Ubuntu _Re_Installation Prob

[Pathik]

Guys, I had installed Ubuntu 7.10 the time it had released but had to remove it cos of space problems.
Now today i tried to install it again.
But the system didn't even boot up from the Live cd. It hanged at the Ubuntu loading screen.
So i removed my GPU and tried installing it on my Integrated Intel Extreme graphics. It worked and the distro got installed.
Now i shut down, inserted my GPU again (Nvidia FX5200 128mb) and tried to boot. But after booting into Ubuntu it gives me a Monitor : Out of Operating Frequency Error. I have a 15" LG CRT.
Any ideas?
Thanks.

This is weird though.. I didn't have any problem with fx5700..

OK Follow this it should work
1) Boot in Single User Mode, as ubuntu calls it, Recovery Mode
2) Run

sudo dpkg-reconfigure xserver-xorg

3) Select simple detection of monitor and select 15" from that
4) For graphics card select vesa
5) For resolution select 1024x768 as max.
6) For colour depth select 16
7) Let the rest be at default unless you know for sure that it's different than what is being detected.
8) Now let it save the configuration to /etc/X11/xorg.conf
9) type

 init 2

10) Now you'll be in regular mode with GUI and all
11) Login to your desktop and open System => Administration => Restricted Drivers Manager and let it download Nvidia driver off the net.
12) One that is finished install nvidia-xconfig then run it
13) Also, for precaution repeat step 2 and this time select nvidia driver with 1024x768 resolution and 24bit depth.

Thanks for the link amitava..
and Mehul when i try to boot even in recovery mode with my gfx card plugged in, it just hangs at the console.
And if i try to configure xorg.conf with my Integrated gfx, then it gives the same Frequency error when i plug in my GPU.
Any other ideas?
Thanks a lot BTW.

Can you post the content of your /etc/X11/xorg.conf here? Especially this part

Mine looks like

Section "Device"
Identifier "nVidia Corporation G73GL [Quadro FX 560]"
Driver "nvidia"
Busid "PCI:1:0:0"
Option "AddARGBVisuals" "True"
Option "AddARGBGLXVisuals" "True"
Option "NoLogo" "True"
EndSection

Section "Monitor"
Identifier "Generic Monitor"
Option "DPMS"
Horizsync 30-70
Vertrefresh 50-160
EndSection

Section "Screen"
Identifier "Default Screen"
Device "nVidia Corporation G73GL [Quadro FX 560]"
Monitor "Generic Monitor"
Defaultdepth 24

And also resolution info if any.

Generally if dpkg is not working as a solution, you need to manually edit xorg.conf using vi. The same which mehul has said above, .i,e, put "Driver" as vesa, Defaultdepth as "16" and Resolution as "1024x768".

After editing and saving, turn off, connect 5200, boot into Ubuntu and then install Restricted Nvidia Drivers.

NOTE: If you don't know OR not comfortable with using vi, then attach you xorg.conf here, I'll edit it and post it back.

amn: vi not actually needed, since you got a live cd, boot from that, edit xorg.conf(using any text editor) as root and continue with the steps. else goto NOTE.

[praka123]

^Vi were the norm.now nano is there,which is default and easy for n00b's.

@pathik:nvidia open source driver "nv" supports that card.use "nv" driver when doing a "sudo dpkg-reconfigure xserver-xorg"

[debsuvra]

I think there are some problems with newer linux distros to detect and configure AGP cards properly. I also have a nVidia FX 5200 and did have the problems pathik faced.

I created a solution and posted here ago, check that @ Howto : Bypass AGP graphics card problem with newer linux distros

I think it will work

@hitboxx
Mine is

Section "Device"
Identifier "Nvidia 5200"
Driver "vesa"
BusID "PCI:0:2:0"
Option "UseFBDev" "true"
EndSection


Section "Monitor"
Identifier "505E"
Option "DPMS"
HorizSync 30-54
VertRefresh 50-85
EndSection


Section "Screen"
Identifier "Default Screen"
Device "Nvidia 5200"
Monitor "505E"
DefaultDepth 16
SubSection "Display"
Modes "1024x768" "800x600" "640x480"
EndSubSection
EndSection

I think that is correct
I hav tried every combination of resos and color depth but it just operates out of frequency.
My frequency limits are HF : 30-54 and VF: 50-80/120.
But Ubuntu is hell bent on running it at HF : 64khz VF : 60hz.
is there any way i can force it to lower the horiz_freq below 54 khz.

