It shows Radeon 2000 instead of 4200 and at same time the 3d acceleration doesnt work with the 2000.
Actually, it says "Radeon HD 2000 and later".
Open Synaptic. Search for fglrx. Be sure the dkms-fglrx
packages are installed. According to the ATI page here
, (pdf file) your ATI Mobility Radeon™ HD 4200 card is supported by the catalyst driver.
After making sure you have the packages installed in Synaptic, open the PCLinuxOS Control Center. Click Hardware in the left panel, then Configure Video Card in the right panel. Click the top button which is the Graphic Card button. The correct choice
for your video card should be highlighted by default
. Select it and save all changes.
As you can see by the screenshot, I have an earlier version of an ATI.
