Installed Ubuntu in Inspiron 15R SE. How to optimise system?

Asked by Account Deleted

My Dell Inspiron 15R SE came with Windows 7OS and I installed Ubuntu 12.04LTS. Is there any system settings I should change to get my system to work optimally?

I am concerned about laptop cooling, touchpad compatiability (although its working fine now, is there any other drives/anything else I should get), battercy charging/discharging and life..

All the systems are working great as of now I guess. At least, touchpad, screen, keyboard, sound etc are working smoothly. Battery charging is also going good I guess.

I still have my Windows in my HDD as I used the Windows installer to install the Ubuntu

You can run:
gksudo gedit /etc/default/grub

fine the line:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

change it to:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash ipv6.disable=1"

Save the new file and run:
sudo update-grub; gksudo gedit /etc/sysctl.conf; sudo sysctl -p

Add the below text:

net.core.rmem_default = 524288
net.core.rmem_max = 524288
net.core.wmem_default = 524288
net.core.wmem_max = 524288
net.ipv4.tcp_wmem = 4096 87380 524288
net.ipv4.tcp_rmem = 4096 87380 524288
net.ipv4.tcp_mem = 524288 524288 524288
net.ipv4.tcp_rfc1337 = 1
net.ipv4.ip_no_pmtu_disc = 0
net.ipv4.tcp_sack = 1
net.ipv4.tcp_fack = 1
net.ipv4.tcp_window_scaling = 1
net.ipv4.tcp_timestamps = 1
net.ipv4.tcp_ecn = 0
net.ipv4.route.flush = 1
vm.swappiness = 10

Reboot to test, should make the network a little smoother. Which desktop do you use?

Can you please explain a bit more. I am an idiot when it comes to computers.

Presently, I use a laptop - Dell Inspiron 15R SE.

Earlier, I had a Dell Vostro 1310 laptop in which I installed Ubuntu. The OS worked fine without any prblem, but my laptop battery got trashed because the system heats up faster than it did when running on windows and I never took care of it.

So, I dont want to make the same mistake with my current one. Thats my only concern.

Is there anything I should do/change to use Ubuntu on a laptop made to run on Windows.

Unlike Windows Ubuntu makes it easy for you to choose the "desktop" or Graphical front end.

If you installed Ubuntu opposed to Lubuntu, Xubuntu, Kubuntu then the default desktop is Unity but you can change it does it look like the picture in this link ?

If yes then its Unity. That's what Andrew is asking. I'm not sure why but he will probably be able to suggest further optimisations.

Unity isn't a desktop. It's a shell for the Gnome desktop

The desktop looks exactly like the one in the link posted.

Then you are using Gnome desktop with Unity shell. If you run:

sudo apt-get install compizconfig-settings-manager; ccsm

You can disable Compiz plugins to make the OS lighter. If you don't use the Windows style 'snap' feature you can disable the grid plugin, and so forth. I persoaly like to diable the animations to make the OS more responsive.

Yup. got it. It lightens the OS i guess. I hope I get what I am looking for.
Anyways, thanks everyone for your help and information. will get back to you if i have any other similar issues.
