In my previous article I explained how to install Ubuntu in a LXC container. But once a Gentoo user, always a Gentoo user. So lets see how to install Gentoo inside of a LXC Container from a provided template. The installation part is exactly the same as it was for Ubuntu. The only difference is at the lxc-create command, you select Gentoo stable here ;). So if you did not install your SSD yet and do not know anything about the lxc-create command, read about it here! First steps to a usable Gentoo Container If you already tried to attach your newly created container, you should have noticed you have…

Creating a LXC Ubuntu container in OpenWRT on a Turris Omnia

Preparing the disk To be able to run virtual systems on your Router you will first need to provide more space. This can be done by attaching an external harddisk using the USB ports or on a NAS for most routers. But for the Omnia, there is a other better way. You can insert a mSATA drive inside of it. The router has 3 PCIe slots. Only the one in the center of the board is able…

Add Unlisted screen resolution using xrandr
The problem On my desctop computer I have 2 ultra-wide-screens from LG, one connected with HDMI, the other with DVI. The HDMI screen works fine out of the box but the DVI screen gets recognized as a normal wide-screen. After some googling I found the solution to add the resolution manually to my Linux system. Getting the right configurations using xrandr first run $ xrandr this will give output like this: Screen 0: minimum 320 x 200, current 5120 x 1080, maximum 8192 x 8192 HDMI1 connected 2560×1080+2560+0 (normal left inverted right x axis y axis) 677mm x 290mm 1920×1080 60.00* 1680×1050 59.88 1600×900 59.98 … HDMI2 connected 2560×1080+0+0 (normal…

Luckily there is something called OCR (Optical Character Recognition). With this technology it is possible to extract text out of images. The most popular application to do this in Linux is tesseract. But looking at its man page, we immediately see 1 big problem… it does not work on PDF files! Get rid of the PDF format So the first thing we have to do is to dispose of the pdf format and adopt the tiff format. This is very simply done…
