I guess that in the unity env, there is a daemon which use libcanberra to provide sound theme for apps. While in the weston desktop, no sound deamon launched and hence no crash. Anyway, libcanberra-gtk3-module has direct dependency on gdk_x11_**, that should be removed. <blockquote cite="mid:20120508144225.GH22655@chaosreigns.com" type="cite"> <pre wrap=""> </pre> <blockquote type="cite"> <pre wrap=""> 2.

But if the wesont-terminal is launched from a remote terminal, for example, I used to launch app from a putty terminal, that breaks it. <blockquote cite="mid:20120508144225.GH22655@chaosreigns.com" type="cite"> <pre wrap=""> bet running weston SUID root breaks it.</pre> </blockquote> Do you mean  doing "sudo chown root /usr/bin/weston" and "sudo chmod +s /usr/bin/weston" will break it? According to my testing, the answer is "No".  My steps are: Open VT sudo chown root /usr/bin/weston sudo chmod +s /usr/bin/weston export <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">  XDG_RUNTIME_DIR=/tmp<o:p></o:p> export LIBOVERLAY_SCROLLBAR=0<o:p></o:p> <span style="font-size:10.5pt;mso-bidi-font-size:11.0pt;font-family: "Calibri","sans-serif";mso-ascii-theme- font:minor-latin;mso-fareast-font-family: 宋体;mso-fareast-theme-font:minor-fareast;mso-hansi-theme- font:minor-latin; mso-bidi-font-family:"Times New Roman";mso-bidi-theme-font:minor-bidi; mso-ansi-language:EN-US;mso-fareast-language:ZH-CN;mso-bidi-language:AR-SA" lang="EN-US"> <meta name="ProgId" content="Word.Document"> <meta name="Generator" content="Microsoft Word 14"> <meta name="Originator" content="Microsoft Word 14"> <link rel="File-List" href="file:///C:%5CUsers%5Czwu28%5CAppData%5CLocal%5CTemp%5Cmsohtmlclip1%5C01%5Cclip_filelist.xml"> <link rel="themeData" href="file:///C:%5CUsers%5Czwu28%5CAppData%5CLocal%5CTemp%5Cmsohtmlclip1%5C01%5Cclip_themedata.thmx"> <link rel="colorSchemeMapping" href="file:///C:%5CUsers%5Czwu28%5CAppData%5CLocal%5CTemp%5Cmsohtmlclip1%5C01%5Cclip_colorschememapping.xml"> <style> <!-- /* Font Definitions */ @font-face {font-family:宋体; panose-1:2 1 6 0 3 1 1 1 1 1; mso-font-alt:SimSun; mso-font-charset:134; mso-generic-font-family:auto; mso-font-pitch:variable; mso-font-signature:3 680460288 22 0 262145 0;} @font-face {font-family:宋体; panose-1:2 1 6 0 3 1 1 1 1 1; mso-font-alt:SimSun; mso-font-charset:134; mso-generic-font-family:auto; mso-font-pitch:variable; mso-font-signature:3 680460288 22 0 262145 0;} @font-face {font-family:Calibri; panose-1:2 15 5 2 2 2 4 3 2 4; mso-font-charset:0; mso-generic-font-family:swiss; mso-font-pitch:variable; mso-font-signature:-520092929 1073786111 9 0 415 0;} @font-face {font-family:"\@宋体"; panose-1:2 1 6 0 3 1 1 1 1 1; mso-font-charset:134; mso-generic-font-family:auto; mso-font-pitch:variable; mso-font-signature:3 680460288 22 0 262145 0;} /* Style Definitions */ p.MsoNormal, li.MsoNormal, div.MsoNormal {mso-style-unhide:no; mso-style-qformat:yes; mso-style-parent:""; margin:0cm; margin-bottom:.0001pt; text-align:justify; text-justify:inter-ideograph; mso-pagination:none; font-size:10.5pt; mso-bidi-font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:宋体; mso-fareast-theme-font:minor-fareast; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi; mso-font-kerning:1.0pt;} .MsoChpDefault {mso-style-type:export-only; mso-default-props:yes; font-family:"Calibri","sans-serif"; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;} /* Page Definitions */ @page {mso-page-border-surround-header:no; mso-page-border-surround-footer:no;} @page WordSection1 {size:612.0pt 792.0pt; margin:72.0pt 90.0pt 72.0pt 90.0pt; mso-header-margin:36.0pt; mso-footer-margin:36.0pt; mso-paper-source:0;} div.WordSection1 {page:WordSection1;} --</style>dbus-launch /usr/bin/weston clicked terminal icon on the weston panel to launch weston-terminal #In the weston-terminal export GDK_BACKEND=wayland sudo chmod ugo+rw /tmp/wayland* gnome-terminal & # that works fine ........... <blockquote cite="mid:20120508144225.GH22655@chaosreigns.com" type="cite"> <pre wrap=""> </pre> <blockquote type="cite"> <pre wrap=""> 5. brasero can not run, and no useful log printed. </pre> </blockquote> <pre wrap=""> What exactly did you see?

I found another issue that in the native weston mode,  rhythmbox will crash in libmmkeys.so which invokes libX11.so. But in the weston as X11 client mode, it works fine. It seems that  rhythmbox will request dbus service  from gnome-settings-daemon, if the service not privided,  rhythmbox will invoke X11 api and crash. Where should I report this bug? rhythmbox community or ubuntu? </body> </html>
