- actually, I have found that clocks.exe lies about the clocks.
- (or more accurately, it doesn't find them all).

- Oren wrote a guide to setting up X11 for me and has granted permission

- Howdy,

- Well, here's a hopefully descriptive enuf way for you to get X11 up
- and running on your machine. The most important file in this case is the
- file /usr/lib/X11/Xconfig. This file has fields in it that tell X11 where
- to find some of the hardware and screen measurements. I'll go thru those
- that you might need to change from the default Xconfig to get X11 configured
- properly.
-
- First variable in Xconfig you should check is the FontPath variable. This
- variable tells X11 where to find the fonts information it needs to be able
- to display things. Since I have the 75dpi font package installed, I use:
-
- FontPath "/usr/lib/X11/fonts/misc/,/usr/lib/X11/fonts/75dpi/"
-
- if you don't have the 75dpi font package installed, make sure to use:
-
- FontPath "/usr/lib/X11/fonts/misc/"
-
- [Note: you need the 75dpi fonts to use olvwm -- Open Look Virtual Window
- Manager -- but I installed it so I can have a more ``complete'' X11 system].
-
- You shouldn't have to touch anything relating to the Keyboard section of the
- Xconfig. I didn't and so I don't know much about it.
-
- Next comes the mouse configuration. In this section, the most important thing
- to do is get the right type of mouse and the device its installed on! If you
- look at the default stuff it should look something like this:
-
- Microsoft "/dev/ttys0"
- #MouseSystems "/dev/ttys2"
- #MMSeries "/dev/ttys2"
- #Logitech "/dev/ttys2"
- #MouseMan "/dev/ttys2"
- #Busmouse "/dev/ttys2"
- BaudRate 1200
- # SampleRate 150
- Emulate3Buttons
-
- Since I have a serial, 2 button Microsoft mouse I use the Microsoft entry. I
- also used the MCC-interim 96c release and my mouse is on COM1 == device with
- major 4, minor 64. On the MCC installation, this translates to /dev/ttys0:
-
- crw-rw-rw- 1 root root 4, 64 Aug 5 01:10 /dev/ttys0
-
- The Emulate3Buttons came with the default Xconfig and should probably be left
- alone (same goes for the BaudRate). The Emulate3Buttons variable tells X11
- that the mouse is a 2 button mouse and when both buttons are pressed, it should
- emulate the third button (as normally X11 uses 3 button mice :).
-
- Finally we come to the most important section -- the one that most people have
- trouble with -- the screen stuff. [this is the vga256 section]
-
- Ok... as you said, you have the clock.exe program that you used to get your
- clock values from. I didn't particularly find it that useful... especially
- with X11 v1.1. See, at the time, I had to use the HiColor (hiclock?) hack
- to get things to work properly. Anyway, v1.1 seems to figure out the clock
- values correctly and sends the info out to stderr (I think :). So, what you
- should do is:
-
- startx 2> startx.clks
-
- I don't know what yer current situ is with X -- how far you have it working or
- non-working... but as soon as you exit it, take a look at startx.clks. In my
- case it looks like:
-
- waiting for X server to shut down X386 Version 1.2 / X Windows System
- [linux v1.1] (protocol Version 11, revision 0, vendor release 5000)
-
- VGA256: et4000 (mem: 1024k clocks: 25 28 56 70 78 71 57 62 14 0 33 36 40 30
- 0 32)
-
- Notice obviously how the chipset is an et4000 with 1 meg on the card and then
- the clock values X11 was able to find. These are the clock values I use on
- the "Clocks" line. So, the beginning of my vga256 section looks like:
-
- vga256
- Virtual 1024 768
- ViewPort 0 0
- Modes "640x480" "800x600" "920x690" "1024x768i"
- #Modes "1024x768"
- #Clocks 25 28 57 72 78 68 50 62
- Clocks 25 28 56 70 78 71 57 62 14 0 33 36 40 30 0 32
- #Staticgray
- #Grayscale
- #Staticcolor
- #Pseudocolor
- #Truecolor
- #Directcolor
- Chipset "et4000"
- #Chipset "et3000"
- #Chipset "gvga"
- #Chipset "pvga1"
- #Displaysize 1024 768
- #Screenno 0
- #Vendor "legend"
- Videoram 1024
-
- The "Virtual" section translate to how big you want your desktop to be. For
- example, when I use a 640x480 screen, when I reach the borders, since the
- desktop of 1024x768 can't be seen on a screen of only 640x480, the window
- slides downward and sideways. So you can only see a 640x480 into the desktop
- at any time. ViewPort should probably be left alone (from the default). Modes
- tells X11 which display modes you have available. The above 4 all work for me,
- so once I'm in X I can use the CTRL+ALT+<NumericPad +> and <NumericPad -> to
- go to the next and previous modes, respectively. As you can see, the next few
