Черный экран видео с Beryl 'om

Чтоб можно было нормально смотреть видео при этом не выключая берила:

Gstreamer

That’s the default Ubuntu player, used by Totem. To correctly visualize you video files with Totem proceed as follows:

1) Open a terminal and enter:

gstreamer-properties

2) Move to the video tag.
3) In default video plugin select “X Window System (without Xv)”.
4) Click on try to verify if it works fine.
5) Close this window, problems solved.

Vlc

That’s my preferred player, I always use it and surely many of you do too. It is very important to have it working correctly, so:

1) Run vlc.
2) Settings –> Preferences.
3) Selct video and then outpoot modules.
3) Check the little “Advanced options” check box on the button left corner of this window.
4) New options will now appear, so in video outpoot choose “X11 video out”.
5) Save and exit. Mission completed.
Mplayer

I never use it and every time I try to open something with it, it never works ;P but if you use it…:

1) Run Mplayer.
2) Right click on the screen and select Preferences.
3) Select the video tag and in available drivers choose X11 (XImage/Shm).
4) Save and restart the application.

Xine

Very useful if you use Kaffeine or Totem with xine:

1) Run xine.
2) File –> configure –> preferences.
3) In experience_level select “Master Of The Known Universe” so that all the setting become visible.
4) Select the video tag.
5) In driver choose “xshm”.
6) Restart Xine.

Куча нюансов

В линуксе с Си куча проблем оказывается, надо заботится буквально о каждой мелочи.

Чтобы правельно считать нескольно отдельных строчек с пробелами:

scanf(" %[^\n]",answer);
scanf(" %[^\n]",answer);

обязательно пробел до экспрешона, а то этот сканф сожрет
предыдущий ентер из stdin'a и будет доволен...
fflush(stdin) чего то не помогает ...

Вместо stricmp в линухе функция для сравнения без учета регистров strcasecmp();
инклуд: strings.h

Some bash scripts.

Make your console nicer and more useful:

user-) cd Download/
WD=/home/user/Download
user-Download-)

Insert this code to .bashrc file in your home folder:

function SetPS1()
{
local HostBit=""
if test "$OS" = "Linux"
then
if test "`who|grep "$USER"|grep \"tty[1-6]\"`" = ""
then
HostBit="@\h"
fi
fi
local DirBit="-\W"
test "`pwd`" = "$HOME" && DirBit=""
case "$TERM" in
xterm|linux) PS1="\[\]\u\[\]$HostBit\[\]$DirBit\[\]-) " ;;
*) PS1="\u$HostBit$DirBit-) " ;;
esac
}

SetPS1

thcd()
{
builtin cd "$@"
if test -t 1
then
case $TERM in
xterm) echo "WD=`pwd`" >&2
echo -n "]0;XT `basename \"\`pwd\`\"`" >&2 ;;
*) echo "WD=`pwd`" >&2 ;;
esac
fi
SetPS1
}
alias cd='thcd'

tput - change cursor location, colour, text format.


Change last entered command:

$:man bash
$:^ba^c ( that will give - man csh )

Changing default shell:
/etc/passwd holds starting shells for each user on machine.

Auto Mounting:
/etc/fstab holds all devices that should be mounted automatically.

/dev/sda3 /win ntfs defaults 0 0

Script commands:
enable - execute program
source - include other file to current script


Switching workspace in command line:

GNOME DESKTOP

• [ program wmctrl needed ] ( yum install wmctrl )
  
• wmctrl -s desktopNum

Restoring GRUB loader:

Restoring GRUB:

• Boot from live CD(say knoppix)
• mount /dev/sda1 /media/sda1
  (mount system)
• chroot /media/sda1
• grub-install /dev/sda
  ( or /dev/sdaNUM, where NUM is partition )

OR

• mount /dev/sda1 /
  (mount system)
• grub
  ( opens grub terminal )
• find /boot/grub/stage1
  ( shows partitions where grub is installed )
• root (hd0,partNum)
  ( partNum you can get from previous command, hd0 - means first hard disk, hd1 will be second.. )
• setup (hd0)
  ( if grub has to be installed to MBR. Or [ setup (hd0,partNum) ] - installs GRUB to linux root partition)
