I just installed Ubuntu 11.04 on my laptop.
However, very often things get VERY slow and windows start blinking with gray color. The system is then almost unresponsive... This goes on and off in about 5 minutes interval.
When I run the top
command it looks like the Xorg command is using most of the CPU when things get crazy.
I am using HP Compaq 6720s..
lspci | grep VGA
