Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

hello. I am running Slackware Linux 10.2 and kernel 2.4.31
I have Dell Trinitron UltraScan P991 monitor. Its specifications say its horizontal refresh rate is 30-107 kHz and its vertical refresh rate is 48-120 Hz. I have entered these values in xorg.conf and I have set the default resolution to 1024x768. Now my monitor s working at vertical refresh rate of 85 Hz. Is there some way to set the vertical refresh rate at some higher value? Under Windows I set it at 120 Hz and a similar resilution. I would be glad if I set the vertical refresh rate at 100 Hz and resolution of 1024x768.
You could try your own modeline.
Enter the command "gtf 1024 786 100 -x5
Remove the trailing ".00" from the name "1024x786_100.00" -> "1024x786_100".
If your xorg.conf file is the type with a modeline section, then place the modeline there, and add "1024x786_100" to the Screen section's modes. For example, emphasized the lines that I used to get 1280x800 resolution on my laptop.
I did what you told me. I ran "gtf 1024 768 100 -x". The output was:
# 1024x768 @ 100.00 Hz (GTF) hsync: 81.40 kHz; pclk: 113.31 MHz
Modeline "1024x768_100.00" 113.31 1024 1096 1208 1392 768 769 772 814 -HSync +Vsync
I added this to the end of my "Monitor" section in xorg.conf. When I restarted X11 the vertical refresh rate was as I wished-101Hz. But What I found out is that when I open an application, for example a web browser of Kate or whatever, the right edge of the application's window is somewhat "clipped" - I do not see the scrollbar, the "x" button at the upper-right end. I do not see the rigt panel-hiding button. It looks like the desktop has "expanded" but I do not see all of it on the screen. Do you have any idea what it is, any remedy?
Oh, I solved that problem myself I just had to tune the monitor itself with its buttons. Thank you very much indeed . Now everything seems to be all right. The only thing that puzzles me is that when I go to the "Configure Desktop"->"Display" menu, it says that the refresh rate is 101 hz, and when I press the button on my monitor it says that it is working at 104 Hz. What is that discrepancy due to?
I see. There is no trouble I thing in leaving things as they are now? The monitor really works at a refresh rate of about 100Hz and everything is pretty good. Is there any potential problem arising out of that?
My videocard is Intel(R) 82845G Graphics Controller. I couldn't find any relevant info in the internet abot whether it supports 1024x768 at 100Hz. Concerning the monitor, its documentation says teh following:
Horizontal scan range: 30 kHz to 107 kHz (automatic)
Vertical scan range: 48 Hz to 120 Hz (automatic)
Optimal preset resolution: 1024 x 768 or 1280 x 1024 at 85 Hz
Highest preset resolution: 1600 x 1200 at 85 Hz
I am currently using it at 1024x768 at about 100Hz. In windows I have set it to work at 120 Hz. However, it seems to me that it is not too healthy for it to work at such high frequencies. I hope that the current configuration is as well ok. What do you think?
ok,thank you very much indeed it was quite a helpful discussion
My next problem is installing the webcam and the UPS software, but I do not have any idea in which forum to post. My webcam install thread has sat in this forum for several days now with no answer. Would you suggest me in which forum to post it