- variables I left as they came in the default Xconfig, and uncommented the
- Chipset variable to tell X11 I'm using an et4000 chipset. After a few more
- variables that I left commented out, Videoram is set to 1024 == 1024K == 1meg
- (which is how much memory I have on the card). That's it for that. Next comes
- the ModeDB (Mode DataBase) section. In my case I have:
-
- ModeDB
- # clock horzontal timing vertical timing
- "640x480" 0 640 672 768 800 480 490 492 525
- "640x480" 25 640 672 768 800 480 490 492 525
-
- "800x600" 71 800 832 1096 1128 600 600 613 630
-
- # "800x600" 40 800 816 952 1056 600 608 610 633
- # 36 800 832 966 966 600 600 609 631
- # 39 800 872 968 1104 600 600 606 624
- # 36 800 864 896 1008 600 600 606 624
-
- "920x690" 71 920 952 1088 1168 690 688 718 724
-
- "1024x768i" 40 1024 1064 1224 1264 768 777 785 817 Interlace
-
- # "1024x768" 28 1024 1092 1220 1344 768 786 791 810
- # 62 1024 1096 1272 1328 768 776 778 808
- # 62 1024 1072 1176 1272 768 778 779 804
- # 62 1024 1072 1200 1240 768 766 782 786
-
- "1152x900" 57 1152 1184 1288 1360 900 898 929 939 Interlace
-
- What these translate to is which clock belongs to which type of screen. As
- you can see, both the 0 and 25 clocks will let me view a 640x480 screen
- well. Also, while both the 71 and 40 clocks let me view 800x600 well, I
- decided that the 71 clock showed had a sharper image. I clock field is
- really the one you should play with to get the right nicest looking screen.
- I admit I did this with trial and error, but there is a better way to do this.
- Remember that the Mode and Clocks lines looks like:
-
- Modes "640x480" "800x600" "920x690" "1024x768i"
- Clocks 25 28 56 70 78 71 57 62 14 0 33 36 40 30 0 32
-
- and lets say the 800x600 stuff looks likes:
-
- "800x600" 71 800 832 1096 1128 600 600 613 630
-
- so what you can do is use:
- Modes "800x600x1" "800x600x2" "800x600x3" "800x600x4"..."800x600x16"
-
- [note that I use the elipse cause I'm lazy... cause it won't work in the
- modes line, as far as I know, and you need to enter all of them :-]
-
- Next you enter in the ModeDB part:
-
- "800x600x1" 25 800 832 1096 1128 600 600 613 630
- "800x600x2" 28 800 832 1096 1128 600 600 613 630
- "800x600x3" 56 800 832 1096 1128 600 600 613 630
- "800x600x4" 70 800 832 1096 1128 600 600 613 630
- [...]
- "800x600x16" 32 800 832 1096 1128 600 600 613 630
-
- I think you get the picture :-) What this lets you do is go into 800x600 mode
- with every clock you have and use CTRL+ALT+<NumericPad +> (and -) to switch
- back and forth between clocks to see which one lets you view 800x600 clearly.
- Make yourself a little chart so that you know which clock value you are at
- at any time. With the above, I'd enter X11 with a clock of 25 then after the
- first CTRL+ALT+<NumericPad +> I'd be put in clock 28, then 56, and so forth.
- After you decide which one is the best for you can exit X and delete the others
- and do the same for "1024x768", etc. Also, BEFORE you move on to the next
- screen (from 800x600 -> 1024x768) you might wanna try to put the Interlace
- keyword with all the entries and try it, like:
-
- "800x600x1" 25 800 832 1096 1128 600 600 613 630 Interlace
- "800x600x2" 28 800 832 1096 1128 600 600 613 630 Interlace
- "800x600x3" 56 800 832 1096 1128 600 600 613 630 Interlace
- "800x600x4" 70 800 832 1096 1128 600 600 613 630 Interlace
- [...]
- "800x600x16" 32 800 832 1096 1128 600 600 613 630 Interlace
-
- And try to see if you get a better interlaced picture than you do
- non-interlaced. I, for example, can't seem to have non-interlaced 1024x768
- mode. Hence I use interlaced (my "1024x768i" -- the i is only there to tell me
- that its interlaced not X11, for X11 to know that the Interlaced keyword is
- placed at the end of the line as above). After you are done playing around
- with all this you can delete any extra stuff (or comment it out) and put the
- ones you like in the Mode line so you can switch back and forth between them
- while you are in X. I find it useful, for example, to usually work with only
- 640x480 screen [especially since I use olvwm and have a virtual desktop] or
- 800x600 screen and only flip to a higher resolution when I need it -- like when
- trying to view a DVI with xdvi. But, I guess you'll make up your mind after
- you play around with things a bit :-)
-
- Well, hope this clears up some questions you might have/had... Hope you get
- things to work properly so you can X to your heart's content :-) [I'm a non
- graphics/ascii guy, m'self :-]. And if you have any questions, you know
- where to reach me!
-
- G'luck and have a good one,
- Oren.
