Unique LCD problem.
 
I am running Red Hat 7.1 on a Micron Trek 2. Its a 266mhz system with 192mb ram. The LCD is a 1024x780(I think)close to it anyways. The problem occures when trying to setup the screen size. When I do a xconfig the first question it ask is what size monitor so I put the 1024x780. Then it asks me what kind of moniter. Since its not listed I use a generic 1024x780. Then it ask me the color depth and screen size. The highest one I can use is 800x600 24bit. Thats fine,but it uses a much smaller screen size. Now I have this anoying black border around the work space. How do I strech this screen to fit that of my LCD on my laptop?

you must first make sure that you entered the proper values in x's configuration. you can find these values in your monitor's manual. if you don't have the manual, you can perhaps download it in the company's website. use google. you can also find some site vendors that show some specs about the monitor.

also don't forget your video card's specs btw.

Is your video card capable of 1028x768 at 24bit depth?

weird LCD problem
 
yes. Its supposed to display 1024x780x64 but when I use those setting(and I tried every custom variation and the generic selections)the thing threw at me. All I get is a black screen and the most extrem right hand side is a strip of the xwindow from the very top of the screen to the very buttom

Oh, and the only resolution that works is 800x600 in 8,16,and 24 bit. I would use just that setting,but theres this really anoying black border. I would love to have 800x600 as a full screen. Is that possible?

Look for some specs on the web, because your vertical pixel count looks off. Normally it will be devisable by 8.

meltdown_override 08-04-2006 08:29 AM

Im feeling like a real dumba**,but how do I set up the verticcal pixel count? is that the resolkution like 1024x780? The specs I can find seems to to point to that particular resolution. I've read elsewhere that messing around with custom settings and using the wrong setting could damage the vid card and lcd is that true?

it's like
Code:

        HorizSync 30 - 70 # DDC-probed by ddcxinfo
        VertRefresh 50 - 160 # DDC-probed by ddcxinfo

The resolution is 1024x768.

It can display 64K colors.

Thank you for the help :)

meltdown_override 08-04-2006 09:28 AM

no those refresh rates did not work. I still get KDE as a thin strip down the right hand side. Do yall think something could be messed up on the actual video card? I know its not the LCD because during POST I get the full screen

jschiwal 08-04-2006 09:29 AM

You are welcome. To answer your earlier question about setting a non-available resolutions, let's suppose that your laptop had a 1280x800 screen, but that resolution wasn't available in the setup. You could run the "gtf" program (a part of xorg install):
gtf 1280 1024 56 -x

This would generate a custom modeline that you could add to the "Monitor" section.

Ok I've been fiddling with this and found out that 1024x768 works if I switch to tv mode and then switch back. When I do this I get a full screen,yet there is a horizontal black strip thats spans the entire screen. My pointer seems to go behind this strip as if there is no screen there. I have never seen this before on any mach

meltdown_override 08-04-2006 02:40 PM

this black strip seems to be blacker than the blackest black on my screen.

jschiwal 08-05-2006 09:47 PM

Make sure that you are using the 16 bit depth and not 24. You display is only capable of 16 bit. Other than that, maybe you are using the wrong video device driver, or your horizontal or vertical settings are off.

Perhaps you need to use one of the xorg.conf options, but I don't really know which one.
You might try:
Quote:

Option "NoMTRR"
Disables MTRR (Memory Type Range Register) support, a feature of modern processors which can improve video performance by
a factor of up to 2.5. Some hardware has buggy MTRR support, and some video drivers have been known to exhibit problems
when MTRR's are used.
in the screen section.

If it doesn't fix the problem then comment it out.
Also read through your /var/log/xorg.0.log after it happens. It might indicate what the problem is.
