![]() Additionally, shutting down Nepomuk means that pulseaudio works better – I’m guessing because pulse isn’t getting CPU/io starved because of nepomuk’s endless indexing. Nepomuk just never seems to stop indexing and I definitely notice the load. This is probably because I have a huge $HOME directory with a bajillion text files for my development projects along with three very large email accounts. You may not need to do this, but I’ve found it’s just too large a resource hog for me to keep it enabled. Nepomuk: Go into “System Settings -> Desktop Search” and disable Nepomuk (boo!). This will give you access to a significant number of effects that work pretty well under the intel integrated gpu. Reboot the cpufreqd daemon after changing the config file, of course.Įffects:Go into “System Settings -> Desktop Effects -> Advanced” and switch the compositing type to “XRender”. I suggest changing every “policy=” in /etc/nf to “ondemand” and every “minfreq=” and “maxfreq=” setting to 0% and 100% respectively.You can tweak nf endlessly, but these minor changes make a HUGE difference with no noticeable impact on performance. I really, really like the “ondemand” governor as it means a cooler running system that’ll use the full capabilities of your CPU when needed. This will clock down your CPU according to different profiles and lead to major power savings.The default cpufreqd config needs tweaking, as it’s really not optimized well for the full capabilities of the linux kernel/i5 hardware combo. Thanks to this page for the boot options. Update grub after making this change, via “sudo update-grub”. This will light up a bunch of hotkeys and power management features. GRUB_CMDLINE_LINUX_DEFAULT=”quiet splash pcie_aspm=force acpi_osi=Linux i915.i915_enable_rc6=1″ kernel boot options: edit /etc/default/grub, and change GRUB_CMDLINE_LINUX_DEFAULT to be:.After the installation is complete, you have a few more linux-level tweaks to implement. You should probably leave the 18gb and 100mb recovery partitions alone so you can factory-reset the machine easily should you decide to sell it later on. I created a 35gb / partition, 5 gb swap and 240gb /home, but go with what you like. ![]() Your wifi and ethernet cards should be recognized without a problem. Don’t get me wrong, the ironhide/bumblebee folks have done some great work and I’m looking forward to full optimus support in the near future.This BIOS change means if you want to use the nvidia GPU under windows that you’ll need to go into the BIOS during a reboot and change back to “switchable.” That’s a fine compromise as far as I’m concerned (98% of my time is in linux, I only use windows for games), and the fact that Acer makes this a BIOS option is great – my Asus 1215n didn’t have this option so the nvidia GPU was always on. I was able to get it working (for some values of “working”) but it was VERY quirky to the point of being unusable. Change the boot priority to use the USB device, or enable the “boot menu via f12” option that’s in there.While you’re in the BIOS, switch the graphics to “integrated.” This will power down the nvidia GPU and lead to some pretty major power savings.Yeah, this kinda sucks, but switchable graphics through ironhide is just not there yet. BIOS updates: Reboot, going into the BIOS by pressing f2 during the POST. ![]() Leave the space unallocated, you’ll partition it through the kubuntu install process. I did this through windows, but whatever makes you happy. ![]()
