Hello. After reinstalling on Ubuntu, there were problems with Qt.
When building a project in the Build Console, the following crashes:

/opt/Qt/5.10.1/gcc_64/bin/qmake -o Makefile ../MyProject/MyProject.pro -spec linux-g++ CONFIG+=debug CONFIG+=qml_debug
g++ -Wl,-rpath,/opt/Qt/5.10.1/gcc_64/lib -o MyProject main.o moc_widget.o   -L/opt/Qt/5.10.1/gcc_64/lib -lQt5Widgets -lQt5Gui -lQt5Core -lGL -lpthread 
/usr/bin/x86_64-linux-gnu-ld: cannot find -lGL
collect2: error: ld returned 1 exit status
Makefile:249: recipe for target 'MyProject' failed
make: *** [MyProject] Error 1

Please tell me what is the problem?

At the same time, I recommend checking the drivers for the video card.
