Setting fonts for remote gnome applications
I'm running some gnome applications on a Linux system and displaying on a remote cygwin/X server. Does anyone know how I configure the fonts used? The local gnome appearances applet just sets things for the local display. Are X resources used? I know this is more relevant to a gnome list but I did ask the question there and didn't get any answers. I'm hoping users here will have more experience with this situation.

RE: Mouse offset when using java swing based gui applications
Yes, my experience is the same as yours. The menus test starts with the
frame hidden off the top left, as before, but when I move the window,
the menus _do_ work OK.
Apps which set an initial location (add jframe.setLocation(400, 400);
after the pack() call) appear correctly and the menus still work.
Interestingly with the 1.7.3 XWin, the app would appear in the right
place but would tend to snap back to the top left if you tried to resize
the window. This does not seem to happen with the patched server.

Yes, I wasn't testing what I thought I was testing, and was completely
wrong
when I said sun bug #6434227 was fixed in the JRE that it claims it's
fixed in.
It's fixed in JDK1.7 and OpenJDK, but that bug lies when it says the fix
is in
1.6 as well.
However, it does identify what's going wrong. The significant
difference in
XDecoratedPeer.java between 1.6u21 and a fixed version is:

Location updates from ConfigureNotify are not processed in the NO_WM
case,
presumably causing the menus behave as if the window was still located
where
it was created.
There are 2 possible workarounds which occur to me:
(i) Lie and pretend we are a non-reparenting WM on the list that AWT
knows
about, like LG3D. This one of the workarounds suggested in the manpage
for
dwm (a non-reparenting, tiling WM)
Unfortunately, we have to tell a more lies to get AWT to accept this
lie, and
in particular, we have to claim to support EWMH, which the internal WM
doesn't
really (although it should), so I'm not too keen on this approach.
(ii) Alternatively, it's a straightforward workaround to add to the
internal
WM to cause it to send synthetic ConfigureNotify for these windows when
a
non-synthetic ConfigureNotify occurs.
From a quick test, this approach seems to work ok. But the Java window
still
appears with the frame off the top-left, rather than getting nudged away
from
the origin so the frame is visible, which is rather mysterious.
I've uploaded a build with this change at [1], patch to follow. Perhaps
you
could try it out and see if it works for you?

RE: Mouse offset when using java swing based gui applications
I've attached a small test case which shows the menu problems. Compile and run with: javac menus.java java menus My server configuration is Windows 7 x64, Cygwin/X X server version 1.7.3, with dual 1920x1200 monitors. I ran the test case on Fedora 12 x86, using the latest released JRE 1.6u21. The frame appears in one of two ways: 1. With the window frame off the screen top left - ie (0, 0) in the content area is at (0, 0) on the display Or 2. With the window frame showing, but as soon as I try to select a menu, the windows shifts to the position in 1. When the frame as off screen, (as in 1. above), the menus work fine; If I move the window elsewhere on the screen, the menus can be opened but you can't select any item. This menu behaviour has been seen for all versions of JDK 1.6 as far as I remember; it certainly happens with 1.6u3 and 1.6u4.

That bug report and related ones makes interesting reading: I can see now that Swing/AWT problems are probably behind a few problem reports of this kind we've had. I tried out the test case in that particular bug, and it does seem to be fixed in the JRE is claims to be fixed in. But looking at the horror-show that is XWM.java [1], I can believe there are other problems, and the behaviour will be different with different JRE versions. There's certainly scope for adding fixes/workarounds to the multiwindow mode internal window manager so that AWT does the correct thing, but I guess what I need to progress this is a test case I can easily run, and 'java -version' for the platform the test case should be run on [1] http://hg.openjdk.java.net/jdk7/jdk7/jdk/file/d58354a69011/src/solaris/c lasses/sun/awt/X11/XWM.java -- Jon TURNEY Volunteer Cygwin/X X Server maintainer menus.java Description: menus.java -- 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/
RE: Mouse offset when using java swing based gui applications
There's a bug reported against Java relating to this, with some more details. It claims to be fixed, but it still occurs. There's a small test case in the bug report. It makes many Java UI applications unusable with Cygwin/X. http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6434227 Richard -Original Message- From: Jon TURNEY [mailto:jon.tur...@dronecode.org.uk] Sent: 15 July 2010 14:38 To: cygwin-xfree@cygwin.com Cc: jonas_wink...@gmx.de Subject: Re: Mouse offset when using java swing based gui applications On 13/07/2010 22:56, Jonas Winkler wrote: > I just noticed a very strange behaviour of my Cygwin/X-setup.

We've had some similar reports before of problems with the mouse position reporting with Java applications, for e.g. [1], but I've never had a simple test case that has allowed me to reproduce it and investigate. So, I'd be very interested to see your simple Java application which demonstrates the problem. If you could also start the Xserver with the '-logverbose 3' option and attach your /var/log/XWin.0.log, that would be most helpful.

RE: Cygwin/X server -query fails with recent versions of Gnome GDM
Thanks for the analysis. I did try adding root and gdm /etc/passwd at
the cygwin end and the query then worked.
I agree that this is a bug in GDM - I will see about posting a report
there. Might be worth adding this to a FAQ in case GDM is not fixed.

Thanks for the packet capture, that helps a lot understanding what's

I don't think this speculation is well-founded. :-)
So GDM is doing the equivalent of:
$ xhost +si:localuser:root
$ xhost +si:localuser:gdm
... which fails, I'm guessing for the not entirely unreasonable reason
that
these users don't exist.
> I cannot find a workround for this.
You might try adding users root and gdm in your cygwin installation
(perhaps
by adding them to /etc/passwd)
If that works around the problem, I think it's probably a bug in GDM
that it
fails if these users don't exist.
Even after reading the manpage formerly known as Xsecurity ('man 7
security')
and the source, I'm really not clear about how this form of credentials
are
supposed to work, but it seems pretty clear that they can only work
locally.
Note that a server built with NO_LOCAL_CLIENT_CRED (or old enough to
pre-date
these credentials) will reject all si:localuser and si:localgroup
credentials,
so it seems GDM should be prepared for it to fail...
