My laptop is Thinkpad T400 with Ubuntu 12.04. My GPU is ATI graphics module, if I am not mistaken. I wonder how I can scale GPU frequency? software and/or shell script are acceptable. For cpu frequency, I use cpufreq to set the cpu frequency to the lowest 0.8GHz from five scales, and it also offers several auto-adjusted options (performance, on demand, power save, conservative). Are there alikes for GPU?
Can I scale GPU frequency?
