Re: SIGSEGV in xorg-1.8.2.0 during -resize operation

I was overjoyed to see that the release notes for the new X server release
mention support for resizing the X desktop with the windows desktop.

Unfortunately, it didn't work :(

I modified the xwin windows shortcut to run as follows:
C:\cygwin\bin\run.exe /usr/bin/bash.exe -l -c /usr/bin/startxwin.exe -- -resize

You need to quote the entire command you are passing to bash after -c


i.e, try C:\cygwin\bin\run.exe /usr/bin/bash.exe -l -c "/usr/bin/startxwin.exe -- -resize"

Then started the server at 1920x1200x32bpp while my ThinkPad was attached to
an external LCD.

When I detached the monitor to leave the office, X disappeared with signal 11
(log attached). Oddly, the log file didn't mention -resize as an argument to
XWin, but it did attempt to resize so I assume the feature was active.

There have been some reports of the X server segfaulting when the resolution changed, prior the addition of -resize support.


This is something which also needs to be fixed.

Note that, for reasons I've never understood, ThinkPad's resolution switching
utility always switches through 3-4 resolutions on its way to a new setting;
that might have something to do with the problem. The final resolution should
have been 1400x1050x16bpp.

I'm also attaching cygcheck's output and the .stackdump file in case they are
helpful.

Thoughts?

Never assume! :-)
