My system freezes randomly while using Google Chrome, Mozilla Firefox. Mouse works but I am not able to click anywhere. By pressing ctrl + alt + f1 I can get into command shell but, there I do not find anything other than a login option.
The only option left with me is going for sudo poweroff
or reboot.
My system configuration is as follows:
- Core2Duo 2.0ghz
- 3GB RAM DDR2
- 256MB ATI mobility Radeon HD3400
- 320GB sata hard drive
- I am using gnome shell with gallium 0.4 amd on rv620 not the restricted ATI raedon drivers.
I have also discovered that while scrolling in Firefox/Chrome the CPU usage of Firefox/Chrome and GNOME-Shell increases a lot around 60-80 percent each depending upon the scroll speed.
Also on typing dmesg
in the terminal at the end I found the following :

When the system freezes, pressing super button several times the system logs out to the login screen.
