Out of Frequency in Envision Flat 17" Monitor
 

I installed FC6 in a brand new computer. During the installation all was perfect, but when loading fedora for the first time the message of "Out of Frequency" appears in my monitor (Envision 17" Flat Monitor). Can somebody tell me what am I missing in the settings?

I had this exact same problem on a conventional Phillips 107S CRT monitor when I installed FC6.

I solved this by booting from the FC6 rescue CD and setting the runlevel to 3 (so that GUI mode is disabled on boot). I then downloaded the latest NVidia driver and had the installed patch my Xorg.conf so that it (supposedly) no longer listed the "unreachable" mode. My system started working fine then.

Apparently, FC6's Xorg setup file by default tries to go to too high a monitor frequency / resolution - and this is common? I thought only I had had this problem due to my monitor being 2 or 3 years old and not the current leading edge, i. e. FC6 tried to behave as if I have a modern, high-frequency capable monitor.

I'm gonna try it.

I'm new at linux. I only took a course in college of unix, but just in terminal or console level. If I can fix this with the info you gave me, I'll consider you my hero. :D

Still having problems with out of frequency
 

I need someone to be very specific in helping me fixing the "Out of frequency" error. I don't know a thing in changing setting in linux. I only know how to install fedora 6 or red hat 9. I downloaded the fedora rescue cd but can't find where to low the run level or the resolution settings. Can someone help me please!!!

Not sure exactly what model you have but check the product specs on your monitor

http://www.envisiondisplay.com/suppo...t&SMenu=manual

Find out the exact Horizontal Sync and Vertical Refresh rates it supports


Boot back into run level 3

hit the "A" key at the grub prompt where it lists the kernels..then type "3" at the end of the kernel line

Then edit /etc/X11/xorg.conf



HorizSync xx.0 - xx.0
VertRefresh xx.0 - xx.0

Change that to your monitor specs according to the manual

I like to do this after editing any X related stuff

Look for anything that says [EE]. If you don't see any ....your good!

when your done go back to runelevel 5

gdm login screen should pop up


Hope that helps some

Out of frequency
 

I typed 3 at the end of the kernel line and does the same thing: "Out of frequency". How I change to runlevel 3? I know how to edit the xorg.conf but can't do it if I can't get to the shell.http://linuxquestions.cachefly.net/i...milies/cry.gif

Suggestion:
Just boot as you always do. When boot is complete, press <ctrl><alt><F1>; you will be taken to a terminal where you can login. Login as root and fix the Xorg config. Switch to the GUI <ctrl><alt><F7> end press <ctrl><alt><bksp> to restart the X server.

PS I assume that you only have the problem in the GUI

Out of Frequency
 

Finally made it. Thanks to all of you for the help.

Maybe you can enlighten us how you fixed it. It can be usefull for others with the same problem.

Out of frequency
 

Ok, sorry, my mistake not telling it.

After installing FC6 and booting it for the 1st time, at the first moment the message of "Out of frequency" appears, I hit CTRL+ALT+Backspace to return to the loading process. It continues with other asking settings (that are only asked the first time of installing FC6) and then it goes to "Out of Frequency" again. At that time I hit CTRL+ALT+F1 to enter in text log in.

Then logged in as root. After logging in, change the directory to /etc/X11

# cd /etc/X11
<PRESS ENTER>

I used emacs as text editor to edit the xorg.conf file:

# emacs xorg.conf
<PRESS ENTER>

I looked for the subsection "Display" and add this line:

Modes "1024x768"

to save and exit emacs press CTRL+X and CTRL+C separately then answer "y" (Yes) to the question of "Saved and exit emacs?" and press Enter.

I hit CTRL+ALT+DEL to see it all from the beggining since the "Out of Frequency" message appeared in two different parts of the loading process.

End of Story :D

What did you use for your hsync and vsync settings?

I bought this LCD for my parents for Christmas (H7 I believe is the model number) and there was NOTHING in the manual about sync settings. They're obviously different than the ones for the 17" Sony Trinitron that would only turn on 1 out of every 5 times you pressed the switch, but without knowing what to change it to, I'm afraid of messing with them. (I've destroyed more than one CRT by having the wrong settings.)

I already tried tech support, AKA ground squirrels who type. They finally responded to me after a week of waiting and then just e-mailed me the useless manual that came in the box. (~2 meg on a dial-up connection; I was downloading for about 20 minutes and then found out it was nothing but instructions on how to connect the monitor to the PC in half a dozen languages!!! ARRRGGGGGHHHHH!!!!) There's also nothing on their site in the specifications for this monitor that I was able to find.

You could try the above. I have no personal experience with it but... I had to get creative with a similar problem with an envision monitor when I switched to linux. No decent specifications could be found in the manual, download, etc. The CD had an .inf file for windows. Luckily that machine was dualbooting 98SE and I used a little freebie windows utility (name escapes me now)similar to the above and used the results from that for the sync rates in X's config file.

That's a really good idea Nishtya. I'll load up the .inf in windoze and see what I can see in there. :)

Well if there is nothing in the inf that is helpful, try the utility in linux or windows that I linked to. I have bookmarked it for future reference.

Monitors have been pita for me sometimes, even in windows I had a Compaq monitor that I have to keep the mfr's setup on a floppy. Nothing can probe that one.

oops - I just realized you aren't the OP and we kind of hijacked the thread. Please pardon.

To Ruler2112:

I didn't use the horizontal and vertical syncs, I just add the line:
Modes "1024x768" in the Subsection "DISPLAY", and saved the xorg.conf file.

I looked for the Hsync and Vsync in my monitor's manual but I didn't have to use them.

Since I'm new at this you should ask Wim Sturkenboom (see all threat) if you need more support.
