[Solved] Fedora 15, 14 : Can't login using tty 1~6

From Fedora 14 , its not allowed to login  using tty.
Neither root nor other users can login using tty.
This problem is caused by a file in /etc/udev/rules.d/
So i deleted all the files in that folder.

Dont worry, it wont do any harm, I tested it in my F15
reboot the system

Now you can login using tty.
Some of the deleted files are automatically created after the reboot

Ubuntu 11.10

It seems like Ubuntu dropped Gnome shell and replaced it with Unity. Oneiric Ocelot will be shipped with Unity as default. But they say it will be much more improved.
Also heard a rumor that Fedora 16 will be shipped with unity.
Oneiric Ocelot will be powered using Linux Kernel 3.0 final
Other changes are improved application switcher, smoother compiz grid plugin and software center also got some improvements.

Fedora 16 : Switching from ext3 to Btrfs

There is news that the upcoming Fedora 16 will be shipped with a brand new unstable file system called Btrfs as DEFAULT. The Btrfs is not yet stable according to wikipedia.
But surely it will be a star to the crown of F16 like Gnome 3 of F15. The new FS is rich in features.
No need to worry about the current data in ext3 or ext4 filesystem. They can be easily mounted as Btrfs with write support.
The Btrfs is revolutionary because most of the disk management operations can be done online ie you dont need to unmount a partition to perform a resize or creation of new partition.

Gnome3 Customization | Change Panel Colour n Transparency

The default opaque panel on top of gnome3 is like eating milk n chala curry.
The /usr/share/gnome-shell/theme/panel-border.svg is the main file to be changed to change its appearance.

Now wake the gimp expert in you

open the file /usr/share/gnome-shell/theme/panel-border.svg in gimp

must be root to do it


sudo gimp /usr/share/gnome-shell/theme/panel-border.svg


modify the file as you wish


here i deleted the whole image

ctrl + a
Del


then took the brush tool choose colour black (default)

set Opacity to 52

made the brush image large enough to cover the full image

painted once in the image

then choose orange colour,

set Opacity to 100


painted a line in the bottom, this will appear as the bottom border.

saved it as

panel-border.png

because in gimp does not support saving a file in .svg format.
Also i don't know whether svg can handle alpha channel.

now the pic will look like as shown

Now open up the file /usr/share/gnome-shell/theme/gnome-shell.css


/usr/share/gnome-shell/theme/gnome-shell.css


goto the section

#panel {
    color: #ffffff;
    background-color: black;
    border-image: url("panel-border.png") 1;
    font-size: 8.5pt;
    height: 1.86em;
}


change the line border-image: url("panel-border.svg") 1;

to

border-image: url("panel-border.png") 1;

save the file

reload the gnome3 desktop by hitting

Alt+F2

then enter

r

hit Enter

Gnome3 Customization | Change Alt+Tab color

To change the color or transparency of Alt+tab App switcher in Gnome 3, you need to edit the file "/usr/share/gnome-shell/theme/gnome-sll.css"
You can do much if you know css basics.




Open the file

sudo gedit /usr/share/gnome-shell/theme/gnome-sll.css


go to the section

.switcher-list

use search to find it (ctrl + f)

the line

background: rgba(R,G,B,A);


The R,G,B for rgb values of the colour
Change it by referring here

A stands for alpha channel. use a value from  0.0 to 1.0
0 is transparent.

example :

.switcher-list {
    background: rgba(173,255,47,0.5);
    border: 1px solid brown;
    border-radius: 24px;
    padding: 20px;

    font-size: 9pt;
    color: brown;
}

In the example above i have changed the border colour to brown.

    -shell-grid-item-size: 50px;
}

man FSCK

NAME
       fsck - check and repair a Linux file system

SYNOPSIS
       fsck [-lsAVRTMNP] [-C [fd]] [-t fstype] [filesys...]  [--] [fs-specific-options]

DESCRIPTION
       fsck  is  used to check and optionally repair one or more Linux file systems.  filesys can be a device name (e.g.  /dev/hdc1, /dev/sdb2), a
       mount point (e.g.  /, /usr, /home), or an ext2 label or UUID specifier  (e.g.   UUID=8868abf6-88c5-4a83-98b8-bfc24057f7bd  or  LABEL=root).
       Normally,  the fsck program will try to handle filesystems on different physical disk drives in parallel to reduce the total amount of time
       needed to check all of the filesystems.

