I am assuming mistr has similar hardware as my Compaq Evo N610c laptop,
which only has 32mb vram (dedicated card, not shared)

01:00.0 VGA compatible controller: ATI Technologies Inc Radeon Mobility M7 LW [Radeon Mobility 7500]
        Subsystem: Compaq Computer Corporation Device 00b7
        Flags: bus master, stepping, 66MHz, medium devsel, latency 66, IRQ 11
        Memory at 48000000 (32-bit, prefetchable) [size=128M]
        I/O ports at 3000 [size=256]
        Memory at 40400000 (32-bit, non-prefetchable) [size=64K]
        [virtual] Expansion ROM at 40420000 [disabled] [size=128K]
        Capabilities: [58] AGP version 2.0
        Capabilities: [50] Power Management version 2
        Kernel modules: radeon, radeonfb

To fix this problem, I simply needed to create an xorg.conf with this:

 Section "Device"
	Identifier	"Configured Video Device"
	Driver             "radeon"
	Option         	"AccelMethod"    "XAA"  
	Option 		"RenderAccel" "off"
	Option         	"EnablePageFlip" "true" 
EndSection

The EnablePageFlip seems to remedy some graphical artifacts during
Kubuntu's login

As a side note, in Kubuntu all the plasma components show this graphical
corruption: the taskbar, main menu, window decorations, etc.
