Frequency Out of Range

I've just been trying to install Ubuntu. (New to linux.) All seems to be going quite peachy, and it gets to a point after anaconda asks you to remove the CD and reboot; once it finishes the installation, I think. This is a little bit after it asks you to select which resolutions you want to be usable by the X window system; I chose the defaults; only 1024x768, 800x600 and 640x480. What happens, is that nothing can be displayed on the monitor. The monitor comes up with a message that says "80.8KHz/154.1Hz / Freqency out of range / Try other resolutions". At this point, goes directly to that whenever I try to boot from the hard drive, so I have to try to reinstall. My question, is why is this happening? And obviously, how do you s'pose it can be fixed? I've dismissed the possibility that the monitor can't handle 1024x768 or something, but perhaps that's the case? Any help would be the awsome. PS- Line breaks aren't happening automatically, as it says. This is just temporary?

refresh rate

I think your monitor can handle the resolution of 1024x768 (as most do), but the refreshing rate of 80.8KHz/154.1Hz must be too much. Isn't there a way to manually configure it to let's say max. 100Hz? I'm not sure as I use a TFT, which doesn't use refresh rates.


Yeah, I think that's what I'm actually looking for. A way to reconfigure the refresh rate. Don't suppose that someone could think of a way of doing that, considering that I don't have a working operating system on the computer at this time?

This should help.

I think you would have to either look in your monitor manual or google up some information on your monitor refresh rates.  Having done so the instructions for editing your xorg.conf can be found here. Editing your xorg.conf might be a bit of task for you if you are new to linux, so a different way you might approach it is to do this command from the command line (if you can find a command line and login with your username and password). sudo dpkg-reconfigure xserver-xorg This will reconfigure your xorg.conf file.  Just choose the default options for anything that you don't know the answer to.  Try selecting a lower resolution perhaps so that you can at least get a working desktop environment.  From there you could troubleshoot a bit more to get the system up and running the way you want it to. (The formatting on this is pretty mucked up.  On my end it shows it all nicely spaced out and relevent stuff marked in bold, but it won't post that way unfortunately)

Can't do those things, though.

The problem, is that I can't do anything, because of the problem. I can't really access a command line, because the monitor won't display anything. Also, the monitor didn't come with a manual. I've played around with the controls, but there doesn't seem to be a way to set the refresh rate from there. The only things I can control, I think, are things that're before the installation finishes. Maybe my monitor is just terrible. Maybe I should try a different monitor. Maybe I can trade it in for another at the store.

My memory of the

My memory of the installation process is rather vague, but do you get a choice to use a lower screen resolution during install?

Now, a new problem.

Yeah, you do. ... Edit: So, that doesn't happen anymore if the resolution is set lower, but something else does. I get what appears to be a blank black screen with a command line cursor, but no text. And, nothing happens when I type anything. As it happens, this is exactly the same thing when I had tried to install SuSE, earlier. I'm thinkin' that this might be something to do with the hardware possibly. Anyway, I'm not reeally asking for help with this here, but if anyone has an idea about why it is, do tell.

Change the monitor

Change the monitor

Hehehe..succinct and to the

Hehehe..succinct and to the point. :) It's very true though.  This particular monitor you are using sounds like real problem.

try this

1) first note down the VF and HF ranges that appear on the monitor when it goes blank. 2) press Alt+F2. That should give you a command line. 3) login with root 4) type the following: # Xorg -configure 5) a new file is created in your home dir. Open it with an editor. Go to the section "Monitor". You will find two attributes named "VertRefresh" and "HorizSync". Put the values that u had earlier noted down in the 1st step. Save and Exit. 7) Test by typing: # X -config ~/ if u get some screen with a moving mouse, then its working... 6) type: # mv ~/ /etc/X11/xorg.conf 7) reboot.... tell me if it works... or even if it doesn't....

in short

Just try changing the HorixSync and VertRefresh atributes in the "Monitor" section of /etc/X11/xorg.conf file. If u dont find those attributes, add them. Refer to the link given by Mustard. I'm sure its the problem with the refresh rates.

One problem though....

The one big problem though rockineagle is that he can't get a command line at all. :)

Frequency out of range with BQ FP71G+

I can report  an even more serious problem:during install I just see a completely blurred sceen. I tried other resolution and Frquencies, but nothing works clean. My Adapter is a good old Matrox G200. I thought this combination should work out of the box. I get through the install's almost undoable.Monitor: BenQ FP71G+Adapter: Matrox G200Any suggestions?

Out of range

When you start your machine you'll get a message like "press esc to enter the menu". Press escape.Next you'll see a menu with the different kernels that you can start.You can change the runlevel i.e. graphical or text login by adding a 3 to the kernel line.More information you can find here: If all things went well. you'll get a login prompt. login as user, next sudo -s to get a root shell next thing you have to do is reconfigure your xorg. You can do that with the next command:dpkg-reconfigure xserver-org (for more info look here: Test it with the command startx. If all is oke reboot and remove the 3.done. Good luck. edit | reply
