Older cards use EXA.ĭRI3 is enabled by default since xf86-video-ati 7.8.0. Please read radeon(4) and RadeonFeature first before applying driver options.Īcceleration architecture Glamor is available as a 2D acceleration method implemented through OpenGL, and it is the default for R600 (Radeon HD2000 series) and newer graphic cards. The following options apply to /etc/X11// nf. || radeon-profile-git AUR Driver options
radeon-profile - Qt application for displaying info about a Radeon card. Note: It is required to set a kernel parameter ( amdgpu.ppfeaturemask) in order to enable the AMD Overdrive technology within GNU/Linux. WattmanGTK - A GTK3 user-interface written in Python 3, which allows you to view, monitor Radeon performance, fan speeds and power states and the ability to overclock the graphics processor. Performance tuning Enabling video acceleration Using this section, you can enable features and tweak the driver settings. If you want manual configuration, create /etc/X11//nf, and add the following: Configuration is only required for tuning the driver. Xorg will automatically load the driver and it will use your monitor's EDID to set the native resolution. Also, check that you have not disabled radeon by using any kernel module blacklisting. Make sure you do not have nomodeset or vga= as a kernel parameter, since radeon requires KMS. The radeon kernel module should load fine automatically on system boot. Support for accelerated video decoding is provided by mesa-vdpau and lib32-mesa-vdpau packages. For the DDX driver (which provides 2D acceleration in Xorg), install the xf86-video-ati package. For 32-bit application support, also install the lib32-mesa package from the multilib repostory. Install the mesa package, which provides the DRI driver for 3D acceleration. See the feature matrix to know what is supported and the decoder ring to translate marketing names (e.g. If unsure, try this open source driver first, it will suit most needs and is generally less problematic. 13.10 Horizontal flickering occasionally when using 4k DP output on 390Xĭepending on the card you have, find the right driver in Xorg#AMD. 13.9 QHD / UHD / 4k support over HDMI for older Radeon cards.
