I had checked the /var/log/syslog of my fathers computer who is running linux mint 18.01 xfce and his log is completely different then my log and he even doesn’t get this problem which I wasn’t getting in Ubuntu(unity)

i had Also install pixmap by sudo apt install pixmap

It happens when you use a transparent panel.

[smit_patil]

You saved my life,But where did you find this information cause I was searching for this every where and you just tell me in 8 words thanks again!!!.
now i have disabled the transparency of panel and not getting the same warning again.

But Does this mean that should not use transparent panel!!

I don't know but you have an acer laptop, so this has to be the problem.

FYI, there's been a lot of work upstream on panel backgrounds following this report;

[Zesty] Multiple applet crashes on login when using transparent panels

System: Host: Edge Kernel: 4.10.0-20-generic x86_64 (64 bit) Desktop: MATE 1.18.0 Distro: Ubuntu 17.04 I’m using Marco + Compton, standard layout with a few customizations: Both panels backgrounds have been set to “solid color” with 100% transparency I have added a multiload indicator applet to the top panel. When I login to my session, I have a flurry of applet crashes. It didn’t happen when the panels were not transparent. Can anyone else try and reproduce this? Thanks
