unknown CPU in Ubuntu

[HiME]

my computer has a PII 450MHz processor on it but Ubuntu reports unknown for it,

here's what my CPU supposed to be:

CPU Properties:
> CPU Type Intel Pentium II
> CPU Alias Deschutes, A80523
> CPU Stepping dB0
> CPUID Revision 00000652h
>
> CPU Speed:
> CPU Clock 448.01 MHz
> CPU Multiplier 4.5x
> CPU FSB 99.56 MHz
>(original: 100 MHz)
> Memory Bus 99.56 MHz

it's a very huge problem because everything is running very slow in Ubuntu,
Some other problems are the creative sound cards, logitech webcam, matrox video card are not being recognized fully.

Another question is how do i communicate Ubuntu with my windows workgoup to share files? i'm planning on doing some reaserch on that area after i'm done with all the drivers support

I don't know too much about your compatibility problems, but I can tell you that the software that you want to share files is samba.

Where does ubuntu report unknown for it and how do you know that's the cause of your slowdown?

 

[HiME]

i clicked on:

System -> Administration -> Device Manager -> Processor

Vendor: unknown
device: unknown
status: status
bus type:unknown
device type: processor
capabilities: processor

my CPU usage had been hanging at 7% while idle
swinging the mouse around the screen will offer me 60%
everything is slow compared with windows..where menus and clicks will have .5 second of delay

more info.
p2 450
256MB ram
matrox video card 32MB

My eMachine PII with Celeron 533MHz works fine with Ubuntu. Yes, its slower than my FC4 rig (AMD 3500+) but that's to be expected. I use it primarily for surfing the web and simple documentation. Just wanted to utilize Ubuntu's features and it was a very easy install. All hardware drivers were an easy find.

 

[bersl2]

What are the contents of the file /proc/cpuinfo?

 

[Nothinman]

Your X setup is probably the culprit, most things don't care about the capabilities of the CPU, they just run.

If you run 'grep Driver /etc/X11/xorg.conf' I bet you'll see a line that says 'Driver vesa' or similar, meaning you're using the vesa driver instead of the mga driver.

processor: 0
vendor_id: GenuineIntel
cpu family : 6
model: 5
model name: Pentium II (Deschutes)
stepping: 2
cpu MHz: 448.107
cache size: 512 KB
fdiv_bug: no
hlt_bug: no
f00f_bug: no
coma_bug: no
fpu: yes
fpu_exception: yes

If this report shows that it recognizes the CPU, then what is the problem? Videos that could be played in XP smoothly cannot be played in Ubuntu, CPU usage is extrememly high while compared. The installation is new and i'd only installed java runtime, upgdated firefox and a couple of other things. I had just switch to ubuntu 2 days ago and the speed in Ubuntu is really unacceptable.

You should try to install the matrox drivers for your video card. That should help out.

 

[HiME]

oh yeah, i also got stuck on the video card

first i downloaded mgadriver-x86-4.3.0.tar.gz
then i extracted it into matrox_driver-x86-4.3.0, which contains several files with install.sh
then i ran sh install.sh

here comes the error Error: you must be logged in as Root to run this program

isn't that i'm the root?? i'm the user who had been created during the installation of Ubuntu


ftp://ftp.matrox.com/pub/mga/archive/linux/2005/readme_mgadriver_4_3.txt

here's a link, i don't know if i'm missing anything here..

 

[n0cmonkey]

Try sudo sd install.sh

You need to be the root user to install stuff like that.

 

[Nothinman]

Do you really need the driver from Matrox? I have a Matrox card in my Alpha and when I had X on it the driver that comes with X worked just fine.

 

[P0ldy]

Using something other than Gnome or KDE will improve your playback quality, probably. Try Fluxbox or Xfce if you want a GUI on that box.

