Right now I found that the traditional partition method do not work
for the new system, like partition manager. So the only way is to
change it into some other software. Gparted seems to be a very good
solution, and it is a free software

support
which
is
worth
checking
out
(an
example here)
Simply
put,
press
down Alt+Shift instead
of
just Shift while
making
selections
to
invoke
column
mode.
One
important
limitation
is
that
the
edits
in
column
mode
are
(as
yet)
not
undo-able.
To
achieve
the
same
with
the
mouse,
hold
down Ctrl while
selecting.

Install wireless card
to my laptop:
My laptop can not
install ubuntu 11.04 due to some issues. So I downgraded into 10.04.
however, this edition doesn't come up with the Wifi driver. So I have
to find it out. Then the big problem comes. The first thing is that
installing the package requires installing building-essential, but I
can not install the building-essential package individually because
it is dependent on some other software. There are several ways to
obtain that 1. setup your own repository.
2. using installing disc. 3. using
I can only choose the
second.
The file is

solve
the slow
scrollI
know
this
topic
is
outdated,
but
the
problem
still
exists
and
I
found
the
answer:
The
module-init-tools
package
installs
the /etc/modprobe.d/blacklist-framebuffer.conf file,
in
which
it
blacklists
all
the
console
framebuffer
modules.
For
some
reason
the vga16fb module
is
not
on
the
list,
and
(at
least
for
me)
it
is
loaded
during
startup
and
causes
the
slow
scrolling.
Try
to
blacklist
it
and
reboot!

install
invidia
driver
if you
have a
computer
with
invidia
driver, you
have to
use
additional
drivers in
ubuntu app
to install
drivers.
However,
people say
the
repository
is old.
Therefore,
you can
also add
the
following
commands to
install the
newest
$
sudo
add-apt-repository
ppa:ubuntu-x-swat/x-updates
$
sudo
apt-get
update
$
sudo
apt-get
upgrade
then you
will get
the newest
version of
nvidia
driver
after
that you
need to
pop in
the app
Nvidia x
server
settings to
activate
the second
screen.
This is
mosly
needed if
you have
two video
card. Then
you have
to save
the
settings
back into
a file
rather than
excute it
directly.
This is
the
difference
between
windows and
ubuntu
because in
ubuntu you
have to
save the
settings in
a file
and then
you can
reload
after
reboot.
For the
rotating,
you have
to add
one line
in
Section
"Device"
Identifier
"Device1"
Driver
"nvidia"
VendorName
"NVIDIA
Corporation"
BoardName
"Quadro
FX 580"

$

install
matlab
2012a
there is
one thing
you have
to be
aware of,
which is
that
'glnxa64' means linux 64 bit, so you have to extract
'matlab_R2012a_glnxa64_installer.zip' file, then you could see
install is a excutable file.
Also add alias
matlab='/usr/local/MATLAB/R2012a/bin/matlab' in
.bashrc to activate shortcut input, then use $
. ~/.bashrc to reload bash file without
rebooting.
installing
the video card driver to Toshiba laptop.
It is not always correct to install all the drivers from
suggestions given by the app 'additional drivers', althrough this
method works quite well for the Video card of T550 (choose 'NVIDIA
accelerated graphics driver (version current) [recommended]'), this
method doesn't apply to the video card of toshiba laptop. From forum
it says that usually the suggestion from additional drivers is quite
old because the repository is not updating to the newest driver.sfdf
permanently mount a
local drive
$
sudo blkid
#use this command to find out the UUID
$
gksudo
gedit
/etc/fstab
then add
this line
UUID=<uuid> /place/to/mount ext4 defaults 0 2
where <uuid> is the UUID we copied from the blkid command.
/place/to/mount is the mount directory. ext4 is the filesystem
then you
can reload the fstab file by
$
sudo

internet even if it appears to be connected. and there is no linux

$ lspci -v
$ lspci -nn
and I found the driver I am using is ath9k. So I downloaded the new
driver (compat-wireless-3.4-rc3-1.tar.bz2 )
after extracting it, using
$ ./scripts/driver-select ath9k
$ sudo make install
$sudo make unload
then it works perfectly.
