I use Ubuntu 16.04.2. I installed xrdp and xfce4 according to this page. It was OK and I ran some program remotely.
Then I installed some programs on the system such as CUDA 8.0, Oracle Java, openssh, vsftpd...
But now I cannot open installed program in remote session. For example when I run Nautilus a window appears and says:
Failed to execute default File Maneger.
I tried to run nautilus via terminal but it failed and the following error massage appeared:
Segmentation fault (core dumped)
I also tried to run Firefox via terminal:
ExceptionHandler::GenerateDump cloned child 26648 ExceptionHandler::SendContinueSignalToChild sent continue signal to child ExceptionHandler::WaitForContinueSignal waiting for continue signal... Segmentation fault (core dumped)
I tried MATE desktop, but the problem recurred.
Any help would be appreciated.
