In case you're only interested in the Dash to start application, you can simply uninstall lenses with sudo apt-get remove --purge unity-lens-[lensName]. As advised by BullfrogBlues here, that most likely means removing all of them except for unity-lens-applications and possibly unity-lens-files. In case you like the Ubuntu system but feel like Unity is ...

The number on the left is seconds (and microseconds) since boot. Look for big jumps. Your USB startup probe (3-18) is taking a really long time. This might be worth investigating. And USB again, (31-44) under udev is slow Then there's a 4-second pause at 46.699188, after the USB touchscreen initialises. Noticing a theme here? Something in your USB setup ...

I had the same problem with Ubuntu 14.10. The problem was solved when I upgraded Ubuntu to 15.04. BTW "Adobe Brackets" is also gets normal from "very slow".

I am the maintainer of two games on Wine HQ. So I can tell from experience. Gaming Under Wine is not that BAD. I maintain NFS Hot Pursuit and NFS Most Wanted on Wine HQ and most reviews are positive on Wine. Being an Game Maintainer I can understand what Wine can and cant do. Most games that are more than 4-5 years old have high chance of running well ...

The other answers say a lot, already. However, make sure you're using the optimal video card driver for your system. Using the wrong one can really slow it down. The best one for my system on Xubuntu 15.04 is the legacy Nvidia one. The newest version and the open source one are either slower with certain applications (such as Tkinter apps and SciTE), or they ...

Despite some of the comments made here, wine is not up to playing modern games. Check this database: https://appdb.winehq.org/ for any titles you would like to play. I recommend dual boot, not without a lack of trying to the contrary. James

System Settings > Software & Updates > Additional Drivers Tab "Using X.Org X server..." must be selected. Select one of the others. A loading bar will be displayed. When it loads you will see a black screen. Then you will see the Ubuntu 14.10 screen. Reset the computer. If it's still slow choose one of the other drivers.

It is not a good idea to install old versions. And Ubuntu 12.04 is slower than 14.04 on old hardware in many cases. But for your laptop I would suggest to install Lubuntu 14.04. It does not have enough RAM to work with Unity well.

For CPU-intensive calculations smaller CPU lithography is better. There is less heat dissipated from the CPU and less fan noise. An SSD will give better performance than an HDD. The SSDs manufactured by Intel and Samsung have built-in TRIM support in Ubuntu. List of Thunderbolt-compatible devices

Just for reference I am currently using Xubuntu 14.04 and experiencing no freezing in regards to starting applications that were pre packaged with Xubuntu. I have 4GB of RAM and about 650MB are what I regularly use with Firefox open. What you really need to understand about Xubuntu is that not only is the Desktop Environment which is XFCE light but the ...

Try adding vm.swappiness=0 to the end of /etc/sysctl.conf and reboot or set swappiness to zero. This way you will not hit disk swap until you run out of RAM. You can also try disabling Akonadi: https://userbase.kde.org/Akonadi#Disabling_the_Akonadi_subsystem http://www.my-guides.net/en/guides/linux/how-to-disable-nepomuk-strigi-and-akonadi-in-kde4 ...

The performance is a lot behind the performance of an installed system. Eg.the start of the various programs may take some time. I would install the two systems in parallel and then decide.

Sure you can improve performance and run Ubuntu on even less powered computers. What will help you to achieve this is to choose a lighter window manager. And, along with @Uwe Plonus sugestions (Xubuntu or Lubuntu), I have tested and recommend Ubuntu Mate I know this implies in a new/fresh install, but it's worth every minute spent. Ah! Welcome to Ubuntu ...

Are you using the default Ubuntu? Try some derivates like Xubuntu or Lubuntu because they use a window manager that uses less resources than Gnome, which is the default window manager for Ubuntu. You can also try installing XFCE (the window manager from Xubuntu) or LXDE (the window manager from Lubuntu) manually and use them (but tis is a bit more ...

There is an extra s in your /etc/default/grub. Remove the s and save the file. After that run this: sudo dpkg --purge linux-image-3.13.0-32-generic sudo apt-get update sudo apt-get -f install

Only minutes after posting this question, the initial resync cancelled itself again by moving the oldest of my disks to a "spare" location, before even hitting 100%. Even though the device did not reveal any smartclt issues, it turned out that it was in fact broken. This was established by badblocks, which revealed thousands of broken sectors. Replacing ...

What I would advise, is have everything in one big / partition on the SSD (including your home directories), and then, if the SSD is not big enough for all your large files, mount your HDD separately as, say, /media/BigHDD or whatever, and put your large files there. That way, all your dotfiles (files and directories beginning with a dot in your home ...

The high cpu usage would mostly likely be attributed to cpu/gpu interactions mainly due to the compositing and the stock window manager; running somewhere north of 300 processes 'out of the box' at start up. As an alternative install openbox, which will then become your window manager. By doing so you drop your cpu processes in idle stat from around 320-380 ...

Seeing that all resources are short (memory and disk) I upgraded my image to a new server with 4GB of ram and double the disk size and everything is back to normal. Nice and fast Thanks for all your help.