@Praka. K i ll try that too.

@Debsuvra ll check it out. thanks.

I ll try out the driver part as "nv" and "nvidia"
BTW hitboxx did ur video driver in use become nvidia after u installed the nvidia drivers thru apt?

[Hitboxx]

Yes, by default, it was "nv", upon installing the restricted drivers it became "nvidia".

[Pathik]

Arey vo sab thik hai. Answer my other queries.

[Hitboxx]

Try putting HF:30-70, I know it sounds absurd, but let it read 70 and also put the driver as "nv". (5200 should be connected)

If it doesn't work, remove all modes except "800x600" and try with vesa as well as nv. It should work.

[Pathik]

i was thinkin the same but i think it wouldnt be safe to operate the monitor at a higher frequency.
and i tried all the combos of resos and even each single resolution but didnt work.

[Pathik]

EDIT: Nothing is working. Getting the same error.

[gary4gar]

try booting into VESA mode

[Hitboxx]

Then stop trying Ubuntu, try with some other distro like Mint.

[praka123]

@Pathik:
First,your vertical freq set for LG 505E monitor was inadequate;

Now,as you have completed installation with onboard Intel graphics and put nvidia agp card inside,u may need to blacklist the onboard intel modules.


I agree that this is a serious unnoticed bug in Ubuntu

So,If you can follow below howto,try and reply here:
boot with "vesa" gfx driver to Ubuntu desktop.complete your restricted driver installation from "Restricted drive manager".

Now,backup ur old /etc/X11/xorg.conf.open a terminal and run:

sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf.bked

now in terminal,

sudo gedit /etc/X11/xorg.conf

enter below xorg.conf details.

^Edit your /etc/X11/xorg.conf to look like above;save and exit.,PLEASE NOTE THE BUSID and VERTICAL FREQUENCY ENTRIES,also the loadmodule entry "DRI" is removed>it seems your onboard graphics is popping up creating problems .so use the ugly hack i mentioned somewhere else :
open terminal and do as below:

sudo gedit /etc/modprobe.d/00local

add the following entries:

install intel_agp /bin/true

save and exit.restart your computer and see whether X loads?

Now,Open synaptic manager=>browse to status>installed .
now remove all xserver-xorg-video-* and xserver-xorg-video-all except xserver-xorg-video-vesa.

select "completely remove and purge option" to remove these unwanted drivers off ur hdd.



lastly,
IMPORTANT STEP:
boot into BIOS of ur comptuer.check and make sure onboard graphics is disabled and/OR select external Agp.

Also,the above xorg.conf is meant to give you a 800x600@85Hz which is,the maximum freq and effect available for a 15" monitor.

the vertical frequency source for LG 505E is:
http://www.ebuyer.co.za/product/LG-1...s-Monitor.html
^so dont panic if it is wrong freqeuncy I,myself got a samtron 56V 15" with same freq.the best resolution available is 800x600@85Hz.


post your results.also if some problem occurs,post the output from terminal for "lspci and lsmod" commands Best of Luck!

[debsuvra]

I think my procedure is easier than the praka123. No matter, great tut though

[gary4gar]

strange, its only you with troubles, it works fine for everyone else
i sure you must have messed up something

[praka123]

@debsurva:in my experiance,simple blacklisting will not work all the times reg modules.

Could as well be a b0rked mobo.
Pathik, What mobo is it? Some intel 845 chipset based, right?

[debsuvra]

If it is a AsRock MoBo, then it can be troublesome. I think AsRock has a AGI instead of AGP that creates the trouble for AGP cards in Linux using agpgart.

[Pathik]

Yea. That AGI part really sucks.
@Mehul, And I have a Asrock i845GV mobo. Really b0rked in case of most linux distros.
I get some or the other error with every Distro.
@Gary, Yea i know.
@praka, Thanks man. I ll try that out.

[mehulved]

So, there goes your problem. You'll have to do eith this ugly hack. It's always been a PITA for linux users.
