Refresh Rate!
 

this is so annoying. my monitor keeps blinking in ubuntu because the refresh rate is too high (75hz) and i dont know how to change it to where it should be (60) i tried to add a modelin and all this other stuff but nothing worked

I don't know of the specific graphical tool that ubuntu would use to change this but if your up for it crack open a terminal and locate xorg.conf (should be in /etc/X11/ or there abouts). Modify the monitor section of the file with your favourite text editor so the refresh rate is correct. That should fix ubuntu's wagon.

the problem is that there is nothing in there specifying a refresh rate

Oh, strange. I didn't realize Ubuntu shipped with an incomplete xorg.conf. Try adding the following to the monitor section:
Then restart X. Hopefully this will fix you up.

thanx for the info unfortunately it still doesnt work the only option remains 75. however, when i lower the resolution i can choose 60 but it looks hoooorible!!!!!! this is so aggravating i have struggled to get this thing up and running. i cant even enjoy it right now. maybe windows is the way

what's the make an model of your monitor? Refresh rates are directly related to resolution. If you can find the exact specs for your monitor someplace then you can put them into xorg.conf and it should chose the correct refresh rates/resolutions on its own.

Hyundai Imagequest N19S with max resolution at 1280x1024 the recommended resolution is the 1280x1024 at 60hz (which it operates in when using windows) the horizsynch is 30-80 and vertrefresh is 60~75. i entered this info and even a modeline and NOTHING worked. ive tried everything

Try running xorgconfig at the command line and entering your specs that way. Since it seems that manually editing xorg.conf isn't working I doubt you'll have a lot of luck, but it may be worth a shot. Back up your old xorg.conf first and be sure to know the driver settings for your mouse first, it will write a completely new file.

nothing doing. but as a side note, do you think the refresh rate is causng the problem because im starting to believe its something else
