Linux em Dias

If you dual boot Windows and Ubuntu or any other Linux distribution, you might have noticed a time difference between the two operating systems. When you use Linux, it shows the correct time. But when you boot into Windows, it shows the wrong time. Sometimes, it is the opposite and Linux shows the wrong time and Windows has the correct time. That’s strange specially because you are connected to the internet and your date and time is set to be used automatically. Don’t worry! You are not the only one to face this issue. You can fix it by using the following command in the Linux terminal: sudo timedatectl set-timezone America/Sao_Paulo If your timezone is not the Brazilian one, you can use:  timedatectl list-timezones timedatectl set-local-rtc 1 Again, don’t worry. I’ll explain in detail how the above command fixes the wrong time issue in Windows after dual boot. But before that, let me tell you why you encounter a time difference in a dual boot setup. Why Windows and Linux show diff...

If you enable auto log-in in Ubuntu 11.10 Oneiric, it automatically logs into Unity. Some people installed gnome-shell Gnome 3 desktop and want Ubuntu auto log into gnome-shell. Normally, we first disable auto log-in behavior, log out and back into gnome-shell, and finally in Gnome 3 desktop enable auto log-in again. Unfortunately, this settings doesn’t work for me, but I found a command-line solution (from Ubuntu forum): To make Ubuntu 11.10 auto log-in gnome-shell, open up a terminal window and run this command:   sudo /usr/lib/lightdm/lightdm-set-defaults -s gnome-shell If you want to change back to Unity, run:   sudo /usr/lib/lightdm/lightdm-set-defaults -s ubuntu BTW: to auto log-in gnome classic desktop ( sudo apt-get install gnome-session-fallback ), run:   sudo /usr/lib/lightdm/lightdm-set-defaults -s gnome-classic

1.  Open a  elevated command prompt  or a  command prompt at boot . NOTE:   If you have a  RAID  setup or a  PCI-E SSD  as your boot drive and want to open a command  prompt  at boot, then you may need to use the  Load  Drivers  option in the  System Recovery Options  screen to load it's  drivers  first before Windows will see the boot drive to be able to use the bcdedit command on it . 2.  In the elevated command prompt, type  bcdedit  and press enter. (see  screenshot  below) NOTE:   This will let you see what the  description  (name) and  identifier  of the operating system(s) listed in Windows Boot Manager are under the  Windows  Boot  Loader  section(s). For example,  Windows 7  (description) as  {current}  (identifier).   3.  In the elevated command prompt, type the command below for a listed ...

Ubuntu 11.10 Fix: How to Add the Classic Desktop and Gnome 3 Shell As Login Options After updating your system, if isn updated yet, the first thing to do is to press CTRL+ALT+, when doing that your terminal screen will appear, with that open type:   sudo apt-get install gnome-shell   then,    sudo apt-get install gnome-session-fallback Once installed, you should be able to just log out and log back in to one of your new desktops, but if not, then do a reboot. Then you can log into Gnome Shell at the login screen by choosing “ GNOME “, or the more familiar legacy desktop by choosing “ GNOME Classic ” (or “ GNOME Classic (No Effects) ” for less powerful computers or graphics card issues). If you can’t find where to log into other environments, it’s always a hidden menu you need to access, previously by the word Options at the bottom of the screen, but in 11.10 is a gear icon near the user name; in following versions, that will no doubt change, but j...
