[arch-general] plasma 5 crashing
Fully updated from testing repo. Since update to plasma 5.5 I am getting periodic crashes of plasmashell -trace back below. Seems to be connected with dri/swrast_dri.so. i915 graphics so not sure why swrast_dri is called - but then again not sure what that does exactly (sounds like software rendering). Anyone got suggestions or seen similar. plasma restarts itself and things go normally for a while until the next crash. gene --- trace back Application: Plasma (plasmashell), signal: Segmentation fault Using host libthread_db library "/usr/lib/libthread_db.so.1".

For anyone having this kind of problem some additional useful info might be obtained by running the suggested commands in the page at http://dri.freedesktop.org/wiki/glxinfo/ - and getting at some 3d rendering info specifically when the system has a problem indicated by the fact that the rendering is falling back to the swrast_dri driver. Any chance this report relates to failed graphics drivers which may originate in bugs in the mesa/plasma/X etc code - but at least some initial info showing where there is a problem may point to where to look for more problems so narrow down where the initial failure occurs? -- mike c
