krunner BT from crash at the same time as Konsole
The krunner crash is almost certainly https://bugreports.qt.io/browse/QTBUG-40174 - see attached backtrace. Similarly the konsole crash matches https://bugreports.qt.io/browse/QTBUG-42985. Both are unfortunately only in Qt 5.5, which is currently a month behind schedule and due at the end of May. Note that the bugs suggest that ensuring there is always at least one screen will prevent these crashes. Thanks for taking the time to sort out my crashlog. My monitor swap was a one-time thing, so I don't need to get it fixed for me to be happy with KDE on my system. I just wanted to get the bug reported.
> Note that the bugs suggest that ensuring there is always at least one screen will prevent these crashes.
You're talking about what software is doing in response to monitor changes, right? Not physical connections.
Because I always had at least TWO screens connected. I never unplugged DVI-0. I went from DVI-0(1680x1050)+DVI-1(1920x1200) to DVI-0(1680x1050)+HDMI-0(1920x1200), with DVI-0+DVI-1+HDMI-0 as a temporary state. When I was done, HDMI-0 instead of DVI-0 was the "primary" display, showing the panel, so clearly some configurator shuffled stuff around.
Qt issue, see (there are more similar reports linked in comments): https://bugreports.qt.io/browse/QTBUG-42985 If you have further info, please report it there, to raise the awareness ;) It might be that this crash here is even already fixed, thought still others with bit different BTs remain. |
Application: konsole (3.0.1) Qt Version: 5.4.1 Operating System: Linux 3.19.0-15-generic x86_64 Distribution: Ubuntu 15.04 -- Information about the crash: This is almost certainly not Konsole's bug, but IDK which package is at fault, or how to get drkonqi to send the bug there if I did. krunner crashed at the same time as Konsole. (Will attach a backtrace from that to this bug.) Please reassign this bug somewhere appropriate, thanks. - What I was doing when the application crashed: old: DVI-0 (@0,150) DVI-1 (@1680,0) DVI-0 was the primary head (so the plasma panel showed there, etc.) change: plug in HDMI-0, unplug DVI-1. (in that order). .xsession-errors shows I temporarily had 3 screens. new: HDMI-0 (@0,0) DVI-0 (@1920,0) with HDMI-0 as primary. I *think* I had at least one of Konsole's 2 open windows on screen 1 (DVI-1), which went away. I had to use the monitor setup GUI to arrange my monitors again, with HDMI-0 logically to the right of DVI-0, instead of the other way around. And DVI-0 as primary again. (That's fine, IDK if it's worth trying to remember monitors by their EDID serial number or something.) I was just changing which connection i was using to connect my desktop to one of my monitors, to free up its DVI input. Given the order I did things, without overly clever EDID monitor ID detection my system couldn't know that it was actually connected twice to the same monitor. I also had to update my /etc/X11/xorg.conf. My xorg.conf is (now): Section "Monitor" Identifier "DVI-0" Option "PreferredMode" "1680x1050" Option "Position" "0 150" EndSection Section "Monitor" # Identifier "DVI-1" Identifier "HDMI-0" Option "PreferredMode" "1920x1200" Option "Position" "1680 0" EndSection #Section "Screen" Section "ServerFlags" # without this, one head on Intel, other on Radeon appears to work. # stop server from grabbing all the GPUs Option "AutoAddGPU" "false" EndSection Without an xorg.conf, KDE's graphical login comes up at a crappy rez. With it, it comes up spanned across my screens, instead of mirrored on each one, but at least my monitors are running at native rez all the time. Also, it's REALLY hard to get the GUI screen layout configurator to snap the 1680x1050 head to align with the BOTTOM of the other head, instead of the top or half-way up. With enough wiggling of the mouse, it is possible. (My bigger monitor is physically positioned a bit higher than my smaller monitor, so I want their bottoms logically aligned, so windows stay closer to the same physical height when dragging from one to another. This means (0,0) is off-screen, but that's rarely a problem.) In case it matters, I'm running an ATI 6870 GPU on Intel Sandybridge. Software is Kubuntu 15.04, stock versions of kernel and open source (mesa) graphics stack, no fglrx. I have a couple non-default desktop settings: breeze-dark theme, and the dim non-focused windows desktop effect. .xsession-errors: kwin_core: Successfully loaded built-in effect: "contrast" kscreen:
