I was just about to say we only need the 36 file or we fight with
x11-common, and i know who wins! ;-)
I was going to suggest on 36
# Some boinc headers needed so if some poor admin stumbles across this
he knows where it came from...
# This file is sourced by Xsession(5), not executed.
# If xhost (from x11-xserver-utils) is installed, use it to give access
# to the X server to any process from the same user on the local host.
# Unlike other uses of xhost, this is safe since the kernel can check
# the actual owner of the calling process.
if type xhost >/dev/null 2>&1; then
id -u $BOINC_USER >/dev/null 2>&1 && xhost +SI:localuser:$BOINC_USER || :
I have tried removing my xhost hack from the lightdm.conf and rebooted.
The AMD GPU was not detected by boinc at reboot, (using 36 file) so GPU
tasks not starting.
Then logging in as normal - started boincmgr (see the non-started tasks)
xhost does show boinc has been added as +SI:localuser:boinc
A command line "sudo boinc-client restart" works as expected and the GPU
I need to spend a little time to verify what is happening here, there
may be something i am not understanding.
i will add some debugging lines into 36 to see when exactly it starts
and if there are any errors over the weekend.
May i ask - if either of you have an AMD card - did you find - that
boinc automatically starts running GPU tasks on bootup?
