Intrepid screen resolution limited choices

Asked by BrianO

I have read many different posts and have found nothing that will work.
I am also a first time user of this sort of OS.
I tried the FAQ "How to get better screen resolution" and got the following error when I typed "sudo apt-get install displayconfig-gtk".
ERROR: Reading package lists... Done
Building dependency tree
Reading state information... Done
Package displayconfig-gtk is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package displayconfig-gtk has no installation candidate

I can only select 2 resolutions, 800x600 & 640x480 and my monitor shows as unknown.
I have downloaded the monitor driver files from AOC's website and extracted them to a desktop folder.
This is a new installation of Intrepid on a PC that had only a newly formatted HD and no other OS on it.
Right now because of the resolution, I can not view some whole windows such as Transmission BitTorrent Client.

Then please also be sure your system is fully upgraded with no pending packages...

Open a Terminal from the menu Applications → Accessories → Terminal and type:
(when the system ask you a password give your user password, you will not see nothing when you type it, then press enter)

sudo dpkg --configure -a
sudo apt-get -f install
sudo apt-get --fix-missing install
sudo apt-get clean
sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade
sudo apt-get clean
sudo apt-get autoremove

Hope this helps

Just noticed another application that I cannot access all the functions due to the resolution and that is Evolution Mail. The "forward" button is not accessable to set-up the application.

Don't know how to contact someone, but I had originally had an I/O error during install that I could not find an answer on by searching. Just wanted to pass along that Nero express defaulted to "track-at-once" when burning the ISO and when I switched it to "disk-at-once", I was able to install without issue. Thought this may help with this issue but don't know where to post it.

To get access to other (hidden because they are out of the screen) parameter or buttons on a low screen resolution you always do this:

Press and keep pressed the ALT keyboard key and click with mouse (and keep clicked) into a window area you want to move then drag it....

hope this helps

 I experienced same problem after install. I had a 14" monitor connected. Solved problem when I connected a 17" Compaq 7500. Now I have more resolution choices than I need. I am using ATI 9550 with updated Linux driver.

I have solved a similar problem - running Intrepid under virtualization (KVM+hardy host), the virtual monitor isn't auto-detected anymore. Xorg then falls back to a safe default, which supports up to 800x600 due to the default HSync range.

A minimal /etc/X11/xorg.conf can solve the problem. Here are the entire contents of my new xorg.conf (formerly an empty file):

  Section "Screen"
    Identifier "KVM Screen"
    Monitor "KVM Host Monitor"
  EndSection

  Section "Monitor"
    Identifier "KVM Host Monitor"
    HorizSync 30-70
    VertRefresh 50-75
    # 'man xorg.conf' says you can set the pixel clock in KHz.
    # This is an UNTESTED example for 10-110 MHz clock:
    #Option "MinClock" "10000"
    #Option "MaxClock" "110000"
  EndSection

Replace the HorizSync and VertRefresh ranges with your monitor's actual capabilities. You can also use different identifier names if you want.

Under my new configuration, X starts at 1152x864, which seems to be the maximum 4:3 resolution that the emulated video card supports.

One other thing: you can edit xorg.conf by going to Applications -> Accessories -> Terminal, then running the command 'gksudo gedit /etc/X11/xorg.conf'.

Many thanks to Any_Key, marcobra and most of all Chad Daelhousen who solved the issue with a simple edit. Worked like a charm using the exact setting that you gave. I now have a full set of resolutions and choice of 3 refresh rates.

Thanks again,
Brian

Thank you so much Chad!! I have been pulling my hair out trying to figure out how to fix this. I'm seriously a beginner at this and your basic steps were completely helpful. I have been trying to fix this for weeks and just stumbled on your feedback. I could hug you right now! :-) Cheers!
