Убрал частоту и всё сработало...
cvt 1368 768 85
cvt 1368 768

xorg.conf снёс нафиг.
pztrn
А может KVM принимает максимум 1024х768? Что в EDID у него? Какой KVM?
Не, этот же системник из винды на монитор нормально передаёт в 1366x768. EDID от него нету... :-(
Morisson
Попробуй добавить
Option "UseEDID" "false"
в xorg.conf
И повторить команды
Ничего не изменяется.
Товарищи! Помогите решить проблему, а то я уже не знаю куда копать...

Железо:
Видеокарта Nvidia GeForce GTS 250
Монитор AOC n941sw

Установленные пакеты
nvidia-340xx
nvidia-340xx-utils
lib32-nvidia-340xx-utils

Проблема
При подключении монитора напрямую к видеокарте выставляется разрешение 1366х768, всё правильно, всё хорошо.
При подключении монитора через KVM Switch, система не распознаёт монитор, поэтому не может выставить нормальное разрешение (выставляется 1024x768

Попытки добавить новый режим к xrandr успехом не увенчались.

Попытка при подключенном мониторе силами nvidia-settings создать xorg.conf и подсунуть его к KVM тоже не даёт результата.

ЧЯДНТ? Как его научить нужному разрешению?
Здравствуйте, форумчане!
Подскажите, ЧЯДНТ?

Цель: настроить https
Проблема: с помощью certbot certonly получен сертификат, но прикрутить его к apache не получается.

Здравствуйте, арчеводы!

Помогите решить проблему: есть arduino uno r3, установил пакет arduino, запустил, набросал простенький скейтч
/*
First Program
 */

int ledPin = 13;

void setup() {
  // put your setup code here, to run once:

  // initialize pins as outputs
  pinMode (ledPin, OUTPUT);
}

void loop() {
  // put your main code here, to run repeatedly:

  digitalWrite (ledPin, HIGH);
  delay (1000);
  digitalWrite (ledPin, LOW);
  delay (1000);
}
В настройках выбрал плату Arduino/Genuino Uno, порт /dev/ttyACM0 (Arduino/Genuino Uno)

Все просто... Если установить ForeignKey без параметров:
HINT: Add or change a related_name argument to the definition for 'Messages.user_2' or 'Messages.user_1'.

Вот работающий пример (first_app/models.py):
from django.db import models

# Create your models here.

class Users (models.Model):
  class Meta ():
    db_table = 'users'

  id   = models.AutoField (primary_key = True)
  name = models.CharField (max_length = 50)
  mail = models.CharField (max_length = 50)

class Messages (models.Model):
  class Meta ():
    db_table = 'messages'

  id     = models.AutoField  (primary_key = True)
  text   = models.TextField  ()
  author = models.ForeignKey ('Users', db_column = 'author', related_name = 'author')
  user_1 = models.ForeignKey ('Users', db_column = 'user_1', related_name = 'user_1')
  user_2 = models.ForeignKey ('Users', db_column = 'user_2', related_name = 'user_2')
Тогда в БД создаётся именно то, что нужно.
И да: Тыц
В моём случае: СУБД - mysql

Т. е. СУБД позволяет создать в таблице два поля, являющиеся внешним ключом на одно и то же поле другой таблицы. Сейчас с django поэкспериментирую...
А что означает
svicer
не зависят от этого материала и не наследуются им
?
Если пользователь должен быть зарегистрирован - тоже установить связь ForeignKey... Может я что-то неправильно понял?
