I got the issue when I play flash games or videos it's too slow. I reinstalled Ubuntu and it worked smooth for like 5 hours then I rebooted and it was slow again.

When I type
sudo lshw -C display

   description: VGA compatible controller
    product: RS690M [Radeon X1200 Series]
    vendor: Hynix Semiconductor (Hyundai Electronics)
    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 rom
    configuration: driver=radeon latency=64
    resources: irq:42 memory:e0000000-efffffff memory:fe9f0000-fe9fffff ioport:ee00(size=256) memory:fea00000-feafffff

And when I type lspci | grep VG

   01:05.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI RS690M [Radeon X1200 Series] 

I tried this page but when I type glxinfo | grep OpenGL it brings this: The program 'glxinfo' is currently not installed. You can install it by typing: sudo apt-get install mesa-util

Can you help me with this? I just want to keep watching my series on mi lap and play non-hardcore graphics games

To execute the command glxinfo | grop OpenGL, you must have glxinfo installed. To install glxinfo, execute sudo apt-get install mesa-util in a terminal. However, I this will only show you some information, and I don't think it will solve your second problem with poor graphics performance (I still experience it, looking for a different solution). – Rasmus Feb 8 '13 at 19:06
