I suspect that I'm seeing the same issue as the original poster. Running xfce4-settings 4.11.3, without any of the published patches.
When unplugging the HDMI cable I very often get an 'xfsettingsd' crash. This results in Xfce reverting to some fallback, default (and ugly) theme, as well as the font size changes. When it crashes, I get this message in the console: liv@liv-inspiron:~$ The program 'xfsettingsd' received an X Window System error. This probably reflects a bug in the program. The error was 'BadRRCrtc (invalid Crtc parameter)'. (Details: serial 1191 error_code 148 request_code 140 minor_code 21) (Note to programmers: normally, X errors are reported asynchronously; that is, you will receive the error a while after causing it. To debug your program, run it with the --sync command line option to change this behavior. You can then get a meaningful backtrace from your debugger if you break on the gdk_x_error() function.) l A quick and dirty, but useful solution is to then run 'xfsettingsd' from a terminal. This reverts from the ugly theme to the usual desktop appearance settings. In any case, I've just upgraded from 4.11.2 to 4.11.3, and this bug has suddenly become all the more visible... -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to nvidia-graphics-drivers in Ubuntu. https://bugs.launchpad.net/bugs/1308105 Title: Xfce resets TV mode to NULL when power cycled To manage notifications about this bug go to: https://bugs.launchpad.net/mythbuntu/+bug/1308105/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
