Linux Tips

Use profiling to speed up boot. By using profile, a profile of your boot is kept to make your next boot faster. After a couple of boots, a better profile would be ready for your machine. Follow the steps below for that: 1. Edit your grub $ sudo gedit /etc/default/grub You can find the lines GRUB_DEFAULT=0 GRUB_HIDDEN_TIMEOUT=0 GRUB_HIDDEN_TIMEOUT_QUIET=true GRUB_TIMEOUT=0 GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian` GRUB_CMDLINE_LINUX_DEFAULT=" quiet profile " GRUB_CMDLINE_LINUX=""   add profile to the line GRUB_CMDLINE_LINUX_DEFAULT="quiet" as shown above. 2. Now Update your grub2. Type this in your terminal sudo update-grub2 3. Reboot. 4. Now edit the grub once again and remove the word profile that we added. Update grub ( sudo update-grub2 ) and then reboot.

You can face this issue in two conditions. 1. Those who have installed ubuntu 10.04 might encountered this problem. The screen goes blank just after grub (may be after bios startup, if grub timeout early). Please follow the steps below to fix it. Press e on getting the GRUB bootloader(if not getting grub, press and hold shift key to get grub). Go to the line which says 'quiet and splash', delete these words and type in one of the option from below in their place. The suggested options that I have found are hardware specific. Here is a list: Older Intel video card: i915.modeset=1 or i915.modeset=0 nVidia: nomodeset Generic: xforcevesa Now press Ctrl + X to boot Now login to your Ubuntu as usual. If you have a Nvidia graphics card, this may be the issue with it, Now goto System->Administration->Hardware drivers, and select and activate the nvidia current driver if you have an nvidia card. The driver will be downloaded and activated automatically, and you wil...

Some people, after installing Ubuntu Linux, see the decision of the startup screen (boot GUI) is not appropriate for the resolution of the monitor set in the system. Here I'll show you a way to correct the usplash resolution to match the set in the system. 1. Open a terminal and type: sudo gedit /etc/usplash.conf The sudo command will ask for your password so you can edit the file with administrator permissions. Usplash.conf to open the file you'll see something like this: # Configuration file Usplash # These parameters will only apply after running update-initramfs. Xres = 640 Yres = 480 Or maybe just: # Configuration file Usplash # These parameters will only apply after running update-initramfs. 2. Sets Xres and Yres the resolution you want, for example 1024 × 768. # Configuration file Usplash # These parameters will only apply after running update-initramfs. Xres = 1024 Yres = 768 And save your changes. 3. Now you must update your initramfs for the cha...

If you’ve used Ubuntu Linux for longer than a month, you’ve no doubt realized that every 30 times you boot up you are forced to run a filesystem check. This filesystem check is necessary in order to keep your filesystem healthy. Some people advise turning the check off completely, but that is generally not a recommended solution. Another solution is to increase the number of maximum mounts from 30 to some larger number like 100. That way it’s about 3 times less annoying. But this solution is also not recommended. Enter AutoFsck. AutoFsck is a set of scripts that replaces the file system check script that comes shipped with Ubuntu. The difference is that AutoFsck doesn’t ruin your day if you are so unfortunate to encounter the 30th mount. The most important difference is that AutoFsck does its dirty work when you shut your computer down, not during boot when you need your computer the most! The 30th time you mount your filesystem, AutoFsck will wait until you shut down your computer....
