Xorg - adding undetected resolutions

source

Due to buggy hardware or drivers, your monitor's correct resolutions may not always be detected. For example, the EDID data block queried from your monitor may be incorrect.

If the mode already exists, but just isn't associated for the particular output, you can add it like this:

• $ xrandr --addmode S-video 800x600

If the mode doesn't yet exist, you'll need to create it first by specifying a modeline:

• $ xrandr --newmode <Mode``Line>

You may create a modeline using the gtf or cvt utility. For example, if you want to add a mode with resolution 800x600 at 60 Hz, you can enter the following command: (The output is shown following.)

• $ cvt 800 600 60
  # 800x600 59.86 Hz (CVT 0.48M3) hsync: 37.35 kHz; pclk: 38.25 MHz
  Modeline "800x600_60.00"   38.25  800 832 912 1024  600 603 607 624 -hsync +vsync

Then copy the information after the word "Modeline" into the xrandr command:

$ xrandr --newmode "800x600_60.00"   38.25  800 832 912 1024  600 603 607 624 -hsync +vsync

X tuning

Some useful software for low level tuning X

xprop - WM classes and etc
xwininfo - window id*, position, style, owner and etc

 * xkill -id window_id_from_xwininfo

quote

You say you love rain, but you use an umbrella to walk under it.
You say you love sun, but you seek shelter when it is shining.
You say you love wind, but when it comes, you close your window.
So that's why I'm scared when you say you love me.

small notes about django and etc

source 

Just to remember, how to get project bse directory in django projects: 

settings.py
import os
# Build paths inside the project like this: os.path.join(BASE_DIR, ...)
BASE_DIR = os.path.dirname(os.path.dirname(__file__))
print(BASE_DIR)



# How to tell django ignore requests like /favicon.ico and etc.

settings.py

import re
IGNORABLE_404_URLS = (
    re.compile(r'^/favicon\.ico$'),
    re.compile(r'^/robots\.txt$'),
)


# How to serve static files in dev

settings.py

import os
BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))

STATIC_URL = '/s/'
STATIC_ROOT = ''
STATICFILES_DIRS = (
    os.path.join(BASE_DIR, 'static'),  # <- only one static files directory
)



Some magic in widget configuration
