I am fed up with the default Windows interface so I decided to install Cygwin and run a gnome shell on startup.

When the installation was done, I went into Cygwin and started X with this command xinit gnome-session and I got this error and the shell closed shortly thereafter.

Screenshot of gnome error

and this is the output log

I think it has something to do with display drivers but I really don't know when I was installing Cygwin it came up with an error but stupidly I pressed OK without reading it, so help.

    For textual output, copying the text is far more beneficial for us than screenshots.

Reset to default

To run the the Xserver with the window manager in cygwin use:

startxwin

and if you need to disable the WGL accelerator

startxwin -- -nowgl

See https://x.cygwin.com/docs/ug/using.html#using-starting for details.

Message

libGL error: Screen is not Windows-DRI capable

indicates that we wanted to use direct, hardware-accelerated OpenGL ('Windows-DRI'), but that the server didn't allow it.

This could be due to:

  • server option -nowgl
  • windowing mode doesn't permit wgl (i.e. not -multiwindow)
  • display driver does not support WGL (i.e. the default VGA driver)

etc.

More info.

Try run with -multiwindow:

xinit gnome-session -- -multiwindow
