User Image Dell G15 dual monitor problem May 14, 2024, 10:23 p.m.

1) Upgrade kernel higher than 5.15.76 because TigerLake drivers added to the kernel after that.
2) With non-free drivers of nvidia

2-a) if kernel is 6.x family add ibt=off to the kernel parameters within grub config and run update-grub

2-b) if hybrid mode runs with nvidia-prime then intel becomes primary monitor. So you cannot reach the HDMI output. To fix this you must set prime mode to nvidia.

This project helps this on Manjaro:

User Image SSH Tunnel May 4, 2024, 10:14 p.m.

Here is to step by step how to create an ssh tunnel and bind browser on it:

1) Create a tunnel by using SSH Dynamic Port Forwarding

Assume that our remote ssh server's IP is and the remote port is 2525 (default is 22)
Also i am using private-public key pair to communicate with my server.

We must run

ssh -q -C -N -D 9001 user@ -p 2525&

-q: quiet

-C: compress

-D: Dynamic port (this will set our connection as socks proxy)

-N: tells ssh not to try reading a command from standard input which, being connected to /dev/null, would return EOF and thereby terminate the tunnel immediately.
& : means send process to background and bind the process to init (not ssh spesific)

Note: You must put this shell piece into a bash file and autostart with your desktop if you want to stay connected all the time

Now we have a socks proxy running on our local machine.

2) Now it is time to configure your browser:

You can connect to local socks server by adding a socks proxy in your browser's proxy configuration but i dont prefer that always. So I prefer to use that plugin to connect my server whenever I want.

Here is the link of plugin ->https://chromewebstore.google.com/detail/proxy-switcher/iejkjpdckomcjdhmkemlfdapjodcpgih

Now configure it as below and voila!

User Image journalctl Jan. 22, 2023, 7:58 p.m.

List boots

journalctl --list-boots

Logs of a previous boot

journalctl -b -1

-b -1 means boot logs of -1 index of boot list

Errors since boot

sudo journalctl -p 3 -xb

-p 3 means priority err

-x provides extra message information

-b means since last boot


  • 0: emerg
  • 1: alert
  • 2: crit
  • 3: err
  • 4: warning
  • 5: notice
  • 6: info
  • 7: debug

Logs of spesific daemon from a previous time

  1. journalctl -u nginx.service -u php-fpm.service --since today


--since 09:00 --until "1 hour ago"

Display Kernel Logs

  1. journalctl -k

No Pager

  1. journalctl --no-pager

Tail Like

-n and -f works just like in tail


Get disk usage

  1. journalctl --disk-usage


  1. sudo journalctl --vacuum-size=1G

  1. sudo journalctl --vacuum-time=1years


  1. sudo mkdir -p /var/log/journal # if you planning to make it persistent to see previous bot logs
  2. sudo nano /etc/systemd/journald.conf

#Storage=auto # make persistent if you want to keep logs
SystemMaxUse=100M # max size of logs

User Image PyQt5 qthread example April 12, 2020, 5:08 p.m.

We are creating a worker.py file wihch is our threaded part:

# worker.py
from PyQt5.QtCore import QThread, QObject, pyqtSignal, pyqtSlot
import time

class Worker(QObject):
    finished = pyqtSignal()
    intReady = pyqtSignal(int)

    def procCounter(self): # A slot takes no params
        for i in range(1, 100):


And the main window part which is our main thread running in main.py file

# main.py
from PyQt5.QtCore import QThread
from PyQt5.QtWidgets import QApplication, QLabel, QWidget, QGridLayout
import sys
import worker

class Form(QWidget):

    def __init__(self):
        self.label = QLabel("0")
        # 1 - create Worker and Thread inside the Form
        self.obj = worker.Worker()  # no parent!
        self.thread = QThread()  # no parent!

        # 2 - Connect Worker`s Signals to Form method slots to post data.

        # 3 - Move the Worker object to the Thread object

        # 4 - Connect Worker Signals to the Thread slots

        # 5 - Connect Thread started signal to Worker operational slot method

        # * - Thread finished signal will close the app if you want!
        # self.thread.finished.connect(app.exit)

        # 6 - Start the thread

        # 7 - Start the form

    def initUI(self):
        grid = QGridLayout()
        grid.addWidget(self.label, 0, 0)

        self.move(300, 150)
        self.setWindowTitle('thread test')

    def onIntReady(self, i):
        # print(i)

app = QApplication(sys.argv)

form = Form()


The only connection between worker and main is via emit and pyqtSignal. This is the critical part (çokomelli)

1) Be sure you are a member of the lp group . İf not :

sudo gpasswd -a YOUR_USER lp

then relogin or reboot

2) Then install capt-src from aur

i used yay for it. An be sure cups installed as a dependency of capt-src

yay -S capt-src
sudo pacman -S cups

3) Enable and check cups

systemctl start org.cups.cupsd.service
systemctl status org.cups.cupsd.service 
# At this point you must see "active" status without errors as an output. 
# If you see some errors that means that you are missing something
# After everything goes well enable the service permenantly
systemctl enable org.cups.cupsd.service

4) Check where is your printer rested. In py pc it is on lp1

ls /dev/usb/lp*

5) Enable and check capt

sudo /usr/sbin/lpadmin -p LBP2900 -m CNCUPSLBP2900CAPTK.ppd -v ccp://localhost:59687 -E
sudo /usr/sbin/ccpdadmin -p LBP2900 -o /dev/usb/lp1 # lp1 is our printers port that we checked before
sudo systemctl start ccpd.service
sudo systemctl status ccpd.service # Status must be active without any errors
sudo systemctl enable ccpd.service

6) If everything goes well you must see "Redy to print!" mesage after below lines

captstatusui -P LBP2900 


Note: Restarting or relogin is important after you add yourself to the lp group
