[kde-linux] KDE Newbie needs help

[Suchit Jhunjhunwala]

First of all, you have written XF68Config-4 instead of XF86Config-4, which I
think is a typo. Just ensure you have the correct filename in your system.
I'm familiar with fedora, which uses xorg.conf instead of XF86Config-4, but
but things might be similar for debian. To verify whether your XF86Config-4
file is haveing any effect, read /var/log/Xorg.0.log or
/var/log/XFree86.0.log (whichever is the correct file for debian)

Do you have the line:
Option      "UseEdidFreqs" "true"
under Section "Device" in your XF68Config-4 file? If not try setting it to
true or inserting this line. Then restart x server and read the log. See
what refresh rates EDID reports in the log. For example in my log, these
lines are :
(II) NVIDIA(0):   HorizSync   : 30.000-75.000 kHz
(II) NVIDIA(0):   VertRefresh : 60.000 Hz
(II) NVIDIA(0):      (HorizSync from EDID)
(II) NVIDIA(0):      (VertRefresh from EDID)

If EDID reports a range of vertrefresh frequencies and still you don't get
resolution options for those frequencies, you can add your own. for example,
I have this section in my xorg.conf file:

Section "Modes"
        Identifier     "16:10"
        # 1680x1050 @ 60.00 Hz (GTF) hsync: 65.22 kHz; pclk: 147.14 MHz
        ModeLine     "1680x1050" 147.1 1680 1784 1968 2256 1050 1051 1054
1087
        # 1680x1050 @ 75.00 Hz (GTF) hsync: 82.20 kHz; pclk: 188.07 MHz

        # 1400x875 @ 60.00 Hz (GTF) hsync: 54.36 kHz; pclk: 100.46 MHz
        Modeline "1400x875_60.00"  100.46  1400 1480 1624 1848  875 876 879
906
        # 1400x875 @ 70.00 Hz (GTF) hsync: 63.77 kHz; pclk: 119.89 MHz
        Modeline "1400x875_70.00"  119.89  1400 1488 1640 1880  875 876 879
911

        # 1280x800 @ 60.00 Hz (GTF) hsync: 49.68 kHz; pclk: 83.46 MHz
        Modeline "1280x800_60.00"  83.46  1280 1344 1480 1680  800 801 804
828
        # 1280x800 @ 70.00 Hz (GTF) hsync: 58.31 kHz; pclk: 98.89 MHz
        Modeline "1280x800_70.00"  98.89  1280 1352 1488 1696  800 801 804
833

EndSection

Do you have such a section? You can add your custom resolutions and refresh
frequencies using gtf. For example, if you want to insert a modeline for a
resolution of 1280x800 at a refresh rate of 70 Hz, execute the following
command:
gtf 1280 800 70
U might get an output like this:
# 1280x800 @ 70.00 Hz (GTF) hsync: 58.31 kHz; pclk: 98.89 MHz
  Modeline "1280x800_70.00"  98.89  1280 1352 1488 1696  800 801 804 833
-HSync +Vsync

Copy the output ( I remove the -HSync +Vsync part) to the modes section. To
use your custom modes, u need to add these modes to the Section "Screen". My
screen section reads like this:
Section "Screen"
        Identifier "LaptopScreen"
        Device     "LaptopCard"
        Monitor    "LaptopMonitor"
        DefaultDepth     24
        SubSection "Display"
                Depth     24
                Modes    "1680x1050" "1600x1000" "1400x875" "1280x800"
"1152x864" "1024x720" "800x600" "640x480"
        EndSubSection
        SubSection "Display"
                Depth     16
                Modes    "1680x1050" "1600x1000" "1400x875" "1280x800"
"1152x864" "1024x720" "800x600" "640x480"
        EndSubSection
EndSection

Now when u restart X server and read the log again, it will tell u which
modelines were not usable if any modelines were not suitable for your
system.

btw, you can restart xserver by just pressing ctrl+alt+backspace. u will be
logged out and u'll have to log in again.
