so I got this old netbook from a friend and she wants me to make it usable. I installed Xubuntu but it seems that this ESH settings in BIOS which should overclock CPU up to 30% does not work! When I do cat /proc/cpuinfo|grep MHz I still see numbers around 1300 and not 1.74GHz as I hoped even when CPU load is high. I installed this TLP package (http://www.webupd8.org/2013/04/improve-power-usage-battery-life-in.html) thinking that this is necessary to make ESH work, but still it's the same. If I run sudo tlp-stat -p I get

x86_energy_perf_policy: program not installed.

/sys/module/workqueue/parameters/power_efficient = Y
/proc/sys/kernel/nmi_watchdog = 0

Isn't this boost (not available) the problem? Any ideas how to make this CPU work faster? Youtube is unwatchable even at frikin 360p unfortunately like this :-\

What if I just put some number to scaling_max_freq into TLP config /etc/default/tlp? Can I just put there any number of MHz, would it take it?

  • if you are having issue with video quality, you might need different video drivers... can you post output of "sudo lshw -class display" Sep 8, 2018 at 14:45
  • it's not video quality, but videos are super choppy. Like 2fps. Disabling VP9 codec via h264ify FF extension does not seem to help

  • I only ask about video drivers because your laptop sounds faster than my Raspberry Pi, which plays video just fine. what do you get from: glxinfo | grep -i "vendor\|rendering" Sep 8, 2018 at 14:56
  • this command might also give useful info: lspci -k | grep -EA3 'VGA|3D|Display' Sep 8, 2018 at 15:00
  • If a BIOS setting doesn't work, it might be a BIOS problem, unrelated to Ubuntu. That said, even if you could overclock it, it would have done nothing to make the netbook usable. Intel's GMA500 is a well known piece of hardware that doesn't have a proper Linux driver, and Intel can't be bothered to provide one. Basically, that machine is only good as a server.
