Problem with resolution

[Roger Chrisman]

You can get to a text consol by typing Ctrl+Alt+F1.

(You can get back to the graphical user interface later with Alt+F7. 
Ctrl is not needed to return to the GUI but is to exit the GUI.)

The text consol will probably display clearly. You can 
edit /etc/X11/xorg.conf (save an original copy first so that you can 
revert to it if you screw up the xorg.conf in any way which is really 
easy to do because the syntax is easy to get wrong).

Here are some things you might want to do if you decide to try this:

* Get some help up in another virtual consol:

Alt+F2 (<- keypresses, not text, and in virtual consol 2 type):

man xorg.conf

Alt+F1 (<- keypress to return to virtual consol 1 for some editing of 
xorg.conf. Jump between your work on xorg.conf in virtual consol 1 and 
the man page you opened in virtual consol 2 if you want. Alt+F3, Alt+F4 
etc. if you want more virtual consols to work in.)

* Make a backup copy of xorg.conf before you edit it:

sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf.ORIGINAL-but-blurry

* Edit xorg.conf (use another editor if you don't like vim):

sudo vim /etc/X11/xorg.conf

* To test your new xorg.conf you can reboot (or restart X but I don't 
know how to do that so I just reboot):

sudo reboot

* If you want to reinstate the original but blurry xorg.conf, save your 
current xorg.conf as work in progress if you want to and copy the 
original back:

sudo cp /etc/X11/xorg.conf  /etc/X11/xorg.conf.WORK-in-progress
sudo cp /etc/X11/xorg.conf.ORIGINAL-but-blurry /etc/X11/xorg.conf


I'm not an expert by any means but the above is how I tinker with my 
display settings.

I have a 21 inch Nokia 445PRO CRT monitor that flickers ever so slightly 
but annoyingly under the default xorg.conf configuration (from Kubuntu 
Breezy Badger for AMD64 installation). I edited my xorg.conf as follows 
and now it displays very nicely with no flicker (WARNING, your monitor 
probably requires other HorizontalSync and VertRefresh settings -- 
Google for them or look in your monitor manual. Incorrect settings I 
have read might damage monitor):

For Sections "Monitor" and "Screen" I now have:

Section "Monitor"
        Identifier      "Generic Monitor"
        Option          "DPMS"
        # Original:
        #HorizSync      28-51
        #VertRefresh    43-60
        # Roger:
        HorizSync       29-125
        VertRefresh     50-180
EndSection

Section "Screen"
        Identifier      "Default Screen"
        Device          "ATI Technologies, Inc. Radeon 9200 (RV280)"
        Monitor         "Generic Monitor"
        DefaultDepth    24
        SubSection "Display"
                Depth           1
                Modes           "1280x1024" "1024X768" "800x600"
        EndSubSection
        SubSection "Display"
                Depth           4
                Modes           "1280x1024" "1024x768" "800x600"
        EndSubSection
        SubSection "Display"
                Depth           8
                Modes           "1280x1024" "1024x768" "800x600"
        EndSubSection
        SubSection "Display"
                Depth           15
                Modes           "1280x1024" "1024x768" "800x600"
        EndSubSection
        SubSection "Display"
                Depth           16
                Modes           "1280x1024" "1024x768" "800x600"
        EndSubSection
        SubSection "Display"
                Depth           24
                Modes           "1280x1024" "1024x768" "800x600"
        EndSubSection