       If no filesystems are specified on the command line, and the -A option is not specified, fsck  will  default  to  checking  filesystems  in
       /etc/fstab serially.  This is equivalent to the -As options.

       The exit code returned by fsck is the sum of the following conditions:
            0    - No errors
            1    - File system errors corrected
            2    - System should be rebooted
            4    - File system errors left uncorrected
            8    - Operational error
            16   - Usage or syntax error
            32   - Fsck canceled by user request
            128  - Shared library error
       The exit code returned when multiple file systems are checked is the bit-wise OR of the exit codes for each file system that is checked.

       In  actuality,  fsck  is simply a front-end for the various file system checkers (fsck.fstype) available under Linux.  The file system-spe‐
       cific checker is searched for in /sbin first, then in /etc/fs and /etc, and finally in the directories listed in the PATH environment vari‐
       able.  Please see the file system-specific checker manual pages for further details.

Fedora 15: Switch to KDM

I still can't live avoiding KDE and its KDM.
In fedora 15 default Display Manager when installing both KDE and Gnome is GDM. Gnome3 is near sexy to KDE4 but GDM really sucks.

To switch from default GDM to KDM in fedora 15 do as follow

su -c 'echo "DISPLAYMANAGER=\"KDE\"" >> /etc/sysconfig/desktop'
su -c 'echo "DESKTOP=\"KDE\"" >> /etc/sysconfig/desktop'


You can also try an alternate method by opeing the file /etc/sysconfig/desktop

then add the following lines or make appropriate changes if they exist
DISPLAYMANAGER="KDE"
DESKTOP="KDE"

Plans for greater Unity app integration in Ubuntu 11.10

Ubuntu 11.04 brought with it a shiny new Launcher with shiny new capabilities, such as the ability to display progress bars, count badges and quicklists on application Launcher icons.
Although Ubuntu 11.04 didn’t see the default application take advantage of these features to any great degree plans are afoot to provide Oneiric’s default apps with Unity integration from the get-go.

Default applications

• Gwibber already has Quicklist support in Unity but will benefit from an unread tweet/message count in Ubuntu 11.10.
  
• Update-Manager will receive an update count, progress bar and quicklists containing items such as ‘check for updates’, etc.
  
• Banshee won’t gain player controls in its’ quicklist but ‘media sources’ – as currently found in the Banshee sidebar – will be entered. A progress bar for music and podcast download will also be looked into.
  
• Dynamic quicklists – as seen in AWN and Docky – have been suggested for use with Nautilus, with its quicklist containing user shortcuts and favourites. Progress bars to relay something transfer/copy status are also being mooted.
  Other integration changes planned include control items in Transmission’s Quicklist and progress bars for Brasero – and the Ubuntu Software Centre.

Simple quicklists are also proposed for Gedit, the Terminal, new default backup ‘Deja Dup’ and movie player Totem.

Ubuntu adopts LightDM, login screens to get more exciting..

‘LightDM‘ will replace the standard ‘GDM’ login experience for Ubuntu 11.10, based on a decision taken today at the Ubuntu Developer Summit.

Why?
With Ubuntu 11.10 requiring a slick, ‘consumer orientated’ login experience that better matches the rest of Ubuntu, the decision to switch to ‘LightDM’ proved the ideal solution.
LightDM is promoted as fast, small, well documented, is easily themable and has ‘great accessibility’. A 3D-based interface will greet those with capable hardware, with a 2D version being used fallback where not supported.
Login screens are something that often get overlooked on a machine because at most we spend a few seconds every day staring at them. But they are important not only because of the security they offer, but because of the loading time they can add to a system boot.
Canonical has decided it is going to change the login manager it uses for Ubuntu 11.10 (Oneiric Ocelot) from the Gnome Display Manager (GDM) to the Light Display Manager (LightDM). This is a significant change for two reasons. The first is one of size, and as the name implies LightDM is much more lightweight than GDM. While GDM consists of around 50,000 lines of code, LightDM only has 5,000 for effectively doing the same job. LightDM is meant to be very fast meaning it could have a positive impact on boot times.
