My system has two dual core AMD Athlon processors and 4GB of memory. ATI RS690(Radeon X12oo series) onboard chips provide the graphics.
Yet the machine seemed a little slow with 12.10 and apps were crashing, including
compiz(compiz was also getting
100%+ of the
cpus at times). I did an inline upgrade to 13.04 and the desktop wouldn't display, I only had a blank screen. I ran the following commands (askubuntu entry):
sudo apt-get remove --purge fglrx* sudo apt-get remove --purge xserver-xorg-video-ati xserver-xorg-video-radeon sudo apt-get install xserver-xorg-video-ati sudo apt-get install --reinstall libgl1-mesa-glx libgl1-mesa-dri xserver-xorg-core sudo dpkg-reconfigure xserver-xorg sudo reboot
and was able to restore the desktop, but I wonder if I'm still using the wrong graphics driver. Running
sudo lshw -c video provided the following info:
*-display UNCLAIMED description: VGA compatible controller product: RS690 [Radeon X1200] vendor: Advanced Micro Devices [AMD] nee ATI physical id: 5 bus info: pci@0000:01:05.0 version: 00 width: 64 bits clock: 33MHz capabilities: pm msi vga_controller bus_master cap_list configuration: latency=64 resources: memory:f0000000-f7ffffff memory:fdef0000-fdefffff ioport:ee00(size=256) memory:fdd00000-fddfffff
so I figured it was seeing the hardware correctly. The ATI RS690 shows to be supported by Ubuntu and should be capable of 3D graphics but
glxinfo | grep renderer shows
OpenGL renderer string: Gallium 0.4 on llvmpipe (LLVM 3.2, 128 bits)
Which I believe is a generic driver. I also get the results below from
/usr/lib/nux/unity_support_test -p OpenGL vendor string: VMware, Inc. OpenGL renderer string: Gallium 0.4 on llvmpipe (LLVM 3.2, 128 bits) OpenGL version string: 2.1 Mesa 9.1.7 Not software rendered: no Not blacklisted: yes GLX fbconfig: yes GLX texture from pixmap: yes GL npot or rect textures: yes GL vertex program: yes GL fragment program: yes GL vertex buffer object: yes GL framebuffer object: yes GL version is 1.4+: yes Unity 3D supported: no
Shows that 13.04 is running software rendering and that 3D is not supported!
Can someone please help me understand why the system is using software rendering and not doing 3D. I'm willing to buy a PCIE gfx card if that's what it takes.
How to fix this ?
