I use PhpStorm. I use x2go and xpra for connect to remote machine with launched phpstorm.
If on terminal-system installed any desktop environment, exclude xfce4 - PhpStorm hotkeys work perfectly.
If installed xfce4 on terminal-system - some hotkeys in PhpStorm not work (Shift+F6, Ctrl+Alt+←, Ctrl+Alt+→)
On xfce4 window-manager and keyboard-manager turn off all keyboard shortcuts similar to PhpStorm hotkeys.
PhpStorm launched on xpra display on remote computer. Xpra session attached to x2go-session. My terminal computer connected to remote computer over x2goclient
