Created attachment 8091 Screenshot of the sensor plugin applet and its settings When sensor-plugin applet is added to the vertically oriented xfce4-panel, the displayed text is rotated 90 degrees instead of being displayed horizontally as all other applets do. Screenshot attached. (Seen after upgrade to Fedora 29, reported also to Fedora bugzilla as #1647330)
Easy to explain: Xfce introduced a new mode, called 'deskbar mode', which is the old vertical mode. The new vertical mode is really vertical, rotated by 90 degrees. Netload plugin, sysload plugin all behave the same. You can redraw your bug at Fedora and explain the reasons. Originally, I had bug reports for not supporting the deskbar mode, you should have found them. Second, few weeks ago, another guy didn't find the old bugs and neither the new mode. However, you can try the latest versions of date or orage plugin, the "window button" plugin, and see whether they still do not support the three modes correctly in the new style. for what you want, change the panel to "deskbar" mode.
OK, thanks for the explanation. Of course, it would have been nice if XFCE could detect the upgrade and adjust the configuration accordingly, so that the old configuration with old XFCE works the same as the new one. I have switched my Panel to the deskbar mode: - orage clock is horizontal in both modes - sensors applet is horizontal in the deskbar mode only, thanks for the tip - the most annoying thing is how the Workspace Switcher behaves: I use 3x3 workspaces. In the new vertical mode the workspaces are organized as 1 4 7 2 5 8 3 6 9 while in the Deskbar mode they are organized as 1 2 3 4 5 6 7 8 9 and indeed, changing the Panel mode from Vertical to Deskbar or vice versa flips the contents of the virtual desktops. So when I am at virtual desktop 1 (upper left one in both modes) and switch to the next workspace to the right side, I get different windows depending on the mode of the panel, on which the workspace switcher is on. I wonder what would happen if I create two panels in different modes, and put a workspace switcher to each of them.
:) So please try out what happens and also talk to the maintainers or developers of the workspace plugin; they might not know the odd behaviour. Also, orage clock is then not correct for the vertical mode --> leading to confusion of its users. Another bug report :)
