DDraceNetwork

Hey so idk why, but since yesterday my ddnet client stopped working. I also downloaded the latest version, but that also just starts with a blackscreen. The really strange thing however is, when i use my old ddnet 12.5 version, that one starts.. kinda feel like my pc is pulling a prank on me.

amd gpu? https://ddnet.tw/news/amd-beta-opengl-crash/

no, I have an GTX 1050ti

BakedTrash

no, I have an GTX 1050ti

latest GPU driver installed from nvidia.com directly?

10:29

are there crash logs in %appdata%/teeworlds/dumps or %appdata%/ddnet/dumps Is it a laptop or desktop PC?

only one form 02.05 ... so guess thats not that

10:30

but ya just looked and there is a new grapics driver.. maybe that will fix it :D

ah well fuck.. my nvidea experience app has this shitty bug where i cant update stuff nvmnd then

just redownload a fresh copy from nvidia.com

do i need to uninstall the old one?

normally not

Hello, im having some issues while trying to start 2 clients. First client works normally, (almost) no issues. After starting second client it freezes while loading. After several seconds first client freezes too. And a several seconds after that pc completely freezes forcing me to hard reboot. I cannot kill frozen processes even with root privileges. OS is Artix Linux and gpu driver is Nouveau

10:48

i dont need 2 clients but its still some issue lmao

10:49

installed ddnet from aur btw

what your window manager? did you try to start both clients without full screen? why nouveau, these drivers aren't really great as far as i know? x11? enough RAM? enough VRAM?

windows manager is dwm yes pc still dying without fullscreen old gpu so no proprietary driver support x11 yes 2 gigs ram 1 gig vram

ok RAM and VRAM could defs be an issue on bigger maps can you look if these get full when u start the 2nd client?

ok

nope it does not get full

bomab

nope it does not get full

mhh really weird then, but I guess you have to live with that if nobody has a solution here. I never heard of a problem like this before, sry :/

thanks for trying to help heartw

texnonik

how to fix ddnet hz ?

i think i know why i have it :/ i have new video card and video card drivers are old will test it soon ...

12:37

Can you drop to a tty after the complete freeze?

Learath2

Can you drop to a tty after the complete freeze?

nope

bomab

nope

How did you figure even with root perms you cant kill the process?

i tried to kill process before complete pc freeze

can you ctrl+alt+f2 to start a tty session?

15:14

or can you log in through ssh?

Chairn

can you ctrl+alt+f2 to start a tty session?

i cannot change to tty after freeze

Chairn

or can you log in through ssh?

i didnt try it

15:15

if i change to tty before freeze it will just freeze on tty

15:16

probably because my pc trash

sounds like kernel issue

15:16

is the fan going full blown ?

Chairn

sounds like kernel issue

tried on debian too

Chairn

is the fan going full blown ?

nope

Okay, maybe we can get some logs out. How about starting the clients with ./DDNet "logfile 1.log" and ./DDNet "logfile 2.log"?

ok brb

Have you tried a reboot with the kernel magic sysrq?

part of the gpu driver sits on kernel

If that works that should ensure a fs sync before the reboot

Learath2

Have you tried a reboot with the kernel magic sysrq?

no

so you'd need to look in kernel log instead

15:18

tho if that crashes it, u wont really get anything

Yes, dmesg could have something interesting too

what's the magic keyboard combination on linux? ctrl+alt+sys?

u could start the client with software rendering and see if that also freezes it

15:19

if not => kernel issue

15:19

gpu related

alt+sys+{r, e, i, s, u, b}

LIBGL_ALWAYS_SOFTWARE=1 ./DDNet

Yeah, many things you could try, but none of us really know what it is so it'll be a fair bit of debugging

15:23

The place where the sysrq keys are handled means if even they don't work you are pretty much fucked

15:24

After the sys+r you can try dropping into a tty again, maybe in raw input you can get out

15:26

Sys+e will send TERM to everyone. Sys+i will send KILL. Sys+s will sync the fs. Sys+u will remount everything ro. Sys+b will reboot

well, i just tried sys b

15:27

it works

15:27

but sys+e didn't

There is also sys+v you can try after sys+r. That should forcefully try to get you a tty

ok logs dont have anything, time to try other stuff

Chairn

but sys+e didn't

Check your /proc/sys/kernel/sysrq the bitmask there controls what commands are enabled

sync seem to work, the led lights up when i press it

submit your pc to ddnet hq

Anyway. The sysrq commands are very powerful. If they cant get you out you are somehow stuck in some awful deadlock

15:33

Deeep within the kernel

Learath2

Check your /proc/sys/kernel/sysrq the bitmask there controls what commands are enabled

i only got a number, 176 (edited)

Its a bitmask

15:35

https://www.kernel.org/doc/html/latest/admin-guide/sysrq.html

i set it to 1, so it enables all

V might be a useful one here. Honestly they are all very useful though

sys-r does not do anything sys-v drops me to tty but tty is frozen

Learath2

https://www.kernel.org/doc/html/latest/admin-guide/sysrq.html

sys-e does not do anything

15:58

sys-o shuts my pc down

did you activate all function before hand?

16:01

echo 1 > /proc/sys/kernel/sysrq

yup

murpi

submit your pc to ddnet hq

send your exact coordinates

did u try LIBGL_ALWAYS_SOFTWARE=1 ./DDNet with both clients?

16:41

both ddnet clients

Jupstar ✪

did u try LIBGL_ALWAYS_SOFTWARE=1 ./DDNet with both clients?

trying rn

damn thats some massive lag

yes its software renderer

oh god

so it runs on the CPU

it works

16:52

my pc is suffering rn but it works

driver issue

yeah

16:53

guess u could report it, but maybe they dont care about such an old GPU anymore

who cares about some old unsupported gpu lmao

16:54

actually its the only linux driver which isnt supported

only 12 years old GPU, brand new

i guess should have tested 2 client thing when i was on freebsd suffering from audio problems

but why do you need 2 clients?

i dont

16:56

its just an issue

16:56

i can live with my pc dying when i run 2 clients

16:56

thanks

16:56

bomab

i can live with my pc dying when i run 2 clients

one last thing

yes

gfx_gl_major 1; gfx_backend opengl put this in f1
