Rootfs problem : random logouts


rootfs linaro-buster-alip-dragonboard-820c-407.img.gz

i am using the 407 rootfs in db820c, it randmoly logs out in gui, need to login every time it logouts and closes the process opened in previous log in .
please suggest.


Is it a crash related to: Facing crash issues in Kwin-x11 5.14.5
Can you try the proposed workaround (updating mesa).

aftr trying this

echo “deb unstable main contrib non-free” >> /etc/apt/sources.list
sudo apt-get update
sudo apt-get -t unstable install libgl1-mesa-dri

board does not boots to ui, it stops at terminal login.

Facing same issue after applying work-around.

if it doesn’t reboot can you journalctl --boot=0 > journal.log and attach that? (Or if it rebooted, then use --boot=-1)

@robclark,Thanks for the reply.
This rootfs is not having the work-around. While trying to install some packages board crashed to login screen.
Refer line number 945 :

Log of rootfs with workaround, UI is not up

hmm, I was expecting to see Xorg logs in the journal… maybe you need to attach /var/log/Xorg.0.log from the two cases?


libgl1-mesa-dri is 18.3.6-2

journalctl --boot=0 > journal.log -
Xorg.0.log -


not really seeing any useful hint in the logs. Any chance of attaching gdb to Xorg process before it crashes and getting a backtrace?

backtrace log

can you get that with mesa debug syms installed?

(I think on debian that would be something like ‘apt install libgl1-mesa-dri-dbgsym’)


installed the libgl1-mesa-dri-dbgsym in debian.

here is the latest gdb log

if i try to use the 19.3.1-4 unstable version Xorg will not load.

journal.log_19.3.1-4 -

Xorg.0.log_19.3.1-4 -
