View Full Version : [ubuntu] Current Input Timing not supported by Monitor Display

May 12th, 2011, 09:31 AM

I recently upgraded to Ubuntu 11.04 , and on reboot the following message was displayed on my monitor

The current input timing is not supported by the monitor display.
Please change your input timing to 1366*768@60Hz or any other monitor listed timing as per the monitor specificationsMy monitor specifications are Dell IN1920 LCD.

I searched a lot for the solution on this issue but none of them seem to work. I am unable to proceed as the GRUB is also not visible.

Any help in solving this problem would be greatly appreciated.

Thanks in advance

Try connecting it to another display.If it works then change the resolution to the required amount

Hi Najubhai,

I do not have access to another monitor as this is my Home PC.

Therefore would like to know if there are any other solutions to this problem.

When your PC starts and you choose to load Ubuntu (from BIOS not Grub2)
there will be a purple screen,press left shift or esc then you'll get access to grub menu on first line there will be "Ubuntu 11.04 with Linux 2.xx (generic)"
Hover your selection over it and press e
some 5 or 6 lines will show up

On the line which starts with linux \boot go to the end of that sentence and then type:
If you have ATi GPU : radeon.modeset=0
If you have NVidia : nomodeset
For Generic : xforcevesa

after that press ctrl+x

Hopefully it will boot to the GUI and there you can change the resolution.

Hope that helps :)

I would like to know your results. My system went into kernel panic while updating and now the same statement is made. I can't get past post.
