This is a 64-bit desktop machine using KDE in Leap 42.1. Video is nVidia GEForce GTX 670, nVidia proprietary driver version 361.26 installed "the hard way". KDE Plasma version is 5.5.95; KDE Frameworks is 5.20.0; Qt version 5.5.1; kernel 41.1.15-8-default. Desktop effects is active; compositor rendering backend OpenGL 3.1 I like to use the "Restore previous session" setting on login. Typically the "previous session" would include applications Thunderbird, Akregator and Knode. Until recently this all behaved well, with the applications opening on login as advertised. But, since an update to Plasma a few days ago, it hasn't worked well in the case of Thunderbird specifically. Akregator and Knode continue to startup on login as expected, but Thunderbird doesn't, and I have to start it manually. That's no big deal, but I'd like to understand why. I don't know if it's relevant, but in .xsession-errors:0 I get things like this: QUOTE kdeinit5: Got EXT_EXEC '/usr/bin/thunderbird' from launcher. kdeinit5: preparing to launch '/usr/bin/thunderbird' QXcbConnection: XCB error: 3 (BadWindow), sequence: 3680, resource id: 123731968, major code: 18 UNQUOTE but, even it that's relevant, it's 'way past my ability to interpret. Can anyone guide me, please, to a solution for this? There's another point that might or might not be related. Hitherto I'd been using a desktop scheme titled "Tragedy" - and had done so for years through a number of previous iterations of openSUSE and KDE. I believe it was/is a KDE4 package that might not have been updated for Plasma 5 etc. But it ran OK under Leap 42.1/KDE"5" until I applied the above-mentioned Plasma update, since when it hasn't worked. So, is there anything I can do about either or both of these matters, it, or are the (apparent) regressions simply a part of the march of progress? [In respect of the Thunderbird session start problem, I should perhaps add that I've tried disabling the "Tragedy" desktop scheme and selecting the default "Breeze" scheme, but it didn't help.] -- Robin K Wellington "Harbour City" New Zealand -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
