I lately put in ubuntu18.04LTS alongside home windows 10 on my laptop computer.Lately(after a system replace)the gnome began to crash randomly.First I acknowledged this whereas I used to be taking part in some video games on Wine,as the sport stopped responding to any motion,reminiscent of keydown or mousemove.Then it happed when utilizing VLC,the interface seems,however the video not.After I used killall vlc,it did not work.The interface keeped till subsequent boot.Now I exploit firefox to browse the online and it will possibly crash with out notification——the sidebar froze and the title bar of all of the home windows disappered so I actally can not contrl them.And terminal not working typically when freeze(utilizing Ctrl+Alt+T donnot work)

I do not use any sort of extension of gnome .

My {hardware}:intel 8265U | graphic card-nvidia Geforce MX250（Actally not utilizing,I at all times use the intel UHD620 contained in the cpu) | teamgroup 16GB DDR4

that is the log file from final crash./var/log/apport.log
