I'm using a laptop (Intel Pentium Dual T3400, 2GB RAM, Intel GL40 chipset), dual-booting with Windows Vista Home Premium and Ubuntu 9.10. Majority of the time, Windows is used. However, when I have to write some code, I switch to Ubuntu.
The problem is: When I use Windows, the power saver mode in Vista clocks the CPU down to 1Ghz, but I couldn't find such a mode in ubuntu. I tried using libcpufreq to clock the CPU down to 1Ghz, but it doesn't seem to have the same effect as in Windows. My laptop tends to get heated up faster in Ubuntu than in Windows - 1 hour of Ubuntu produces the same heat as 5 hours of Windows. I don't do much resource intensive work, just coding-compiling-coding (no major projects here). Any ideas? I'm really keen on switching to Ubuntu for all my work, but this heating problem and the lack of games are stopping me from doing so.. (I can manage without games though! )