 

[HiME]

after typing in: sudo sh install.sh , it worked!! After a restart everything became faster but the CPU usage is still very high, Videos aren't playable yet, i'll try and seek for some codecs for them. The installation of the video driver had definitely helped to increase the performance.

as i try to get a log from the Xoutput by typing : startx >& Xoutput.log
nothing happens here, Where could the log file be??

the paper says:
Take note of the "BusID" lines. You need to edit these to
match the BusID output shown in your Xfree86 log file. You can
create a log file by redirecting the X output to a text file:
startx >& Xoutput.log


after that i decided to jump over to enable the mlti display mode
typing: startx -- +xinerama

it says
xauth: creating new authority file /home/HiME/.serverauth.8298
x: user not authorized to run the X server, aborting
Couldnt get a file descriptor referring to the console



I had discovered that Ubuntu won't let me to eject the CD using the button on the drive. I must go all the way to the desktop, right click and press eject for the CD. The button is disabled whenever a CD is inside it..

 

[HiME]

sorry, i just found the log file at the /home/, but it gets the same error as the second command from the last post

X: user not authorized to run the X server, aborting.
Couldnt get a file descriptor referring to the console


after i disabled the sound events, the system became even faster..

I've never needed it for my matrox cards.

Like you probably know, the top command can show you what is running and taking up CPU time.

startx > ~/Xoutput.log 2>&1

You probably have to unmount the cd first.

Doubtful, they'll definitely use more memory but unless something is really wrong they won't use any CPU when idle so the video player should have almost all of the CPU to itself no matter what WM is running.

 

[gizbug]

had too many headaches with ubuntu, thats why its off the system

 

[TanisHalfElven]

please tell us the output of.
sudo cat /proc/cpu (just tab into the /proc and look for somerthing like cpu or cpuinfo... i am not on linux right now to check)

also perhaps ubuntu is slow cuz your gfx is not accelerated and you need to install the drivers for it. also try using flux box cuz its muich lighter than gnome and consumes much less ram .


how much ram do you have. if its not alteast 128 (256 is better) try using dsl (damn small linux) and check if you like its performance.

 

[Nothinman]

sudo cat /proc/cpu (just tab into the /proc and look for somerthing like cpu or cpuinfo... i am not on linux right now to check)

A) He already did that.
B) sudo isn't necessary, the file is world readable.

also perhaps ubuntu is slow cuz your gfx is not accelerated and you need to install the drivers for it.

The text file he linked to about the Matrox driver says they're just a modified version of the OSS mga driver and you only need them if you want to use the other features of the card like the dual-head stuff. I haven't personally used them, but I would bet that normal use performance is the same.

 

[HiME]

After I'd installed the driver, I am now trying to enable the duel head function


I need Xoutput.log for the PCI BusID, but the log gave me,

X: warning; process set to priority -1 instead of requested priority 0
Fatal server error:
Server is already active for display 0
If this server is no longer running, remove /tmp/.X0-lock
and start again.

After entering this command my system will refuse to open anything, such as firefox, documents, or any applications. I'll have to restart the OS.



Second problem is the installation note tells me that I?ll need to modify "XF86Config" under /etc/X11/, but I couldn't find that file!! I found xorg.conf instead which contains the same thing as what XF86Config is supposed to have, but the xorg.conf won't allow me to do modifications.

Hope the installation notes will help:

You didn't try to start X while in X did you?

Check /var/log/Xsomething_or_other.log.

xorg.conf is the file you want. Why can't you do the modifications?

 

[yuchai]

Which application are you using for DVD play back? Check to see what kind of video output you're using. For optimal performance, use the "xv" video output.

 

[HiME]

Thank you so much, I have the file Xorg.0.log and xorg.conf in my hands now

I can't do modifications to both files because it says read only, i tried system ->admin -> loginscreensetup ->security, and enabled "allow root to login with GDM" but it still didn't work. Am i missing something here?

Inside the file properties it says only the owner, which is the root, could make changes to those two files.
