Hello Jonathan, Looks like you have picked a tough one here :-) On Feb 6, 12:50am, Jonathan Markevich wrote:

I know you're just so anxious to hear more from me! No problem
Sorry for the tardy response, I have fallen behind on my e-mail and several other things -- the day job is interfering.
This is very strange, I read the video mode timings HOWTO and it seems out to lunch. Even the math of his own example doesn't fit his explanations.
That is a tough go, am not sure of the calculations either.
This is in my XF86Config:
# 1024x768 @ 76 Hz, 62.5 kHz hsync Modeline "1024x768" 85 1024 1032 1152 1360 768 784 787 823
My monitor CAN handle 1024x768 @ 76Hz (it can apparenly go up to 80Hz)
So where am I overdriving it? What should I change? Is there a better place to find this info?
This all looks fine except that you are still having the problem. I had a look at the XFree86 site for information, and there are some issues with that card and it's setup. Doesn't look like anything major though. Have a look at any rate. So what to do now? What I would try first is to make certain that I had the latest server version from XFree. I know you'd like to use the SuSE server but we can do that later once we get something stable running. What I am getting at is to use XF86Setup to do a basic server setup. If the following appears to be simplistic please note that no insults to your intelligence are intended, just trying to get a basic known setup that works. This is offered on a take or leave basis and your millage may vary. Setup the mouse -- if memory serves that is the first step. Setup the keyboard -- using the apply button on this and above. Can't remember for sure what come next the monitor or the card, but I think it's the card -- anyway when you get to these this is where the basic stuff comes in. Setting up the card -- just select the card you have from the list, don't do any detailed setup, let XFree do that. Setting up the monitor -- when you get that screen -- don't select a resolution, enter the correct vertical and horizontal frequency rates for your monitor on the respective lines. They are right above the big section listing various resolutions etc. Then just complete the last screen -- don't need any changes there. From there follow the instructions for setting links or what ever it want's to do. It will attempt to start the server, and if sucessfull will put you into xvidtune. Look at the raster for any weird stuff happening. If there is then we already have a problem with the setup. If it looks OK, I wouldn't make any changes with xvidtune just yet, let the cards fall where they may for know. After xvidtune lites up click on apply and save the config. This should give a whole array of video modes supported by your monitor and card to select from. Let it make the links and shutdown the server. Restart the server using just startx. You can select different video modes using the Ctrl+Alt and the + & - keys on the number keypad. This will allow inspection of various resolutions at the 8bit color depth. Hopefully all is well. Shut down the server and restart it like so: startx -- -bpp 16, and repeat the above checking that the image is stable at each resolution. Shutdown and restart the server using the above command but substitute 24 & 32 for 16 and recheck all resolutions for stability. I use the Matrox Millennium and 24 bit color depth is flakey but 32 bit works fine -- go figure hey. If everything goes well and is stable. then when you have a server running in 32 bit color mode at highest resolution, grab an xterm and fire up xvidtune and adjust the image to your liking, while paying attention to stability. When I use xvidtune after acknowledging it starting, I click on apply before making any changes. I have found that if any adjustments to the image are done that lie outside the frequency specification of your monitor, xvidtune will complain and you'll have to backout the last attempted change before going on. If all is well click on apply and save and let it make the links or what ever it wants to do. Restart the xserver and make sure all is well. If it is, then /etc/XFConfig should have an array of known working modes that can be used to fine tune or re-setup X using a differnet server <real big grin>... Good luck and best regards. Let me know how it works out. Frank -- To get out of this list, please send email to majordomo@suse.com with this text in its body: unsubscribe suse-linux-e
