help a newbie with a resolution issue
 
extreme newbie here. just installed mandriva 10.2 SE on my system. got to the end of the install and had to reboot. when it tried to go into the GUI, the monitor gives me a message telling me the resolution is out of range. i searched the message boards and found similar probs. i tried to use xfdrake to correct it. tried many different settings, nothing works. its a cheap KDS monitor. the 1024 x 768 resolution works on windows. help me out linux people!

If you can get to the command line, maybe clearing out the xorg.conf and re-running XFdrake will help. Don't forget to test the settings before you're done.
For example:
Make a backup of the xorg.conf with this command:
Code:

cp /etc/X11/xorg.conf /etc/X11/xorg.bak
Clear out the original xorg.conf with this command:
Code:

>/etc/X11/xorg.conf
Run the XFdrake command to reselect monitor and resolution....
Code:

XFdrake
Test your settings.

didn't work for me
 
thanks for the idea, but it didn't seem to work. i've tried all resolution settings that work for windows. i've even tried another monitor (another cheap one).
i'm starting to think that this could be a vid card problem. the card i'm using is a radeon x600 (256mb pci-e). the setting it auto chooses is simply "radeon". i've tried the 2 below that (radeon fbdev and radeon fglrx) with no luck. also, should i choose xorg with 3d acceleration or not?

by they way, the exact monitor error message is "107.5khz/170.2hz frequency out of range" on the KDS Xflat 7b monitor and "out of range H:107.2khz V:170.0hz" on the envision monitor.

i need help!

Can you go back into XFdrake and select a generic monitor with lower resolution and lower HZ ?

rooster33 10-12-2005 07:27 PM

do you know what i should set as my horizontal and vertical hz? this is refresh rate, correct?

homey 10-12-2005 07:53 PM

Sorry, I don't know what it should be on your system. 107hz seems kind of high as it's usually around 60 to 70 for me.
Maybe you could get a livecd to detect the proper settings.
Also, you might be able to run the command: ddcprobe from a livecd.
On my box, ddcprobe puts out a lot of useful information.

If you look at xorg.conf, you will see all of the resolutions that will be selectable by the preferences route. On my system (Sony G400 monitor), the vert refresh shows a range of 48-120, but there are only 4 rates actually available when I try to change the setting thru preferences. I dont know what file these setting are in.

For starters, what options do you have when you do Preferences->Screen Resolution (or the equivalent on your system)

specs for KDS Download and store them in a safe place.
Edit the lines VertRefesh and HorizSync in the monitor section of your xorg.conf
Code:

HorizSync 30 - 70
VertRefresh 50 - 160

This should solve the problem.

The given specs can be found in the suer manual of the monitor. You did not specify which envision exactly, so you have to look for that yourself.

hey, thanks wim. i have played around with the xconfig a little bit, but it was pretty much all a guess. i'll have to try that when i get home from work today. i'll keep you posted.
