I upgrade from 12.04 to 13.04. After I reboot i met "the system is running in low graphic".

my graphics driver is amd-driver-installer-catalyst-13-4-linux-x86.x86_64.

After I remove the driver I can get into the system, but only see wallpaper, but can use terminal but can't switch, and can't move either, and system crash information always pop out.

My xorg.conf

Section "ServerLayout"

Identifier "aticonfig Layout"
Screen 0 "aticonfig-Screen[0]-0" 0 0 EndSection

Section "Module" EndSection

Section "Monitor"

Identifier "aticonfig-Monitor[0]-0"
Option "VendorName" "ATI Proprietary Driver"
Option "ModelName" "Generic Autodetecting Monitor"
Option "DPMS" "true"

Section "Device"

Identifier "aticonfig-Device[0]-0"
Driver "fglrx"
BusID "PCI:1:0:0"

Section "Screen"

Identifier "aticonfig-Screen[0]-0"
Device "aticonfig-Device[0]-0"
Monitor "aticonfig-Monitor[0]-0"
DefaultDepth 24
SubSection "Display"
Viewport 0 0
Depth 24
EndSubSection EndSection

$ glxinfo
name of display: :0.0 Error: couldn't find RGB GLX visual or fbconfig

I have tried many ways that i found, but i can't work out, all day. Anyone can help?
