FYI: FreedomStudio was unable to switch perspectives due to a “no more handles” error in FreedomStudio/Eclipse when running on Fedora 26:
…
org.eclipse.swt.SWTError: No more handles
at org.eclipse.swt.SWT.error(SWT.java:4559)
at org.eclipse.swt.SWT.error(SWT.java:4448)
at org.eclipse.swt.SWT.error(SWT.java:4419)
at org.eclipse.swt.graphics.Cursor.(Cursor.java:173)
…
Turns out I had to add:
–launcher.GTK_version
2
to my FreedomStudio.ini.
