I recently reinstalled Ubuntu 11.04 Natty after a massive hard drive failure.
Now, for some reason, compiz and Xorg decide it's a fun idea to start eating up my RAM and CPU - GB by GB. Starts out at normal amounts, but quickly balloons to 1-2+GB and starts using most of my CPU. This never happened before, but none of my hardware has really changed. The only difference being that I installed 11.04 cleanly, whereas before I had upgraded from 10.10.
For example: Rebooted my computer last night. Only program running is Transmission. Come back this morning - Xorg is using 1.5GB RAM and over 50% of my CPU. There is NOTHING else running or installed. I haven't activated any fancy Compiz plugins at all. What gives?
I'm running 11.04 on a 4x AMD Athlon(tm) II X4 640 Processor with 8GB RAM. I'm using the integrated ATI Radeon HD3300 GPU with the AMD Catalyst 11.5 driver - but this problem occurs with the 11.4 AND built-in fglrx drivers as well.
I can give any other logs or sysinfo if that is needed.
