Ok I'm not as feeble minded as I thought. My problem now moves from the General section to here in Laptop Hardware.

I have a Toshiba Satellite L775D.

Specs:
AMD A6-3400M APU with Radeon(tm) HD Graphics, 1397MHz
Realtek RTL8188CE Wireless LAN 802.11n PCI-E NIC WIRELESS LAN

I installed from PCLOS KDE 2011.6 LiveCD in full safe mode. Now after setting up
UN & PWs. The display flickers terribly at user login. I can't login it flickers so bad.
What now kind fellow PCLOSers?

Try running pcc from a VT (Ctrl+Alt+Fn, with n being 1-6) to setup your display with a different driver.

I don't understand. Could I have that in baby steps?

OP is saying to hit Ctrl+Alt+F1  to get a text based command line.  You can have up to 6 of them hence the "1-6". Simply type PCC, and in the menu that comes up, choose Display.  Choose a different Video driver.  Reboot.

I can't find the right combo of settings under display. Any suggested settings?

I tried ATI FirePro (radeonhd/fglrx)
         generic 1600x900
         1600x900 24bpp

My GPU is AMD Radeon HD6520G, 1600x900 resolution & listed as generic 17.3" pnp.

Make sure your kernel is current:

If you're looking to utilize a Radeon HD 5000 series GPU with the xf86-video-ati 6.14.0 driver you will need the Linux 2.6.36 kernel or later. To use the Radeon HD 6000 or Fusion hardware you will need to be using the Linux 2.6.38 kernel."

If none of those drivers work you might try Andy's fix http://www.pclinuxos.com/forum/index.php/topic,92926.0.html
