Ubuntu Optimized for Dell Mini with SSD

Ubuntu Optimization for Dell Mini with SSD and Acer Aspire One with SSD

Note:
- The Aspire One must have 1GB (1.5GB max) RAM
- For Dell 1GB Mini9 enough
With these values of RAM, there is almost never swap.

Installation :
I choose the manual installation - automatic start, thus avoiding typing a user password. It must still choose the administrator password.

- 150MB for the swap (only for the health conscious or 0 if you will) and the rest for /

Ext2 format for not logging and limit disk write and ext4 safer in case of power failure during an exchange but more hard disk write-intensive and therefore life of SSD. With 4 ext additional adjustments will be done to limit the records

For ext2:
Edit grub2 to start quickly and reduce the disk write operations:
In a console:

sudo gedit / etc / default / grub - set GRUB_TIMEOUT = "0"

for a start without waiting for the choice of OS or kernel.

-------- For the aspire one: Replace the line GRUB_CMDLINE_LINUX_DEFAULT = "quiet splash" by GRUB_CMDLINE_LINUX_DEFAULT = "quit splash elevator = 1 hp.hp_force = noop" This will automate the insertion of an SD card into the reader right. (Elevator = noop does that SSD)

-------- For Dell Mini9: GRUB_CMDLINE_LINUX_DEFAULT = "quit splash elevator = noop"

To maintain these settings at the kernel updates: Opening a console - type

sudo update-grub

and root password.

To ext4:
To save the DSS Reading disable logging when installing partitions in / etc / fstab add the notime parameter for each partition ext3 or ext4 hosted on the DSS.


Optimize Firefox:
Avoiding unwanted deadlocks while using Firefox when SSD:

- Launch Firefox and type about: config in place of the URL
- Assign the value 0 to browser.cache.disk.capacity
- Assign to browser.cache.disk.enable False
- Assign the value 0 to browser.cache.offline.capacity
- Assign to browser.cache.offline.enable False
- Put temporary files in RAM to minimize writes to the SSD:

sudo gedit / etc / fstab

Add to the end of the file:

tmpfs / tmp tmpfs defaults 0 0
tmpfs / var / tmp defaults 0 0 tmpfs
tmpfs / var / log tmpfs defaults 0 0
tmpfs / var / log / apt tmpfs defaults 0 0

register it and then
- Edit / Settings / Advanced / Storage Offline / Use up to "0" MB of disk space for cache.

A Tip:
Place the configuration editor in the Applications menu / System Tools to have easy access to the settings of all parameters:

System / Preferences / Main Menu / System Tools - tick Publisher configurations.

Retractable panels - adjustable speed
The top and bottom panels can be made retractable with: right click in the panel / properties / driver auto-hide. I chose a width of 30 pixels. However the rate of appearance / disappearance is not optimal and it is quickly annoying.
To change this speed:

Applications / System Tools / Editor configurations/apps/panel/toplevels/bottom_panel_screen0/hide_delay

and

/ apps/panel/toplevels/bottom_panel_screen0/unhide_delay

Replace the values of timers for those chosen after test, my choice for 500 ms and 50 ms unhide_delay the hyde_delay.

Touchpad settings :
System / Administration / Synaptic package manager check gsynaptics - apply. Setting TouchPad:

System / Preferences / Touchpad / Scroll adjust the vertical scroll halfway or according to your taste.

Check that horizontal scrolling is checked.

Install the software:
- Applications / Ubuntu repositories or via System / Administration / Synaptics Package Manager

VLC - Cheese - Gparted - Scite - Bluefish - Filezilla - Wine - Adblock for Firefox Extension - Extension No Script plugin for Firefox 6.0 Sun Java - Sun Java Runtime Environment 6

Read protected formats (DVD)
System / Administration / Synaptics Package Manager:

install packages ubuntu-restricted-extras libdvdcss2 and

Also used to play DVDs from a small external drive slim

Configure power management:

System / Preferences / Power Manager

Enter the settings on AC and battery Choose the icon display (Standing for example). Hibernation (suspend to disk) can not operate with a low swap, just the day before being delicate at least on the Dell, I chose to turn off the PC when the battery is critical or the display closed. It is much more efficient. The downtime is 10 s and the starting time of 40 s including wifi so it is not at all annoying and it saves the battery.

Remove applications at startup
System / Preferences / Applications startup - delete:
Visual Aid - Applet queue print - Remote Desktop - GNOME Splash Screen -
Bluetooth Manager - Alarm notification Evolution - Sevice Manager word GNOME password -
Check for new drivers - AT SPI Registry Wizard - Updated user folders

Customize Office :
To install the icon on the desktop - Computer - Home Users - Network Servers - Trash - Volumes visible

Applications / System Tools / Configuration Editor / apps / nautilus / desktop icons check all that visible

Therefore, I delete the trash in the bottom toolbar (right click remove from panel). To install application icons in the toolbars - eg VLC - Cheese - Gimp - Scanner - Calculator - Find files - Set Terminal Applications / Topic / right click on software / add this launcher to the dashboard, and then move Up or ba lock. To add functionality to dashboards: right click in the toolbar, add dash / choose
