I'm using a laptop with a Radeon Mobility 2600 graphics card and I've had some problems with it. There is no driver for it in ubuntu so I've tried using no drivers (I believe ubuntu just uses some standard vesa drivers without any GPU acceleration support then?), I've tried using the driver that System->Administration->Hardware Drivers suggests, and I've tried using a driver from the amd website (http://support.amd.com/us/gpudownloa...eon_linux.aspx). All of these have their own problems. I am on a 32bit architecture and I'm on 10.04 Lucid Lynx.
When I use the driver that ubuntu suggests, I have problems with resizing, maximizing, minimizing, and opening new windows, it takes 10 seconds for those actions during which everything freezes, even just to open a new gnome-terminal or nautilus window.
When I used the driver that I get from the amd website, I don't have those problems but instead I have problems with flash player. When I use youtube or twitch.tv, XOrg suddenly starts to eat up my CPU, sometimes eating up 50% (an entire core). Additionally, the sound glitches all the time (but the video is okay).
Without any drivers, nothing really works any well.
I have the glxinfo and the xorg.conf file for both configurations (both the drivers) but I'm not sure if those are relevant though.
I'd post the entire glxinfo but it's quite big so here's the difference.
glxinfo with the amd site driver has this:
glxinfo with the driver Hardware Drivers suggested has this:
client glx extensions:
GLX_EXT_swap_control, GLX_MESA_copy_sub_buffer, GLX_AMD_gpu_association
OpenGL version string: 2.1 (3.3.11566 Compatibility Profile Context)
OpenGL shading language version string: (null)
GL_ARB_vertex_shader, GL_ARB_fragment_shader, GL_ARB_framebuffer_object,
GL_EXT_framebuffer_multisample, GL_EXT_geometry_shader4, GL_EXT_gpu_shader4
Both of them have a ton of other stuff, but they have all that stuff in common.
OpenGL version string: 1.4 (3.2.9756 Compatibility Profile Context)
After I install the driver from the amd site xorg.conf looks like this:
After I install the driver the Hardware Drivers suggests xorg.conf looks like this:
Identifier "aticonfig Layout"
Screen 0 "aticonfig-Screen-0" 0 0
Option "VendorName" "ATI Proprietary Driver"
Option "ModelName" "Generic Autodetecting Monitor"
Option "DPMS" "true"
Viewport 0 0
I'm wondering if you have any advice? I'd like to have both flash player work and windows open and resize instantly and not freeze the system for 10 seconds.

Identifier "Default Device"
Thank you for your help
