End of life for Ubuntu 12.10 is May 16, 2014. Ubuntu 12.04 is April 2017. However Ubuntu 14.04 is already out and is most updates one. Hence, please use that to be at the better side. Now, for the performance issue; go to Software Center and type "LXDE" and install the first option. You may use this command in terminal as well: sudo apt-get install lxde ...
Just install a realtime (package name "linux-lowlatency") kernel and gnome will be smooth. Use synaptic packet manager to find it, also you can uninstall the generic kernel to round things up.
Worked it out, the syntax was wrong in the command line. Used the following which returned the report: > db.system.profile.find()
Have you tried Glances ? Refer this link, it has some thing in common. System Monitoring Tools For Ubuntu Best of luck !!
top has a batch mode (-b) that generates output without the screen control codes. By adding some other switches and options, you may be able to focus in on the stats you need and redirect it to a file or other program for processing.
Sysstat is your friend, assuming you are fine with using the command line. Have a look for examples here for memory usage, and here for cpu usage.
Yes. The drivers can have a big impact. The open source driver is likely to be more careful about which advanced features of the card it uses because the developers don't have access to hardware specs and resources. The official drivers will use more advanced features so should be faster, but depending on the level of testing, can also be more unstable. ...
Have you checked your swap file in System Monitor/Resources - though it was working OK in 13.10 - it has not been activated when I upgraded to 14.04 on my laptop.
There's also gnome-session-flashback which should look familiar if you have used previous iterations of Ubuntu. Apart from having a similar look-and-feel, it is also less resource-intensive.
You are extremely likely to have 2 relevant bottlenecks: the low amount of RAM available to the system, which in some cases is even less then the nominal value, for example if your GPU is stealing some RAM from the system the total amount available to the system is obiviously 1Gb - WhatTheGPUIsUsing the slow HDD. Tipically old notebooks have a 5400rpm ...
Two things: 1) Ubuntu 14.04 uses Unity 3D, which is based on Compiz. The whole thing is rendered through hardware-accelerated OpenGL. This is fantastic if you have good drivers and a good video card, not so much if either is missing. There is absolutely no need to switch distributions. Just install a lighter desktop environment, log out, and log back in to ...
Because you only have 1GB of RAM! That isn't the only problem, but it is part of it. Simply, your computer can't handle the intensity of Unity's graphics. Windows XP is not nearly as CPU / Graphically intensive as Unity, the default desktop of Ubuntu 11.04+. It is based on compiz and has all sorts of fancy graphics, such as the see through dash and the ...
though quite late in replying, maybe this will be useful to someone. I have been and still am using an Acer Aspire One 725 with C60. it was working ok with 2GB RAM, though I have upgraded this to 8GB RAM. I've had issues with the wifi driver, sound, SD card reader, screen brightness, and some function buttons when I first bought it. however, all issues ...
Here are some ways to optimize ubuntu for performance: 1. Optimize disk access with noatime: Each file and folder on your linux system has a file-creation timestamp and a modification timestamp. Apart from that, linux tries to keep track of “access time” for each of these files. Now keeping track of the access time has its performance-cost, and if you want ...
I strongly suspect the network load itself is not the issue here. More likely, it's the network activity's effect on your HDD (as data is read and written to it). Try doing some intensive HDD activities, checking the mouse symptoms under load. Writing a large file via dd is a simple solution. Here's a succinct guide on how to do so. You could also watch ...
Install ccsm, open terminal (Ctrl + Alt + T or from the dash) and paste line below: sudo apt-get install compizconfig-settings-manager Run it from the dash or in terminal ccsm. Choose OpenGL in General category and change Texture Filter from Good/Best to Fast. Go back and choose Ubuntu Unity Plugin in Desktop category and change Dash Blur from Active ...
I believe what you are looking for is ubuntu's 2d mode, but it was removed in 12.10. I found an article that mentions a way to disables some of the additional eye candy. I'm not sure if this is still available in 14.04, but you can try it by adding 'export UNITY_LOW_GFX_MODE=1' to the '.xprofile' in your 'home' folder. If you want you can just run the ...
Overall unity is hard to configure performance wise, though on those specs it should run reasonably well. If you have a chance to upgrade the ram, I recommend it highly, though it should run just fine on that for normal use (just don't expect to be doing video editing/custom rom compiles/basically any modern games)
Maybe this will help... I'm using nvidia both at home and at work. In the one machine I have a GX550 Ti (home) and in the other 2 Quatro 2000 cards. On both machines I have 3 monitors connected. To make this work I had to config each monitor on there own xserver. In Nvidia X Server Settings->X Server Display Configuration select the monitor which is ...
