Titel: Background KDE Desktop displays size 15" in 17"LCD

Hello,
First time having this problem after new HD installation:
My 17 inch.screen leaves Top & bottom unused black color horizontal bands spaces;
That means :
When I am looking at the LCD screen, I cannot adjust or stretch
the size of the background KDE Desktop to the size of the monitor!!
Even with the built-in touch MENU (auto adjust) on the frame monitor!

It's like having a 15" screen or even less on a 17" screen LCD monitor!!
Thanks for a cure to this trouble
rokhvin.

Hi ,
Tried to #change-res as stated in the Help Faq, nothing seems to adjust my background KDE;
So, no luck to solve that..

I've seen that problem on two different dell's I've tried installing kanotix onto, I don't know the solution, I just gave up since I was just testing to see if I could install onto the dell.

What video chipset/card do you have?

some of the monitors did not use the OVERSCAN function by default. Some can't use this function. Mostly old CRT's price-range 65 to 129$. Dell uses this type of monitors with their low-budget PC's.

@rokhvin, my be you have a fixed-freq. Monitor which will adjust only the timing of the signals, not the width and hight of the the screensize.

To proof this. use the statup-screen as a reference size is 1024x768 and should fill the whole screen with no borders.

Next use the cheat hsync=76.5 vsync=75, than login as usual. Does the Background now fill the whole screen?

Hello to everyone of you,

So, h2 , my case is a Viewsonic LCD 8ms that is a free replacement factory from the original monitor due to ultrasonic bips sounds when screen was set idle.The replacement monitor
is free from that weird bips but maybe an other trouble!

So, eco2geek, I have a Matrox G200 MGA chipset I think;This is not the 1st time I am
installing kanotix to HDD(the last 3 times installations, never had such trouble)

So, schnorrer, my screen even at 1280x1024 at kanotix boot with F4 choice resolution
never worked to fill the space!
I checked your set up advice:
"Next use the cheat hsync=76.5 vsync=75"---->on the boot menu with F4 1280x1024
I DIDN'T SUCCEED with the above cheat code, sorry.Same KDE background display!
Should I try other settings?!
Thanks for this attempt to solve that debilitating trouble,

rokhvin

on the Boot-menu-Line at the bottom that is the place to add the cheat-codes

/boot/vmlinuz root=/dev/hda1 ro ramdisk_size=100000 lang=de apm=power-off nomce vga=0x317 ### cheat-codes

If this helps you can add this in /boot/grub/menu.lst for every kernel-line.
The whole line looks like:

/boot/vmlinuz root=/dev/hda1 ro ramdisk_size=100000 lang=de apm=power-off nomce vga=0x317 srceen=1280x1024 hsync=76.5 vsync=75

This overwrites the X-Server-Settings. MGA-200-Chips with 8MB GraficsRam can do this.

Next what you can do. edit /etc/X11/Xorg.conf where the modlines should removed completely.
In Section Monitor you should exchange the former settings pointing to ultrasonic by those with the settings what the Viewsonic can do.

the Rest of the file is ok.

Well, I made the /boot/grub/menu.lst modification (very interesting), but, sorry,
your hsync & vsync settings didn't help yet; Are you sure these are the right ones?

And for "edit/etc/X11/Xorg.conf" I had only this line:
/etc/X11/Xorg.conf [-M--] 0 L:[ 1+0 1/ 6] *(0 / 5b)= . 10 0x0A
What should I do, please?

Thanks anyway
rokhvin.

To edit xorg.conf open Konsole and enter:

Code:

sux

mcedit /etc/X11/xorg.conf

Hi Ockham,

Thanks a lot for your precise command; I got it.
I will be able to erase the modlines for my trouble.
Thanks again,

Hey schnorrer,

Well, I did exactly what you suggested:
- /boot/vmlinuz root=/dev/hda1 ro ramdisk_size=100000 lang=de apm=power-off nomce vga=0x317 screen=1024x768 hsync=76.5 vsync=75
then:
- Next: edit /etc/X11/Xorg.conf where the modlines should removed completely
But, NOTHING changed, I am sorry.
I have to tell you: on LiveCD, I had the same display trouble; Adding at the boot "noml"
resolved the problem!! liveCD only!? Supertip from kano (IRC)
Do you have a better idea, please?
Thanks.

My display badly fitted from last installation is eventually SOLVED!

Just use liveCD with options "noml" & "highest screen res (screen=xxxx)" to :
mount /media/root partition HD
cp /etc/X11/XF86Config-4 /media/root partition HD/etc/X11/xorg.conf
overwrite: y
umount media
then on HD inst. modify boot menu optios with your settings!!
That's it;
Thanks REALLY to Kaaaano!!(IRC) First and then to schnorrer close to solve
& also ockham23.
rokhvin. Sehr glücklich

I've wondered if that would work or not, it's good to see it does, I wasn't sure how different xorg.conf and the older xf86.conf stuff was.

eco2geek - 16.07.2006, 20:46 Uhr

Doesn't the LiveCD still use an "/etc/X11/XF86Config-4" config file, instead of one named "xorg.conf"? And it's equivalent?

yes, as far as I know it does, but I guess the syntax is the same

I don't own any dells, I just remembered this when I was testing two different ones, if a dell walks into my house you can rest assured that it will walk right out as soon as humanly possible. But it's good to know the stuff in general.
