Hi everyone,
I'm not positive how to explain the problem, will do my best.
I have a KISS technologies coolview3 monitor, tft widescreen 17".
Graphics card is a Creative GeForce2 GTS
Under mandrake 10.1 I got a decent picture, under 2005 LE I have
problems. I think xorg is the significant change - so could be
related
to that.
The colour of the display is darker, and there are stripes across the
screen horizontally that match darker parts of windows.
eg the title bar of a window in middle of the screen 'bleeds' left
and
right as does any instance of a darker colour on my screen.
Is this some issue with my graphics card, or my monitor, and suport
for them in xorg?
Do the symptoms sound familiar to anyone?
many thanks for any help offered
Well, I don't have any direct experence, but you may want to double
check the monitor settings in your config. You may be using ether too
high a frequency, or just one the monitor doesn't like. I am more used
to monitors going blank (newer monitors) or letting out the "magic
smoke" (older monitors) when driven at too high a frequency, but it is
worth looking into.

The monitor settings are those that I used in 10.1 - and that I use
in windowsXP. SO I don't think it's that.
I don't suppose the nv driver in xorg is 'known' to be problematic?
As root,
'urpmi monitor-edid' if it isn't already installed, and then...
'monitor-edid'
The output will end in the preferred resolution and modeline for
your particular monitor, read directly from the monitor's firmware.
The is the one you should have in xorg.conf and the one you should
choose when running 'XFdrake' (or from mcc).
I use the nv driver on 2006.0, and have for several MDV versions
for years with a GeF4. It is not the problem.
Thanks Tom - useful info..
monitor-edid gave me a suggested modeline of:
ModeLine "1280x1024" 135 1280 1296 1440 1688 1024 1025 1028 1066 -hsync
-vsync
However.. I'm not sure about that... my monitor is widescreen - so
surely I want something mor eline 1280x768 ?
For comparison my xorg.conf has:
# modeline generated by gtf(1) [handled by XFdrake]
ModeLine "1280x768_120" 173.82 1280 1376 1520 1760 768 769 772
823 -HSync +Vsync
# modeline generated by gtf(1) [handled by XFdrake]
ModeLine "1280x768_100" 141.96 1280 1376 1512 1744 768 769 772
814 -HSync +Vsync

# modeline generated by gtf(1) [handled by XFdrake]
ModeLine "1280x768_60" 80.14 1280 1344 1480 1680 768 769 772 795

-HSync +Vsync
I note that my conf file has +Vsync and the monitor-edid gave back a
-Vsync should I guess that would make a big difference?
I dunno, my 19" LCD returns '+' for both. I vaguely remember
that has to do with interlacing. I'm not sure what you mean by
'widescreen' either. Mine is termed as such, but the screen is just
1.25:1 compared to a crt's 1.33:1. FWIW, here's my monitor-edid.
Note screen size an aspect ratio
tom # monitor-edid
Name: SyncMaster
EISA ID: SAM0080
Screen size: 38.0 cm x 31.0 cm (19.31 inches, aspect ratio 5/4 = 1.25)

ModeLine "1280x1024" 108 1280 1328 1440 1688 1024 1025 1028
1066 +hsync +vsync
The 2005LE fresh install should'a tried to use
'monitor-get-edid' (which produces binary output) to config xorg
when a flat screen monitor is detected. You might try
'monitor-probe-using-X nv' and the results of 'monitor-get-edid'
piped to a file, and send those to Pixel as instructed in the
results of the probe command (which includes his email address).
I believe I'd try running XFdrak an selecting 1024x768 first
tho. While your montior might report it's capable at 1280x1024,
1024x768 is more normal for a 17". Monitors might be able to be
'overdriven' with Windoze, but it's not a good idea with Linux. Much
as I believe that's what Mikkel was also advising.
My Samsung will run fine at 1600x1200, but that's just too
much for a 19". Monitor vendors have long overstated their specs,
on the assumption the hardware will be used with Win$ux, rather than
a real OS. ( Sorry, ya probly didn't wanna hear that ;)
