Using the guide: http://wiki.debian.org/ATIProprietary I did the following steps:
1) aptitude install --without-recommends linux-headers-$(uname -r) 2) aptitude install fglrx-control fglrx-driver 3) aticonfig --initial
I can run xwindow and control the fan speed, catalyst control center also loads up. Video card is HD 5770. I installed the proprietary drive because I want to control the fan speed.
However, when I login, the background wallpaper rendering is lagging (sort of looks like a vsync issue). When playing flash 1080p videos, it is very choppy and uses high cpu.
Running fglrxinfo shows the following:
display: :0.0 screen: 0 OpenGL vendor string: ATI Technologies Inc. OpenGL renderer string: ATI Radeon HD 5700 Series OpenGL version string: 4.0.10188 Compatibility Profile Context
The device section of xorg.conf looks like this:
Section "Device" Identifier "aticonfig-Device-0" Driver "fglrx" Option "Monitor-DFP1" "0-DFP1" Option "Monitor-DFP3" "0-DFP3" Option "UseFastTLS" "1" Option "VideoOverlay" "off" Option "TexturedVideo" "on" Option "OpenGLOverlay" "off" Option "TexturedVideoSync" "on" BusID "PCI:1:0:0" EndSection
Running fgl_glxgears shows
using glx_sgix_pbuffer and renders 1268FPS
Running fgl_glxgears with
-fbo switch shows using gl_ext_framebuffer and renders 2200FPS
Running glxinfo | grep rendering shows
direct rendering: Yes
Running glxinfo | grep direct:
direct rendering: Yes GL_ARB_draw_indirect, GL_ARB_draw_instanced, GL_EXT_copy_buffer, GL_EXT_copy_texture, GL_EXT_direct_state_access,
When I do video info on 1080p youtube videos, it says software rendering and software decoding. Running fglx_gear also uses high cpu. html5 videos are using high cpu.
