Created attachment 109885 [details] KWrite running over SSH, with no toolbar and configure dialog icons When I run Kate or KWrite over an SSH connection with X forwarding, or via X2Go, the toolbar icons are not displayed, but rather are replaced with text labels. Similarly, the icons in KWrite's Configure dialog are missing. (See the attached screenshot.) The following error message is displayed on the console when the application first starts up: libGL error: failed to load driver: swrast The problem does not seem to affect other KDE applications.
(In reply to Tristan Miller from comment #0) > The problem does not seem to affect other KDE applications. I've just noticed that the problem also affects Okular. This may be something related to the X server or video driver rather than KDE. https://askubuntu.com/questions/745135/how-to-enable-indirect-glx-contexts-iglx-in-ubuntu-14-04-lts-with-nvidia-gfx seems vaguely relevant.
Upon further testing I can confirm that this is a problem with the X server, or maybe with how it's configured by default on my distribution: <https://bugzilla.suse.com/show_bug.cgi?id=1032509> Closing as this isn't a KDE problem.
Correction: The X configuration wasn't the only issue. It is also necessary to set XDG_CURRENT_DESKTOP=KDE before launching any KDE application, as described here: <https://forums.opensuse.org/showthread.php/526296-ssh-X-and-plasma>
