Hi, i'm a newbie
i hav just moved from fedora 3 to slack 10.2 how do i set the screen refresh rate? there isn't seem to be an option in the control center?

app_menu > system > krandrtray

is how I do it from within the KDE desktop.

(I'm sure there's other ways to do it too)

I forget the specifics (may need to click advanced and set it to "always start with this setting", etc. etc. etc.

In the control centre (kde) Peripherals > display
is another way

I believe available refresh rates in the KDE tool will be determined by having the correct parameters entered in xorg.conf for your monitor.

Having the correct driver for your video card is also helpful. In the case of nvidia or ati, the "nv" or "ati" driver should be enough to give you good refresh rates - though not enough for 3D acceleration.

Once these are entered, you will have a range of refresh rates available to you (or at least one acceptable one) that match your system in the KDE configuration tool.

As an FYI, the out-of the-box X configuration in Slackware will give you a headache inducing 60 Hz refresh using the vesa driver.

My experience has been that entering the correct frequency data for your monitor into xorg.conf is the simplest way to get what you are looking for. I don't use the krandtray tool.

For example, the default frequencies in xorg.conf are:

HorizSync 31.5 - 50.0
VertRefresh 40-90

Changing them to the following for my monitor:

HorizSync 31 - 86
VertRefresh 50-180

And replacing "vesa" with "nv" as the video driver for my nvidia card was all I needed to do. An acceptable refresh rate was established by X automagically after that. Of course, I did edit the file to change the default screen resolution and eventually compiled the driver from nvidia, but this is not needed to get a decent refresh rate.

Hi Franklin,

I'm glad you mentioned everything.

Actually, I use the krandrtray tool to *lower* my refresh rate.

(when I first set up Slackware) I run what is it, xorgconfig which in turn runs me through to enter all of those values you mentioned (very important). (to newbie, this is very important because otherwise, as already reported in this thread, the default out of the box Slack uses a rather generic) which most often does works but it is not meant to leave it that way nor to try to *just tweak up the refresh rate* either.

It is very important to get the correct values and driver into xorg.conf file *and then and only if needed* it's ok to become concerned with the refresh rate.

My crt monitor can do 1280x1024 at 75hz refresh rate

I use screen res. of 1024x768 in which Xorg automagically uses about 85hz refresh rate (which should be fine, my monitor can handle)

But I'm quirky and just because I think my monitor might last 25+ years instead of 5 years if I set the refresh from 85 down to 72

which is what I do as a one time only thing using krandrtray to do it.

Other than that, I don't use the krandrtray tool.

Your eyes are far more valuable than your monitor. If your monitor can do 85, do 85. I sit in front of a computer 10-12 hours a day - and that's just work. The difference between 75 and 85 is significant over long periods.

Totally agreed, besides, if you happen to like fps video games, specially qw, it means a huge difference. The higher you can go, the better
