After install, resolution might be off. Xrandr might so something like this:
xrandr: Failed to get size of gamma for output default
Screen 0: minimum 1024 x 768, current 1024 x 768, maximum 1024 x 768
default connected 1024×768+0+0 0mm x 0mm

Step 1: Grub resolution is wrong (optional)

On a latest release of PostX Gnu/Linux contrib and non-free sources entries were accidentally left out. This will be fixed on later upcoming releases. For now you can add the following entries to sources list files:
deb http://deb.debian.org/debian bullseye contrib non-free
deb-src http://deb.debian.org/debian bullseye contrib non-free
deb http://deb.debian.org/debian bullseye-updates contrib non-free
deb-src http://deb.debian.org/debian bullseye-updates contrib non-free
deb http://security.debian.org/debian-security/ bullseye-security contrib non-free
deb-src http://security.debian.org/debian-security/ bullseye-security contrib non-free
Adding entries can be done manually by adding them into /etc/apt/sources.list. Alternatively, they can be added to file of your choosing under /etc/apt/sources.list.d directory structure.
For example you can make a file called patch.sh with the sources list content, as seen above, and make it executable with chmod +x patch.sh .
Finally, you can execute the patch.sh as follows: cat patch.sh > /etc/apt/sources.list.d/extra.list .
This will create a new file called extra.list under /etc/apt/sources.list.d folder. To apply changes to system, you still need to execute apt-get update. After this you are all done and new sources should be ready for usage.
During PostX Gnu/Linux RC2, I hit the following issue with RunIT-QT Browser.

Usually things go fine. You have your Openbox, Fluxbox, PekWM or Awesome etc. window manager running and everything scales up nicely. Sometimes you end up into a situation where you are not that lucky: window frames are too small and the desktop font is just too tiny – and you cannot even read the text properly.
Luckily, the previous issues are easy to fix. Usually, the root cause of them is that you have a big display and your window manager does not know how to size things correctly by itself. Another reason might be that you have changed your wires. For example, I replaced a broken old HDMI wire with a newer one and the issues appeared. You should edit your .Xresources file to apply changes to Gtk and QT programs alike. If you are only using GTK apps it might be a bit easier to change your DPI value via .Xdefaults file.
