Re: Is Cygwin X server causing ubuntu eclipse to copy to the clipboard on selection?

I asked about this on the eclipse forums, and they said Ubuntu Eclipse doesn't do this, and it's likely being done by my X server. Yes, the X server is copying the selected text to the Windows clipboard. Let me try to explain why: X supports an arbitrary number of 'selections', the two of interest here are the PRIMARY selection (which conventionally contains some data which the user has selected) and the CLIPBOARD selection (which conventionally contains some data that the user has explicitly requested to be 'copied' to the clipboard) The Cygwin X server monitors these selections for changes, and makes text in the most recently changed one available for pasting from the Windows clipboard. So, if you select some text in eclipse after copying some text to the clipboard, you will get the selected text, not the copied text, when you paste in Windows. I can understand this behaviour is confusing to people who are expecting the X clipboard to behave like the Windows one. It has been suggested a few times that we should not monitor the PRIMARY selection, but some very popular X applications (such as xterm and emacs) only use the PRIMARY selection by default. It's also been suggested that monitoring the PRIMARY selection should be configurable somehow, but I'm not sure that a global configuration option would lead to very useful behaviour.

Re: XWin 1.12.1.0 seg faults on startup?

This is a new install of Cygwin/new install of Win7 on an AMD x64 system with an Nvidia gtx-570 GPU; I've reinstalled the X components a couple of times; rebasedall a couple of times. The log (I installed an XWin.exe w/symbols) says: [ 5306.810] winPositionWindowMultiWindow: (x, y) = (0, 0) [ 5306.810] immediately return since hWnd is NULL [ 5306.810] winMapWindowMultiWindow - pWin: 80062268 [ 5306.810] winUpdateWindowsWindow [ 5306.810] winReshape () [ 5306.826] Segmentation fault at address 0x0 So, this looks like maybe it's failing while trying to create a window, so this might be a timing condition at startup. You might try creating an empty ~/.startxwinrc (so the default xterm is not started by startxwin) and see if that makes a difference? -- Jon TURNEY Volunteer Cygwin/X X Server maintainer -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://x.cygwin.com/docs/ FAQ: http://x.cygwin.com/docs/faq/

If so the you can look at http://x.cygwin.com/docs/faq/cygwin-x-faq.html#q-ssh-no-x11forwarding Yes it is a Unix cluster. A2 worked, but Matlab is approx. 60 times slower than normal - or even worse. Can this be solved? If the slowdown is in drawing, it might be due to the fact you are not getting hardware accelerated OpenGL. To get this with the Cygwin X server currently (1) You must be using multiwindow mode, and (2) you must 'export LIBGL_ALWAYS_INDIRECT=1' on the remote machine. See [1].

It's also been suggested that monitoring the PRIMARY selection should be configurable somehow, but I'm not sure that a global configuration option would lead to very useful behaviour. I just verified that I can easily configure Emacs to not copy to the clipboard on selection, and to replace the selection on yank. It's unfortunate that I can't directly configure Eclipse to do this, but I would be surprised if they would have thought to implement this, as Eclipse normally works the way you expect on both Ubuntu and Windows. It's only when displaying the Ubuntu window on Windows through Cygwin that it behaves unconventionally. -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://x.cygwin.com/docs/ FAQ: http://x.cygwin.com/docs/faq/
