (formerly ATI Radeon Linux Display Drivers) is a free project that tries to distribute proprietary drivers for all ATI and AMD Radeon graphics cards on Linux-based operating systems.

It provides support for TV output on AMD graphics cards that support TV-out functionality. In addition, it allows for the following monitor arrangements: Laptop Mode, Clone Mode, Big Desktop, and Dual Head. While the Laptop mode lets users to toggle between internal or external screen of a laptop, the Clone mode will display the same content on both monitors. Furthermore, the Big Desktop option will stretch a single desktop across two screens, and Dual Head separates instances of X running on each screen.

The drivers suite provides native graphical installers for both 32-bit and 64-bit architectures, and it is known to work well with the major Linux operating systems, including Red Hat Enterprise Linux, SUSE Linux Enterprise, openSUSE and Ubuntu. Ati radeon linux display drivers - Google Search. AMD Catalyst. Owners of ATI/AMD video cards have a choice between AMD's proprietary driver (catalyst) and the open source driver (xf86-video-ati). This article covers the proprietary driver. AMD's Linux driver package catalyst was previously named fglrx (FireGL and Radeon X).

Only the package name has changed, while the kernel module retains its original fglrx.ko filename. Therefore, any mention of fglrx below is specifically in reference to the kernel module, not the package. Catalyst packages are no longer offered in the official repositories. Compared to the open source driver, Catalyst performs worse in 2D graphics, but has a better support for 3D rendering and power management. Installation There are three ways of installing Catalyst on your system.

Before choosing the method you prefer, you will have to see which driver you need. Note: After the instructions for every method of installing, you will find general instructions everyone has to perform, regardless of the method you used. Configuring X. ATI Catalyst™ Proprietary Display Driver. ATI. Owners of AMD (previously ATI) video cards have a choice between AMD's proprietary driver (catalyst) and the open source driver (xf86-video-ati).

This article covers the open source driver. The open source driver is currently not on par with the proprietary driver in terms of 3D performance on newer cards or reliable TV-out support. It does, however, offer better dual-head support, excellent 2D acceleration, and provide sufficient 3D acceleration for OpenGL-accelerated window managers, such as Compiz or KWin. If unsure, try the open source driver first, it will suit most needs and is generally less problematic (see the feature matrix for details).

Naming conventions The Radeon brand follows a naming scheme that relates each product to a market segment. For a table of core and product series, see Wikipedia:Comparison of AMD graphics processing units. Overview The xf86-video-ati (radeon) driver: Works with Radeon chipsets up to HD 6xxx and 7xxxM (latest Northern Islands chipsets). Installation. Graphics drivers.
