Ubuntu 12.10 GPU heats up and system crash
I have recently installed Ubuntu 12.10 in a dual boot configuration with windows 7 on my dell studio-1558 notebook and im experiencing instabilities that i suspect are due to the GPU. the notebook's configuration is:
CPU - i5 M520
RAM - 4 GB
GPU - Mobility Radeon HD 4570
I have checked the GPU temperature using lm-sensors and it was gradually rising and it peaked at around 98C before the pc became too slow to operate or just crashed. the CPU cores temp was also gradually rising reaching 75-80C (before the pc crashed).
for comparison, the GPU temperature in win7 is running much cooler at 60C and CPU cores also at 60C.
I would have installed the propietary radeon drivers but im new to linux and it seems to be pretty complicated and i have also heard that there are incompatablities with ATI's drivers and linux.
I would really like to try Ubuntu out and would greatly appreciate if someone could help me with this issue.
Thanks a lot!
