I have find very odd and crude solution to this entire episode. It is as follows
- Start installing ubuntu as usual.
- Switch off the monitor
- Wait for some time (1-2 minutes) till the HDD access stops .
- At this point ubuntu needs some input from the user
- Now Switch on the monitor and high chances are that you will see ubuntu normally no out of frequency issues.
Now onwards there will not be any 'out of frequency' issue.
I have successfully installed ubuntu with this workaround.
It is quite useful for newbies in ubuntu. As all other ways are somewhat complex to do especially for a newbie.
Thank you all especially bain who guide me thru the maze.
===================================================================================================The issue i was facing few months ago=======================
I was trying to install Ubuntu 14.04 on p4 . but it was not getting installed due to some issues which i do not understand. it used to give ' Frequency out of range ' message and the monitor used to go into 'stand by mode' . I could never install ubuntu with the old CRT monitor. So i borrowed a latest LCD monitor and was able to install ubuntu successfully. Now i want to use my old monitor so i changed the monitor back to CRT but it again start giving the same error. Experts are requested to guide me about how to change the monitor of the successfully installed Ubuntu. The details are as follows.
My hardware :=
P4 3.06 MHz / 2 GB ram / 10 Gb hdd totally dedicated to Ubuntu / 2gb swap space.
MoBo Mercury P4 266aNDMx 865 Equivalent.
Monitor LG CRT Studioworks 500G (8 Years old ) with max resolution of 1024 X 768.
The entire hardware works perfectly under XP.
Error Message :-
Out of frequency
HF 68.7 KHz
HF 30 - 54 kHz VF 50 - 120 Hz
The monitor starts a 15 sec countdown with 'Frequency out or range box'
before entering power saving mode.
On the LCD monitor I have changed following settings within Ubuntu before switching over to CRT monitor.
grub GRUB_GRXMODE changed twice once for 800X600 as well as for 1024X768 followed by sudo ubdate-grub each time.
monitor resolution correspondingly was adjusted in ubuntu for 800X600 as well as 1024X768.
The ' Out of frequency ' may be happening due to some different reason. Experts comment.
XRandr output for LCD is
1360x768 60.0* 1024x768 75.0 60.0 70.0 800x600 75.0 60.0 72.0 56.0 640x480 75.0 60.0 73.0 512x384 75.0 70.0 60.0 400x300 75.0 72.0 60.0 56.0 320x240 75.0 73.0 60.0
Decoded EDID from Xorg log:
Checksum Correct Section "Monitor" Identifier "505E" ModelName "505E" VendorName "GSM" # Monitor Manufactured week 3 of 2005 # EDID version 1.3 # Analog Display DisplaySize 280 210 Gamma 2.76 Option "DPMS" "true" Horizsync 30-54 VertRefresh 50-120 # Maximum pixel clock is 70MHz #Not giving standard mode: 640x480, 85Hz #Not giving standard mode: 800x600, 85Hz Modeline "Mode 0" -hsync -vsync Modeline "Mode 1" +hsync +vsync EndSection
According to this page the monitor specs are:
Max Resolution : Manual : 1024 x 768 / 65 Hz Recommended Resolution : 800 x 600 / 85 Hz H-Scanning Frequency : 30 ~ 54 kHz V-Scanning Frequency : 50 ~ 120 Hz Pixel Frequency : 65 MHz
Xorg detects pixel clock as 75 Mhz. I think this monitor is capable of displaying an interlaced signal upto 120 Mhz which is why the frequency calculation is wrong.
I did not tell you earlier that the installation procedure had worked perfectly with same CRT monitor for buntu 7.04 but ironically the issue has started for newer versions!
I have tried totally 4 versions of Ubuntu 7.04, 11.10, 12.10, 14.04LTA.
Any way keep reading
I tried to generate Xorg.conf file on CRT on a terminal tty1, and the server has crashed here is the url of the log file http://paste.ubuntu.com/7521633/ it may be of some help.
Xorg has stopped unexpectedly
Also read this lengthy message may be of any use.
