Xpra: Ticket #199: vmware-gksu freezes xpra session


I haven't tested with proper "gksu" itself, but vmware-gksu freezes the session, probably when trying to grey the screen and steal focus.

I've got vmware-gksu installed, how do I make it misbehave? (works fine here when I tried via xpra..)

(also, there were a number of fixes recently with focus/window cleanup recently - maybe this is fixed already?)

I still have the problem. Running vmware-gksu on a (Xvfb-based) Xpra session locks it up for good - I can't input my password nor do anything.

latest trunk as of this writing, up-to-date Archlinux on client and server

Well, that's a PITA. The "current" version is gnome's polkit gksu and that worked ok after I started the gksu-server. But it failed when I tried as a user which did not already have a real desktop session running. I guess the polkit part piggybacks on the existing display connection? Who knows:

Then there's also the original gksu, but after downloading a gazillion dependencies, the Makefile is broken (tabs vs spaces) and even after fixing it doesn't build cleanly on Fedora 18:

libtool: link: gcc -g -O2 -Wall -g -O2 -o test-gksuui test-gksuui.o  \
    ./.libs/libgksuui1.0.a -lgtk-x11-2.0 -lgdk-x11-2.0 -latk-1.0 -lgio-2.0 \
    -lpangoft2-1.0 -lpangocairo-1.0 -lgdk_pixbuf-2.0 -lcairo -lpango-1.0 \
    -lfreetype -lfontconfig -lgobject-2.0 -lgconf-2 -lglib-2.0
/usr/bin/ld: ./.libs/libgksuui1.0.a(gksuui-dialog.o): undefined reference to symbol 'XkbGetState'
/usr/bin/ld: note: 'XkbGetState' is defined in DSO /lib64/libX11.so.6 \
    so try adding it to the linker command line
/lib64/libX11.so.6: could not read symbols: Invalid operation
collect2: error: ld returned 1 exit status

Adding -lX11 fixes that, then the ui build needs -lgtk-x11-2.0 added to fix yet another compile error.

Eventually, one can get gksu installed and it works ok via xpra too.. fullscreen and everything.

It looks to me like the vmware version is a fork/copy of gksu, which is GPLv2 so maybe someone can ask them for the source then we can figure out what it does different?

In gksu-2.0.1-1.tgz, we find:


The archive is the same as upstream and the patch is irrelevant to us (only applies on command exit)

And in libgksu-2.0.11-1.tgz, we find a source RPM!?:


The RPM contains:

$ cd ~/rpmbuild;ls -la *

To try to build on Fedora 18, I needed to patch the specfile and replace libgtop-devel with libgtop2-devel. But then:

rpmbuild -ba SPECS/libgksu.spec

Looks to me like this source RPM is just broken and does not build as it is. So, not only is this an outdated version, it has random patches that don't apply cleanly - is it really worth pursuing?

not going to deal with this for 0.9.x for sure

Old, closing - though focus/grabs will be revisited in 0.12
