# Qt-based Scope
|
||||
|
||||
## Building Instructions
|
||||
For the new qt-based scope designed for NR, please consider the following:
|
||||
|
||||
1. run the gNB or the UE with the option '--dqt'.
|
||||
2. make sure to install the Qt5 packages before running the scope. Otherwise, the scope will NOT be displayed! Note that Qt6 does NOT work.
|
||||
3. To build the new scope, add 'nrqtscope' after the '--build-lib' option. So, the complete command would be
|
||||
|
||||
```
|
||||
./build_oai --gNB -w USRP --nrUE --build-lib nrqtscope
|
||||
```
|
||||
|
||||
## New Features
|
||||
|
||||
1. New KPIs for both gNB and UE, e.g., BLER, MCS, throughout, and number of scheduled RBs.
|
||||
2. For each of the gNB and UE, a main widget is created with a 3x2 grid of sub-widgets, each to display one KPI.
|
||||
3. Each of the sub-widgets has a drop-down list to choose the KPI to show in that sub-widget.
|
||||
4. Both of the gNB and UE scopes can be resized using the mouse movement.
|
||||
|
||||
## Troubleshoot
|
||||
|
||||
Similar as with the Xforms-based scope, you should allow root to open X
|
||||
windows if using Xorg:
|
||||
```
|
||||
xhost +si:localuser:root
|
||||
```
|
||||
|
||||
If you run on Wayland (e.g., Gnome on Ubuntu 22), you might get this error:
|
||||
```
|
||||
Warning: Ignoring XDG_SESSION_TYPE=wayland on Gnome. Use QT_QPA_PLATFORM=wayland to run on Wayland anyway.
|
||||
Authorization required, but no authorization protocol specified
|
||||
qt.qpa.xcb: could not connect to display :0
|
||||
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
|
||||
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.
|
||||
```
|
||||
|
||||
We have to force the use of Wayland. Before that, make sure that the Qt-Wayland
|
||||
plugin is installed. Also, there seems to be a problem with the qt5-gtk
|
||||
platform theme, so remove it:
|
||||
```
|
||||
sudo apt-get install qtwayland5
|
||||
sudo apt-get remove qt5-gtk-platformtheme
|
||||
```
|
||||
|
||||
Now, force the Wayland plugin; also make sure to pass `-E` to sudo:
|
||||
```
|
||||
sudo -E QT_QPA_PLATFORM=wayland ./nr-softmodem --sa -O <conf> --dqt
|
||||
```
|
||||
|
||||
Furthermore, if you get the following warning, _followed by a segfault_ (i.e.,
|
||||
if it runs, you can ignore this)
|
||||
```
|
||||
QStandardPaths: wrong ownership on runtime directory /run/user/1000, 1000 instead of 0
|
||||
```
|
||||
You can set the XDG runtime directory like one of the following options (try in
|
||||
order, keep `QT_QPA_PLATFORM` if necessary)
|
||||
```
|
||||
sudo -E XDG_RUNTIME_DIR=/run/user/0 ./nr-softmodem ...
|
||||
sudo -E XDG_RUNTIME_DIR=/tmp/runtime-root ./nr-softmodem ...
|
||||
sudo -E XDG_RUNTIME_DIR= ./nr-softmodem ...
|
||||
```
