Resolution Problem Question
This may be an OS or hardware problem:
Sometimes on my SuSe 9.1 machine the konqueror, kmail, firefox and thunderbird
windows garble the text and/or graphics in horizantal strips across the window contents. Sometimes it does it in the address area of the mail windows. Scrolling up and down in the given window usually fixes the moshed text, sometimes it takes multiple scrolls and it may fix the bad area but create a different bad area. I also see the garbling of the slider bar in the console windows.
I use this same monitor on a switch to other machines. The garbling never happens when switched to windows 98 or windows 2000.
I think the problem is in the XF86Config file. The monitor is a Slyvania F74 17". I have the original driver CD and manual that lists the horizontal and vertical ranges. I have set it with Sax2 and have verified that the ranges and names are in the file. The file says generated by SaX and not to modify. I had to make the only manual change I have done to the file is to lower the high ranges in both the vertical and horizontal fields. I did this to prevent all of the text in the graphic frames and other body text from being in a font size less than bible print.
I made these changes gradually stopping the X processes via a reboot until I came up with a frame font size I could see. I made backups along the way. Of course I could change font sizes in the body of documents, but the frame fonts was the issue. The manual says the ranges are Horiz 30-70 and Vert 55-120. I have pasted the pertinant file section below.
I have the SuSe 9.1 bible that came with the OS DVD, and it does not give an example of the file although it discusses it and talks about these frequency ranges. The word resolution is not in it's index.
The other question is about the modeline that I pasted in below. My manual says the max resolution is 1280x1024. I could change the 640x480 but I don't know what that string of numbers following it means. I could keep experimenting or upgrade but I thought I would ask. Experimenting takes lots of time and may still be fruitless, upgrading may fix or open a new can of worms.
My /var/log/XFree86.0.log states that it is not using the default of 640x480
but it also says it is not using the default of 1280x1024 and all other ranges
as well. The log does tell me that it knows the H and Vsync ranges and that
it is using the ones I have lowered in the sample below. The log statement
from the XFree86 community states not to ask them any questions until you
have the latest version.
For the record I have XFree86 Version 4.3.99.902 (4.4.0 RC 2)
Section "Monitor"
Option "CalcAlgorithm" "CheckDesktopGeometry"
HorizSync 30-50
Identifier "Monitor[0]"
ModelName "SYLVANIA F74"
VendorName "SYLVANIA"
VertRefresh 55-90
UseModes "Modes[0]"
EndSection
Section "Modes"
Identifier "Modes[0]"
Modeline "640x480" 51.43 640 680 744 832 480 481 484 482
EndSection
Thanks in advance,

My impression is that this relates to the video driver (graphics card) more than the display settings (monitor model). Could you provide that info as well?
Since 9.1 is 4 years out-of-date, I'd recommend upgrading. Many improvements have been made since 2004.

Bob,
I was thinking if it wasn't the config, it may be a RAM issue. The card does have 8 mb RAM on board
and the system itself has 256 mb RAM and the CPU is 650mhz, on a 686. I also have a jpg snapshot of yast desktop display and yast control center but don't know where to attach it. In that snapshot, I can see a disagreement in what yast reports in both screens and they both disagree with whats in the XF86Config log.
Upgrading is an option from the net and I may do it if this problem persists or gets worse. As for now I am trying to get a handle on what boot apps. By that I mean the correct run order of X and how it flows, not the rc run order of all boot start apps.
here is the hardware info I could get:
lspci = Display controller: Texas Instruments TVP4020 [Permedia 2] (rev 01)
I did a Yast hardware scan for more info and it may be too much.

This definitely sounds like a video card driver issue. I agree; I would upgrade to a newer version and driver.
