Hello,
on my Alienware m15x Notebook I installed debian wheezy (in the 32bit
version with kde).
Hum, knowing that it is an alienware say nothing about the processor
model, so maybe the 32bit choice is not the best one.
I do not know, for now I did not read your full mail.
It is an i3 with 64bit support, I had a 32bit cd here so used it without
thinkink about it.
The system has 5gb ram
Now I have a few questions:
1: When I boot there will be 4 linux entrys with the kernel name. one
ending ...-4-686-pae (or like this) ando one with a 2 as the 4.
Can I delete the entry with the 2 (inclusive the recovery?)
And how can I delete it?
PAE is an extension to expand your maximum RAM above 4G byte of RAM,
which is not possible for motherboards with simple 32 bit support.
However, noawadays, I do not think
there are still new computers without 64 bit support, which include
the ability to support more RAM than old (and when I say old, that's
more than 10 years) computers.
I think you could remove non-pae options. In fact, I'm pretty sure you
could simply move to a 64 bit architecture... but in doubt, just try
to boot on pae, and if everything works correctly, remove the other one.
Both entrys have a pae, my question is: can (and how can) I remove the
...-2-686-pae entry?
2:My Network Manager is not working right.
First the Wlan wasn't working I installed the driver and it worked.
The next day I restarted and nothing worked.
I needed a few time to set up eth0.
Over eth0 I can use Iceweasel and aptitude but the networkmanager
(kde) doesn't accepts the connection. Because of this Pidgin is not
working.
wlan isn't working too.
eth0 and wlan0 are two different things. wlan usually means, wireless,
and wireless have often closed source drivers. So with debian, you
will need to enable them by yourself. Wiki and internet are full of
informations about that, but, in short, enable contrib and non-free
repo in your /etc/apt/sources.list, know your hardware with $lspci or
$lsusb and you should have enough informations to discover what you
need to install.
Eth0 is usually working fine with generic, and free, versions, this is
why it works. If your network manager gives you problem... the
solution I took until now, which is not advised, is to only enable the
kind of network you need.
In few words, this consist about using commands like #ifdown
<eth0/wlan0>, #ifdown <eth0/wlan0> and editing the file named
/etc/network/interfaces.
Of course, this is not an automated solution, but it avoids the use of
any software taking decisions for you.
I set up wlan0 with the iwifi driver it worked fine, but than i shutdown
the laptop and nothing worked anymore. Than I set up eth0 (I can use the
www with iceweasel or aptitude) but wlan0 doesn't works and the network
manager meant I have no connection, I think thats the reason, why pidgin
isn't connecting.
3: shall i reinstall the 64bit version?
If it was working previously, I think yes. 32 bit will only be slower.
I can see no interest of using 32b when you can use 64b. I might be
wrong, so, please, explain me why you switched back to 32B?
I had an cd for wheezy with 32bit here laying around and had used it. I
wasn't thinking about that it is a 32bit verison.
