How to force things in Linux.

X.org resolution

BEWARE: Make sure that your graphic card and your monitor support the resolutions you want to use. Otherwise hardware failure may occur!

In some cases X.org won't use the resolution you want and you know your hardware supports. Here is a way to force it. Adapt the snippet to your configuration.

Section "Monitor"
    Identifier  "Monitor0"
    HorizSync   31-101
    VertRefresh 60-160
EndSection

Section "Device"
    Identifier  "Card0"
    Driver      "YOURDRIVER"
    Option      "UseEDIDFreqs" "FALSE"
    Option      "UseEDIDDpi" "FALSE"
    Option      "ModeValidation" "NoEdidModes"
EndSection

Section "Screen"
    Identifier   "Default Screen"
    Device       "Card0"
    Monitor      "Monitor0"
    DefaultDepth 24
    Option       "NoVirtualSizeCheck"
    Option       "UseEDIDFreqs" "FALSE"
    Option       "UseEDIDDpi" "FALSE"
    Option       "ModeValidation" "NoEdidModes"
    SubSection   "Display"
        Depth        24
        Modes        "1280x1024"
    EndSubSection
EndSection

Things you should not do

What does this commandline do?

grep > *

Please guess before you read on.

Okay, let's test:

% ls -l
total 20K
-rwx------  1 xxx xxx  307 2008-10-16 09:44 test1.sh*
-rwx------  1 xxx xxx  112 2008-10-16 09:44 test2.sh*
-rwx------  1 xxx xxx  208 2008-10-16 09:44 test3.sh*

% grep > *
Usage: grep [OPTION]... PATTERN [FILE]...
Try `grep --help' for more information.

% ls -l
total 0
-rwx------ 1 xxx xxx 0 2008-10-16 09:46 test1.sh*
-rwx------ 1 xxx xxx 0 2008-10-16 09:46 test2.sh*
-rwx------ 1 xxx xxx 0 2008-10-16 09:46 test3.sh*

Obviously the '>' pipes nothing to all files '*' in this directory. Not nice if you don't have a backup.
