Monitor Refresh Rate


Hi team

I am running Ubuntu 5.04 (and loving it!) and I would like to have my monitor at a resolution of 1152x864 and a refresh rate of 70Hz.

When i set it to a resolution of 1152x864 i can only select 75 Hz. My monitor is capable of 75 Hz, but when I set it to that refresh rate it will run fine for a while and then later there will be a high pitched sound from the monitor (did this with XP too)

How can I achieve a resolution of 1152x864 with a refresh of 70? I am a linux newb and would really appreciate some clear and careful instructions

My monitor is a viewsonic e70 CRT.

Thanks.

edit: Actually, please wait for confirmation that this will actually work before you do this. This might be different than the previous distro I was using.

Hi Redmoon -

I'm also relatively new to ubuntu, and I'm pretty happy with it.

I believe the best way to force your monitor to use a non-default resolution is by editing your xorg.conf file, which is located under /etc/X11. You need to be logged in as root/superuser to do this. So start off by logging in using the "su" command. Then cd over to /etc/X11.

First I'd back up the xorg.conf file by using the command "cp xorg.conf xorg.conf.backup". (In case a problem occurs and you can only access the console, simply remove xorg.conf and rename xorg.conf.backup to xorg.conf).

Open up xorg.conf with a text editor and go down to the "monitor" section. Within this section, there should also be a setting for resolution (look for yours, 1152 x 864). I think you can simply add "@ 70 hz" to the end of the resolution and it will now set 70 hz as the default refresh rate.

If you need more detailed instuctions than that, let me know.
