You can select the methods via sysfs. Echo "dynpm" or "profile" to /sys/class/drm/card0/device/power_method. "dpm" support, must be selected at boot (via radeon.dpm=1) and is only supported on R6xx and newer asics.
Try modinfo -p radeon to find up-to-date parameters. To check default values look at drivers/gpu/drm/radeon/radeon_drv.c or drivers/gpu/drm/amd/amdgpu/amdgpu_drv.c in Linux kernel source. To check current values look at /sys/class/drm/card*/device/driver/module/holders/radeon/parameters/ or /sys/class/drm/card/device/driver/module/holders/amdgpu/parameters/*

No, when you install the graphics drivers, it includes direct3d and GL acceleration in its various files.
If a program uses GL, such as Counter Strike, it will use GL.
For your laptop, try to get the drivers from the maker of your laptop. They should have a version for your OS.
radeon is a family of open source graphics drivers for older AMD/ATI Radeon graphics cards. Cards based on Graphics Core Next (GCN) 2.0 "Sea Islands" are also fully supported by the newer AMDGPU driver, which also features experimental support for GCN1.1 (Southern Islands). Neither this nor the AMDGPU article cover installation and configuration of the closed source drivers (see the next paragraph).
Be aware AMD has dropped the support for closed source fglrx drivers (called Catalyst on Windows). The fglrx drivers only work with certain versions of the X server. This is contrary to the open source drivers, which are now compiled against the system's currently installed kernel and X server.
Portage uses the VIDEO_CARDS variable for enabling support for various graphics cards. Setting the VIDEO_CARDS variable to radeon (see the feature matrix above) then asking Portage to rebuild the @world set will pull in the correct driver for older radeon cards:
I recommend using two entries in GRUB (with and without DPM) and creating a startscript based on the value of /sys/module/radeon/parameters/dpm (0 = DPM off, 1 = DPM on), in order to automatically adjust the power management, based on the decision at boottime (single-head with DPM vs. multi-head without DPM).
If you are using a kernel older than 3.13, HDMI audio must be explicitly enabled using the kernel commandline paramater radeon.audio=1. In addition, ALSA typically does not use HDMI as the default audio, so one way to force this as the default is to add a config file:
This is likely a public supported driver for your distro (if it exists) that gpu is no longer supported and only legacy drivers exist. I would as the question in your support forum for your distro. If none can be found you might look into another flavor of Unix? Ubuntu has pretty decent support from their community for the older AMD gpus. Not say debian does or does not. I just don't have much experience with that.
I would like to know what is the state of the radeon-pilote power-management avancements with the kernel 2.6.34.
I search to improve my thermal management of my HD3650 ATI card. Not long ago I experimented different way to resolve my problem :
It was obvious that the 13.2 upgrade broke something when the resolution was all funky upon the restart. Fortunately, I recognized this from my initial install. First, I checked to see if the kernel module for the graphics driver was loaded (radeonkms):
Until logging in, the system works OK, while logging in SDDM, it shows the entered user data and password slowly, with a delay, a black screen appears for a second and the login screen is back.
I think it might have something to do with X.
I installed xorg-x11 and x11-drivers / xf86-video-ati-19.1.0-r1
AMD Catalyst is being developed for Microsoft Windows and Linux. As of July 2014, other operating systems are not officially supported. This may be different for the AMD FirePro brand, which is based on identical hardware but features OpenGL-certified graphics device drivers.
The included manual is a generic installation guide that explains how to attach the card into a PCI Express slot and plug in video cables into the appropriate slots. Diamond doesn't provide any additional software with this card aside from the basic drivers needed to install it. So it's a little spartan, to say the least. This isn't an expensive card, and we weren't expecting free hats or t-shirts or even stickers with funny slogans on them - but it never hurts. ff782bc1db
