ubuntu 10.04 in old monitor

[kishordgupta]

i have very old monitor which could not support more than 800*600*16.
so when i use winxp or win 7 i have to set enable vga mode. but ubuntu 10,04 it was not possible.

after install ubuntu 10.04 , when gui cames monitor screen became distorted.
so i go grub menu press e and add vga=0314 beside "quite splash" but i got "VGA=0314 is deprecated. Use set GFX payload=[h][w][] using the linux command instead." error and nothing happened.

then i go grub menu bu pressing crtl+c from boot option and then write command
set gfxmode=800*600*16 but no error shown but nothing worked. also i write several command like set gfxplaymode=... etc. but nothing work.

i use ubuntu 9.04 without any troubles in this machine. so i need help.

also i can go terminal by shellmenu but its also distorted, so i cant edit grub file. i can only write in grub menu.

thanks

Hi and Welcome !

i got "VGA=0314 is deprecated

Deprecated doesn't mean that it's not supported. It means there is a new method available and you should use that only.
Have you tried vga=258 and 276? Check here.

Boot up from LiveCD of any Linux distro and mount / partition of Ubuntu. Edit existing ( or create new ) /etc/X11/xorg.conf file and set Refresh Rates supported by your Monitor.

These contents should work fine :

Section "Device"
       Identifier "Configured Video Device"
       Driver    "vesa"  
EndSection

Section "Monitor"
         Identifier "Configured Monitor"
         HorizSync 31.5 - 70.0
         VertRefresh 50 - 160
 EndSection

Section "Screen"
        Identifier "Default Screen"
        Monitor "Configured Monitor"
        Device "Configured Video Device"
        DefaultDepth 24
        Subsection "Display"
             Depth 24
             Modes "1024x768" "800x600"
        EndSubsection
EndSection
