Performance issue. Perhaps video card/driver related.
I installed Fedora 12 on a new laptop the other day. All my hardware was detected and everything works perfectly. Or almost. Every once in a while, my display will become completely unresponsive or will become very slow. Sometimes I'll be typing in "gedit" and I can type faster than text appears on the screen.
Eventually, after a minute or so, the screen will go back to normal and I'll have good performance again for a half hour or so.
I've checked "top" and nothing seems to be hogging the CPU (total usage is under 10%) and I've got lots of free memory. Since the lock-up usually happens when browsing "heavy" websites or unlocking the desktop, I'm assuming this problem is a hardware/driver issue. I'm using an Intel card, which I understand have had issues in recent past.
To try to improve performance and avoid these lock-ups, I've disabled all desktop effects and scaled my resolution down a little. So far it hasn't helped. Any suggestions?
