Na upravu neprijemneho blikania monitora

display flickering problem solved :)

So my solution is, which seems to work well on my system:

1. I opened up Startup Applications

2. I clicked Add

3. I typed a name and the following in the command field:

   xrandr -s 1280x1024 -r 75

Using this xrandr -s 1280x1024 -r 75 is run at every sytem startup and sets the refresh rate as required. There could be a better option but right now this seems to be OK for me.

Hopefully the LTS will fix the showstopper bug of no easy, gui way to change the refresh rate.

or in terminal simply>>>>>> xrandr -s 1280x1024 -r 75

Change Windows Domain password from Linux

 If you use Linux in a Windows domain and there are N days to expiry, this is how you can change it without resorting to a windows machine.

smbpasswd -r <domain-server> -U <user name>

Re: mount: only root can mount --- What the hell is this?

sudo mkdir /media/drive
sudo mount /dev/sdb1/ /media/drive

or

sudo mount /dev/sdb1/ /media/SEGATE SAT

Check by typing

Code: sudo fdisk -l

tak jednoducho:

list existujucich jadier:

dpkg --list | grep linux-image

potom odstranit pozadovane jadro:

sudo apt-get purge [jadro zo zonamu]*
