An Intel Graphics processor uses the main CPU to perform its graphics rendering, so it's basically the kernel eating up these processor cycles... Solution? Switch to LUbuntu: much less graphics intensive and giving you all the functionality you need to perform all the tasks you need for day-to-day usage (mail, web, and simple games) If you want the ...

In the running system, you can get rid of intel_powerclamp: sudo rmmod intel_powerclamp To disable it permanently and suppress loading it altogether, in addition do: cd /etc/modprobe.d sudo su echo install intel_powerclamp /bin/true >intel_powerclamp.conf Then, after a reboot, it wont come back.

Your intuition is correct, there should not be a significant performance problem in the case of an XBMC box. If you think about it, this is almost exactly what the Raspberry Pi does, although technically it uses an SD card rather than a USB drive.

This was caused by SMART data being enabled for the drive in question. Disabling SMART data solved this : sudo smartctl --smart=off /dev/sda Presumably it kept rerunning some kind of internal self-test 30 minutes after the disk spun up and got into a loop; as this was at the hardware layer the rest of the computer was unaware of it going on hence I ...

First you should open the terminal input the command free, then past the results it here. So that we may help you. If you prefer here are some patches not solutions: I would recommend a full clean install. (at the bottom I have explained how to do it) A quick patch not a solution might be installing gnome partition editor. Then resize your partition. The ...

Which size division are you in? I realize this may not be the answer you're looking for here, but for something time critical like standing up within 10 seconds, I would go with an embedded platform. If you have the space / power budget, you should consider sticking something like an arduino on the robot, and programming some open-loop stand-up behaviors. ...

The FSB and RAM speeds will also be slower than newer computers, which will doubtless be adding to the delays. I would say you might be better with a low-overhead distribution such as LUbuntu or LXLE. I have a couple of older laptops that by rights should be fine, but don't seem to cope with the latest distro either. Such is life, unfortunately. You can ...

You probably don't have 3D acceleration, which Ubuntu needs. If 3D acceleration is not found, Ubuntu uses the CPU instead of the GPU to let appear some image on your screen. That's very CPU-intensive, so that's probably why your computer is so slow. Also, the hardware architecture (64 bit vs 32 bit) won't matter. You can try installing the proprietairy ...

Try reducing storage buffer to 4 MB. In /etc/sysctl.conf write: vm.dirty_bytes = 4194304 vm.dirty_background_bytes = 1048576 also maybe reduce writing time to 3 seconds vm.dirty_expire centisecs = 300 vm.dirty_writeback_centisecs = 300 Please comment if this helped or not. Thank you.

All this iso images contains a squashfs image of the file system. Bevor the start it will be copied into the RAM. In most cases this is the slowest part of booting a LiveCD. SquashFS Image file for Ubuntu 14.04.1 64 Bit: 984MB CD/DVD: 21,12 MB/s - Reading speed USB 2.0: 32MB/s - Reading speed It takes 04 minutes and 17 seconds to copy the squashfs file ...

This is one of those applications where you basically start subtracting until you break something and then back off. Like for instance, I don't think your robot is likely using zeroconf which is the avahi daemon, so uninstall it. Do you really need networking? Or better, boot into single user mode (append 1 to kernel cmdline) and then see how many services ...

I am not sure if a server installation of Ubuntu is really the right way to go, because of what you are describing sounds like a job for archlinux or similiar to me. You will need to do a lot of customization on your system, which is when a "take a base system and add anything needed" approach is easier than a "use a full-fledged installation and remove ...
