Bad background colours and formatting problems are because evolutio doesn't support CSS and HTML styles properly. It always has been more bloated than other apps, I would recommend something like Thunderbird instead. As for lock screen do you have xscreensaver installed? Check its settings and see if running xfce4-screensaver gives errors.

Until now I was subscribed to Ubuntu Studio devel and users mailing lists only, I'm unsure if I have to join Xubuntu and/or Ubuntu users too. Perhaps Xubuntu is the right choice, since IIUC Ubuntu Studio quasi is Xubuntu. I've got issues with Evolution, when using Ubuntu Studio Quantal amd64, so by Menu > System > User and Groups I add a test user. I checked the same options that are checked for the original user. Those options are - Access external storage devices automatically (default for the original user) - Configure printers (default for the original user) - Connect to Internet using a modem (default for the original user) - Monitor system logs (default for the original user) - Share files with the local network (default for the original user) - Use audio devices (default for the original user) - Use CD-ROM drives (default for the original user) - Use VirtualBox virtualization solution (manually add to the original user too) Perhaps useful: $ sudo cp -pr /home/test_user /home/test_user.default~ And after starting the first session I switched to tty1 and run: $ sudo cp -pr /home/test_user /home/test_user.1_session~ $ sudo apt-get update $ sudo apt-get install evolution I removed Evolution some time ago, so I had o reinstall it. I was asked to restart the computer, so I restarted the machine. When I launched Evolution by the menu, the "Account Assistant" started with too much delay. Some text was missing, I anyway was able to use the assistant and used the same settings as I use with Ubuntu Studio Precise's Evolution. After setting up, I closed Evolution and launched it again by a terminal emulation. I was able to receive mails, but all GUI features are working in slow motion. Editing mails doesn't work. Background colors are bad and the editor window is unusable. I avoided to import mails or to share mails with other installs. Note, the import option didn't work for the original user, sharing emails was possible, but I still had issues with sending, receiving, editing, and performance. test_user@qrc:~$ evolution (evolution:2463): e-web-view.c-WARNING **: Disabling webkit plugin: QuickTime Plug-in 7.6.6 (evolution:2463): e-web-view.c-WARNING **: Disabling webkit plugin: DivXŽ Web Player (evolution:2463): e-web-view.c-WARNING **: Disabling webkit plugin: Windows Media Player Plug-in 10 (compatible; Totem) (evolution:2463): e-web-view.c-WARNING **: Disabling webkit plugin: VLC Multimedia Plugin (compatible Totem 3.4.3) (evolution:2463): libebackend-CRITICAL **: e_extension_get_extensible: assertion `E_IS_EXTENSION (extension)' failed ** (evolution:2463): CRITICAL **: e_mail_formatter_clear_headers: assertion `E_IS_MAIL_FORMATTER (formatter)' failed ** (evolution:2463): CRITICAL **: e_mail_formatter_set_default_headers: assertion `E_IS_MAIL_FORMATTER (formatter)' failed (evolution:2463): e-web-view.c-WARNING **: Disabling webkit plugin: QuickTime Plug-in 7.6.6 (evolution:2463): e-web-view.c-WARNING **: Disabling webkit plugin: DivXŽ Web Player (evolution:2463): e-web-view.c-WARNING **: Disabling webkit plugin: Windows Media Player Plug-in 10 (compatible; Totem) (evolution:2463): e-web-view.c-WARNING **: Disabling webkit plugin: VLC Multimedia Plugin (compatible Totem 3.4.3) (evolution:2463): e-data-server-ui-WARNING **: ENameSelector: Could not load "Personal": Cannot open book: Address book does not exist For the original user I solved the address book issue, but editing anyway only sometimes was possible. Claws does work for Quantal, but with Claws I can't share mails with other installs.
