#

seems like it's calling it more than once at a time

hidden ore Aug 18, 2022, 1:15 AM

#

what do you mean ?

stray hemlock Aug 18, 2022, 1:15 AM

#

you must not have if you don't remember doing it, try sudo systemctl restart lightdm and then reboot

hidden ore Aug 18, 2022, 1:16 AM

#

stray hemlock Aug 18, 2022, 1:17 AM

#

ok check journalctl -xeu lightdm.service

hidden ore Aug 18, 2022, 1:18 AM

sudo system disable --now lightdm

hidden ore Aug 18, 2022, 1:21 AM

lusty root Aug 18, 2022, 2:05 AM

#

So how is it going?

hidden ore Aug 18, 2022, 2:05 AM

#

stray hemlock Aug 18, 2022, 2:06 AM

stray hemlock append this `logind-check-graphical=true` on a line below [LightDM]

this line will make sure your graphics drivers load before lightdm does

hidden ore Aug 18, 2022, 2:06 AM

#

stray hemlock append this `logind-check-graphical=true` on a line below [LightDM]

is already true

stray hemlock Aug 18, 2022, 2:06 AM

stray hemlock Aug 18, 2022, 2:16 AM

practice in vm for a while before you put on your pc

hidden ore Aug 18, 2022, 2:16 AM

#

TetraShot#1015

#

stray hemlock Aug 18, 2022, 2:16 AM

never use C

even man pages says it's dangerous

hidden ore Aug 18, 2022, 2:16 AM

#

hidden ore Aug 18, 2022, 2:17 AM

hidden ore Aug 18, 2022, 2:17 AM

#

stray hemlock

stray hemlock Aug 18, 2022, 2:20 AM

#

everything is well documented, and I don't have anything I don't want or need

#

hidden ore Aug 18, 2022, 2:21 AM

#

do you know any source for learning linux ?

hidden ore Aug 18, 2022, 2:21 AM

#

stray hemlock been learning everything myself with linux, programming, data science, etc lol

ooo cool

stray hemlock Aug 18, 2022, 2:21 AM

#

actually yeah, let me find it

#

there's a free course by the linux foundation, free 90 day trial

#

you can finish it all in 90 days no problem

#

but have to pay for the cert

#

linus torvald is even in the course

hidden ore Aug 18, 2022, 2:22 AM

#

stray hemlock but have to pay for the cert

oh I can't do that

stray hemlock Aug 18, 2022, 2:22 AM

#

no but you can take the course to learn

#

I can't seem to find it now

#

anyway, https://www.coursera.org/courses?query=linux you can apply for financial aid on most coursera courses and will get approved in 14 days, I have 3 proffesional certs from coursera already
