linux • fedora • ssd

A collection of Fedora 20 optimisations for my current setup (the SSD in a OCZ Vertez 3 120Go). Notice that most of my tweaks come from fedy, an excellent open source tool that does pretty much everything needed to get a more user friendly OS.

SSD Optimisations

From fedoraproject.org

Add the following lines to /etc/fstab

#SSD optimization,  /tmp to RAM 
none             /tmp/                   tmpfs   size=10%                 0       0

=====

From debian.org

Add the “noatime” (or “relatime”) mount option in /etc/fstab, to disable (or significantly reduce) disk writes whenever a file is read.

To support discards with lvm, go modify your /etc/lvm/lvm.conf and enable issue_discards:

devices {
...
    # 1 enables; 0 disables.
    #issue_discards = 0
    issue_discards = 1
}

=====

From ArchLinux

Modifiy Mount flags to support discard and relatime :

/dev/mapper/fedora_hp--envy-root /                       ext4    defaults,relatime,discard        1 1
UUID=a8c8c6c9-7377-4ae7-860b-d2727cae704b /boot                   ext4    defaults,discard        1 2
/dev/mapper/fedora_hp--envy-home /home                   ext4    defaults,relatime,discard        1 2
/dev/mapper/fedora_hp--envy-swap swap                    swap    defaults,discard        0 0

=====

Prevent sleep on lid closed

$ vi /etc/systemd/logind.conf

change

HandleLidSwitch=suspend

to

HandleLidSwitch=ignore

then restart the login service:

$ systemctl restart systemd-logind.service

Try closing the lid of the laptop and check it does not suspend.

=====

GRUB Timeout

When your system boots, you’ll see the GRUB menu, or if you’ve enabled the menu to show by default. The GRUB menu is displayed for a predetermined number of seconds. However, on Fedora, the default timeout is only 5 seconds. So you may want to change this timeout.

  • Backup the /etc/default/grub file.
cp  -v  /etc/default/grub  /etc/default/grub.bak
  • As the root user, open up the /etc/default/grub file in your favorite text editor:
	vi   /etc/default/grub

  • Now, edit the “GRUB_TIMEOUT” line. You will then have to regenerate the GRUB settings from the file.

  • In terminal, run the following command to generate settings from /etc/default/grub file.

	grub2-mkconfig  -o  /boot/grub2/grub.cfg
  • Reboot and enjoy.

Blackberry Dev

From e-bluesoft.com:

Sometimes, after installing on Fedora, LPCExpresso does not start. The error shown is

java.lang.UnsatisfiedLinkError: Could not load SWT library. Reasons: 
        /usr/local/lpcxpresso_5.2.4_2122/lpcxpresso/configuration/org.eclipse.osgi/bundles/214/1/.cp/libswt-pi-gtk-4236.so: libgtk-x11-2.0.so.0: cannot open shared object file: No such file or directory
        no swt-pi-gtk in java.library.path
        /home/laji/.swt/lib/linux/x86/libswt-pi-gtk-4236.so: libgtk-x11-2.0.so.0: cannot open shared object file: No such file or directory
        Can't load library: /home/laji/.swt/lib/linux/x86/libswt-pi-gtk.so

To solve this dependency problem, gtk-engines for linux32 has to be installed on the system, with the command:

$ yum install gtk2-engines.i686

Now LPCXpresso starts without any error.

Gedit

Failed to load module ‘pk-gtk-module’

From mindthatbus.blogspot.fr

When running gedit from a terminal I always got a message Failed to load module ‘pk-gtk-module’ but gedit seemed to start normally. to fix it on Fedora 18 with Gnome3, I did the following steps:

$ yum remove PackageKit-gtk-module
$ yum install PackageKit-gtk3-module

From the source:

If you’re interested, these packages load fonts needed to display documents in other languages.

Failed to load module ‘canberra-gtk-module’

From fedoraforum.org

$ yum install libcanberra-gtk2.i686
