make your filesystem faster

i found a tip to speed up your linux filesystem (ext3 and reiserfs) here and here.

To get more infos about this tweak, look at the links above.

You have to do the following steps: (note: you have to change the partition to your needs. In my case its: "/dev/sda8 /")

1) edit your /etc/fstab and add thing marked bold to your mount line.
/dev/sda8 / ext3 defaults,noatime,nodiratime,errors=remount-ro,data=writeback 0 1

2) edit /boot/brub/menu.lst and add the bold marked entry.
kernel /boot/vmlinuz26 root=/dev/sda8 ro vga=865 rootflags=data=writeback

3) it can be necessary to run update-grub after that. But its not necessary on my archlinux system.

4) To prefent errors add the new mode to your filesystem before reboot.
tune2fs -o journal_data_writeback /dev/sda8

5) to see if the changes went right, check it with:
tune2fs -l /dev/sda8
(you should do this again after reboot)

have fun with a faster performing system. ;)

speed up your archlinux system

Found this post with some tips to optimize your archlinux system:
http://tuxtraining.com/2009/09/04/optimize-pacman-and-free-space-on-arch

In short:

pacman -Sc This clears outdated/uninstalled packages.

pacman -Scc This clears the whole folder, not just the packages that are outdated/uninstalled.

pacman-optimize && sync optimizing the archlinux database

Browser independent mouse gestures

In kde4 its possible to define desktop wide mouse gestures.
Here is a file to include in systemsettings to get mousegestures in chrome and most other browsers.

(This is a modified version of the script without firefox support cause in firefox i use a extra extension for mousegestures. There are also some more gestures then in the original script)

The original Skript can be found here: Link There is also a more detailed description, what browsers are supported.

Customize console resolution

You can change you console resolution:

Install "lrmi" using you paketmanager.
After that you can get a list of all available resolutions supported by your graphichardware by using: "vbetest" in a console that already uses framebuffer.

You get a list similar to this one:

[356] 1440x900 (256 color palette)
[357] 1440x900 (8:8:8)

Note the number before your preferred resolution (357 in my example).
Add 512 to this number (357 + 512 = 869).

After that open /boot/grub/menu.lst and change the line from your kernel from something like this:

kernel /boot/vmlinuz26 root=/dev/sda8 ro

to

kernel /boot/vmlinuz26 root=/dev/sda8 ro vga=869

Thats it. After restarting your system you get the new resolution in your console session.

Starting multiple firefox instances at the same time

With a little hack its possible to start more then one firefox instance at the same time. It is also possible to start different versions and using different profiles.

you have to set a variable. That's all:

export MOZ_NO_REMOTE=1 && firefox -Profilemanager && export MOZ_NO_REMOTE=0

Firefox performance tip: Shorter history

you can limit your history size in firefox to get better performance.

Go to:

Preferences > Privacy > History

and set the option: "Keep my history for.." to 5 days.
